..no severe thunderstorm areas forecast... 


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


... 
Low pressure will move rapidly northeast from Kansas into lower Michigan 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.
