The large area of low pressure that brought us cooler temperatures and some much-needed rainfall over the weekend is now spinning its way through Montana where a winter weather advisory is in place today. As the system continues to move east, we will see some windy conditions down the Okanogan Valley this morning gusts expected to peak up to around 40 mph late in the morning. Wenatchee Valley wind will be around 8-13 mph and will gradually weaken through the afternoon. Highs today will be around 80.

On Tuesday through Sunday, we will see a fairly progressive west to northwest flow regime that will dominate the extended weather period. Temperatures in this flow regime will buck back up to normal or slightly above normal on Tuesday and Wednesday just ahead of the next weather system and then retrograde back to near or slightly below normal for the rest of the week and into next weekend.

Highs on Tuesday and Wednesday will climb into the mid 80’s cooling back to the upper 70’s to near 80 Thursday through the weekend. We will also see the return of smoke and haze on Wednesday especially over the western zones nearest to these fires with patchy and only occasional noticeable smoke wandering into the eastern zones from here on out.
