MOUNTAIN WEATHER FORECAST

Time and Day:  0900 Friday

The Snapshot:   Clear (did you see that moon last night?) with warming through the weekend, snow for the second half of next week.

The Science:  The high-pressure cell parked over the British Columbia interior will continue to produce dry and clear weather for the PNW.  Warmer air flowing up the coast will begin to raise freezing levels to around 4000’ west of the crest while cooler air remains trapped in the eastern basin. (Temperature Inversion)

Long Range:  The pattern begins to change early next week as a series of systems begins to break through the high-pressure ridge.  With help from our friend east flow, the second half of next week could be snowy.  These storms are still far enough out for the models to disagree with the timing and amounts, so stay tuned as those details become more realistic.  

Precipitation ending at 4 am: Today’s 24hr Water = 0   Snow =  0 Tomorrow’s 24hr Water = 0  Snow = 0 Trend and Timing: No precipitation is expected through the weekend.

24hr temperature ending at 4 am tomorrow:  Low: 24   High: 34 Freezing level: +-4000.' Trends and Timing: Temperatures will continue to rise and fall around the freezing mark for the next few days.   Temperature inversions will be likely with freezing levels near 4500’ west of the crest.

24hr Winds (mph) ending at 4 am tomorrow: Base: 0-5 E Ridge Top: 0-10 E   Trend and Timing: Light east flow will continue through the weekend.
