   AREAS AFFECTED...PORTIONS OF SERN AR...SRN TN...NERN LA...NRN
   MS...NRN AL...NWRN GA

   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.
