Shreveport sounding shows wintry mix

Tonight's phase two of our winter storm ended up bringing a significant wintry mix.  The precipitation started out as rain and snow.  Then, it shifted into freezing rain and sleet...then, mostly freezing rain.  Accumulations are up close to a half inch in some areas with over 25,000 without electricity across the ArkLaTex.

The 0Z sounding from the Shreveport National Weather Service plotted by Rap Ucar shows a saturated column with most of it below freezing.  The exception is a 5,000 FT layer that resides just above freezing.  With a surface reading below 32 F, freezing rain became the main weather maker tonight.  Some dynamic cooling probably helped produce sleet at times.  Early on, wet bulb cooling or evaporation was good for the rain/snow mix.
