SCATTERED SHOWER AND THUNDERSTORM ACTIVITY IS EXPECTED TO CONTINUE FOR THE REST OF THE AFTERNOON AND INTO THE EVENING HOURS OVER THE SOUTHERN ZONES ALONG AND AHEAD OF FRONT. MODEL DATA SUGGEST THIS FRONT WILL STALL OUT OVER THE SOUTHERN ZONES LATER TONIGHT. A LOW LEVEL JET...ON THE ORDER OF AROUND 25 KTS...IS EXPECTED TO BEGIN NOSING INTO SOUTHWEST INDIANA AFTER 170600Z. THE INTERACTION OF THIS JET WITH THE FRONTAL SYSTEM SHOULD ALLOW FOR ADDITIONAL SHOWER AND THUNDERSTORM DEVELOPMENT DURING THE PRE DAWN HOURS OF WEDNESDAY. LAPSE RATES LOOK QUITE POOR...NEARLY MOIST ADIABATIC...SO LIGHTNING ACTIVITY MAY NOT BE VERY WIDESPREAD. HOWEVER...SYSTEM LOOKS TO BE AN EFFICIENT RAIN PRODUCER WITH MODELS SUGGESTING RATHER STRONG LIFT AROUND DAYBREAK. WILL GO WITH CHANCE POPS THIS EVENING...INCREASING TO HIGH POPS BY THE PRE DAWN HOURS OF WEDNESDAY. HEAVY RAINFALL WILL BE A THREAT GIVEN THE POTENTIAL DEGREE OF LIFT AND HIGH PRECIPITABLE WATER VALUES.

POTENTIAL UPPER DISTURBANCES RIPPLING THROUGH THE FLOW INTERACTING WITH A MOIST AND UNSTABLE AIR MASS SUGGESTS PERIODIC SHOWER AND THUNDERSTORM CHANCES THROUGH FRIDAY.

BASED ON LOW LEVEL THICKNESSES...THE GFS MOS HIGHS ON WEDNESDAY MAY BE A LITTLE TOO WARM. WILL NUDGE THE GUIDANCE HIGHS DOWN A CATEGORY AT THAT TIME. THE REMAINDER OF THE PERIODS LOOK OK FOR NOW. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
