A dry and quiet weather pattern is expected through Friday along with a warming trend as the upper level flow transitions from west to southwest in advance of an upper level trough late Friday night.
For today, Northcentral Washington will enjoy sunny skies and warmer temperatures with afternoon highs near or at normal for this time of year into the upper 80’s. Winds look lighter compared to the past few days, which is good news for ongoing fires, especially the Desert Canyon Fire.
The Wenatchee Valley can expect sunny skies for Friday as well with high temperatures warming into the mid 90’s. This combined with low relative humidity and south-southwest winds increasing to 5 to 15 mph ahead of a cold front will elevate the fire weather environment over Central Washington.
For Friday night and Saturday, the latest weather models are coming into agreement that Friday night will bring a dry cold front passage. There will be a small chance of showers up along the Cascade crest but the main impact will be increasing winds through the Cascade gaps during the evening and general downslope gustiness all along the east slopes of the Cascades and onto the Waterville Plateau overnight. Along with sunny skies Saturday, look for west winds 10-20 mph with afternoon high temperatures in the mid 80’s.
Sunday through Wednesday of next week appears to be relatively quiet and dry with a progressive zonal flow aloft. Northcentral Washington can expect temperatures around normal for this time of year in the upper 80’s to near 90 degrees possibly warming up to a bit above normal by Wednesday. Through this period some breeziness near the Cascade gaps can be expected each evening but no significant weather and mostly clear skies are a strong likelihood.
