Expect an active wet period through this afternoon as an area of low pressure deepens and drops through the state. The wettest area looks to be the Okanogan Valley and Highlands with three to four tenths already measured. A surface low over Southwest British Columbia will drop south across the Cascades to northeast Oregon over the next several hours with a good swath of moderate precipitation along its track. Precipitation chances quickly shut off by early afternoon in Northcentral Washington with somewhat breezy north winds to follow, high temperatures today in the upper 50’s.
Wednesday looks to be dry and mostly sunny with light winds and cool afternoon temperatures with highs tomorrow in the low 60’s.
On Thursday, there is good weather model agreement that a high-pressure ridge off the coast will spread inland on Thursday bringing light winds, mainly clear skies and warmer afternoon high temperatures into the mid 60’s.
By Friday and the weekend, we can expect dry and mild weather as high pressure remains locked into the Eastern Pacific. Under mostly sunny skies, high temperatures Friday through Monday will be in the mid 60’s with overnight lows in the low 40’s.
