...Heavy snow downwind of the Great Lakes...

...Freeze warnings in effect for portions of southern Georgia down to
central Florida...


Rounds of shortwave energy rotating around the base of an upper low
centered over Hudson Bay will generate frigid and gusty westerly flow over
the Great Lakes today and Tuesday. Lake effect snow showers are expected
to develop downwind of the lakes as a result. Generally, accumulations of
around 8-12 inches are likely with isolated higher amounts possible by
Wednesday morning. High temperatures in the single digits to below zero
will be 20-30 degrees below average for much of the Midwest today. Clear
skies across the Southeast will contribute to below average temperatures
overnight. Low temperatures in the low to mid 30s support freeze warnings
for portions of southern Georgia into northern and central Florida early
this morning and tonight.

Elsewhere, upper ridging will keep temperatures above average in the West
this week. An upper disturbance will bring another round of snow showers
to the Northern Plains and Upper Midwest on Tuesday.
