...DISCUSSION...
A large-scale upper trough will shift from the Rockies through the
central and eastern CONUS Days 4-6/Sat-Mon. As this occurs, a very
cold airmass will overspread much of the country, with a swath of
winter precipitation expected to spread from the southern Plains
through the Mid-Atlantic. At the surface, model guidance varies, but
a deepening low is expected to develop over the central Gulf Coast
vicinity on Saturday night/early Sunday. The low and trailing cold
front will move offshore the Atlantic coast by early Monday.
Depending how far north the surface low develops, some thunderstorm
potential could increase across parts of the central Gulf Coast and
the FL Panhandle on Sunday. However, severe storms appear unlikely.
The very cold airmass settling over much of the country during the
weekend is likely to persist into early next week, precluding
thunderstorm potential through the end of the period.
