Saturday was an in-between day weather-wise with a distinct frontal boundary separating Oregon and Washington. Snow fell early in the Bellingham area and in the San Juan Islands and Whidbey Island. Temperatures warmed by afternoon, and it was a chilly rain down to Olympia.There’s a threat of snow in the Western Washington lowlands through early Monday but will not include Clark County. Three to 5 inches could fall in the north interior and up to 2 inches on the higher hills in the Seattle area. No snow was expected south of Tacoma. Remember the usual rule: If it snows in Seattle, Portland/Vancouver doesn’t get any, and vice versa.We do see some showers moving in tonight and Monday but no snow. Cold air will filter into the Columbia Basin and down the Columbia River Gorge. That may be one area that gets a wintry mix. But as of this writing that is as close as it comes.Saturday afternoon one could see the line between the milder air mass and the cold air mass at 4 p.m. with Ellensburg in the 30s with light snow and Yakima, a few miles down the road enjoying the mid-40s.Milder Pacific air will keep the modified arctic air from covering us and bring periods of much-needed moisture to California off and on. Ours is a broad-brush type of forecast: partly to mostly cloudy with a chance of rain all week with heaviest amounts tonight and Monday. We stay in the 40s for highs and slowly rise back into the 50s as the week wears on.
