A flat upper-level ridge of high pressure will remain over the Northwestern U.S. over the next 48 hours. Shortwaves of moisture riding up the western periphery of the ridge will stay well offshore but help to steer an atmospheric river into Western Washington which at times will bleed over the Cascades and into the Inland Northwest. Northcentral Washington weather today will be cloudy with a 50% chance of freezing rain, highs around 30 degrees. As we go into tonight and early Wednesday morning, the threat for a wintry mix will continue over Central Washington. This is when we will see the richest influx of moisture with continued midlevel warming. I wouldn`t rule out a mix with sleet at times, especially for the Methow Valley across the northern mountain communities.

Wednesday’s weather will be mostly cloudy with just a slight chance for freezing rain and afternoon high temperatures, warmer, into the upper 30’s.

Partly cloudy and mild for Thursday and Friday with afternoon highs in the upper 30’s to near 40 degrees.

Mostly cloudy and slightly cooler weather on Saturday and Sunday with afternoon highs generally in the mid to upper 30’s.

A ridge of high pressure will remain over the area on Monday as well brining partly cloudy skies and afternoon high temperatures in the upper 30’s.
