A fairly strong Pacific storm and a cold front is moving through the Northwest and heading into Idaho this afternoon and evening. This storm has much more moisture than the last one, but slightly milder air, which means that while snow may initially fall in the lower valleys this evening, it will likely begin to mix with or change to rain overnight.
WINTER WEATHER ADVISORIES are in effect for higher elevations of eastern Oregon, and throughout the west central, Boise and central mountains of Idaho through 11 a.m. Wednesday. Generally, 3-6" of snow will fall in most of these areas, but local amounts of a foot or more are possible above 7,500 feet. Lower valley areas, below 3,000 feet, which includes most of the Treasure Valley, will see precipitation begin this evening as snow, but amounts will likely remain under an inch before snow levels rise above 3,500 feet later tonight and the snow quickly mixes with and changes to rain. Foothill locations may see 1-3" of snow.
Once the cold front passes on Wednesday morning, there may be a brief period when rain changes back to snow in the lower valleys, but accumulations are not expected to exceed 1/2". By midday Wednesday, skies will begin to clear, with breezy westerly winds 15-25 mph.
Dry weather will continue through Thursday, Friday, and Saturday, except for a slight chance of snow showers Friday night. Temperatures will be in the mid to upper 30's during the day, low to mid 20's at night. By Sunday and Monday, increasing clouds and a chance of rain, possibly mixed with snow at times, with daytime highs into the low 40's.
