The warmest pattern of the year so far is setting up over the Inland Northwest. This includes an upper level area of high pressure centered over Northern Arizona and ridge axis extending north across the inter-mountain west. Temperatures will increase slightly Wednesday over what we experienced Tuesday and then max out Thursday. The increasing temperatures are a result of a trof digging off the west coast which will further amplify the ridge.

There is an extreme heat warning for most of Northcentral Washington until 8:00 p.m. Friday night. Daytime max temperatures will flirt with daily record highs Thursday and Friday during the peak of the event.

Abundant sunshine expected across Northcentral Washington today with afternoon high temperatures between 100-105 degrees.

Possible record high temperatures on Thursday with readings by late afternoon in the 105-110 range.

Besides the warm temperatures, the biggest concern over the next 48+ hours will be fire weather with hot and dry conditions having the high potential of igniting fires.

An upper level low continues its slow approach to the Pacific Coast with its accompanying cold front. With this, the cool down after peaking Thursday is holding off a little bit longer than expected. Temperatures only look to cool a few degrees on Friday with lots of sunshine and afternoon high temperatures between 100-105.

The departure of the ridge begins to inch its way out of the Pacific Northwest slowly over the weekend. Saturday and Sunday will be cooler, but still above normal with widespread highs in the mid-to-upper 90s. Moving into next week, the cold front passage will bring temperatures back closer to normal in the upper 80’s. Winds will continue to be a bit breezy through the weekend, with another spike in winds on early next week with wind around 10-20 mph.
