Above: Klamath Falls could see up to 1″ of rain Saturday!
A strong low pressure system is already drifting our way from the south. It will cause the atmosphere in our local region to become significantly unstable Friday afternoon and overnight into Saturday. We have a classic thunderstorm pattern setting up for our region according to the NWS Medford. A very active thunderstorm pattern is expected Friday afternoon, overnight into Saturday.
Strong low pressure system for this time of the year will move north toward northern California and southern Oregon late Friday afternoon, then move through the area during the day Saturday. This will bring a chance of thunderstorms, some with strong winds, small hail, and heavy rain Friday eve/night, followed by widespread moderate to heavy rainfall west of the Cascades on Saturday. Showers and thunderstorms are also still possible east of the Cascades, along with strong, gusty winds outside of thunderstorms. Temperatures will also be 20-30 degrees cooler on Saturday.
Confidence is high for the heavy rain, gusty winds, and cooler temperatures; but some questions remain on whether this low pressure system will be able to produce scattered thunderstorms, especially late Friday afternoon and evening. The low will move northeast of the area Saturday night followed by a break in the weather Sunday. A weaker, yet still active weather pattern will continue early next week. It is worth noting that the rainfall reflected in the forecast is very significant for the end of May, and it will largely be beneficial for our area despite it not being enough to eliminate the drought. Some daily rainfall records may be broken on Saturday, especially for our climate stations west of the Cascades.
