Areas affected...Far Southeast Louisiana...Far Southern
Mississippi...Far Southern Alabama...Florida Panhandle

Concerning...Heavy snow=20

Valid 212252Z - 220445Z

SUMMARY...Heavy snow will be likely over the next few hours along
parts of the central Gulf Coast from far southeast Louisiana into
the Florida Panhandle and southern Alabama. Snowfall rates are
expected to exceed 1 inch per hour within the heaviest parts of the
band.

DISCUSSION...Water vapor imagery shows a mid-level trough from the
Ohio Valley extending southwestward into the lower Mississippi
Valley. A powerful mid-level jet of 100 to 140 knots is located to
the east of the trough, with the exit region of this jet located in
the central Gulf Coast region. Widespread precipitation is ongoing
beneath this feature (where lift is strong) from far southeast
Louisiana east-northeastward into the Florida Panhandle and southern
Alabama. Most of the precipitation is in the form of snow, with some
reports of heavy snow. The latest model forecasts suggest that a
band of strong isentropic ascent will continue to spread eastward
across the central Gulf Coast region, making conditions favorable
for heavy snow over the next few hours. Snowfall rates are expected
to exceed 1 inch per hour in some locations. The potential for heavy
snow is expected to continue into early to mid evening over southern
Alabama and the Florida Panhandle. Further to the west, snowfall
rates should gradually decrease over parts of far southeast
Louisiana and southern Mississippi.
