There is a risk of isolated thunderstorms today as increasingly unstable air moves over our area this afternoon. Clearing and sunshine ahead of the next approaching low pressure system will add to the afternoon instability according to the NWS.
It should be noted for anyone venturing into the mountains today, that snow levels have lowered and will be coming down further. Significant, wet snow will continue to fall on Mount Shasta today with the snow level currently near 7kft falling to around 5500 feet. The Mount Shasta Avalanche Center`s Old Ski Bowl station at 7600 feet has recorded 11 inches of new snow in the last 24 hours.
Meanwhile, KMAX is reporting a temperature of 27 degrees Fahrenheit near the top of Mount Ashland, and the ski area webcams indicate some snow mixing in with rain at the base area. Additional accumulations of 1 to 3 inches are expected on Mount Ashland, 3 to 6 inches on Mount Shasta, and lesser north and east of Mount Ashland.
This cold and windy pattern is expected to continue through the weekend and into next week as a series of low pressure systems and fronts move through our local area.
A Red Flag Warning means that low humidity combined with heat and gusty winds may cause any fires that start to spread rapidly and uncontrollably. Extreme fire behavior is possible, and fires will be difficult to extinguish. Read more

A Message From Klamath County Emergency Management:
The NWS in Medford has updated portions of their storm forecast, to include more rain than originally thought and that the Sprague River will reach minor flood stage at the monitor in Beatty by Tuesday afternoon. It is not a hard and fast rule, but it generally takes another 12 hours for the high water to reach the town of Sprague River, and another 12 hours after that for the high water to reach Chiloquin. Minor flood stage means that the river will be out of its banks, but it’s unlikely as of now that it will affect structures. The situation may change depending on how much rain actually falls.
The river is forecast to crest about one foot lower than the area saw in February 2017. Several structures (barns and outbuildings) were affected in 2017, but no residences were flooded.
There are a few hardware stores in Klamath Falls that have sandbags and sand in stock, if you think you may need them. At this time Klamath County Emergency Management is not furnishing them.
The best thing to do for preparedness is to be aware of the potential hazards. Avoid river edges, as water may be flowing swiftly and may be full of debris. Winds are also forecast to be strong, which may cause water-saturated root systems to down some trees. Do not drive through water, as road surfaces may be washed away and it may be deeper than you think.
Latest Statement From NWS Medford Regarding Storm:
All attention shifts to an atmospheric river (AR) event expected to deliver periods of moderate to heavy rain across the area beginning Saturday night along the coast, then spreading inland west of the Cascades on Sunday…and then across northern California and east of the Cascades Sunday night into Monday. The moisture feed for this event has origins in the tropics and this will take direct aim on our forecast area. Model ensemble IVT (Integrated Water Vapor Transport) is shown to be in the top 1 percent of climatology. This means it is a very wet system for this time of year and could produce rain amounts that challenge records for early April.
We are forecasting a wide area of 4 to 8 inches of rain across Curry County and into portions of western Siskiyou County. Looking back at some of the April records for Brookings, a 2-day rainfall of 7.76 inches was recorded April 13-14, 1937. More recently, just behind that record, is 5.32 inches set on April 6-7, 2015. If the forecast holds, this could be one of the top 5 precipitation events for Brookings for April. Rainfall amounts of 2-5 inches will be common from the coast to the Umpqua Valley and the Cascades, as well as in the Mount Shasta Region. East side areas will have 0.50-1.50 inches of rain with up to 2.50 inches in the mountains. For Medford, the highest 2-day rainfall for April was 1.70 inches set April 12-13, 1912. More recently, Medford had 2-day rainfall of 1.54 inches in April 17-18, 2000. We are forecasting 1.00-1.50 inches of rain here over the 2 days, which would fall in the top 10 for April.
Of course, all this brings the risk of rapid rises on area streams, creeks and rivers and also the threat of slides and debris flows. The uncertainty exists in exactly where the heaviest rain bands will set up and how fast the system moves south and east of the area. Numerous flood watches have been issued and more may be added as we gain confidence in where the heavier bands will set up. Snow levels for this event should be up at 7000-8500 feet, so we`re not anticipating large impacts due to snow. An upper trough offshore will finally give the front a push eastward Monday night, so the heavier precipitation should taper off.
Below: Water Vapor Image Of Approaching Atmospheric River
The latest information from NWS Medford indicates increased concern about flooding. Heaviest rain for local region expected Sunday night into Monday night.
Wet weather will continue this weekend trough at least early next week. The first front is quickly moving east of the Cascades. A brief break in the steady precipitation is expected tonight into Saturday from the Cascades eastward, but another front will bring steadier precipitation back to coastal areas and then the Umpqua by Saturday morning.
Then, an atmospheric river (AR) will take aim on the forecast area Saturday night through Monday. With a source of moisture from near Hawaii, it will feature heavy rain and snow levels above 7000 feet. Snowmelt and increased runoff will result in significant rises to area rivers, streams, and creeks. Models have been consistent in showing the main heavy rain area from Curry County southward into western Siskiyou County with a wetter trend across northern California and portions of the East Side.
As such, small stream and urban flooding is likely in those areas, and main stem river flooding is possible. Forecast graphics below have been updated.
One front is quickly moving east of the area with a break in precipitation for most areas tonight. Another front will arrive at the coast late tonight/Saturday with steadiest precipitation west of the Cascades. That front will set up over the area with low pressure areas riding along it to maintain periods of moderate to heavy rain at the coast Saturday night through Monday.
Heavier precipitation will then push into northern California and east of the Cascades Sunday night through Monday night.
Latest model data have trended wetter across northern California (Shasta Region) and over portions of the East Side late Sunday through Monday. We have added Flood Watches for portions of south-central and SE Siskiyou Counties as well as east of the Cascades.
Snow levels above 7000 feet and heavy rain late Saturday through Monday will result in significant rises to area rivers, streams, and creeks, especially west of the Cascades and in Siskiyou County. There is increasing concern for flooding Saturday night through Monday night.
A few main stem rivers are expected to reach action stage/bankfull, and latest information is showing the Sprague River near Beatty reaching minor flood stage by Tuesday due to a combination of rainfall and snowmelt. We encourage you to keep a close watch on river forecasts, as well as our general forecasts and forecast discussions.
Landslides and debris flows are possible with this event. The Hooskanadan slide area could be particularly vulnerable to this heavy rain event.
Enhanced flash flood threat for wildfire burn scars, including the Klondike and Chetco Bar with peak rainfall rates of 0.50-0.75 of an inch per hour possible late Saturday night through Sunday evening.
Snow impacts will be minimal during the daytime, but there is potential for snow impacts across the high elevation areas like Crater Lake.
Below: Latest radar returns showing passing rain showers ahead of an atmospheric event that is expected later this weekend.
An Atmospheric River event with significant rain is expected this weekend
We have been talking about this developing storm in our breaking news app for a couple of days now. A strong rain storm (Atmospheric River) that has tapped moisture from the Hawaii area is expected to arrive in our area on Saturday. The rain is expected to continue into Monday with several inches expected along the coast and around 1/2 to an inch of rain expected in the Klamath Falls area. Areas of flooding are possible and rivers are expected to rise. The heaviest rain is expected Saturday into Monday. The weather service will be watching for potential land slides and other hazards as we get closer to the weekend.
Above: A forecast model showing an AR event with moisture from Hawaii streaming into our area.
Above: A storm timeline as we head into the weekend.
From the NWS Medford:
An active and wet spring weather pattern continues. One front will approach the forecast area this afternoon and move through on Friday, bringing with it moderate rain and windy conditions to portions of the forecast area.
A brief break in the steady precipitation is expected Friday night into Saturday morning. Then, an atmospheric river (AR) will take aim on the forecast area, and the source of the moisture is near Hawaii, so it will feature heavy rain and snow levels above 7000 feet. Snowmelt and increased runoff will result in significant rises to area rivers, streams, and creeks. Models have trended stronger with this AR, so small stream and urban flooding is likely, and main stem river flooding is possible.

Stormy Pattern With Rain and High Elevation Snow Expected To Return Wednesday
The high pressure system that has been responsible for our clear skies and warmer days is beginning to break down. A somewhat weak frontal system is expected to pass through Tuesday night (Tuesday should still be a warm day at partly cloudy and 62) into Wednesday followed by a stronger front later in the week around Friday into Saturday that will likely provide rain for the Klamath Falls area and high elevation snow.
From the NWS Medford:
You may be wondering if any of this precipitation will fall as snow in the mountains. Long answer short is…yes. The more nuanced answer is that snow levels will range from about 4000 feet to 6000 feet during the periods of precipitation. 5 to 10 inches of snow are expected in the Cascades, Siskiyous, and high terrain of Siskiyou County above 5000 feet Friday into Saturday.
We hope you enjoyed our taste of spring, we sure did! Hopefully it will return again soon. However, forecast models show an active weather pattern for the near future.
More Snow Followed By Warmer Sunny Weather Into Weekend
The latest forecast information suggests that our region will see another snow storm early Tuesday morning. Right now the storm appears to be more of a high elevation snow maker, but around an inch or two of slushy snow or possibly snow mixed with some rain is possible locally here in Klamath Falls. The storm should begin to impact the area between about 4am or 5am and begin to wind down around 11am according to current forecast data from the NWS.
One thing to consider with this incoming storm is that the snow is expected to fall in a relative short period of time. The higher elevations may see up to 2-4 inches (6-8 inches in higher elevations such as Crater Lake, Diamond Lake Etc) of snow in a short 6-12 hour period of time. The expected snow fall rates could cause travel disruptions on areas of Highway 140 between Klamath Falls and Medford as well as Highway 97 north of town (generally from Modoc Point north).
Above: An aerial image taken in Klamath Falls about 2:45pm yesterday after an unexpected snow storm arrived in the morning hours.
Due to the incoming storm, a winter weather advisory has been issued for the higher elevations of Klamath County.
Areas in purple depict the winter weather advisory currently in effect. Areas of Highway 140 West and Highway 97 North could see travel disruptions early Tuesday morning. Snow is possible late Monday night into Tuesday morning. The precipitation is expected to turn showery in nature in the Tuesday afternoon hours.
Above: Current snowfall forecast for a new snow storm expected Tuesday morning.
Warmer Weather Expected Soon
After the passage of Tuesday’s storm, the NWS Medford expects clearing skies and warmer temperatures into the weekend for our region. We could be looking at a high of 55-60 degrees by Sunday with clear sunny skies.
Winter Weather Advisory issued March 10 at 10:58PM PDT until March 12 at 12:00PM PDT by NWS Medford
…WINTER WEATHER ADVISORY IN EFFECT FROM 5 AM TO NOON PDT TUESDAY…
* WHAT… Snow expected. Total snow accumulations of 2 to 4 inches.

Weather Alert: Moderate To Heavy Snow Possible In Klamath Falls Today
Winter Storm Warning Today
The front that has brought heavy rain and snow to the forecast area has moved south into Northern California and will move back north to bring another round of moderate to heavy snow to areas Tuesday into Wednesday. Precipitation associated with front will push east of the forecast area Wednesday.
The NWS in Medford currently has an internet outage. However they were able to send screen shots of warnings and Klamath Falls is currently under a winter storm warning. About 6-8 inches of wet snow are possible for Klamath Falls today into Wednesday.
Periods of heavy snow expected east of the Cascades to include Klamath Falls, Lakeview, and Highway 97.
Long duration heavy snow event is likely in portions of Siskiyou County, with highest impacts above 3500 feet. The snow level will be right around Mount Shasta City.
Weather Update 2-25-19 1:40pm – Snow Expected Soon High Winds Currently
We have been very busy with numerous weather related incidents locally today. A semi truck has blown over on Highway 140 East, and high winds have snapped several power poles in the Merrill area.
We have been in contact with the NWS in Medford reporting information to them, and they have recently updated us on the immediate forecast for Klamath Falls.
The stalled frontal boundary north of us is expected to be pushed south in a few hours. Late this afternoon we should see about 2-3 inches of snow in blowing conditions. According to the NWS, the visibility in our local area could be very low at times in blowing snow. Snow should arrive in Klamath Falls around 4pm according to a forecaster. We should see some snow into Tuesday morning and then it should change over to rain in the morning after around 10am.

A High Wind Warning means a hazardous high wind event is expected
or occurring. Sustained wind speeds of at least 40 mph or gusts
of 58 mph or more can lead to property damage. Travel will be
impacted, especially for high profile vehicles.
The atmospheric river is now over parts of Oregon but a stalled frontal boundary is keeping the bulk of the precipitation north of Klamath Falls.
Above: infrared imagery taken at time of this posting shows Klamath Falls just south of the storm.
We have had several reports of snow falling so fast that it is difficult to see while driving along areas of Highway 97 in the higher elevations north of town. Highway 58 is also currently reported as getting heavy amounts of snow. West of the Cascades large amounts of rain are falling.
The NWS expects the stalled front to get a push south Monday afternoon around 4pm. This means we may see a few hours of snow around that time as the front moves through the local area. Some snow is also possible Tuesday afternoon as the front is expected to retreat back northward.
Expected snowfall amounts have recently been revised for the Klamath Falls area and it no longer looks like we will see the 4-6 inches that were advertised earlier with this storm. According to a weather forecaster in Medford, Klamath Falls may possibly see 1-2 inches of snow Monday afternoon starting somewhere around 4pm if the front pushes south as they expect.
As always we will update with more information as it becomes available.
Atmospheric River Expected To Cause Extended Period Of Rain & Snow
First off, what’s an atmospheric river? It’s a plume of moisture that originates in the tropic regions and then is transported to the west coast.
Below is one of the forecast models showing an atmospheric river aimed at Oregon for this incoming storm. The moisture plume extends from Oregon to Hawaii.
Extended Period Of Rain And Snow
Light snow is expected late Friday night into Saturday afternoon. According to the latest information from the NWS, they are expecting an extended period of precipitation for us starting as snow and then changing to rain. The precipitation is likely to be a 4-5 day event.
Currently about 4-6 inches of snow are expected for Klamath Falls from Saturday into Monday. A changeover to rain is likely overnight Sunday or Monday morning. The changeover timing depends on the storm track and several other factors.
This precipitation event is expected to last Saturday into Wednesday at least. A cold front is also expected to stall over Oregon during this time adding to the precipitation amounts. All of this combined with a strong jet stream brings together a storm that is capable of producing very large amounts of snow and rain over an extended period of time.
Above: Snow amounts expected into Monday before is expected to change to rain. 36 inches of snow are possible at Lake Of The Woods and over 50″ possible at Crater Lake.
Above: Rain expected after the change from snow into Wednesday.
Hazards You Might See:
Travel: Highway 97 North, Highway 140 East & West, and roads to Diamond Lake and Crater Lake could become hazardous for travel and highly impacted by this storm. Winds are also expected at the higher elevations possibly causing drifting snow. Snow plows and road crews are likely to be overwhelmed with a storm like this in the higher elevations.
Flooding & Landslides: right now it looks like most of the flooding problems will be over on the west side and coast range. However, we have been told the NWS will be watching rivers in our area closely as well. Other hazards include the possibility of isolated white outs, impassable roads, slower response times from emergency services and power outages.
A few things to keep in mind: Forecasts are educated guesses and storms don’t always behave as expected. We might see more or less precipitation or a longer or shorter period of snow and rain depending on the storm track. How much water our snow (and ground) can absorb also will be a factor for any flooding we might see in our local area.
Over the next few days, conditions will be present for impressive amounts of rain and snow so expect stormy weather Saturday into Wednesday at least.
We will keep an eye on all of this and update you as needed. The NWS will no doubt have a very busy next couple of days keeping us all informed about this incoming storm.
As always, real time alerts will be posted to our breaking news service for coverage of any potential events related to this storm.
According to the NWS Medford, an Atmospheric River event is possible for our area and region beginning Saturday night. The details of this event are still uncertain but depending on the timing of the mix of cold air and moisture we could see either a significant amount of snow, rain, or a combination of both. Flooding of small streams and rivers is a possibility and we will be watching all of this close as the NWS updates us.
We will have more information about this developing weather story tomorrow as the details get worked out and we get closer to the timing of the event.
A significant amount of moisture is expected to move into the area later this weekend and last into at least early next week as two fronts impact the area while moisture streams up from tropical origins. Snow levels will be higher overall, but heavy snow is expected for the Cascades, Siskiyous, and higher elevations in western Siskiyou County. Meanwhile, heavy rain is expected along the coast, coastal mountains and lower elevations in western Siskiyou County.
Above: Forecast 72 Hour precipitation early Sunday morning through early Wednesday morning. This is subject to change and is a current estimate. The above map is a precipitation estimate and doesn’t depict areas of rain and snow.
Above: A forecast tool indicating a plume of moisture (Atmospheric River) that is expected to setup and transport moisture from the Hawaii area to Oregon and Northern California.
Right now plan on the possibility of a significant amount of precipitation in the mountains and possible flooding and travel disruptions in our region.
Additional weather warnings, watches, and alerts may be issued.
Winter Storm Watch issued February 21 at 2:29PM PST until February 25 at 10:00AM PST by NWS Medford

National Weather Service Medford, OR
225 PM PST Thu Feb 21 2019
...Flood Potential Outlook for quick river rises, main stem river
flooding, and the potential for snow melt flooding on rivers and
streams in the following counties in California...Modoc...Siskiyou
and in Oregon...Coos...Curry...Douglas...Jackson...Josephine...Klamath...Lake...
.At atmospheric river will bring a good chance for periods of heavy
precipitation over Coos, Curry, and Western Siskiyou Counties Sunday
through Tuesday and possibly longer. A front will likely stall over
the forecast area late this weekend with waves of heavier precipitation
moving through. The front will push through the area by early or the
middle of next week. 4 to 8 inches of rainfall are possible at the coast.
Confidence is low on how much rainfall and timing of heaviest rainfall, but
recent data have increased the chance for significant river rises and
flooding enough to warrant this outlook.
Farther east, there is higher uncertainty in terms of flooding potential.
It`s unknown how far inland the heaviest precipitation will extend and for
how long. However, periods of heavy precipitation are possible here as well,
and given how much snowpack is in the mountains, an extended period of heavy
rain on snow would result in flooding of small creeks and streams as well
as significant rises on main stem rivers.
A flood potential outlook is issued when there is the potential for
significant rises or flooding along rivers and streams.
The exact scenario for flooding remains uncertain. This product will
be updated as necessary. Watches and warnings may be issued by the
National Weather Service if this situation worsens.
Since our weather outlook post yesterday the NWS has revised snow amounts upward. Forecast models are trending this storm with more moisture and more snowfall than originally thought. This storm still appears that it will mostly impact the higher mountain elevations with snowfall.
The current best guess for Klamath Falls snow is now 2-3 inches. There are winter storm warnings and watches in effect for some parts of Klamath County.
Snow should begin to impact the higher mountain elevations beginning around 7pm tonight.
The approaching storm should arrive in the local Klamath Falls area around 11pm tonight based on the latest estimates. Snow should fall overnight into Wednesday morning. Then, snow showers are possible Wednesday and should gradually taper off by Wednesday evening.
Above: Areas in pink are winter storm warning areas. Purple are winter weather advisory areas. Information current as of 1:30pm 2-19-19. For more details about the warnings and advisories please see the information below.
Above: Revised snow amounts trending upward as new forecast model runs show the approaching storm with more moisture than previously thought.
Pink Areas In Map Above: Winter Storm Warning issued February 19 at 12:52PM PST until February 20 at 10:00PM PST by NWS Medford
…WINTER STORM WARNING REMAINS IN EFFECT FROM 7 PM THIS EVENING TO 10 PM PST WEDNESDAY…
* WHAT… Heavy snow expected. Total snow accumulations of 7 to 14 inches expected with accumulations of up to 18 inches across the highest elevations. Between 1500 to 2000 feet, expect lower accumulations of 2 to 6 inches. Winds could gust as high as 35 mph over higher exposed terrain.
* WHERE… Heavy snow expected across the eastern Douglas County Foothills and South Central Oregon Cascades. This includes Highway 58, Highway 62, Highway 138, Highway 230, and the cities of Union Creek, Toketee Falls, Crescent Lake, as well as Diamond Lake and Crater Lake. Moderate snow amounts are expected near Steamboat.
* WHEN… From 7 PM this evening to 10 PM PST Wednesday. The heaviest snow will fall between 10 PM Tonight and 4 PM Wednesday.
* ADDITIONAL DETAILS… Travel could be very difficult with snow- covered roads. The hazardous conditions could impact morning or evening travel.
Tired of the snow yet? We aren’t either! A cold shortwave and frontal system is on the way to our local region. This one appears to be more of a high elevation snow maker for the east side of the Cascades and may drop some snow on the west side of the Cascades at lower elevations. A front will move through the region Tuesday night and Wednesday, with showers behind the front Wednesday evening.
