MOUNTAIN WEATHER FORECAST

Time and Day:  0900 Monday

The Snapshot:  One could say that the mountains are a bit soggy this morning.  The rain showers will linger in the mountains today and then slowly diminish over the next 24-36hrs.  Wednesday may be the nicest day of the week with more of rain expected on Thursday.  

The Science:  Unstable onshore flow, leftover from the weekend’s PNW Typhoon, will keep rain showers persisting through tomorrow.  A weak upper-level ridge will begin to break up the showers and allow some clearing to develop over the next few days.  This will also allow some cooler air to settle in with early morning temperatures dropping below freezing.       

The Long Range:   A warm front will bring more rain and rising freezing levels on Thursday.   The weekend appears to be dry with high pressure building off the west coast. 

Precipitation Ending at 4am:

Today 24hr water = .25  Snow =  trace

Tomorrow’s 24hr water = .10 snow = trace
