The weather system that brought thunderstorm activity last night is pushing to the east leaving behind clear skies and light wind. Northcentral Washington weather today will be sunny and hot with afternoon high temperatures in the mid 90’s.
On Thursday, a trough of low pressure makes its arrival with more clouds, some moisture and instability. The Columbia Basin and Wenatchee Valley can expect mostly sunny skies tomorrow and still hot with afternoon highs in the mid 90’s. By tomorrow night, clouds will begin to move in ahead of the weather system.
The trough pushes to the east on Friday allowing a stronger area of low pressure to settle over British Columbia and Alberta. This will bring a consolidated westerly flow across the Inland Northwest leading to breezy winds at the surface especially for Friday afternoon. Humidity values will be elevated through the weekend with much cooler temperatures. Weather for Friday and Saturday will be partly cloudy with a 20% chance of showers each day and much cooler with afternoon high temperatures in the lower to mid-80’s.
Sunday will be cooler than normal as well with sunny skies and highs in the lower 80’s.
As we get to Monday and Tuesday next week it will be back to more normal weather this time of year with sunny skies each day and afternoon highs in the mid to upper 80’s Monday and into the lower 90’s by Tuesday.
