 A low pressure system that brought snowy and windy conditions to the
central and northern Plains will advance northeastward toward the Great Lakes. This will bring snow showers to the
upper Midwest and Great Lakes throughout the day. Moisture will be limited with this system, so most areas will see 1 to 2 inches of new snow.
Strong winds will accompany this system with gusts between 20 to 30 mph. The southern side of this system will remain in the 40s, thus supporting freezing rain and rain showers across the Midwest. Rainfall accumulation from the
mid-Mississippi River Valley through the Ohio River Valley will be less than half an inch. This fast-moving system will reach into the Northeast late in the evening hours, bringing rain and snow to the region.
In the West, a strong low pressure system spinning in the Gulf of Alaska will continue pushing waves of energy over the Pacific Northwest. Flow from the west continues pulling abundant moisture onshore, allowing for more rain and high-elevation snow showers to develop. Expect another 4 to 8 inches of new snow over Idaho and western Montana, while 9 to 13 inches of new snow are likely across the far northern Washington Cascades.
Rainfall totals at lower elevations and along the coasts will range from 0.50 to 1.0 inches on Tuesday. High pressure to the south will keep most of California dry with mostly sunny skies.
Temperatures in the Lower 48 states Monday ranged from a morning low of
minus 11 degrees at Stanley, Idaho, to a high of 79 degrees at Harlingen, Texas.
