...Clipper system to bring light to moderate snow to the Upper Midwest,
Great Lakes and interior Northeast...
...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 Sest 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.
