...Clipper system to bring more snow squalls, high winds, and periods of
heavy snow to the Great Lakes and Northeast tomorrow and Wednesday...

...Periods of moderate to locally heavy rainfall possible over South Texas
today and tomorrow ...

As the prolific lake-effect snowfall from this weekend tapers off tonight,
another round of impactful winter weather is on deck for across portions
of the Upper Midwest, Northeast, and New England as a potent Clipper
system ushers in a cold Arctic airmass. Beginning tomorrow, the passage of
the Arctic cold front will lead to an outbreak of snow squalls containing
intense bursts of snow and gusty winds upwards of 50 mph in the Upper
Midwest and Great Lakes, which spread southeastward into the Central
Appalachians and Northeast by Thursday. Over the lake-effect snow belts,
1-2 feet of snowfall can be expected, with heavy snow also possible across
New England as the Clipper deepens to the north. Users are encouraged to
stay up to date on the latest Key Messages for this event as it unfolds
over the next three days. In the wake of the Clipper and Arctic front,
cold temperatures with highs in the teens to upper 20's are expected
across the Upper Midwest into the Ohio Valley.

Meanwhile, a weak frontal low interacting with Gulf return flow along the
coastline will support moderate to locally heavy rainfall over South Texas
today and tomorrow. While the heaviest rainfall amounts (on the order of
1-3") are forecast to remain offshore, isolated flash flooding is possible
today along a Corpus Christi to Brownsville line should any of the deeper
convection make it inland.
