Wind will once again be our main weather feature today as a very strong jet stream barrels across Northcentral Washington. It will begin to sag south late tonight and should be out of the region by Friday night. Drier air has also moved in and the best chance for showers today will be along the crest of the Cascades and Idaho Panhandle. Forecast challenge for today will be the wind speeds and gusts. Widespread 20-25 mph wind speeds are expected across the Waterville Plateau into the Columbia Basin and Wenatchee Valley. Some locally higher winds up to 30 mph are possible around Wenatchee and portions of the Waterville Plateau. Gusts will be 25 to 35 with some locally higher gusts 45 to 50 mph. A red flag warning has been issued for portions of the Waterville Plateau, Columbia Basin and Wenatchee Valley for this afternoon/evening from 2:00 p.m. to 8:00 p.m. Under sunny skies today, Wenatchee valley high temperatures should top out in the upper 70’s, which is over 10 degrees below normal.
The clear skies tonight and dry air still punching into our area, will lead to a very chilly morning for much of the Cascades and the typically colder valleys across northern Washington. Any outdoor enthusiasts in the Cascade Mountains can expect lows in the 30s while most of Northcentral Washington will see overnight lows in the lower 50’s.
On Friday, we can expect sunny skies and continued breezy conditions out of the northwest between 10-15 mph with gusts to 25 mph, highs in the upper 70’s.
The weather for the weekend looks dry as the cool trough currently over our region shears east toward the Great Lakes. Under sunny skies, high temperatures on Saturday will likely rebound into the mid-80s over most of central and eastern Washington. Sunday weather will warm up even more into the upper 80s to low 90s for the majority of Northcentral Washington.
Monday through Wednesday, weather models continue to forecast above average temperatures early next week into midweek. There is good agreement that a highly amplified ridge of high-pressure weather pattern will develop over North America. By Monday, strong high pressure will be centered over the Rockies with a broad upper low off the coast of British Columbia. At this time, it looks like Monday and Tuesday will be the hottest days of the week before the offshore low pivots inland Tuesday night or Wednesday. High temperatures early next week will be in the lower to mid-90’s.
