.SYNOPSIS...
More wet weather is on its way. The next storm system will bring
widespread rain and mountain snow late tonight into Friday,
followed by showery and breezy weather for Saturday. Several
inches of snow will be possible on Sherman, Stevens, and Loup Loup
Passes. Sunday looks dry. Unsettled weather returns Sunday night
into Monday and continues through next week, with several more
rounds of rain and mountain snow.

.DISCUSSION...
Issued a Winter Weather Advisory for snow in the Okanogan
Highlands for tonight through Friday morning. Surface
observations around the Republic area show low 30s with dew points
in the low 20s. This should result in wet bulb temperatures
dropping into the upper 20s as precip gets going late tonight for
this area. It may take a little bit of time before road
temperatures cool off enough before snow sticks, but with the
nighttime arrival of this weather system we should see roads
becoming snow covered by early Friday morning. Total snow
accumulations for the area will range between 2 to 4 inches. /SVH

.AVIATION...
06Z TAFS: An occluded front will move into the region tonight.
Expect clouds to thicken from the top down through this evening
with rain moving into KEAT after 06Z and into the Panhandle after
12Z. Rainfall will be light but steady for a 12 hour period over
much of the region. Cigs/Vis are expected to lower into MVFR
category through the morning on Friday with little improvement at
KGEG, KSFF, KCOE and KPUW for the afternoon. The front will clear
the western portion of the basin by mid afternoon Friday with
convective showers forming behind the front by late afternoon.
