SYNOPSIS. A short but largely dry break period in the recent storm parade will end this evening as yet another system late tonight and into Saturday will bring another round of snow. High temperatures are expected to gradually climb well into the 30s over the next several days with the next potential winter weather system on or about Tuesday.
DISCUSSION. Tonight: Mainly dry weather persists across the Inland Northwest this afternoon as a shortwave ridge traverses across the region. Subsidence under the ridge brought areas of low clouds and patchy fog across the interior valleys, mainly along and north of Interstate 90. Some of these low clouds have been eroding this afternoon, but it wouldn't be surprising for more low clouds and patchy fog to return tonight, especially across the northern valleys.
Our brief respite from active weather will be coming to an end tonight as a deep low pressure system over the northeast Pacific takes aim at the region. This system is already highly occluded per satellite imagery, and its parent low will push northward tonight into Saturday. A few snow showers will be possible as early as late this afternoon/evening, but the main frontal band won't arrive until later tonight into Saturday.
Saturday: Moist isentropic ascent associated with the storm system's warm front will provide fairly widespread snow early Saturday morning across central Washington, and pushing east across eastern WA and the Idaho Panhandle through the morning and afternoon. At this stage, the more significant snowfall should remain generally along and north of Interstate 90. With the low- level easterly flow pattern of this storm system . strong orographic lift is expected to result in heavy snow along the east slopes of the Cascades, Okanogan Valley, Waterville Plateau, and Okanogan Highlands. Winter Storm Warnings and Advisories have been posted to highlight these concerns. Look for precipitation to be winding down Saturday evening, with lighter snow showers persisting over the Cascades and the Idaho Panhandle. Dang
Sunday and Monday: An upper level ridge over the Pacific Northwest will give the region a break from the precipitation and back into seasonal temperatures. There is a chance for light snow a bit longer in the Cascades, far northeast, and upper elevations of the ID Panhandle. The mountains should be precipitation free by early Monday. Moisture overnight Sunday into early Monday morning will bring patchy freezing fog to many of the northern valleys. However, much of Sunday and Monday will be a mild and calm day, but much of the region will remain under mostly cloudy skies. The temperatures will warm with many highs near or above freezing and lows in the 20s.
Tuesday and Wednesday: Unsettled weather with chances for more snow and/or rain-snow mix returns for much of next week. Models are continuing to show a late night/early Tuesday morning arrival in the Cascades as it moves into the region. Snow levels at arrival begin low with possibility of snow for all, but the levels rise with the day. Therefore, lower elevations in southeastern WA and parts of the ID Panhandle are likely to see a rain-snow mix in the afternoon. Looking into Tuesday evening and Wednesday, a majority of the region will be dry, but higher elevations will still see some lingering snow showers. As the days approach, eyes on the mountain passes will be essential, but low confidence in snow totals at the moment.
Thursday and Friday: The remainder of the week will be in an unsettled pattern. Models continue to show the probability for precipitation scattered across the Pacific Northwest. Temperatures will likely remain in seasonal normals with no indication for the bitterly cold temperatures like last week. JS
AVIATION. 00z TAFS: A variable cloud cover with some spotty fog lingers this evening but will be overrun by the next winter weather system approaching the aviation area from the west. Clouds and ceilings will thicken and lower as this system moves through along with potential for considerable snowfall, the most intense snowfall intensity producing IFR/LIFR conditions being between 15-22Z Saturday, but beginning as early as 10Z near KEAT. In addition there is spotty hit and miss convective showers forming over Southwest Washington and Northeast Oregon and these are moving to the northeast and may impact the far east TAF sites between 00-06Z Saturday. /Pelatti

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
