Time and Day: 0700
Monday
The Snapshot:
Mostly dry today with snow developing
overnight. Snow showers tomorrow with very active weather persisting through the
week.
The Science
Current Observations: It’s currently cloudy with 2” of fresh new snow to play
with today. The temperature is 29of, the barometer is at 1009mb and falling. Satellite radar has the main bulk of moisture
heading north with spotty showers in the central mountains. Weak east flow has developed with light easterly winds blowing.
The Forecast: Southerly flow aloft and weakening pressure gradients
will keep most of the moisture to the north of Stevens Pass today. A cold front will swing in late tonight for
snow showers and lower freezing levels. Cool unstable NW flow will keep snow showers persistent
through the middle of the week.
The Long Range: A strong frontal system arrives late
Wednesday with high winds, rising and falling freezing levels and heavy precipitation
finishing out the week. It is a bit far
out to get wrapped up in the details just yet, so stay tuned.
