Time and Day: 0630 Wednesday
The Snapshot:
It’s a bit windy this morning with 40pmh gusts recorded at Tye Mill. Winds will diminish along with the snow
showers today. A sporty storm with wind,
rain and snow will grace the mountains to end the week.
The Science: A
high pressure ridge building in behind last night’s little storm will bring an
end to the snow this morning. This
morning’s radar still has some showers lifting north; so expect some snow showers
to continue this morning with sun breaks later today.
A strong, complex frontal
system developing off of the Oregon coast will bring rising freezing levels and
a good dose of moisture to the Cascade Mountains starting early tomorrow morning
and lasting into Friday. Models are
struggling with the temperature profile as well as the timing. So, at this point, we should expect snow
beginning early tomorrow morning (+-2am) changing to rain below +-5000’ and
then back to snow early Friday morning.
Those details will be refined later today.
The Long Range: The
weekend is trending mostly dry with more storms expected next week.

Precipitation Ending at 4am:
Today 24hr water = .25 - .5 Snow = 3-5
Tomorrow’s 24hr water = .5-.75 snow = 2-6
Trend and Timing:
Snow begins after midnight and
intensifies through the morning. The
mixed rain game should begin around noon or so. The precipitation will likely diminish
tomorrow evening and ramp back up on Friday.
