The weather pattern will be cool and showery across the Inland Northwest today through Saturday. Widely scattered thunderstorms will be possible Friday bringing the potential for brief heavy rain and cloud to ground lightning. A cold front will also move through dropping temperatures to 10 degrees below normal. A warming and drying trend will then begin on Sunday as a large area of high-pressure moves inland off the Pacific coast. Temperatures in the upper 80s to mid-90s are expected Tuesday, Wednesday, and Thursday of next week with record high temperatures possible in many Northcentral Washington locations.
Wenatchee Valley weather forecast for today is calling for partly cloudy skies and windy conditions out of the west 10-20 mph with gusts later on as high as 30 mph, highs today in the upper 60’s.
Even cooler weather is expected on Friday with a 20% chance of showers and windy conditions, highs tomorrow will only top out in the mid 60’s. Winds will also be breezy Friday afternoon with gusts between 25-35 mph across exposed areas of the Columbia Basin, Spokane, the Palouse, as well as the Wenatchee Valley and Waterville Plateau.
The heart of our cool low-pressure trough is forecast to wrap up over Alberta and Saskatchewan on Saturday. Our weather will remain a bit cool for this time of year with afternoon high temperatures under sunny skies expected to top off in the lower 70’s.
By Sunday and Monday, there is good agreement between the medium range weather models that a dry and warmer weather pattern will develop early next week. Under sunny skies, high temperatures on Sunday are expected to be about average with the majority of our lowlands in the mid to upper 70s. With light winds and mostly sunny skies, Sunday will be ideal for most outdoor activities. Monday will be another pleasant day with mostly sunny skies and afternoon high temperatures in the lower to mid-80’s.
Forecast confidence is growing that by the middle of next week, our weather will feature much above average temperatures. Under sunny skies Tuesday, afternoon high temperatures could climb into the lower 90’s with mid 90’s expected on Wednesday under mostly sunny skies.
There is decent weather model agreement that the hot high-pressure ridge will break down Thursday into Friday. A late week cold front has the potential to produce gusty winds and fire weather concerns.
