After reaching a high temperature yesterday of 93 degrees, we can expect another hot weather day with afternoon highs today approaching 100 degrees all across Northcentral Washington. The pressure gradient across the Cascades will tighten late this afternoon producing breezy conditions tonight out of the northwest 10-20 mph. This in combination with relative humidity’s in the teens has lead to a red flag warning for much of Eastern Washington.
An upper level trough is moving south through British Columbia and as it moves into Alberta tonight, a dry cold front will move across the Inland Northwest cooling us off slightly on Saturday with highs in the low 90’s. Back to even more heat on Sunday as well as through the early part of next week as the ridge of high pressure in the Pacific intensifies.
Afternoon high temperatures on Sunday are expected to climb into the upper 90’s with 100 degrees possible for Monday and Tuesday. Heat Advisories may be considered by early next week for Moses Lake, Wenatchee, and Omak.
A bit cooler by mid-week as another weak cold front moves through dropping our very hot high temperatures down into the low to mid 90’s.
