SYNOPSIS. Scattered light snow returned to the Inland Northwest today. This prolonged event will continue overnight into early tomorrow afternoon. Additional snow chances will come Tuesday night through the weekend. Most impacts to commutes will begin Wednesday into the latter half of the week.
DISCUSSION. Tonight through Tuesday: A low off the British Columbia coast is dragging its way southward and will soon be resting off the Pacific Northwest coastline. As this low lingers, there will be a light, prolonged snowfall across much of the region, especially in northeastern WA and northern Panhandle tonight into early tomorrow afternoon. There were scattered snow flurries across the Inland NW this afternoon, but no accumulation was noted in lower elevations. Over the next 24 hours, from early evening into Monday morning, most of the region will receive less than 1" of snow and 1-2" if lucky. The greatest snow totals will be in portions of the Cascades and northern mountains with less than 5" expected over 24 hours. Each model run, over the past 24-48 hours, continue to forecast lower QPF values. Overall, the outlook is a slow moving system with very light snow through tomorrow afternoon.
This is not an out-of-season event, but caution should be taken tonight and in tomorrow's morning commute. Most snowfall will be overnight with temperatures remaining below freezing. This could lead to icy surfaces or slushy roads, especially in the morning hours.
Tuesday will be a brief break in an active week ahead, with dry conditions and mostly cloudy skies. Temperatures on Monday and Tuesday will remain near seasonal with highs into the upper 20s and 30s. Overnight lows will be warmer with widespread lows in the upper teens and 20s. With the extended cloud coverage, the lack of clear night skies will prevent very brisk, cold nights ahead, compared to last week. JS
Tuesday evening through Sunday: An active weather pattern is in store this week. A messy longwave trough will set up off the West Coast, and multiple impulses will move through before a longwave ridge pushes the trough to the east at the beginning/middle of the following week. This means several days with precipitation for the Inland Northwest and drier weather to follow. Wednesday will be the day to watch.
* TIMING AND POTENTIAL: Precipitation chances return late Tuesday afternoon to the Cascades. By Wednesday morning, much of the forecast area will be in or near snow showers. This likely excludes the LC Valley, which recent model runs have been keeping rather dry until Friday. Precip chances continue Thursday but the precipitation won't be as widespread or heavy as Wednesday, and it will be more focused in the northern mountains. Heading into Thursday night and Friday, most of the precipitation will shift into the Panhandle and perhaps the eastern most Washington counties. Saturday and Sunday, precipitation chances look higher for the forecast area as a whole. * PRECIPITATION TYPE: Most of the precipitation this week is expected to be snow, and some rain could mix in roughly along and south of the I-90 corridor in the afternoons. * WEDNESDAY SNOW AMOUNTS: There is still a bit of disagreement between models regarding what the highest snowfall amounts will be, but there is good agreement that the higher amounts will be Wednesday in our northern Washington zones and Waterville Plateau. This is generally north and west of the I-90 corridor. An average of various model amounts would be about 2 to 6 inches for this area, with less than an inch over SE WA and lower ID. /RC
AVIATION. 00Z TAFs: Spotty, light snow has been making it's way across the region this afternoon. Scattered snow will continue, but the frontal band, which could bring a few hours of steady light snow is expected later tonight. Some of the eastern Cascade slopes are starting to receive visibility reducing snow, but it will reach far eastern WA and the Panhandle closer to 06-10Z. The cloud deck continues to thicken, with lower ceilings. Passing snow is expected to continue to bring mist and lower visibilities. IFR and MVFR conditions are likely overnight. JS

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.
