MEANWHILE ADDITIONAL SHOWERS AND THUNDERSTORMS ARE DEVELOPING BACK IN ILLINOIS AHEAD OF THE COLD FRONT. STRONG SHEAR IS ACROSS THE AREA BUT INSTABILITY IS RELATIVELY SMALL DUE TO CLOUD COVER. THERE ARE SOME BREAKS IN THE CLOUDS ACROSS SOUTHERN ILLINOIS AND SOME WARM ADVECTION COULD BRING IN ADDITIONAL INSTABILITY. THUS EXPECT SEVERE THREAT TO CONTINUE THIS EVENING. PLENTIFUL MOISTURE REMAINS ACROSS THE AREA WITH PRECIPITABLE WATER VALUES OVER 2 INCHES. STORMS ARE MOVING QUICKLY ENOUGH THAT FLOODING HAS NOT DEVELOPED YET...BUT WITH ADDITIONAL STORMS MOVING IN WITH THE COLD FRONT HEAVY RAIN AND FLOODING STILL A CONCERN. AS NOTED ABOVE EXPECT ADDITIONAL RAIN TO DEVELOP THIS EVENING AS COLD FRONT APPROACHES AND CENTRAL INDIANA MOVES INTO THE RIGHT REAR QUADRANT OF AN UPPER JET. WENT CATEGORICAL POPS MOST AREAS THIS EVENING. LOWERED POPS OVERNIGHT AS DRIER AIR WORKS IN BEHIND THE FRONT. MODELS SHOW THUNDERSTORMS PRODUCING HEAVY RAIN ACROSS THE SOUTHERN FORECAST AREA TONIGHT WHICH LOOKS REASONABLE GIVEN THE ABOVE. WPC HAS THIS AREA GETTING NEARLY AN INCH AND A HALF IN 6 HOURS...SO FLOODING A CONCERN HERE AS WELL ESPECIALLY GIVEN HILLIER TERRAIN THERE.

NEEDLESS TO SAY...THE MODELS AND ENSEMBLES PAINT A COOL AND DRY PICTURE FOR THE LATE WEEKEND THROUGH THE MIDDLE OF NEXT WEEK WITH WELL BELOW NORMAL TEMPERATURES. WOULD NOT RULE OUT A FEW SHOWERS MONDAY AND MONDAY NIGHT AS A SHARP UPPER TROUGH PIVOTS ACROSS THE GREAT LAKES AND INTERACTS WITH A RIBBON OF MODERATELY DEEPER MOISTURE. OTHERWISE...COOL HIGH PRESSURE AND A DRY COLUMN STRONGLY SUGGEST DRY WEATHER WITH AFTERNOON HIGHS ONLY IN THE 60S TO LOWER 70S AND OVERNIGHT LOWS IN THE 40S AND 50S. && .AVIATION /DISCUSSION FOR THE 102100Z IND TAF UPDATE/...
