Weather across America

(NATIONAL) A clipper system will bring light to moderate snow to the Upper Midwest, Great Lakes, and interior Northeast, and a winter storm will bring heavy snow and strong winds to much of the West, the Northern/Central Plains and Upper Midwest through midweek. 

Shortwave energy riding along the southern periphery of a mean upper trough will bring a quick hit of snow showers to parts of the Upper Midwest/Great Lakes on Monday night before spreading into the Lower Great Lakes and Northeast on Tuesday. Snowfall totals should remain relatively negligible with accumulations of between 3-6 inches, and locally higher amounts, likely across the aforementioned northern tier regions.

A deep upper-level trough will enter the Northwest early this week. Heavy snow and strong winds are expected to across the Cascades and Northern Rockies on Monday before spreading into the Northern Plains on Tuesday. Snow accumulations of around 2-4 feet are possible in the Northwest mountains while portions of the Northern Plains could receive between 3-6 inches with locally higher amounts through Tuesday. Increasing winds may cause blowing snow over parts of the Northern Plains.

The wind threat shifts into the Southwest and Southern Plains late Tuesday into Wednesday as the region gets sandwiched between a digging northern stream trough in the West and a southern stream low gliding across the Baja peninsula. Wind speeds of over 30mph and gusts over 40mph are expected for the Four Corners region. 

An anomalous arctic airmass intrudes into the West mid-to-late week on the backside of the storm system, while much of the Southeast and Mid-Atlantic experience potentially record breaking warm temperatures.
