Temperatures today should be about 3 to 5 degrees warmer than what we saw on Sunday as high pressure continues to build across the Inland Northwest. In general skies should be clearer than yesterday as well with plenty of sunshine today with Northcentral Washington afternoon high temperatures in the upper 90’s in Wenatchee and Omak to triple digits in Moses Lake.
Tuesday will also be hot, under sunny skies, expect readings solidly in the upper 90’s for everyone, and a few 100’s in the Basin. We will also see a northwest breeze 10-15 mph throughout the day and into Tuesday night.
By Wednesday, enough cooler marine air will have filtered into the region to cool everyone by a few degrees, but still a toasty day with sunshine and afternoon high temperatures in the mid 90’s.
The hot temperatures, breezy winds and low humidity’s will once again raise wildfire concerns. But the winds likely won`t be strong enough for extreme fire danger.
Another push of marine air will spill through the Cascade gaps into Northcentral Washington Thursday as a broad upper level trough of low pressure moves inland. West winds of 15 to 20 mph with gusts of 25 mph will be possible for Wenatchee, Chelan, Waterville, and Vantage. Under sunny skies, high temperatures on Thursday should be about five degrees cooler than Wednesday with afternoon readings in the mid to upper 80s for Spokane, Colville, Omak, and Wenatchee. Highs near 90 are expected for Moses Lake, Ephrata and Quincy.
For the upcoming weekend, a broad trough over southern British Columbia will produce enough onshore flow to keep our region from getting too hot. With sunny skies, afternoon high temperatures on both Friday and Saturday will be near 90 degrees with lower 90’s expected for Sunday
