A cold and deepening upper level low is moving into British Columbia this morning. Associated with this system is a long-fetch moisture train that continues to take a stab at the Pacific Northwest. Fairly heavy precipitation totals have been reported in the Cascades and is now spilling over onto the eastern slopes of the Cascades. Area rivers and stream are beginning to see the effects of the increased precipitation especially in the Cascades, namely the Stehekin River where river levels have begun increasing above flood stage at 22 feet. Winds have also begun picking up out of the south with gusts across the southern Columbia Basin between 25 and 30 mph and select locations through the Okanogan Valley seeing isolated wind gusts 40 to 45 mph. Peak winds are expected through late morning before tapering off with the onset of precipitation. Gusty winds may also bring areas of blowing dust through the Wenatchee-Moses Lake region where very little precipitation has been observed. Northcentral Washington weather for today expect cloudy skies with a 60% chance of rain, a 50% chance tonight with afternoon high temperatures today generally in the upper 50’s.
On Friday, the trough axis slides south along the West Coast allowing a ridge to begin pushing into British Columbia from the northwest. Friday through the weekend our weather will be mostly sunny and cooler with afternoon highs each day in the mid to upper 40’s.
Colder than normal temperatures will continue Monday into next week, and the potential for precipitation increases again as early as Monday night due to an approaching warm front. Snow is the most likely precipitation type for essentially all of our forecast area. The Wenatchee Valley and Columbia Basin can expect mostly cloudy skies both Monday night and Tuesday with a 20-30% chance of rain mixed with snow, highs on Tuesday around 45 degrees.
For Veterans Day Wednesday, we will see mostly sunny skies with afternoon high temperatures about normal for this time of year, in the mid to upper 40’s.
