Time and Day: 0700 Tuesday
The Snapshot:
Snow showers, gusty winds and cooler temperatures
today. It could be a nice powder day tomorrow. Another
warm moist air mass moves in on Thursday for a chance of rain heading into the
weekend.
The Science
Current Observations: 1.4”
of rain fell yesterday with 2" of snow overnight. It is partly cloudy this morning; the temperature
profile is 29/base and 25/top. The
barometer has clicked up a few notches to 1011mb’s. The winds are westerly and a bit gusty (+-10 mph)
on the upper mountain. The radar has cooler westerly flow filling in behind the
cold front that passed east of the crest just after midnight last night.
The Forecast: The Puget Sound Convergence Zone will kick in
today with heavy to moderate snow and falling temperatures. Snow slowly diminishes tomorrow with rising
freezing levels beginning on Thursday.
The Long Range:
Another strong warm front lifts up
through the region on Thursday with high freezing levels and another shot of
rain to wrap up the week. The models are
all over the board for what the weekend will bring, so we will have to wait to
see how that decides to play out.
24hr values daily 4am to 4am.
