Partly cloudy skies in our weather forecast for Friday as a cold front nears the Pacific coast. Northcentral Washington will also see light winds with afternoon high temperatures today generally in the mid 80’s. The Inland Northwest will also be dry with increasing mid to high level clouds throughout the afternoon. The incoming weather system will increase winds through the day, with the most notable increases near the Cascade gaps where west winds are projected to be between 10-15 mph.
By Saturday, the cold front skims through the Wenatchee Valley with the jet crossing the Inland Northwest. Drier air comes with it allowing for a decrease in clouds. Winds will increase through the late morning to afternoon, peaking around the 2:00 to 8:00 p.m. time frame before starting to subside. Speeds of 10-20 mph will be common across the Cascades, Waterville Plateau, Wenatchee Valley and Columbia Basin with gusts possibly around 30 mph. Potential impacts include elevated fire weather concerns and choppy conditions on area bodies of water.
On Sunday, an onshore weather flow will continue albeit substantially weaker than Saturday, as a deep marine layer hugs the Washington State Coast. This is all in response to an upper level trough sagging over the Pacific Northwest. Expect sunny skies Sunday, light winds and afternoon highs cooler than normal around 80 degrees.
Monday through next Thursday, a warming trend begins for the Pacific Northwest as high pressure builds in. In addition to the warming temperatures, the air mass will be rather stagnant so not expecting much in terms of wind either. As we go throughout next week, the atmosphere will warm an additional degree or two each day as we bake under the late August sun. Under sunny skies expect afternoon high temperatures next week in the lower to mid-90’s with overnight lows in the lower to mid-60’s.
