Weather today will feature a cold front which will move across Northcentral Washington bringing the threat of rain and increased winds. Winds will be most notable this afternoon and evening as the leading gust front crosses west to east. This morning the cold front was coming onto the coast and will push inland through the day and evening, before moving to the Idaho Panhandle overnight. This morning the main rain chances will be around the Cascades. This afternoon the risk expands to the Wenatchee Valley through the Western Columbia Basin. Winds will be the second but the more noticeable and potentially more impacting feature of the weather system. Speeds gradually increase through the morning to midday, before a more notable gust front starts to push east from the Cascades into the Columbia Basin through the afternoon (1:00-4:00 pm). Wenatchee Valley wind today will get to around 5-15 mph but much stronger speeds are expected in the Columbia Basin and east into the Spokane areas with gusts up to 30-40 mph. This could lead to some pockets of blowing dust over the Columbia Basin on I-90 late today and into tonight. Wenatchee forecast today calling for increasing clouds, cooler temperatures and a 50% chance of late day showers with afternoon high temperatures in the lower 80’s.

Thursday the weather front continues to shift east however, temperatures will be slightly cooler than normal on the backside of the cold front with highs tomorrow just above 80 degrees.

A nearly zonal weather flow aloft will set up over the Pacific Northwest Friday and continue through the weekend with mostly sunny to sunny skies and afternoon high temperatures in the mid 80’s with overnight lows this weekend around 60 degrees.

By Monday and Tuesday next week, high pressure in the Pacific will begin to amplify with a northwesterly flow over the Inland Northwest bringing sunny skies and warmer temperatures into the mid and upper 80’s with lows in the lower to mid 60’s.
