Areas affected...northern MS to the southern Appalachians

Concerning...Freezing rain=20

Valid 241817Z - 242345Z

SUMMARY...Freezing rain mixed with sleet is expected to expand
across parts of the Tennessee Valley to the southern Appalachians
through late afternoon. The most likely corridor for appreciable
accretion appears centered on north-central Mississippi, northwest
Alabama, and southeast Tennessee.

DISCUSSION...A broad swath of mixed winter precip is ongoing from
KY/TN southwest to LA. The initial leading activity has largely
remained as sleet and snow, with greater liquid-equivalent rates in
sleet, freezing rain, and rain over LA. This latter plume is
expected to be the most prolific for freezing rain rates as it
shifts northeast through late afternoon. Liquid-equivalent rates of
.05 to .25 in/hr should remain common. Despite ample low-level
isentropic ascent, guidance is quite insistent on expanding the
above-freezing warm nose north-northeast across northern MS to
eastern TN through 00Z. A 15Z UL-Monroe sounding sampled around 12C
at 900 mb, indicative of a classic freezing rain/mixed sleet
profile. The overall setup suggests that these should become the
primary PTYPEs across central/northern MS through northwest AL to
southeast TN.
