NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
1003 PM PST Thursday Nov 27 2014 


Synopsis... 
a rainy and breezy weather pattern will envelope the region 
going into Friday, but snow levels will remain above pass levels 
for motorists traveling on Friday. The arrival of a very cold and 
windy Arctic front Friday night into Saturday will bring winter 
driving conditions to the mountain passes and much cooler weather 
for the weekend. Cold conditions, with a few minor snow bearing 
weather disturbances, is forecast for new work week. 




&& 


Discussion... 
evening update: adjustments made based on newest model runs and 
satellite/radar trends. I cut back pops for the remainder of the 
night, especially from the Spokane area westward. I also reduced 
pops for this evening south toward the Palouse/l-c valley, but 
they still rise overnight into Friday. On Friday itself I also cut 
back pop some in the morning across the Spokane area westward, but 
ramp them up more Spokane afternoon and evening, making some 
upward adjustments in precipitation amounts. Friday's system is 
still on track to bring colder air in and models turn off the 
precipitation threat relatively quick from the northwest as that 
colder air is coming in. Adjustments were also made to overnight 
lows, bumping them up a degree or two given current trends. 


It still looks like there is some snow threat on the tail end of 
the friday's system. The chances appear best late Friday 
afternoon and evening near the Cascades and Friday night into 
Saturday morning farther east. This may include the eastern third 
of Washington and north Idaho. Given the winds with the system, confidence 
leans toward favoring little significant accumulations over 
northeast Washington and north Idaho. However some light to moderate 
accumulations are possible near the Cascade crest and late Friday 
night and moreso toward Saturday morning toward the central 
Panhandle mountain passes. There may be some light accumulation 
lingering through Saturday morning over the southeast WA, across 
the higher Palouse of Washington and Idaho and The Blues through Camas 
Prairie, in the favorable northwest flow. 


The main thing to get: there may be some impacts over the passes, 
first in the Cascades late Friday afternoon/evening and 
potentially toward the central Panhandle toward late Friday night 
into Saturday morning. The Palouse southward will have a secondary 
but minor threat. /J. Cote' 


&& 


Aviation... 
06z tafs: a developing storm system will bring mean increasing 
clouds and rain chances over the next 24 hours. The best chances 
will start late tonight into Friday morning around puw/lws. 
Chances will also come toward the geg to Coe areas by Friday 
morning, but the better threat here will be in afternoon and 
evening. Look for VFR conditions, with local MVFR/IFR cigs 
possible in heavier precipitation as Friday afternoon progresses 
into evening. The lowest precipitation threat will be over the Lee 
of the Cascades and deeper Columbia Basin, including eat/mwh. 
There is some potential for fog and stratus to develop overnight 
and early Friday around eat, but latest forecasts guidance 
suggests it may not be as deep if it develops at all. In the messy 
pattern, there will also be breezy and gusty winds, but these may 
be decoupled tonight and early Friday leading to areas of low level wind shear. By 
mid to late morning/afternoon the atmosphere begins to mixed again 
and gradients will tighten with the incoming low, leading to 
breezy conditions. Some winds gusts between 30 and 45 kts will be 
possible in the afternoon, especially over the expose taf sites 
including geg. 


Note: the visible sensor at eat is out of service so amendments to 
visible are not scheduled. The offending sensor replacement is on 
order and may be returned to service by Saturday. /J. Cote'
