A west and northwest flow continues today with another disturbance moving through today. The middle and lower boundary layers are fairly moist so expect some significant cloud cover at times with some light showers even in the lower valleys between Wenatchee (morning), Moses Lake (late morning) and Pullman/Spokane (afternoon). Northcentral Washington weather today will be partly to mostly cloudy and cool with afternoon highs in the mid to upper 50’s.
A ridge of high pressure will slowly build in on Friday pushing the trough to the east, however, expect cloudy skies tomorrow and a 20% chance of a sprinkle or two with highs around 60 degrees.
Expect partly cloudy skies and warmer temperatures on Saturday with afternoon highs in the mid-60’s.
Sunday we will see an increase in clouds, which will cool our temperatures a couple of degrees as a Gulf of Alaska cold front slides through. Weather Sunday will be cloudy with a 40% chance of afternoon rain, highs in the lower 60’s.
The trough of low pressure and associated cold front exits the region on Monday allowing a shortwave ridge of high pressure to build in. Forecast Monday through Wednesday will be quiet with partly cloudy skies each day, light wind and seasonal highs with temperatures generally in the lower 60’s.
