Area forecast discussion, Jan 25, 9:59 PM PST, 3 hours 19 minutes before
Area Forecast Discussion National Weather Service Spokane WA 959 PM PST Mon Jan 25 2021 .SYNOPSIS... Areas of light snow will continue into the early evening hours over far Eastern Washington and north Idaho tonight. Additional rounds of snow are expected this week beginning Tuesday night. This mid- week event will likely impact travel at times, especially over Central and Northeast Washington into the Idaho Panhandle. && .DISCUSSION... Tonight and Tuesday: Light dusty snow continues to drift across eastern WA and parts of the Idaho Panhandle. This will continue into the early evening hours and the move northward into Canada. Overnight into Tuesday, the elongated trough moves further inland, but with limited moisture. Tomorrow, dry conditions are favored with light winds. There will be a relatively moist boundary layer and, with light winds, will keep the region wide stratus in place through the day. With this cloud deck and limited warming today, tonight's lows will be cool and below normal with the trough in place. Tuesday's highs will be below seasonal and only reaching temperatures in the upper 20s and low 30s regionwide. Tuesday night through Wednesday: As the low continues to churn off the northwest coast, the active weather returns Tuesday night with the arrival of a shortwave trough and cold, wet conditions make their way inland. The mid-week event's arrival and precipitation intensity continue to remain relatively persistent across model runs. Snowfall will be the main concern with this event. Winds will be light and Tuesday night may be breezy in the Basin and Cascade slopes, but only reach peak gusts to 15-20KTs. Snow levels will remain low keeping all precipitation snow, except for the Lewiston area and lower Basin which may receive a rain-snow mix depending on time of day. Snow will arrive overnight Tuesday moving in from the southwest. Initial impact will be in the Cascades and slowly becoming widespread on Wednesday. Models continue to produce the greatest snowfall in the Waterville Plateau, Okanogan Highlands, and Eastern Cascade slopes. 24 hour snow amounts may reach 4-6" across those areas, in locations such as Wenatchee, Waterville, and lower Methow Valley. The Spokane-Coeur d'Alene corridor, throughout the upper Basin, and into northeastern WA, snow from 1-3" is possible in the low lands and higher elevations may see up to 4-6" in 24 hours. We will need to look further into issuing winter weather advisories across part of the Inland NW. This is due to the significant snowfall, in only 24 hours, for some of these locations. The Wednesday morning commute will need to be approached with caution due to the snow depth in the morning and ongoing snowfall during the day. JS Wednesday night through Friday: Lingering light snow, mainly in the mountains. Friday's snow will be more centered over the Panhandle. Less than an inch of additional snowfall is expected in the valleys. Temperatures could be warm enough for the lowlands to mix in with or transition to rain by the afternoons. Saturday and Sunday: This weekend into early next week looks to bring additional chances of moderate to possibly heavy mountain snow. Much of the lowland snow accumulations will probably be too warm for significant snow accumulations and instead receive rain or a mix, but this forecast may change. Valleys north of the metro may stay cold enough for significant snow. RC && .AVIATION... 06Z TAFs: Widespread stratus expected tonight due to light winds and continued moisture in the boundary layer. CIGS and visibilities have improved over the Basin and eastern slopes, but there may be some patchy fog in the early morning hours. IFR to marginal VFR expected through most of the period for stratus induced ceilings. Clearing expected by the end of the TAF period before another shortwave is exepcted to bring another round of snow to the region starting with EAT late Tuesday. /JDC && .PRELIMINARY POINT TEMPS/POPS...
