.SYNOPSIS...
Dry, cool conditions expected through Thursday. Temperatures
will then increase slightly through the end of the week. The
weekend brings chances of unsettled weather and precipitation
including snow in the mountains. Cooler, wetter conditions
expected for start of next week.

&&

.DISCUSSION...
Tonight through Sunday: A low is slowly creeping south along
the coast. It is expected to stall off the southern Oregon coast
for Thursday and Friday. It will send weak waves of moisture
into the Pacific Northwest. Ensemble agreement is decent for the
placement and track of the Low. Best chances for any precip are
along the Cascades and Okanogan Foothills but amounts not
expected to be more than a few hundredths of an inch for
Thursday. The Low finally pushes on shore Friday and showers
chances spread across the entire Inland Northwest. The Low will
usher in colder air and lower snow levels. Elevations above
4000ft can expect some snow mixed with rain for the weekend.
Snow amounts expected to be less than 2 inches. Ground might be
too warm for any decent surface accumulation. Rain amounts for
the lower terrains will range from up to a tenth for the Central
Basin and Okanogan Valley, 0.2-0.5" for most valleys and
Eastern Basin, and around 0.75" for higher terrain of Idaho
Panhandle. Highs will drop into the 50s for the period.
Overnight lows will range from the upper 20s to 30s. The region
can expect an increasing area of frost and freeze. Might want to
consider harvesting any remaining produce from backyard
gardens.

Monday through Wednesday: Ensembles are keeping the Low over
the region for Monday. Showers chances continue through Monday.
By Tuesday, the Low digs further south. It will start a drying
trend for the region. Temperatures continue to be on the cooler
side of the Low. Highs continue to be to in the 50s. Lows will
stay in the upper 20s and 30s. /JDC
