MOUNTAIN WEATHER FORECAST

Time and Day: 0900 Tuesday.

 

The Snapshot: I guess spring arrived during my absence.  Abundant sunshine and warm temperatures will grace the Cascade Mountains for the next few days.  Clouds move in with a chance of some light precipitation towards the end of the week.

 

The Science:  Building high pressure will produce clear and dry weather for the next few days.   The high pressure flattens and sags south towards the end of the week. This will allow some moisture (possibly snow) to make it to the mountains on Friday.

 

4-7day Long Range:  High pressure rebounds on Saturday for a dry and sunny weekend.

 

Precipitation: Water by 4am = 0 Snow = 0 24hr total inches of water ending at noon tomorrow = 0 24hr total inches of snow ending at noon tomorrow =  0   Trend and Timing: No precipitation expected until Friday.

Base Temp and Freezing levels:  Low: 24   High: 38 Freezing level: 3000’    5000’   Trends and Timing Freezing levels will rise to + 5000’ tonight.  Surface temperatures could push into the low 40’s with the aid of the sun today and tomorrow.

Winds (mph) Base:  0-5 WNW Ridge Top: 0-10 NW   Trend and Timing: Light NW flow at the surface with northerly flow aloft will continue through tomorrow.  Winds will shift more westerly as the week progresses.
