   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   No thunderstorms are expected across the U.S. through tonight.

   ...Synopsis...
   Another surge of cold air is anticipated across the CONUS,
   reinforcing the polar airmass already in place. This will result in
   a maintenance of dry and stable conditions, with no thunderstorms
   anticipated. 

   Some deeper convection is possible late tonight/early tomorrow along
   the middle/upper TX Coast as warm-air advection strengthens
   throughout the warm sector of surface low developing over the
   western Gulf of Mexico. Model forecast soundings have thermodynamic
   profiles with scant (and shallow) buoyancy between around 800 to 500
   mb. These profiles also suggest sleet will be the predominant
   precipitation type, with mixed-phase parcels combining with the
   modest buoyancy to support a few lightning flashes. Even so, the
   overall thunderstorm probabilities are still expected to be less
   than 10 percent.
