AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SPOKANE WA
248 PM PDT Tue Oct 2 2012

.SYNOPSIS...
A strong cold front will bring breezy to locally windy conditions
through this evening then decreasing overnight into Wednesday. These
gusty north winds will result in areas of blowing dust for central
Washington and heighten the fire danger for much of the Inland
Northwest. The second half of the week will be cooler than
average. Some parts of northeast Washington and north Idaho may
experience a hard freeze by early Thursday morning. The dry and
cool weather will continue into the weekend.

&&

.DISCUSSION...

...Gusty winds through this evening will bring areas of blowing
dust and elevated fire danger...

Tonight: As of 2 PM, the surface cold front descending from the
north extended from Bonners Ferry to Chewelah to Ephrata. Abrupt
wind shifts to the north were experienced at weather observing
stations between 1 PM and 2 PM near these communities. A surface
pressure gradient exceeding 7mb was observed at 2 PM between
Spokane and Omak. By 5 PM, the majority of eastern Washington and
the north Idaho Panhandle will have a transition to north of
northwest winds. As mentioned in previous discussions, the
north/south pressure gradient perpendicular to the Okanogan Valley
will serve to accelerate winds through early evening around Omak,
Oroville and Tonasket. Wind exiting the Okanogan Valley onto the
Waterville Plateau will buffet the communities of Mansfield,
Waterville and the Banks Lake area. Gusts of 45 mph will be
possible through 8 PM during the peak surface gradient and
strongest low level cold advection. Web cameras and the latest
visible satellite imagery suggests that dust has begun to blow on
the Waterville Plateau. We will keep close tabs on the impacts of
the blowing dust. For the time being, a Wind Advisory is in effect
for the Okanogan Valley and Waterville Plateau until 8 PM.

The cool Canadian air mass will bring a shot of dry surface
dewpoints to the region that we have not seen in months. Despite
the falling temperatures this afternoon and evening behind the
cold front, relative humidity levels will continue to drop into
the early evening hours. The combination of gusty winds and low
humidity levels prompted the issuance of a Red Flag Warning for
the heightened potential for rapid wildfire growth over a large
portion of central and eastern Washington as well as north Idaho.

Wednesday and Wednesday Night: Temperatures on Wednesday will only
top out in the upper 50s to mid 60s. We haven't experienced chilly
temperatures like these since early June. North or northeast winds
of 10 to 15 mph will make it feel like "jacket weather". Humidity
levels will continue to be extraordinarily low for as cool as the
air mass will be. Wind and low humidity levels may produce border-
line Red Flag conditions from Sandpoint to Spokane to the Upper
Columbia Basin Wednesday afternoon. As the pressure gradients
relax Wednesday night, many places will drop to the coolest
temperatures of the season so far. Some gardens that have yet to
experience a frost or freeze will fall below 32 degrees around
Spokane, the West Plains and Upper Columbia Basin early Thursday
morning. /GKoch

Thursday through Saturday night...The 12z runs of the GFS and
ECMWF models are in good agreement of the continuation of a rex
block pattern during this period...with a blocking high centered
along 140W off Vancouver Island with a closed low underneath this
high off the Northern California coast. This will result in
northerly flow over the Inland Northwest with the high slowly
moving east towards the British Columbia coast. There is one wave
that moves down in the northerly flow Thursday morning over North
Idaho but with the very dry low level atmosphere and a stable
atmosphere nothing more than mid and high level clouds is
expected. Very dry conditions in the lower levels with dew points
mainly in the teens will result in strong radiational cooling at
night with freezing temperatures across several valley areas.
Wenatchee and Lewiston however should stay above freezing.
High temperatures will start off about 3-6 degrees below normal
Thursday and Friday before moderating over the weekend as the air
mass begins to warm as the high moves closer to the area. JW

Sunday through Tuesday: The Rex Block pattern will continue to
dominate the weather across the Inland Northwest into early next
week. The flow pattern will remain out of the north and northeast
over the region, resulting in continued dry conditions. Models
show a very weak shortwave diving south out of Canada around the
Monday/Monday night time frame. This may give us a little breeze,
but probably will only spread some high clouds across the east
portions of the forecast area. For the most part, the region will
be dominated by high pressure with clear to mostly clear skies.
High temperatures will run about 5 to 10 degrees above seasonal
averages in the upper 60s to lower 70s for much of the valley
locations. Low temperatures will be cool due to the low dew point
temperatures and clear skies across the region overnight, but
should be close to seasonal average. Models show dew point
temperatures increasing through the period, so I ticked up our
lows a degree or two on average each night. /SVH

&&

.AVIATION...
18Z TAFS...A strong cold front coming out of British Columbia will
result in gusty north-northwest winds at the TAF sites mainly during
the 21z Tuesday - 04z Wednesday time frame.  As of 18z the front was
near the Canadian Border and slowly moving south.  Model soundings
suggest potential wind gusts in the 30-40 knot range with the
strongest winds channeling down the Okanogan Valley into the Moses
Lake area.  KEAT is a lower confidence forecast put given strength
of front believe that a gusty northeast winds will surface behind
the front around 01z.  The winds will kick up blowing dust lowering
surface visibilities to around 5-6 miles.  JW
