&&

.DISCUSSION...
Tonight: As the front slides further East and drier air moves in
overnight lingering showers will mainly be for the Cascade crest and
ID Panhandle. The drier air will lead to colder lows, with frost
possible for the Republic area.

Saturday and Sunday: A ridge begins to build along the coast for the
start of the period and turn the West-East flow pattern into a
Northwest-Southeast pattern. A quick moving shortwave passes
through the region bringing a round of rain showers for the
Cascades, northern mountains, and ID Panhandle. Afternoon winds
expected to be breezy again as 850MB winds across the Basin
expected to be around 35 kts. The surface winds expected to be
gusty around 20 to 25 MPH. A dry, cooling trend is expected to
grip the region overnight and bring cooler temps to region with
widespread mid 30s. The cooler temps and moisture near surface
could bring more frost the Northern areas and into portions of
the Columbia Basin and Central ID Panhandle. As the ridge
continues to build on Sunday, the region dries out and the any
remaining showers dissipate by early Sunday. After a dry and
light wind day, the radiational cooling overnight is expected to
bring another round of frost and potential fog for the region. The
frost chances will continue to be in the Northern valleys and
sunlight sheltered areas for the Northern portion of the Columbia
Basin. Fog is expected to be in the North ID Panhandle. Highs for
the period will be generally in the 60s. Overnight lows will be
in the 30s to low 40s. /JDC

Monday through Friday: Models are in general agreement that a
strong upper level ridge will over the Western US on Monday and
stay parked over the area through the end of the week. This will
transitioning the weather pattern over the Pacific Northwest from
a cool and wet pattern to a warm and dry one. Temperatures will
trend warmer as the week progresses with highs reaching the upper
70s to low 80s by Friday. These highs are around 10 degrees above
normal, as average high temperatures for the Inland NW for this
time of year are around the upper 60s/low 70s. Clear skies and
light winds will allow for significant radiational cooling
overnight, keeping mornings relatively chilly. Low temperatures
will drop into the 40s, with locations such as Republic, Deer
Park, and Priest Lake dipping into the 30s. Frost and fog may also
be possible in these cooler locations. VMT
