.SYNOPSIS...
A weak ridge building for mostly dry condition today. A
disturbance will cross the area on Wednesday, bringing
additional rounds of heavier snow in the mountains and rain in
the lowlands. Temperatures will cool later in the week through
the weekend with dry conditions.
&&
.SHORT TERM /TODAY THROUGH THURSDAY/...Current radar imagery
shows a bulk of precipitation largely exiting the southern half
of our region, while most of the area is dry this morning. An
upper level low spans farther away offshore with a weak
transient ridge building over western Washington. Conditions
look to be mostly dry today, with lingering chances of showers
over the mountains. Afternoon high temperatures in the mid 40s.
Northwesterly flow will develop on Wednesday with an
disturbance to the north that looks to sink down into the
region. Guidance shows most of the precipitation will be
confined to the northern portion of the CWA, along with the
mountains which should see some more accumulating snowfall. Snow
levels will originally start off around 1500 to 2000 early
Wednesday, gradually rising to 2500 to 3000 feet overnight and
into Thursday. With most of the precipitation being focused over
the northern portion of our area, the north Cascades could see
over a foot of snow, maybe two at Mount Baker. Lowland rain
showers will be possible at times on Wednesday and Thursday, but
generally chances are low across much of the interior. High
temperatures will warm and stay in the upper 40s and lower 50s
at this time.

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
Northwesterly flow continues over the region with mountain snow
continuing into Friday. Snow levels will remain around 2500 to 3000

flow. Temperatures will slightly cool, in the mid 40s.
