For today through Sunday, expect generally dry, variably cloudy but mild weather conditions with light winds across Northcentral Washington with afternoon high temperatures generally in the lower to mid- 60’s today through Sunday.
By Sunday night, the upper-level air flow will begin to shift to a more west than southwest flow aloft off the Pacific with the approach of a deepening trough in the Gulf of Alaska. This will mark the beginning of an active weather period for the work week.
The weather pattern change will happen on Monday as an upper level trof from the Gulf of Alaska drops down and positions itself off the coast. Northcentral Washington can expect a 20% chance of rain showers both Monday and Tuesday with a bit of a cool-down as well with afternoon high temperatures in the mid 50’s.
Expect a weather break on Wednesday with mostly sunny skies and highs in the mid 50’s.
We will see a return to unsettled weather on Thursday with a 20% chance of rain and afternoon high temperatures staying in the mid 50’s.
