A zonal weather pattern has set in over the Pacific Northwest meaning partly cloudy skies and unseasonably warm temperatures. Northcentral Washington weather for today calling for increasing clouds, calm wind conditions with afternoon high temperatures in the mid to upper 40’s.
Mostly cloudy for Saturday and a bit warmer with highs in the afternoon around 50 degrees.
Saturday night and Sunday look like the most active weather periods of the next 7 days as a strong upper level trough is expected to push a warm front and then a cold front across the region on Sunday. The Wenatchee Valley can expect widespread precipitation that will start out as light precipitation early Sunday morning with moderate showers expected by afternoon. There is a 60% chance of precipitation Sunday with afternoon high temperatures still on the mild side into the upper 40’s. Most valley locations could wake up to a dusting of light snow Sunday morning with up to 10 inches of heavy, wet snow possible for Stevens and Snoqualmie Passes. Weather models are also pointing to the development of breezy/windy conditions for late Sunday afternoon into the overnight hours with wind speeds in the Wenatchee Valley around 10-20 mph.
From Monday through Thursday, the development of an upper level ridge of high pressure still looks likely with partly cloudy skies each day and afternoon high temperatures warming into the mid 50’s by the middle and end of next week.
