NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
432 am PDT Sat Sep 20 2014 


Synopsis... 
strong high pressure will provide a generally clear...warm and 
dry weekend for the inland northwest. The new work week will start 
out with continued above normal temperatures...but a weak cold 
front will bring a chance of showers starting Tuesday. From mid- 
week Onward an approaching deep trough will increase the 
probability of rain with cooler temperatures. 


&& 


Discussion... 
today through Sunday night...a ridge of high pressure will build 
over the region, keeping dry conditions and warming temperatures 
over the inland northwest. Surface high pressure will shift to the 
east side of the Continental Divide, promoting northeast flow. 
This will bring dry Continental air into the region that will 
downslope into the Columbia Basin, drying it further. Mostly clear 
skies will promote daytime temperatures about 10 to 15 degrees 
above seasonal normals for the weekend. By Sunday night some 
monsoonal moisture may infiltrate the southeast zones but chances 
are it will bring only mid level clouds but no precipitation. 
/Kelch 


Mon through Wed night...with the breakdown of the upper ridge, 
we'll see a very weak wave move NE across the region Mon and Mon 
nt. Given the lack of deep instability over a dry sub- cloud 
layer, it is not expected to produce much more than some clouds 
for Mon nt. Confidence is not high that this short-wave will be 
dry though, mainly because model guidance shows a decent signal 
for the possibility of high- based convective pcpn Mon into tues 
morning first in the Cascades, then spreading NE. The European model (ecmwf) was by 
far the wettest with this feature compared to previous NAM and GFS 
runs. The latter models have trended slightly wetter, so this will 
need to be watched. A slow- moving cold front is expected to make 
landfall tues nt and Wed morning along the Pacific NW coast. We've 
been favoring a slower trend of this front as far as its ewd 
progression based on model trends and pattern recognition applied 
to the north-south shearing offshore trough. The downstream 
effects of this shearing will be a more meridional steering flow 
over ern WA and north Idaho, leading to a more persistent thermal 
ridge and warm, dry wx likely extending into Wed for most towns. 
Confidence is increasing that this stalled front will not make 
much eastward progress... likely not reaching the Idaho Panhandle. 
For now, we limited the bulk of the rain through Wed nt to the 
Cascades. We warmed temperatures for far ern WA and the Idaho 
Panhandle especially for Wed, with temps still around ten degrees 
above normal. Bz 


Thursday through saturday: a low off the coast of Washington and 
a strong trough along the West Coast will push southern moisture 
into the region. The models are having issues with the timing of 
the this system as they have continued to push this pattern 
further back from previous runs. Once the front pushes through the 
region, rain showers will impact most of the region and 
temperatures will return to season normals of around 70. An 
occasional thunderstorm is possible along the Panhandle of Idaho 
as the front pushes through the region on Friday. Temperatures 
will increase around 10 degrees on Saturday from the highs on 
Friday. /Jdc
