Wednesday, February 19, 2020, 0800

In memory of the Tunnel Creek Avalanche:    2/19

Current Observations:
24hr Precipitation:          0

The Forecast:  Another bluebird day with temperatures recovering near 30f.  This dry and mostly clear weather will continue through the end of the week.

The Science:  The ridge of high pressure parked over the PNW will continue to split or block any incoming moisture from making it to the mountains.  Southerly flow will slowly erode the cold air along the eastern slopes over the next 24+ hours. This will push freezing levels up, thus watch for +-5000’ freezing levels by Friday.
   
Long Range. The next chance of measurable snow will be late Saturday night into Sunday.
