Time and Day: 0715 Saturday
The Snapshot: Light rain and mostly cloudy today, clearing
and warmer on Sunday.
Current Observations: 2”
of very wet snow on the upper mountain this morning, with no accumulation in
the base area. It is lightly raining to the ridgetops now. Temperatures are
33-35 degrees across the mountain, RH is 100% and the barometer is slowly
rising.
The Science: A weak frontal passage last
night and this morning has brought continued mixed precipitation. The radar to
our west is clearing up rapidly this morning and the bulk of the moisture
should be done. Light rain showers in the wake of the front should end soon.
High pressure builds this afternoon and Sunday for very mild, dry, and warm
weather. Light east flow may create a bit of an inversion at the Pass on
Sunday.
The Long Range: A weak front in southerly flow will approach
Washington on Monday, with freezing levels a little higher than we’d like,
somewhere around 5-6,000’. It’s not a particularly strong feature and heavy
precip is not expected. The associated trough moves through on Tuesday with
slightly lowering snow levels.
