An upper level trough of lower pressure will result in breezy winds and slightly cooler temperatures across Northcentral Washington today. There are little to no clouds along the leading edge of this disturbance as it continues to move through the state.
So, for today, the Columbia Basin and Wenatchee Valley can expect sunny skies with a west wind 10-20 mph by this afternoon with possible gusts as high as 28 mph, afternoon high temperatures in the upper 80’s to lower 90’s.
On Wednesday through Thursday, winds will relax as the upper level weather system slowly moves away leaving behind mostly sunny skies and below normal temperatures with afternoon highs generally in the mid 80’s. Watch for some chilly overnight lows on Wednesday and Thursday night as well with temps in the higher elevations dropping down into the lower 40’s.
Temperatures will begin to rebound Friday and Saturday with sunny skies, as most lowland communities across the Inland Northwest will climb into the upper 80’s on Friday. Saturday will be several degrees warmer with places like Moses Lake, Wenatchee and Omak into the lower 90’s.
For Sunday and Monday, weather models are indicating a long-wave pattern over North America which will amplify early next week with a hot ridge of high pressure over the Western United States and a cool trough digging into the Great Lakes states. Both Sunday and Monday will be much warmer with sunny skies each day, light wind and afternoon high temperatures in the upper 90’s on Sunday to lower triple digit temperatures on Monday.
