A strong cold front from the Eastern Pacific is now moving through the state which will bring big weather changes to Northcentral Washington including very windy conditions and much cooler temperatures.
Expect a few clouds in our Thursday forecast as well with a sustained west wind 10-20 mph during the day increasing later to 15-25 mph with possible gusts to 35 mph, high temperatures today only in the lower 80’s. The Columbia Basin will see even windier conditions with speeds between 10-30 mph possible in some locations. Winds will then decrease through the night.
The upper level weather system will be out of the region by Friday where we can expect mostly sunny skies and slightly warmer temperatures with afternoon highs in the mid 80’s.
A very large area of high pressure will then settle in off the Pacific Coast on Saturday resulting in a dry west to northwest flow aloft through the middle part of next week. The Wenatchee Valley on Saturday will see sunny skies, alight northwest breeze and afternoon high temperatures in the mid to upper 80’s.
The ridging noses into the area Sunday into Monday bringing about a warming trend with highs on Sunday in the lower 90’s climbing to the mid 90’s on Monday.
By Tuesday, temperatures will begin to trend cooler as the ridge flattens in response to an upper trough passing north of the region into central and northern British Columbia Tuesday into Wednesday. Breezy winds are possible especially through the Cascade gaps during this transition to cooler temperatures. Northcentral Washington temperatures on Tuesday and Wednesday, under sunny skies, will generally be in the upper 80’s to lower 90’s.
