Many chilly locations this morning as clear skies have allowed for good radiational cooling overnight. Expect areas of frost this morning as you are driving before surfaces start to warm from the sun. Under sunny skies, temperatures will be fairly similar to yesterday with highs today in the low 60’s. This afternoon we will see an increase in high-level clouds from the north as the gigantic high-pressure ridge off the coast begins to buckle ahead of the next weather system. The clouds will remain through the night which will keep temps a few degrees warmer that what we are seeing this morning.

Weather models agree that the stronger energy associated with Friday`s weather system will remain well to the north. The main impact will be a decrease in clouds, very dry Canadian air moving in behind it and an increase in northerly or westerly winds in some Northcentral Washington locations. The strongest winds will occur across the Okanogan Valley and Pasayten Wilderness Friday afternoon and evening with gusts up to 30 mph possible with even stronger gusts in the mountains. High temps in the mid 60’s.

The large area of high pressure in the pacific will re-establish itself on Saturday, Sunday and right through the middle of next week with sunny skies, light winds and afternoon high temperatures in the mid to upper 60’s.
