The majority of the Inland Northwest will remain dry today into Monday with afternoon temperatures in the 30s. Our next opportunity for widespread precipitation will be Tuesday with a mix of rain and snow in the lowlands and light to moderate accumulations in the mountains. The remainder of the week looks mild for mid January but with unsettled conditions increasing the chances for light rain and snow.
Today through: The northern Cascades, then east across the northern mountains are the only areas with a threat of precipitation. Favorable orographics, weak isentropic assent, and available moisture that is gradually pushing north into Canada will all assist through the afternoon in an increased chance for high elevation snow showers. Drier air that has become entrained in the boundary layer will also roll north from the L-C Valley into the Columbia Basin and the Palouse through this afternoon and provide a brief period of partly sunny conditions as a sharp upper ridge increases a southwest upper flow across eastern Washington. As the day shifts into evening, lower elevation areas where some low- level moisture remains in the western Plains from Davenport west into the Waterville plateau, along with some eastern Cascade valley locations, my see patchy dense fog forming overnight this evening.
Monday through Tuesday morning: Monday will begin quiet under the influence of a predominately dry southwest upper flow. But all is not what it appears. A weak embedded upper wave will lift and roll over the ridge through the afternoon into the evening. The accompanying moisture, weak forcing, and weak isentropic assent should be enough to increase the risk for mountain snow and valley rain/snow mix across the northern Cascades, east across parts of the northern mountains, and over much of the northern Idaho panhandle. Any remaining showers will switch over to mostly light snow overnight Monday with accumulations staying less of an inch. Any threat for patchy fog will disappear across much of the CWA, but a weak overnight easterly surface flow through the Purcell Trench should retain enough boundary layer moisture to maintain a layer of low stratus through this area. /aky
Tuesday through Sunday: The Inland NW will transition to a milder weather pattern mid week as a mild and wet southwesterly flow develops. A series of weather systems will bring several rounds of precipitation. The first one arrives Tuesday. The lower atmosphere will still be cold enough for a threat of valley snow mainly in the Cascades as well as Okanogan Valley and Wenatchee area. The timing of precipitation looks to enter North Central WA in the morning where moderate snow accumulations are possible in the Cascades with light amounts for Wenatchee and Omak areas. For Eastern WA/N Idaho most of the precipitation is expected in the afternoon where a rain/snow mix is more likely in the valleys with temps in the mid to upper 30s. The next system arrives Wednesday night into Thursday. This one has the potential to be wetter with moderate to locally heavy snow in the Cascades. Snow levels also look to be slightly higher with mainly valley rain/mountain snow south of I-90 and valley snow changing to rain by Thursday afternoon north of I-90. After that the mild pattern continues with mainly valley rain/mountain snow expected as the mild southwest flow continues. Ensemble guidance shows snow levels climbing to 3000-5000 feet Friday through the weekend (lowest near the Canadian border). JW
AVIATION. 00Z TAFS: TAF sites are forecast to remain dry over the next 24 hours as a weather disturbance passes to the west. Easterly flow aloft will continue low level stratus at EAT, with ceilings gradually lowering overnight. MWH-LWS-PUW will remain clear for several hours tonight, but likely not long enough for fog to form as dew point depressions remain around 10 degrees. The forecast is much more difficult for GEG-SFF-COE as temperatures hover just 3-5 degrees above the dew point. For now, have indicated FG at GEG and SFF but stronger easterly flow at COE should keep them clear overnight. Wilson

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.
