Weather 11-26-19


A deepening area of low pressure drops into the Southern Oregon Coast throughout the day with a 30% chance of snow developing late this afternoon with high temperatures in the mid 30’s. Northcentral Washington can also expect increasing winds tonight out of the northeast gusting to 22 mph.

As the weather system continues to move east on Wednesday, winds will continue to increase as well as a 60% chance of wrap-around snow showers throughout the day with cold wind chills and afternoon highs only in the lower 30’s. About 1-2” of snow accumulation expected on Wednesday. Light to locally moderate snow will be possible in the Cascades and along the Highway 97 corridor around Wenatchee and Chelan. Also on Wednesday, a tight packing of pressure gradients will create the strong winds generally blowing from north or northeast to south/southwest. The strongest speeds will impact the North Idaho Panhandle, Columbia Basin and Okanogan Valley. Sustained winds of 25-35 mph with gusts to 45 mph are likely in these areas. Localized stronger sustained winds of 35-40 mph with gusts of 50-60 mph are possible. The Wenatchee Valley will see winds Wednesday 15-25 mph with gusts to 31 mph.

For Thanksgiving Day on Thursday, expect maybe a slight chance of morning flurries then mostly cloudy skies with afternoon high temperatures in the lower 30’s.

For Friday and Saturday, the upcoming weekend will start off cold and dry as a stable weather pattern develops. The area of low pressure over Oregon will fill and slowly drift into the Central U.S. while a another low drifts into the Eastern Pacific. High pressure will strengthen between these features and deliver the dry weather. Sunny skies Friday, with mostly sunny skies Saturday, highs both days in the upper 20’s to around 30 degrees.

For Sunday and Monday, weather models are starting to trend toward a more active weather pattern with the offshore low coming inland and bringing an increasing risk for precipitation. Northcentral Washington will see a chance of flurries each day with high temperatures Sunday near 30 warming to the mid 30’s by Monday.
