Our weather forecast today and Friday will feature a weak “dirty ridge” pattern featuring a generally dry and stable lower atmosphere with slugs of high-altitude moisture promoting fields of cirrus clouds from time to time filtering the sun by day and a waxing crescent moon by night.

Northcentral Washington will see mostly sunny skies both Thursday and Friday with unseasonably warm temperatures into the middle and upper 50’s to near 60 degrees in the Columbia Basin.

By Saturday, weather models are in good agreement overall with the flow featuring a somewhat active and progressive series of waves and ridges. The Wenatchee Valley on Saturday will see mostly cloudy skies and a 20% chance of morning showers with afternoon highs cooling back into the upper 40’s. Saturday will also be quite breezy as cooler air spills over the cascades behind this front with some gust potential to 35-40 mph across the exposed terrain of the Columbia Basin.

Sunday looks like a ridge day for drying and calming weather in the wake of Saturday`s weak storm system. Mostly sunny to partly cloudy skies is expected Sunday with light wind and afternoon highs around 50 degrees.

Monday and Tuesday will feature a moist zonal northwest flow off the Pacific with a 30% chance of rain on Monday and a 30% chance on Tuesday as well, afternoon high temperatures will be in the lower 50’s. Then, back to sunshine for Wednesday’s weather with highs in the lower 50’s.
