   Areas affected...Northern Louisiana into eastern
   Arkansas...northwest Mississippi...and far western Tennessee

   Concerning...Winter mixed precipitation 

   Valid 250146Z - 250645Z

   SUMMARY...Another round of freezing rain and sleet is expected to
   spread out of northern Louisiana into eastern Arkansas and northwest
   Mississippi. Freezing rain rates upwards of 0.05 inch/hour appear
   likely for some locations.

   DISCUSSION...Recent radar mosaics show a developing plume of
   precipitation across central to northern LA - likely associated with
   strengthening warm advection between 925-850 mb. Over the next
   several hours, an uptick in low-level winds should promote further
   augmentation of isentropic and frontogenetical ascent across the
   lower MS River Valley. Regional 00z RAOBs from SHV and LZK sampled a
   stout (4-12 C) warm layer between 850-700 mb that will melt
   hydrometeors as precipitation spreads north/northeast. Sub-freezing
   surface temperatures will promote some degree of re-freezing near
   the surface, though locations with temperatures at or near/below 15
   F will likely be sufficiently cold (and have a sufficiently deep
   sub-freezing layer) to promote sleet as the predominant
   precipitation type. Warmer locations will likely observe freezing
   rain (with freezing rain rates up to 0.05 inch/hour) with periods of
   sleet possible. Based on latest surface observations, freezing rain
   appears most probable across southeast AR into northwest MS with
   sleet more likely for locations further north into east-central AR
   and far western TN.
