Area Forecast Discussion
National Weather Service Spokane WA
910 PM PDT WED AUG 27 2014

.SYNOPSIS...
Dry and warm conditions are expected through the workweek. The
next storm system will arrive during the upcoming holiday weekend.
This will result in breezy to windy conditions along with an
increased chance for showers along with temperatures dropping
below normal.

.DISCUSSION...
Update: Satellite and radar from this evening showed an upper
level trough passing through Central British Columbia...with
elevated instability over southern British Columbia generating a
couple areas of thunderstorms. One storm made it close to the area
just north of Oroville and Chesaw. As tonight progresses the upper
trough in BC slides southeast with a small increase in mid level
moisture over extreme NE Washington and the North Idaho Panhandle.
This combined with mid level instability will likely lead to mid
level cumulus that may develop into weak cells around places like
Metaline Falls, Porthill, and Bonners Ferry. The NAM model was
capturing this the best showing a brief window between 3 and 6 am
where this could occur.  However with models showing minimal lift
current thinking is that these cells are more likely to remain
just north of the Canadian border. Sky cover was increased to
partly cloudy and POP`s were adjusted up slightly to near 10% in
these areas.  JW

.AVIATION...
06Z TAFS: A weak weather disturbance will clip the area on
Thursday. VFR conditions are expected over the aviation area
through 06Z Friday. Locally gusty winds will develop Thursday
afternoon along with isolated showers over the mountains near the
Canadian border. A stray thunderstorm can also not be completely
ruled out.  JW
