Time and Day: 0630
Friday
The Snapshot:
Windy
with persistent snow showers
today, dry tomorrow, heavy snow on Sunday.
Warming next week.
The Science
Current Observations: This morning’s radar has some nice snow showers in the
convergence zone, telemetry is reading 7” of new snow with the temperature at 290f , the barometer has bummed up
to 1006mb, the winds are blowing 5-10mph and out of the west.
A weak convergence zone
with cool unstable WNW flow will keep light to moderate snow falling into
tomorrow morning.
Tomorrow, a high pressure
ridge, moving into the inland NW (NE Oregon/Idaho), will begin to push the moisture
to the north for a temporary break in the
precipitation.
SUNDAY. Sunday is looking very interesting with a
potential heavy snow event. A strong
warm front, with a good punch of moisture, will enter the Cascade Mountains
early Sunday morning. A cold front, hot on
its heels,
will swing in with good cool air mixing.
At the moment freezing levels look to peak around 4500’ then fall to
3500’ late Sunday. Models have yet to align with specifics details, so stay tuned.
The Long Range:
Snow/rain tapers off on Monday
with holiday period looking warm and rainy.
