Our weather today will feature an area of low pressure spinning off the Washington Coast that will begin to fill and drift into Southwestern British Columbia later this afternoon. The main impacts from this system so far has been a batch of midlevel clouds that is currently passing through Northcentral Washington. This has kept temperatures from completely bottoming out overnight and many locations are running 10 to 15 degrees warmer than this time yesterday. Today will generally be a dry day across a majority of the region with a mix of sun and clouds with afternoon high temperatures in the upper 20’s.

Tonight through Wednesday night, the next bout of snow will affect our area as another weather system drops into Western Washington and draws in a rich moisture fetch currently over Oregon. Unlike our last 3-5 storm systems, this one will feature a punch of warmer air and could bring the potential for a wintry mix across parts of Eastern Washington. There is a 60% chance of snow late tonight and a 70% chance of snow on Wednesday. High temperatures tomorrow will reach the mid-30’s. General snow accumulations in the Wenatchee Valley should be around 1-3 inches with locally around 4-5 inches possible on the Waterville Plateau and northward toward Omak and Twisp.

By Wednesday night, an offshore low wobbles inland and ushers in a relatively strong cold front through Northcentral Washington. This will bring the second wave of very light precipitation with a 40% chance of snow Wednesday night.

The cold front moves east early Thursday morning, under mostly sunny skies and a warmer flow of air, we will see afternoon highs in the mid to upper 30’s.

By Friday, expect patchy morning fog to begin the day with partly cloudy skies by afternoon with afternoon high temperatures in the mid to upper 30’s.

Over the weekend, an upper ridge moves in but temperatures will still run 10 to 20 degrees below normal. Under mostly sunny skies on Saturday and Sunday, we will see highs in the lower to mid-30’s. Normal high temperature for this time of year is 49 degrees. Late Monday the next weather system approaches from the northwest with a chance of snow and cooler temperatures
