Special Weather Outlook: Thunderstorm activity expected from Monday afternoon until Wednesday. This will be followed by a new period of hot weather into next weekend. Some storms could become strong. Thunderstorms may continue well into the evening hours.

An upper level low off the coast of California will bring an active weather pattern for the start of the work week.  First on Monday, storms are expected to form east of the Cascades in the afternoon and evening. A red flag warning has been issued for the expected storm activity on Monday covering roughly the red area in the graphic below. There is a slight  chance of storms Monday night east of the Cascades. Confidence in overnight storm activity is low as instability is lacking. With more moisture to work with on Tuesday and high pressure backing off, we should see more storm activity across the region. Locally stronger storms and winds are possible in the red areas on Tuesday.  A fire weather watch has been issued because of the potential storm development on Tuesday covering roughly the red area in the graphic below.

Note: Lighter shade of red is where isolated storm coverage is expected, darker red is where scattered storm coverage expected.

A Red Flag Warning does not mean there is a fire. It means that
critical fire weather conditions are either occurring now or will
shortly. These conditions promote rapid spread of fire which may
become life threatening. Evacuate if ordered to, or if a fire
threatens.

If you have not packed your evacuation kit yet, now is the time to
do so. This includes items like important documents and essentials
you cannot live without. Fill your vehicle’s fuel tank. Visit
ready.gov/kit for more information.

Plan now to avoid using equipment that could cause sparks during
the period when critical weather conditions are possible. Visit
weather.gov/medford/wildfire for links to fire restrictions in
your area.

A Fire Weather Watch means that critical fire weather conditions
are possible during the valid watch time. These conditions could
promote the rapid spread of wildfires which could become life-
threatening. Check weather.gov/medford for forecast updates and a
possible upgrade of the this watch to a Red Flag Warning.
