The next 2 days of weather will focus on an unseasonably very strong upper level Jetstream. A closed low-pressure system will move into Canada late today, with most of the strong dynamics as far as rain remaining north of the border. Today and on Thursday, Northcentral Washington can expect breezy to at times windy conditions across the area with steady winds between 10-15 mph with gusts up to 26 mph, highs in the mid to upper 70’s. Today`s winds will focus more in the Cascades, Wenatchee area, Waterville Plateau into the Columbia Basin, Palouse and Spokane area.

Windy on Thursday as well in the Wenatchee Valley under sunny skies, expect steady wind speeds between 10-20 mph with gusts up to 30 mph with afternoon high temperatures once again below normal in the mid to upper 70’s. Some Northcentral Washington locations will see widespread gusts 25 to 35 mph with brief, locally higher gusts possible between 40 to 50 mph. These winds will raise some fire weather concerns, especially on Thursday as the relative humidity values drop into the upper teens to mid-20s for most of our area. However most fuels are not cured/dried out enough to warrant highlights, as of this morning.

On Friday, our weather will begin to stabilize but as the cold front slowly moves off tho the east we will remain on the cool side Friday with highs once again only in the upper 70’s. Northcentral Washington will also see some chilly overnight lows only in the lower to mid-50’s.

As we move into the weekend, Saturday will be mostly dry as a large area of high pressure builds into the area starting our warm-up for the weekend into next week. So we are drying the forecast Saturday onward and temperatures will finally be above normal come Monday as a more Summer like pattern and high pressure ridge axis set up to the east over Montana with south to southwest flow aloft. Afternoon high temperatures Saturday will warm into the mid 80’s.

On Sunday, expect sunny skies and much warmer temperatures with highs near 90 degrees.

Temperatures will be well into the 90s for the beginning of next week with afternoon high temperatures on both Monday and Tuesday near 95 degrees.
