CONCERNING...WINTER MIXED PRECIPITATION

VALID 110746Z - 111315Z

SUMMARY...FREEZING RAIN...WITH RATES OF 0.05 IN/3 HRS OR MORE...AND
SLEET WILL LIKELY CONTINUE AND INCREASE IN AREAL COVERAGE THROUGH
13Z.

DISCUSSION...PRECIPITATION CONTINUES TO INCREASE WITHIN A BROAD
LOW-LEVEL WARM ADVECTION ZONE ACROSS PORTIONS OF THE LOWER MS/TN
VALLEY REGION AS OF 0730Z. LATEST MESOANALYSIS SHOWS THE WET-BULB
FREEZING LINE EXTENDS FROM SOUTH OF MLU EWD ACROSS CENTRAL MS TO
NORTH OF BHM AND ACROSS FAR NWRN GA. N-NELY LOW-LEVEL FLOW WILL
CONTINUE TO ADVECT DRY AIR ACROSS THE DISCUSSION AREA AND ALLOW THE
FREEZING LINE TO CONTINUE SHIFTING SLOWLY SWD. MORE CONCENTRATED
LIFT RESULTING FROM INCREASING FRONTOGENETICAL FORCING IN THE
850-700 MB LAYER WILL LEAD TO HIGHER PRECIPITATION RATES THROUGH
13Z...AND FORECAST SOUNDINGS SUGGEST FREEZING RAIN AND SLEET WILL BE
DOMINANT PRECIP TYPES WITHIN THE DISCUSSION AREA...WITH SNOW ALSO
POSSIBLE ACROSS NRN PORTIONS OF THE DISCUSSION AREA. FREEZING RAIN
RATES IN EXCESS OF 0.05 INCHES/3 HRS WILL BE LIKELY.
