Area forecast discussion National Weather Service Spokane Washington 1013 am PST Tuesday Dec 1 2015 Synopsis... low clouds with occasional flurries will be common in valleys with a mix of sun and clouds in the mountains. A weak frontal system will bring a wintry mix Tuesday night into Wednesday...with an even wetter system moving in Wednesday afternoon into early Thursday. The combination of the two weather systems will likely produce light to moderate snow near the Cascades and over the northern Washington mountains. There will also be a threat of freezing rain across western portions of the Columbia Basin, Wenatchee valley and Okanogan Valley. Wet but warmer weather is expected from Thursday afternoon and into the weekend. && Discussion... morning update: the forecast is generally on track. A weak mid- level disturbance near the Washington/Idaho border will continue to shift east through the rest of the day. This will bring the best flurry/isolated snow shower eastward, but I still kept some isolated flurries in the forecast. The next system is still on track to come in later tonight into Wednesday morning with a wintry mix. It looks like quick mover though, with the best threat waning after about 16-18z Wednesday. /J. Cote' && Aviation... 18z tafs: a weak mid-level disturbance exits thru Idaho this morning, taking the main flurry/isolated snow shower threat with it. Expect MVFR/VFR conditions over eastern taf sites and IFR conditions over the west (mwh/eat) but some brief improvement is possible this evening. The next system enters late this evening and overnight, before exiting through Wednesday. This will bring a threat of -fzra/snow around eat/mwh, especially toward 07-09z continuing through 13-14z. After 10-12z the orecip threat expands toward the eastern taf sites. Geg to Coe is expected to see mainly snow, but there may be some freezing rain mixed in on the tail end around 16-18z. Puw/lws is expected to see a mix of freezing rain/snow durign this time frame too. Light icing is possible in any locations that see freezing rain, but the speed of the system should keep any ice amounts less than 0.05 inches. /J. Cote' && Preliminary point temps/pops...
