   Areas affected...Louisiana into Mississippi and northern Alabama

   Concerning...Winter mixed precipitation 

   Valid 151717Z - 152115Z

   SUMMARY...A wintry mix of snow, sleet, and freezing rain is expected
   to spread east from southeast Arkansas and northern Louisiana into
   Mississippi and northern Alabama through early afternoon.

   DISCUSSION...Surface observations, LSRs, and MPING reports over the
   past 1-2 hours continue to show a mix of snow, sleet, and freezing
   rain from the ArkLaTex region into northern MS/AL within a broad
   precipitation swath. Isentropic ascent over a 925-850 mb frontal
   zone is forecast to persist through early afternoon as a
   low-amplitude wave, currently over the southern Plains, migrates
   east. Recent sleet LSRs and forecast soundings suggest that a mix of
   snow and sleet will be more likely where surface temperatures are in
   the low 20s or lower. Areas where temperatures are in the mid-20s or
   higher should have too shallow/warm of a sub-freezing layer to
   support much re-freezing of hydrometeors, making a sleet/freezing
   rain mix more probable. Forecast guidance suggests that
   precipitation intensity may gradually wane heading into the
   mid-afternoon hours, but a zone of impactful wintry precipitation
   appears probable prior to this occurring.
