Area Forecast Discussion National Weather Service Spokane WA 946 AM PST Fri Jan 28 2022

SYNOPSIS. Low clouds and patchy fog will persist across Central Washington and portions of Eastern Washington and North Idaho into Saturday. More active weather is forecast to arrive on Sunday with increased chances for mountain snow and wintry precipitation for the valleys. A drier and cooler weather pattern will likely return on Tuesday and continue through the remainder of next week.

DISCUSSION. Today through Saturday Night: An upper level ridge will gradually flatten into Saturday but observed weather will not change much as low clouds persist over much of the area beneath a temperature inversion. As of 2 am satellite imagery revealed stratus from Kettle Falls down through Davenport, Sprague, and Pomeroy westward into the East Slope Cascade valleys. With boundary layer winds changing little today these areas will likely stay in the clouds with limited temperature rises from this morning's lows. The good news is the stratus layer is running from near 3000-4000 feet MSL so fog is limited to mainly this elevation range and above most towns. East of these areas from the ID Panhandle, Pend Oreille county, Spokane area, Palouse, and Lewiston area the clearing from the easterly gradient should allow for more sunshine today although radiational fog has formed in many of the river valleys and this could continue to expand further into the morning. So some towns may have to wait until the late morning or early afternoon for the fog to dissipate. The clearing has also allowed for colder temperatures this morning with even some local single digits. The fog and stratus is expected to have a near repeat performance on Saturday.

The next weather system approaches Saturday night. Increasing mid and high clouds should limit fog potential although areas of stratus will continue especially in Central and northern Washington. Snow may begin late Saturday night along the Cascade crest. JW

Sunday to Monday: Sunday morning an incoming weather system will spread snow with a rain and snow mix in the deep Central Basin from there to the Idaho Panhandle by afternoon on Sunday. Warmer air will try to creep into the Palouse toward Spokane by Sunday afternoon which will moderate snow accumulations to around an inch or two potentially.

Snow amounts still look heaviest in the Cascade mountains and the Idaho Panhandle mountains throughout the event. Valleys of the eastern third of Washington generally look to have less significant snowfall with 1 to 3 inches with the Panhandle getting an inch or two more by Sunday evening. The Central Basin into the Okanogan valley won't have much precipitation potential overall as terrain shadowing in westerly flow aloft will limit rain and snow Sunday.

Monday will be drier and a little breezy with continued mountain snow showers especially in the Idaho Panhandle.

Tuesday and Wednesday the region looks to be in colder and dryer northwesterly flow but showers will linger in the higher terrain of the Idaho Panhandle. There are signs of additional waves in northwest flow that will re-energize mountain showers in the Panhandle but the rest of the inland northwest will be mainly dry and on the cool side. TC

AVIATION. 18Z TAFS: A blanket of low stratus cover with marginal VFR ceilings will persist in the lee of the Cascades out into the Okanogan Valley/Highlands and into the western Columbia Basin. There is a mix of fog and low stratus across the Spokane/Coeur d'Alene corridor northward into Colville-Sandpoint-Bonners Ferry. These low clouds will see a better chance of mixing out with VFR conditions for the afternoon with high cirrus clouds filtering across. Persistent dry southeast winds into Lewiston and Pullman/Moscow terminals will keep low clouds out of these areas. A redevelopment of fog is possible for KGEG-KSFF-KCOE-KCQV- KSZT-K65S late tonight with the forecast following persistence. Confidence remains high that dry air will keep Pullman and Lewiston airports clear of low clouds tonight into Saturday. /SVH
