On satellite imagery, it is evident that the deep off-shore trough of low pressure is pushing into the Pacific Northwest. The upper level trough swings through Northcentral Washington late morning/early afternoon and will favor the Cascades wonderfully for large snow accumulations, this is no doubt. Weather models continue to hit this hard with expected 1 to 3 feet of snow through late Friday, even periods of 1-2″/hour or more for Stevens Pass. By the time the precipitation pushes east into the Wenatchee Valley and Columbia Basin wind begins to ramp up by mid-day into the evening hours. Northcentral Washington weather forecast for today calling for cloudy skies, a 50% chance of rain mixed with snow and windy out of the northwest 20-25 mph with gusts to 38 mph, highs this afternoon in the mid 40’s.
The secondary wave of energy will keep the breezy to gusty winds in place across the Columbia Basin and much of the Wenatchee Valley on Friday as well with 15-25 mph winds gusting to almost 40 mph at times. There is also a 30% chance of showers tomorrow with highs once again in the mid 40’s.
By the weekend, a ridge of high pressure will begin to build in over the west as our weather quiets down and warms up. Forecast for Saturday and Sunday calling for mostly sunny to partly cloudy skies, light wind, with afternoon high temperatures in the mid to upper 40’s Saturday and upper 40’s and lower 50’s Sunday.
Monday through Wednesday looks quiet too with mainly partly cloudy skies each day with seasonal high temperatures into the upper 40’s.
