WEAK COLD FRONT DRAPED ACROSS THE CAE CWA IS PROVIDING A FOCUSING MECHANISM FOR SHOWERS AND THUNDERSTORMS TO DEVELOP. WEAK VORTICITY TROUGH OVER MAINLY THE SOUTHERN PART OF THE CWA. ATMOSPHERE PRETTY UNSTABLE WITH LIS -8...CAPES 3000-4000...KIS >30...AND PWS > 2 INCHES. ALSO GOOD MODEL OMEGA DURING THE EVENING HOURS. SOME STRONGER THUNDERSTORMS DEVELOPING WITH VILS > 40.

WEAK CONVERGENCE ASSOCIATED WITH THE NEARBY FRONT...HIGH MOISTURE...AND HEATING WILL HELP CAUSE THUNDERSTORMS THIS AFTERNOON AND EVENING. WARM MID-LEVEL TEMPERATURES WILL LIMIT THUNDERSTORM COVERAGE SO THE CHANCE APPEARS TOO LOW TO FORECAST AT THE TERMINALS AT THIS TIME.
