A cold front is currently moving through the state, which will bring us periodic breezy conditions and a slight cooling trend. We will see sunny skies today with southwest winds 5-15 mph and afternoon high temperatures in the upper 70’s. Heading into our upcoming weekend, Saturday we will see a second weather system begin to move into Western Washington. We will enjoy mostly sunny skies for much of the day before the front moves into Northcentral Washington late in the day bringing increasing clouds. As the front moves in, we could see west winds pick up 10-20 mph with high temperatures Saturday in the low 70’s.

By Saturday night, a low-pressure system will move north through Oregon and set up a convergence zone over the northern mountains of Washington. While the moisture is not overly deep, there will be a good chance for rain and snow showers for the Cascades and along the Canadian border Saturday night. These showers will sag south overnight, and it now looks like there will be a chance for rain to drop as far south as the Columbia River and north of Highway 2. We have a 20% chance of widely scattered rain showers Saturday night and early Sunday morning.

The front will push back to the north Sunday evening and highs on Sunday will only be in the mid 60’s. By Monday, temperatures will rebound back into the 60’s and lower 70’s under mostly sunny skies.

The upper trough will linger over the area through Thursday of next week with partly cloudy skies, a chance for isolated showers Wednesday night and high temperatures in the upper 60’s.
