A fast-zonal weather flow continues over the state with one system exiting the area this morning as another moves in. A low-level jet aimed at Southeast Washington will continue to promote windy conditions for Northcentral Washington today out of the northwest 15-20 mph by this afternoon with high temperatures today in the lower 60’s.
By tonight, another round of rain and high mountain snow moves into our area into Tuesday morning followed by the threat of high winds Tuesday afternoon and evening.
Tuesday weather calling for a 90% chance of rain Tuesday morning then windy by afternoon with a high wind watch in affect. Winds will be sustained tomorrow afternoon 25-30 mph with possible gusts up to 50 mph, high temperatures once again in the lower 60’s. Accumulating snow of 2-4 inches is likely at Sherman and Loup Loup passes with another 4-8 inches over Washington Pass. Stevens Pass may receive light accumulations before changing over to rain. Elsewhere Tuesday, rain is expected with most locations receiving another quarter to half inch. But first, Wednesday, the region remains in a strong west-northwest flow on the backside of the exciting trof of low pressure. Winds will remain breezy through the day too, with gusts lingering in the 20-25 mph range. The Wenatchee Valley and Columbia Basin transition to a drier weather pattern, with much less wind by the end of the week.
Thursday a ridge of high pressure builds in, allowing winds to diminish and the threat of precipitation to wane altogether. Quiet, warmer weather is in store Thursday through Sunday with mostly sunny to partly cloudy skies, light wind and afternoon high temperatures above normal into the mid and upper 60’s.
