LARGE SCALE PICTURE: STRONG MID LEVEL TROUGH TO PROGRESS INTO THE PLAINS TODAY...INTO THE MID MS VLY TONIGHT AND SHOULD REACH THE LOWER OH VY AROUND MIDDAY SUNDAY. ATTM SURFACE WARM FRONT IS LOCATED ACROSS N CTRL IL...NRN IN...NRN OH. THIS FEATURE WILL MOVE NORTH INTO THE GRT LAKES AND WEAKEN AS NEW LEE-SIDE CYCLOGENESIS TAKES EFFECT IN THE SOUTHERN PLAINS THIS MORNING...WITH SURFACE LOW MOVING INTO MO/IL VCNTY THIS AFTERNOON. ONE OF THE CHALLENGES FOR TODAY IS HOW MUCH CONVECTION DURING THE DAY...WELL IN ADVANCE OF STRONG SURFACE COLD FRONT PROGD TO SWEEP THROUGH THE FA LATE TONIGHT. VERY MOIST...WARM AND UNSTABLE ATMS TO REMAIN IN PLACE TODAY. AT 07Z SEVERE CONVECTION RUNNING ALONG THE NORTHERNMOST TIER OF INDIANA COUNTIES. EXPECT THIS TO DIMINISH BY DAYBREAK.
