The winter snowpack is going quickly now at low elevations. The snow at the Airport observing site is down to 10 inch depth and is increasingly patchy. Over the past 20 years, once the snow depth is down to 10 inches at the airport, it takes 4 or 5 days on average to melt out. Here on Keystone Ridge, it's a different story. There has been no loss of snow cover at all except right around the house. Here's a photo of the weather station from Thursday morning.
The forecast is for a substantial warm-up starting Friday, with highs in the 50s at valley level for the foreseeable future, and night time lows near freezing here on the ridge. This will chew up the snow in a hurry.
