Mountain Weather Forecast

Time and Day: 0700 Saturday

The Snapshot: Partly cloudy and cooler with light snow today, dry and partly cloudy most of Sunday.

The Science: Friday’s cold front has passed, dropping 5” of snow. Westerly flow behind the front will maintain light snow showers Saturday before a brief high pressure ridge brings dryer and slightly warmer air to the PNW overnight Saturday and Sunday. The next front will approach Sunday afternoon. It looks to be quite stretched out and thus will not pack much of a punch, but should bring another round of moderate snow for Stevens Pass. March continues.

The Long Range: Active weather continues into next week with the pattern of trough/short-lived high pressure continuing. Freezing levels bounce around between 3,000-5,000 feet so stay tuned for rain vs. snow amounts.

24hr Precipitation ending at 4am: Today 24hr water = .25   snow = 1-3” Tomorrow’s 24hr water = .25-.5    snow = 2-4” Trend and Timing: Light snow flurries during the day Saturday, ending Saturday evening. Dry Sunday morning, light snow beginning Sunday afternoon.

24hr temperature ending at 4am:  Low: 25    High: 33 Freezing level: 3500-2500 Trend and Timing:    Typical midday warming will bump the air temperature up to near or just above 32. Freezing levels should remain well below pass level Saturday night and Sunday morning.

24hr Winds (mph) ending at 4am: Base: W 5-10 Ridge Top: WSW 10-20 Trend and Timing: Consistent light winds will taper off Saturday night.
