A calmer weather pattern will feature across the CONUS through mid-week, before a Gulf system spins up on Thursday. Most precipitation will remain relegated to the northern tier states over the next couple of days. A low pressure system will traverse the Northern Plains and Great Lakes through Thursday while bringing light to moderate snow to those areas. Between 3-6 inches of snow is possible for a swath extending from North Dakota to northern Vermont. Isolated areas, particularly downwind of Lake Ontario may see higher amounts due to snow associated with a proceeding frontal boundary. Winds will pick up on the backside of this system over parts of the Northern Plains today. Troughing in the Northwest will continue to produce measurable snowfall for the region's mountains today before quieting down on Wednesday. A low pressure system will arrive over the Pacific Northwest on Thursday morning, bringing yet another round of measurable snow to the mountains. Rain likely over the coast, and inland lower elevations. Warm air will rise into the Central and Southern Plains today out ahead of the Northern Plains/Great Lakes system. High temperatures are likely to be 15-20 degrees above average with some areas in Kansas seeing more anomalous warmth today. This warm airmass is forecast to shift eastward into the East Coast by Wednesday. Cold air will spill out over the Central/Southern Plains from the Rockies on Wednesday and Thursday. High temperatures may fall back into the upper 30s, which would be 20-30 degrees below average, for parts of eastern New Mexico and the Texas Panhandle.
