   Day 3 Convective Outlook  
   NWS Storm Prediction Center Norman OK
   0124 AM CST Sun Jan 20 2019

   Valid 221200Z - 231200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Only isolated weak thunderstorms are possible Tuesday night across
   parts of Louisiana and southern Mississippi.

   ...Synopsis...
   Low pressure will move rapidly northeast from KS into lower MI on
   Tuesday as a large upper trough develops across the Plains. At the
   surface, high pressure will shift off the East Coast allowing for
   minimal low-level moisture return over the Gulf of Mexico. Lower 60s
   F dewpoints will move inland as far north as southern MS Tuesday
   night ahead of a cold front which will support an increasing threat
   of precipitation. Instability will be very weak, and mostly
   offshore, but a few weak storms may develop over LA and into
   southern MS overnight. With such weak instability, severe weather is
   unlikely despite increasing shear.
