Area Forecast Discussion
National Weather Service Spokane WA
258 AM PDT Tue Oct 11 2016

.SYNOPSIS...
Today and Wednesday will be mainly clear and cool. Widespread
freezing temperatures are expected on Wednesday morning. Clouds
will be on the increase Wednesday night, and precipitation will
spread over the Inland Northwest on Thursday. A cloudy, wet, and
breezy weather pattern is expected Friday through the weekend.

&&

.DISCUSSION...

...WIDESPREAD FREEZE EXPECTED WEDNESDAY MORNING...

Today and Tonight: Cool and dry air will continue to seep into the
Inland Northwest today. Canadian high pressure moving down the
spine of the northern Rockies will produce northerly winds in the
5 to 15 mph range through early this afternoon. By this evening
our surface pressure gradients will become weak and winds will be
light through the night. The combination of dry air, minimal
clouds, and light winds will promote efficient radiational
cooling. Look for the coolest low temperatures of the season so
far with upper 20s and low 30s common throughout eastern
Washington and north Idaho. The Wenatchee, Chelan, and Lewiston
areas may escape a hard freeze, but Spokane, Moses Lake,
Ritzville, and Omak will have a good shot of a killing freeze. A
Freeze Warning has been issued for the Moses Lake and Ephrata
areas since they are climatologically within their growing season
for a few more days. Spokane, Ritzville, and Omak have past their
locally defined growing season so a Freeze Warning has not been
issued for these zones at this time.

Wednesday: Bright sunshine should warm temperatures into the 50s
on Wednesday. A chilly start to the morning and light winds (poor
mixing) through the day may inhibit warming. Enjoy the sun on
Wednesday. The upcoming wet and unsettled pattern will feature a
good deal of cloudy and gloomy skies.

Thursday: The models have struggled to pin down the timing of the
onset of precipitation in the Thursday/Friday time frame. The
evening runs of the NAM, GFS, and ECMWF have come into decent
agreement spreading rain over central Washington Thursday morning
and into eastern Washington and north Idaho Thursday afternoon and
evening. The track of a deep surface low along the coast Thursday
afternoon/evening suggests that cool air will be wedged along the
north Cascades. Snow levels as low as 3000 feet will be possible
Thursday morning around Mazama. Accumulations should remain above
the valleys, but a few inches of wet snow will be a good bet for
elevations above 3000-4000 feet on Thursday before precipitation
changes to rain Thursday night into Friday. /GKoch

Friday through Monday: Active wet unsettled weather interval
continues on through Sunday as a parade of weather systems with
well maintained moisture feeds pass through Eastern Washington and
Northern Idaho. The general longwave trof in the region allows for
these storm systems to have warm trajectories of approach
(southerly component) which keep snow levels rather high
(generally above 6000 feet MSL). Rainfall brought about by these
passing weather systems has the potential to be moderate to heavy
at times along with some intervals marked by breezy/gusty wind.
Shortwave ridging Monday is expected to interrupt the parade of
storm systems somewhat and allow for decreased pops, cloud cover,
and wind but could likely bring about overnight and early morning
fog and low clouds. Forecast overnight low temperatures should be
above normal given such an active wet weather pattern and for the
same reasons the daytime high forecast temps are near or slightly
below normal. /Pelatti

&&

.AVIATION...
06Z TAFS: A shortwave trough of lower pressure will dive south
across the region out of BC. A northerly pressure gradient will
tighten tonight with breezy winds funneling out of the Okanogan
Vally and through the Purcell Trench. Expect sustained winds of
9-13 kts at KMWH and KCOE. Precipitation associated with this
wave will be over the Panhandle and is expected to remain east of
KCOE. Winds will bring drier air into the region with cigs
expected to remain above 4 kft at TAF sites. Clouds will decrease
on Tuesday with mostly sunny skies and VFR conditions. /SVH
