A weak shortwave weather disturbance will pass through today with high clouds and breezy northwest winds with gusts to around 25 mph in the Wenatchee area and around 20 mph across the Waterville Plateau and Moses Lake Area this afternoon. High temperatures today in the mid 80’s.
A strong ridge of high pressure will then begin to build over the region on Tuesday with sunny skies, light winds and warmer temperatures with highs tomorrow near 90 degrees.
For Wednesday and Thursday, weather models continue to advertise much above average temperatures with widespread upper 80s to mid-90s across the lowlands of Central and Eastern Washington both days. We are looking at near record heat for central and southeast Washington on Wednesday as a sharp high-pressure ridge moves inland. Wenatchee Valley weather for Wednesday and Thursday calling for mostly sunny to sunny conditions and hot afternoon high temperatures with mid 90’s expected both days.
Thursday continues to be the day with the highest potential weather impact this week. Gusty winds late in the day combined with hot temperatures and low humidity raise concerns for grass and brush fires. Winds aloft aren`t expected to be particularly impressive, but cool marine air spilling through the Cascade gaps will likely produce sustained winds of 20 mph with gusts of 30 to 35 mph in places like Wenatchee, Chelan, Vantage, and Waterville early Thursday evening. Friday through Sunday, temperatures will remain above average under sunny skies and light wind, highs each day in the upper 80’s to lower 90’s.
