.SYNOPSIS...
High pressure over the region will bring warm and dry
conditions through the work week. Unsettled weather returns this
weekend with breezy winds and a chance of mainly mountain
showers.
&&
.DISCUSSION...
Today and Saturday: The region continues to be under the
influence of a weakening ridge for the next couple of days. It
will bring unseasonably warm temperatures into the 80s and low
90s. Overnight lows will chill into the 50s. Increasing upper
level clouds are expected for the next couple days as monsoonal
moisture slides into the Pacific Northwest from the South.
Sunday: Ensembles continue to swing a cold front through the
Pacific and Inland Northwest. There are increasing precip
chances with the front with the best chances over the Cascades
and Idaho Panhandle. Amounts are not expected to be of any
significance. The westerly flow will keep most of the Basin in
the rain shadow. Winds will be increasing across the Basin with
frontal passage. They will be sustained in the teens with gusts
into the 30 to 40 mph range. With winter wheat in the process
of being planted, blowing dust will be something to look out for
across portions of Central and Eastern WA. As far as
temperatures, Sunday will be cooler with high temperatures only
rising into the upper 60s to mid 70s, and dry air moving in
behind the cold front will allow overnight lows to get quite
chilly as well Sunday night into Monday. For some of the
region`s colder spots including Republic, Deer Park, Colville,
and Winthrop, lows will likely fall into the 30s for the first
time this season.
Monday through Wednesday: A ridge is expected to begin to build
in behind the front. It will bring another round of rather warm
temperatures through much of next week. Highs will rise into
the low 80s again by Tuesday and Wednesday, around 10 degrees
above normal for late September. Overnight lows will climb back
into the 40s and 50s. /JDC
