It will be another weather day of much below average temperatures with afternoon highs only reaching the low to mid 20s for most of the Inland Northwest. Mostly sunny skies to start the day today but expect clouds to increase through the day as a strong low pressure system organizes over British Columbia, afternoon high temperatures in the mid 20’s. Weather models are in good agreement that light snow will develop north of the Canadian border this afternoon and spread into northern counties this evening. By sunrise on Friday, an inch or two of new snow is expected from Republic to Colville to Bonners Ferry. The influx of cloud cover tonight will keep overnight temperatures a bit warmer than this morning with most readings tonight in the teens for the majority of Northcentral Washington.

Expect periods of light snow during the day Friday as the weather system in southern British Columbia drifts south toward Northwest Washington, high temperatures in the mid 20’s. There is an 80% chance of snow Friday afternoon, a 100% chance of snow Friday night and a 100% chance of snow on Saturday. A Winter Weather Watch will go into effect at 4:00 p.m. tomorrow and will run until 4:00 a.m. Sunday. The Okanogan Valley down toward the Wenatchee area has the potential for heavy snow through this time frame where anywhere from 8 to 12 inches of snow could fall. The mountains could see as much as 10-15 inches of snow by Sunday morning. Wind will also be an issue in the Okanogan Valley up to 30 mph, which could cause some significant blowing and drifting snow on Saturday.

On Sunday, the closed low moves inland across Oregon and moves slowly south bringing us just a slight chance of snow showers Sunday morning with mostly cloudy skies by afternoon with high temperatures only around 20 degrees.

Monday through Wednesday next week should be fairly quiet with a slight chance for snow showers on Monday and Tuesday with highs in the lower 20’s. On Wednesday, we will clear out but remain cold with high temperatures in the mid 20’s.
