An area of low pressure moving into Northern California will shift the ridge of high pressure off the Washington coast eastward today through Friday and will allow a zonal flow weather pattern to set in over the Pacific Northwest. Northcentral Washington can expect lots of sunshine today, calm winds and afternoon high temperatures in the mid 40’s.
We will see a few more clouds on Friday with highs in the mid to upper 40’s.
Our weather pattern begins to change on Saturday as an area of low pressure pushes into British Columbia dragging a pretty good amount of precipitation with it. Expect increasing clouds during the day Saturday and slightly warmer temperatures with highs in the upper 40’s.
Overnight Saturday and Sunday morning will be the most active weather period of the forecast with a 60% chance of snow early Sunday morning changing over to rain later in the day with afternoon high temperatures once again near 50 degrees. Stevens Pass will be subject to a significant amount of snow, possibly up to 10 inches or slightly more through early Monday morning. The Wenatchee Valley could see an isolated rain shower or two early Monday morning as the storm system moves away with partly cloudy skies by afternoon, highs in the upper 40’s.
From Tuesday through Wednesday we are looking at dry weather as the next upper level ridge builds over the Inland Northwest. Under mostly sunny skies, high temperatures both Tuesday and Wednesday will generally be in the mid to upper 40’s.
