STEEPER LAPSE RATES AND ASCENT ATTENDING SHORTWAVE TROUGH MOVING SE

THERMODYNAMIC ENVIRONMENT...ANY ADDITIONAL LIGHTNING STRIKES SHOULD
REMAIN SPORADIC AND ISOLATED.

700-500 MB LAPSE RATES WILL CONTINUE TO PROMOTE AREAS OF SCATTERED
CONVECTION OVERNIGHT. HOWEVER...LIMITED INSTABILITY SUGGEST ANY
LIGHTNING STRIKES WILL REMAIN VERY ISOLATED AND SPORADIC WITH
COVERAGE GENERALLY LESS THAN 10%.
