Area Forecast Discussion National Weather Service Spokane WA 954 AM PST Thu Nov 21 2019

SYNOPSIS. A cool, dry and stable weather pattern is expected Thursday through Saturday followed by the potential for light precipitation Sunday. An increasingly active winter-like weather pattern is expected to develop next week.



DISCUSSION. Today through Saturday . High pressure will be over the region today for warm and dry conditions. Some fog and low clouds can be expected for a few of the northern mountain valleys, and along the Snake and Clearwater rivers near the L-C valley. This should mix out fairly quickly after sunrise. Temperatures will continue to be above normal with highs in the 40s. Satellite imagery is showing a fast moving cold front moving across the Pacific this morning. The front will weaken dramatically as it moves through British Columbia tonight. There is very little moisture associated with the front and the forecast is dry with just some increasing high clouds. What this front will do is shift the winds from northeast today to southwest tonight and Friday. This will increase moisture across the region a bit for tonight and that will allow a little more fog development Friday morning. Another beauty of a day is expected Friday with temperatures just slightly cooler. The ridge will continue to flatten Friday night and Saturday as another upper low tracks through northern B.C. The low will drag a warm front through the region and give a chance for light precipitation for the Cascade crest Saturday afternoon. Precipitation will be light with generally under 0.05. Snow levels around 4500 feet will give a chance for snow down to about Stevens Pass but accumulations will be light and generally under a half inch. The morning inversion will be quite strong this morning and Friday morning, but an advisory is not likely at this time. Tobin

Saturday night and Sunday: The aforementioned shortwave will usher a weak frontal system through the region. The cold front passes through Saturday evening and Sunday bringing a better chance for precipitation. Swift westerly flow accompanying the frontal system will result in a modest rain shadow in the lee of the Cascades and keep the highest precipitation amounts focusing over the Idaho Panhandle and Cascade Crest. The Central Panhandle Mountains of Idaho stand a decent shot for a few inches of snow including Lookout Pass. Heavier snow amounts are expected along the Cascade Crest which could lead to snowy travel over Stevens and Washington Passes. If planning to cross the Cascades this weekend, Saturday will feature less weather impacts. The valleys of NE WA and N ID could see a light snow Saturday night and Sunday morning before precipitation switches to rain or essentially ends but confidence is low for accumulations at this time. As the front sags southward Sunday night, increasing northwest flow will continue to bring snow showers to the lower Idaho Panhandle and Camas Prairie. Snow accumulations around Winchester and Deary look to be light but a quick burst of a half inch or more cannot be ruled out. Winds will become breezy from the west Sunday afternoon from the Wenatchee River Valley to the Palouse. Wind speeds Sunday afternoon will increase toward 10-16 mph with gusts around 25-30 mph. Overall, models are in decent agreement regarding the quick hitting, and generally light precipitation event

. MUCH COLDER WITH POTENTIAL FOR SNOW TUESDAY THROUGH THANKSGIVING .

Monday through Thursday: A major shift in the weather pattern is on tap for the upcoming holiday week. Confidence continues to increase for a deep trough to carve out much of the Western US and allow cooler, Canadian air to infiltrate the Inland NW. In addition to the cold, several pieces of energy dropping into the trough will bring a chance for precipitation. There is a general consensus amongst the forecast models that a bulk of this energy will skirt to our south but there are plenty of members still indicating enough energy will pivot to the north to bring a chance for snow. At this time, snow amounts remain very uncertain with the range for most lowland locations ranging from 0 to 8 inches over the multi-day period So given this uncertainty. it would be best at this time to start preparing for potential snow and consider what might be the best travel days to reach your destination safely. From what we are seeing in the models today, looks like Monday will mainly feature snow showers for the passes and the potential for more widespread light to moderate snows could arrive roughly in the Tuesday-Thursday time-frame. These details will become sorted out in the coming days.

As for temperatures, look for high temperatures to begin to crash Monday and continue well into the end of the week. Afternoon highs start off in the 40s and upper 30s Monday then struggle to make it out of the low to mid 30s by Thursday. Overnight lows will be dip into the 20s early in the week then teens by the end.

Winds will become gusty from the north and northeast on Wednesday with a stronger push of cold continental air. Look for winds down the Purcell Trench, Okanogan Valley, and across the open Basin to increase between 15-25 mph with gusts in excess of 35 mph possible. /sb



AVIATION. 12Z TAFS: High pressure will be over the region today for sunny skies and light, variable winds. Patchy fog will burn off along the the rivers of the northern valleys, along the Spokane and Columbia rivers, and along the Clearwater and Snake river near Lewiston. Expect VFR conditions today toward Friday morning. After about 13Z Friday conditions look more favorable for local fog and stratus to form. VIS down to 1 mile IFR conditions are possible at KGEG, KSFF, KCOE as valley fog. KMWH and KLWS will also have some fog potential as well but toward 18Z lifting of the fog is expected at most sites. There is potential for KMWH to hang onto a low stratus CIG after 18Z Friday so check back on the next TAF issuance to see where we go with that trend. TC
