NWS Forecaster Discussion




Area forecast discussion 
National Weather Service Spokane Washington 
1106 am PST Sat Dec 20 2014 


Synopsis... 
a more active weather pattern will continue into early next week. 
Another wet and robust weather system will bring snow to the 
mountains with mainly rain for the valleys today and tonight. 
Temperatures are expected to remain above average through early 
next week...before dropping down toward normal values by Christmas 
day. 






&& 


Discussion... 
morning update: messy forecast pattern. A warm front is draped 
across the region this morning and impulses riding along it will 
bring occasional rain and snow. Short-range guidance, such as the 
hrrr and hi-res NAM, have been showing one wave of precipitation 
pushing across the region from mid-morning to early afternoon, 
followed by brief break, before another broader wave of 
precipitation comes in from mid to later afternoon into this 
evening. That precipitation comes with the mid-level shortwave 
riding in on the nose of the jet stream, before things begin to 
dry out from the west overnight into Sunday morning so that by 
afternoon the main precipitation will be near the Cascades crest 
and over Idaho, particularly the central Panhandle mountains, 
through the Blue Mountains. 


Winter weather advisories remain in place for the Cascade 
mountains and valleys, with the most significant snows expected 
both near the crest and north of Lake Chelan. This is where some 
of the colder air remains, though even the most guidance that 
keeps snow levels lowest tends to bring them up a bit through this 
afternoon into tonight. Places like the Methow Valley, including 
areas near Twisp, have reported around 4 inches of snow so far and 
spots could pick up another 4 to 6 inches through this evening, 
with locally higher amounts in the higher terrain, before the 
rates start to wane as the drier air comes in overnight into 
Sunday morning. 


Winds are expected to increase with this system, especially 
overnight into Sunday when drier air and mixing comes with the 
mid-level disturbance riding that jet. Right now this is not 
prime timing for thinking any wind highlights will be needed. But 
it will be monitored. /J. Cote'

Aviation... 
18z tafs: periods of mainly rain expected around taf sites from 
mid morning to early afternoon and again from late afternoon into 
tonight, before precipitation starts to wane from the west 
overnight into Sunday. Look for MVFR/IFR conditions. Winds are 
expected to increase later this evening into Sunday. We will have 
to monitor for possible llws, if the atmosphere fails to mix 
effectively this evening into Sunday morning. /J. Cote'
