Area Forecast Discussion National Weather Service Spokane WA 306 PM PDT Sat Mar 28 2020
SYNOPSIS. A more active weather pattern will develop late in the weekend into early next week. The strongest storm system will arrive on Monday with windy conditions expected and the possibility of moderate snow near the Cascades. Mountain snow will linger into Tuesday and Wednesday with below normal temperatures expected through the middle of the week with a slow warming trend after that.
DISCUSSION. Tonight through Sunday night: The first of a couple of weak shortwave troughs is currently pressing up against the Cascades. The snow levels are expected to drop around 3000 ft. overnight with the passage. The current model guidance is bringing a little more moisture amounts. Six hour precip amounts are near half an inch for the crests and near a quart of an inch for the passes. The total snow expected overnight will be in the four to six inch range. The rest of the region remain in mostly isolated rainshowers. As the front passes across the rest of the Inland Northwest, rain shower chances become more widespread. Higher terrains around 3500ft will have a rain/snow mix or snow showers. Late morning and afternoon instability could mix graupel into the showers. The instability will increase into mid Sunday afternoon. An isolated lightning strike cannot be ruled out for the Northern and Eastern WA and the ID Panhandle. Lingering showers are expected for the ID Panhandle into Sunday night. Winds will be breezy across the Basin with sustained near 20 MPH gust near 30 MPH. Another, more robust, trough pushing a cold front will begin pass over the region Sunday night. The end of the period highlights the Cascades snow through late Sunday night with another couple of inches possible. The brunt of this system is expected to be early Monday AM. Overnight temps will be in the 30s to low 40s range. Sunday highs will be in the upper 40s to low 60s range. /JDC
Monday: Our most significant weather day of the week continues to be Monday. A vigorous and fast moving front will produce widespread precipitation including moderate to heavy accumulations in the Cascades. Confidence continues to grow that Monday will be quite windy and there will be potential for thunderstorms.
*Wind: Our wind forecast hasn't changed much for Monday. It still looks like southerly winds will blow in the morning increasing as high as 20 to 30 mph across central and eastern Washington. Mountain ridges in the Cascades and northeast Washington may experience gusts over 50 mph in the morning when our 850mb wind speeds peak between 40-50kts. By mid day the arrival of the cold front will produce a wind shift to the west or southwest. Look for our gust potential to increase as precipitation moves out of the Columbia Basin. Afternoon sustained winds of 20 to 25 mph will be common from Wenatchee and Vantage across the Columbia Basin, Palouse, and Spokane area. Gusts of 40 to 45 mph will be possible. Quick moving afternoon thunderstorms may contain outflow gusts of 50 mph or more over the eastern third of Washington into the Idaho Panhandle. In general, wind speeds in the 40 to 45 mph range aren't that out of the ordinary for our region. They typically cause scattered power outages and break some tree limbs. Areas of blowing dust are a good bet in central Washington near Moses Lake and Othello especially near fields that are being prepared for spring planting.
*Mountain Snow: The Cascade Crest will receive a dump of moderate to heavy snow in the Monday through Tuesday time frame. Stevens Pass will likely receive well over a foot of snow over a 24 to 36 hour period beginning early Monday morning. At this time it looks like peak impacts for the Cascade passes will be Monday morning with the arrival of the heaviest frontal precipitation. Snow levels will be around 3000 feet. More moderate to heavy snow is looking increasingly likely Monday night into Tuesday morning under the cold upper trough. Strong westerly flow combined with the prospect of a Puget Sound Convergence Zone may combine for a dump of late season snow. Total accumulations in the Idaho Panhandle won't be a high as the Cascades, but travel may be impacted at Lookout Pass Monday night into Tuesday morning.
*Thunderstorms: Monday afternoon thunderstorms will be possible along and just behind the cold front. Morning clouds may hinder destabilization, but the NAM and GFS continue to forecast enough cold advection aloft to yield enough surface based instability for the mention of thunderstorms over the eastern third of Washington into the Idaho Panhandle. Cells will be quick movers capable of brief heavy rain, small hail, and outflow gusts of 50 mph.
Tuesday through Friday: Tuesday and Wednesday look chilly, breezy, and showery as the Pacific Northwest remains under the cold upper trough. Snow levels will be quite low, capable of snow to the valley floors at night and in the morning. Shower coverage will peak during the afternoon hours Tuesday and Wednesday with a mixed bag of rain, snow, and graupel. Typical March showers. We should see a bit of a warming trend Thursday and Friday. The models have struggled to lock into how much warmer. /GKoch
AVIATION. 18Z TAFS: A saturated atmosphere over the region is bringing widespread cloud coverage and producing low to mid level cloud decks for the Spokane- Coeur d'Alene corridor and over the Palouse. Afternoon instability could produce isolated showers for the region. Best chances for these showers will be over the Cascade crest and over the higher terrain from the Okanogan Highlands to the Idaho Panhandle. Mountain obscurations through the day today. As more moisture is pushed into the region chances for showers will increase overnight and into Sunday morning with IFR/MVFR conditions possible. /JDC

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.
