Temperatures across Northcentral and Eastern Washington should be down a few degrees today compared to yesterday, but it will still be quite warm, under sunny skies, highs will top out this afternoon in the lower to mid-90’s. Southwest winds of 10 to 15 mph will be common today as well and along with low humidity will raise fire concerns in the valleys East of the Cascades. Dry and breezy winds will be an ongoing issue each evening through Friday.
On Thursday, cooler air will spill across the Cascades leading to a noticeable drop in temperatures all across the Inland Northwest. Along with sunshine and breezy northwest winds, high temperatures tomorrow will reach the upper 80’s.
For Friday and Saturday, the Inland Northwest is forecast to remain mostly dry, with temperatures on Friday in the mid 80’s and near seasonal temperatures on Saturday with highs in the upper 80’s. A very strong ridge of high pressure builds over Northcentral Washington on Sunday with sunny skies and temperatures in the mid 90’s. Under lots of sunshine on Monday and Tuesday afternoon high temperatures will reach 100 degrees or higher, especially on Tuesday. This is potentially dangerous heat, especially those with higher sensitiveness or those who regularly take part in outdoor work or other activities. Some breeziness also returns toward the Cascade gaps as we go into Tuesday as the ridge axis shifts east and the cross-Cascade gradient increases.
