Area forecast discussion National Weather Service Spokane Washington 341 PM PST sun Nov 23 2014 Synopsis... the north Idaho mountains will continue to receive snow this evening, along with the Cascade crest near Stevens Pass. The breezy winds will taper off overnight, and Monday will be a relatively quiet and chilly day. More rain and heavy mountain snow is expected Monday night into Tuesday. A breezy and wet but warm Thanksgiving day will give way to a colder weather pattern for the Holiday weekend with the mountains receiving several rounds of snow. Snow levels will fall to valley floors by the weekend. && Discussion... tonight and monday: a temporary break in the wet weather can be expected starting tonight. A moist and progressive cold front will push south and east of Spokane and through north Idaho early this evening. Somewhat drier air will move into the region from the northwest, although enough residual moisture and favorable orographic flow will keep the threat of mountain showers. This is especially true along the Cascade crest near Stevens Pass where hints of a pscz may linger and then central Idaho Panhandle mountains. The only concern for accumulating valley snow would be north of Bonners Ferry, but the front will quickly exit this area and allow the threat of snow to taper off. Meanwhile, either the valley locations will be done with snow for the evening, or have warmed up and should just experience rain this evening especially across the central and southern Idaho Panhandle. Breezy winds will continue into the early evening behind the front with gusts to 30 mph. These winds will decrease overnight and become light by Monday as surface pressure gradients relax. Skies will clear for a good chunk of eastern Washington. This coupled with lighter winds, wet ground and radiational cooling will lead to rather chilly temperatures overnight into the 20s. These sub freezing lows and frozen ground will also raise the risk of icy roadways by early Monday morning for the commute. Meanwhile, boundary layer moisture remains high overnight especially across the Palouse and Spokane/Coeur D'Alene area. Given the southwest winds and light precipitation today, there is a good chance of seeing stratus and patchy fog develop late tonight into Monday morning. This threat will expand into the northern and Panhandle valleys as well. By Monday, the low cloud deck will gradually erode but daytime temperatures will be inhibited by the cloud cover. In addition, mid and high level clouds will be on the increase as the next weather system approaches. /Rfox. Monday night through Thursday morning...no major changes for the mid forecast time frame. High pressure will build in the eastern Pacific just off the coast. This will put the inland northwest in a northwest flow...before coming around to westerly Wednesday night. This flow will tap in deep Pacific moisture tap to move over the ridge and drop through the region through the period. We are looking at an extended wet and unsettled period through early Wednesday evening. * Precipitation: You Bet. Precipitable water by Tuesday morning will approach an inch which is around 270% of normal. Quite wet indeed. Isentropic up-Glide will get established over pac northwest early Tuesday evening and remain in place through Wednesday afternoon. A pretty substantial rain shadow will develop in the Lee of the Cascades keeping the lower east slopes and the deep basin from getting much more than a few hundredths to maybe a tenth of an inch. Outside of the basin the lower elevations and northern mountains look to get from .25 to .55 if not slightly more. The Panhandle mountains from .50 to .80 and the higher elevation of the Cascades from .50 to well over an inch near the crest. * Snow: a much trickier questions. Southerly surface winds and strong warm advection is what will cause the lifting processes to squeeze out all the moisture. But this will also raise snow levels rapidly Tuesday night. For all of the urban areas snow levels will be high enough for precipitation as all rain. The tricky parts will be the mountain valleys. By the time the heaviest precipitation gets into these areas the snow should turn to rain. At this time snow accumulations for all of the mountain valleys remain below highlight criteria. An even trickier snow forecast will be for northeast Washington and Idaho Panhandle mountains above 3-4k feet where the same processes will be at work, but it will take a little longer to warm. 24 hour snow amounts will range from 6-9 inches which would be the low end of an advisory. I will hold off on any highlights...first because we already have advisories out for the central Panhandle mountains and second there is still a little uncertainty on just how fast temperatures will increase. * Temperatures and wind: as mentioned above there will be strong warm air advection and breezy/gusty south-southwest winds. Temperatures on Tuesday will increase with high from the mid 30s across the north to the high 40s/lower 50s across the south. Then add 4-5 more degrees for Wednesday putting highs well into the 40s and 50s. South-southwest of 10-25 mph with gusts 25-35 mph will be common across the region. /Tobin Thanksgiving day through Sunday...another day, another fight between medium range models. Why can't we just get along? The 00z run of the European model (ecmwf) was showing an Arctic front dropping south across the forecast area Thanksgiving day, leading to a much colder forecast than the more consistent GFS. Surprise...the 12z ec is much closer to the GFS solution. There are still differences in several of the details but the general consensus is for warmer temperatures in southerly flow at least through Turkey day. The stream of shortwave energy riding over the forecast area will bring some precipitation to the higher elevations of the inland northwest but valley precip is one of those pesky details that model are having a hard time deciding on, depending on the location of the upper jet and associated areas of enhanced lift. This jet will be directing a fetch of deep moisture into the region with pwats approaching 200 percent of normal. At least there is agreement on liquid precip as snow levels will be quite high. Breezy southerly winds will keep the atmosphere somewhat mixed overnight, keeping low temperatures at or above freezing for most of the valleys. The exceptions will be across the extreme northern valleys where winds will start to shift to the north and colder, drier air will infiltrate the valleys. For Friday and into the weekend, models start to fight again. The general trend will be a cooldown as an Arctic front slides south but timing and southern extent of the very cold air is still being debated. /Kelch && Aviation... 00z tafs: radar and satellite trends show the band of precipitation associated with a surface front moving southeast at a good clip. This will affect the kpuw/klws taf sites for the next couple of hours before exiting to the south. Also of note is a strong convergence band of precip just to the south of keat. A weaker band may bring brief MVFR conditions to keat through 02z. Dry/downslope advection from the west/northwest this evening should disperse stratus in the evening, but fog and low stratus will crop up toward Monday morning from kpuw to kgeg and ksff. The next weather system will approach the keat area after 00z Tuesday. /Ek && Preliminary point temps/pops...
