  (on/off)  Help NOTE: mouseover dotted underlined text for definitionFxus66 kotx 222346 afdotx area forecast discussion national weather service spokane wa 346 pm pst Fri feb 22 2019 Synopsis More light to moderate snow will be likely late this afternoon and this evening as a storm system moves quickly across eastern washington and the idaho panhandle. A moist frontal system is expected to stall over oregon and central idaho Saturday night Sunday before moving back to the north Sunday night and Monday. This will have the potential to produce moderate to heavy snow as far north as highway 2. Temperatures will remain on the cool side of normal the next 6 to ten days with mountain snow at times. Discussion Tonight through Saturday night... A fast moving frontal system is moving through the region this afternoon and will be out of the area by early Saturday morning. Light snow began this morning as a warm front moved through. Snow accumulations were very light south of highway 2 and 1 to 2 inches up into the northern zones from republic to sherman pass to metaline falls. More snow is expected this evening and overnight as the accompanying cold front moves through the region. Widespread accumulations of around an inch and locally to around 2 inches will be possible with the front. The cascade crest will see 2-4 inches. Slightly heavier snow is expected for the idaho panhandle, the camas prairie and the blue mountains as the flow becomes westerly with the front. The idaho panhandle should see anywhere from 3-5 inches and locally around 6 inches, the blues and camas prairie 2-3 inches and locally around 4 inches. An area of concern will be east of a line along highway 195 where 1-3 inches of snow will be possible around coeur d'alene, moscow and near pullman by morning. This would satisfy a winter weather advisory and one will be issued through early Saturday morning. The front pushes east between 6-12z tonight bringing a quick end to the snow. The atmosphere will destabilize behind the front on Saturday and with several weak waves moving through the region there will be a chance of snow showers through Saturday evening, mainly for the cascade crest and near the id mt border. Additional accumulations should be light. Temperatures will remain on the cool side of normal with lows tonight in the teens and low 20s and high on Saturday in the upper 20s. Tobin Winter storm expected Sunday night through Monday across southern wa and the central id panhandle... Sunday and Monday: unsettled weather is expected as a trough moves across the pac nw. Models show a surface low moving across the region. Current models differ a bit on location, but it looks to be around northern oregon... Maybe moving into portions of southeast wa and the southern id panhandle. This low is fairly strong and is not expected to weaken significantly as it moves east. Have made some changes to the forecast... Mainly to chance of precipitation and snow amounts. Portions of NE wa and the north id panhandle will see little to no snow. The best chance of snow will be across the palouse and east and south into southern shoshone county, the lc valley and camas prairie as well as parts of central wa. Snow accumulations would be fairly light Sunday, an inch or less. The 2 spots that will likely see 2-3 inches would be the blue mountains and the camas prairie. Then Sunday night into Monday as the surface low begins to influence us more, we will see more widespread snow move into the region. Sunday night the snow would be across the southern portions of our forecast area, and then just in time for the Monday morning commute the snow will move northward towards wenatchee, moses lake, spokane, coe. Snow will continue to fall through the afternoon and then begin to push south and east |
through the evening and overnight hours. The northern counties... Okanogan, ferry, stevens, pend oreille, bonner and boundary is likely to light snow accumulations. Meanwhile all counties to the south of that will see light to locally heavy amounts of snow... Depending on where you are. The heaviest snow looks to fall across the blue mountains and to the north and east towards lookout pass. Pullman, lewiston, the camas prairie will likely need highlights. Given the easterly flow into the cascades, locations west of moses lake into the waterville plateau, wenatchee and plain area will see several inches of snow as well. One forecast uncertainty is how much will the spokane area see. The aftn forecast agrees pretty well with wpc that we will see about 2 inches. Sunday night as the energy begins to shear and move north snow will generally come to an end for most areas. The one exception will be southeast wa and the central id panhandle where they could pick up an additional few inches. Tuesday and Wednesday: the trough remains off the pac NW coast and we get a weak ridge that bumps up into our area. Still have mention of some snow across the region. It looks like northern wa and id has the smallest chance of accumulating snow. The models are showing a wave moving under the trough and into the area early Wed morning which will provide a shot of light snow form most locations. Thursday and Friday: there is some model disagreement of what to do with the trough... Keep it out there, push it through, keep it dry, wet, tomato, tomatoe... It looks like the best chance of precip will be across the id panhandle and perhaps portions of eastern wa. But the confidence in this is quite low. Temperatures through the forecast period will remain cold for this time of the year. ... Nothing we haven't experienced the last several weeks. More snow, more cold, more snow, more cold, more snow, more cold, you know the drill. Nisbet Aviation 00z tafs: a weak cold front will move through the region this evening, bringing light snow to kgeg ksff kcoe kpuw airports. Cigs and visibilities should generally remain MVFR with this light snow, which should end by about 07z. Behind this front, the winds will become southwesterly, which should cause low stratus to form for kgeg, ksff and kcoe, which will likely persist through Saturday. Klws should remainVFR through the next 24 hours, but could have some brief MVFR CIGS this evening. Kmwh and keat won't see much if any snow. But their challenge is the formation of fog behind the front. Not confident enough to put fog in kmwh. Keat already has some fog with an MVFR cig, and computer guidance suggests it will gradually lower overnight.
