The main story during this period will be uncharacteristically hot weather for the beginning of the meteorological summer. This heat will arrive thanks to an unusually strong ridge of high pressure, currently centered off the Washington coast. Based on model data and satellite trends, the ridge is expected to migrate toward the Cascades by this afternoon and tonight. Despite the heat and dry conditions, winds will remain light with the thermal ridge firmly entrenched over the western half of Washington. Heat advisories have already been issued for the hottest populated areas of the region, Omak, Wenatchee and Moses Lake, however, this may need to be expanded somewhat for Wednesday and possibly Thursday as well. Northcentral Washington weather today calling for sunny skies, light winds and unseasonably hot temperatures with afternoon highs in the mid to upper 90’s.

Wednesday will be our hottest day with sunny skies and highs near 100 degrees, records for most locations.

The upper-level ridge gradually shifts east late Thursday but not before bringing us another unseasonably hot day with sunny skies and afternoon highs temperatures in the mid 90’s.

On Friday, cooler air advection increases over the area as a west-east upper jet slides over the area. Expect sunny skies on Friday and temperatures about 10 degrees cooler with highs in the mid 80’s.

A dry and windy weather pattern continues on Friday night and into Saturday with mostly clear skies, windy conditions and another 10-degree cool-down with highs in the lower to mid-70’s.

Our skies will remain mostly sunny on Sunday and Monday with seasonably cool temperatures in the lower 70’s.
