Weather 5-3-21


Today’s weather will start off with mostly clear skies and then increasing cloud cover by late afternoon thanks to a shortwave feature that will flatten out our ridge of high pressure.

Northcentral Washington weather today will be mostly cloudy and along with steady northwest breeze, afternoon highs will top out near 70 degrees.

On Tuesday, skies should clear behind the departing shortwave and temperatures will once again be around or slightly above seasonal normal with highs in the Columbia Basin and Wenatchee Valley generally in the upper 60’s to lower 70’s.

Weather models are in good agreement that an upper level ridge of high pressure will be well established over the Western United States by Wednesday morning. This will allow for skies to briefly clear with partly cloudy conditions and temperatures into the lower and mid-70’s. While this ridge is overhead, a deepening low off the coast will start to migrate eastward. Winds will shift easterly and clouds will begin to increase Wednesday afternoon ahead of the approaching low.

A cold front will move in on Thursday bringing clouds and a 30% chance of showers with highs, still mild, into the mid 70’s.

By Friday, high temperatures will plummet behind the front, about 10 to 15 degrees cooler than Thursday`s highs. Weather forecast for Friday calling for mostly cloudy skies, a 40% chance of showers and much cooler with afternoon highs in the lower 60’s.

Expect partly cloudy skies for both Saturday and Sunday with seasonal high temperatures in the upper 60’s.
