ISSUED AT 413 AM EDT TUE AUG 26 2014 A COLD FRONT WILL SLOWLY DRIFT SOUTH OVER THE NEXT 24 HOURS BRINGING ADDITIONAL CHANCES FOR SHOWERS AND THUNDERSTORMS. AHEAD OF THE FRONT...ANOTHER HOT AND HUMID DAY WILL BE IN STORE WITH HIGHS INTO THE UPPER 80S PRIOR TO ANY STORMS. ALONG THE FRONT HIGHS WILL CLIMB INTO THE LOWER 80S AS A RESULT OF INCREASED CLOUD COVER AND RAIN. LOWS TONIGHT WILL DROP INTO THE MIDDLE 60S. && .SHORT TERM...(TODAY AND TONIGHT) ISSUED AT 413 AM EDT TUE AUG 26 2014 BACK EDGE OF DEPARTING WAVE WAS WORKING ACROSS WESTERN PARTS OF THE AREA. IN ITS WAKE...VSBYS WERE RAPIDLY DROPPING WITH VALPARAISO AND KNOX NOW SHOWING AT PATCHY...LOCALLY DENSE FOG. WOULD EXPECTED THIS TREND TO EXPAND EAST AS CLEARING OCCURS. SOME CONCERN THAT DENSE FOG COULD BECOME MORE WIDESPREAD ALONG AND WEST OF ROUTE 15 BUT FOR NOW WILL GO WITH PRE 1ST PERIOD OF PATCHY FOG AND MONITOR. COLD FRONT WILL SLOWLY SAG SOUTH INTO THE REGION TODAY BRINGING ANOTHER SHOT AT SHOWERS AND THUNDERSTORMS. HIGH RES MODELS ALL SUGGEST CONVECTIVE DEVELOPMENT SOMEWHERE FROM CENTRAL ILLINOIS INTO NW PARTS OF THE FORECAST AREA TOWARDS 12Z WITH THIS THEN EXPANDING SE WITH TIME THROUGH LATE AFTERNOON. AS OF WRITING THIS...A FEW CELLS WERE RAPIDLY DEVELOPING IN EASTERN IOWA WHICH COULD BE THE STARTS OF THINGS TO COME. WATER VAPOR LOOP SHOWING SOME INDICATIONS OF A WAVE MOVING ACROSS EASTERN IOWA INTO ILLINOIS THAT COULD GET THINGS MOVING. SPC MESOANALYSIS SHOWING 3500-4000 J/KG OF MOST UNSTABLE CAPE OVER ILLINOIS AND AREAS OF WEAK CONVERGENCE. HAVE ADJUSTED CHANCES FOR PRECIP TO FOCUS MAINLY NW AT THE START OF THE PERIOD BUT HELD IN CHC RANGE FOR NOW. AS THE MORNING PROGRESSES ANY CONVECTION SHOULD EITHER EXPAND OR DEVELOP FURTHER SOUTHEAST WHERE HEATING WILL BE MORE FOCUS AND PRONOUNCED. BY 18Z A SWATH OF MODERATE TO STRONG INSTABILITY SHOULD BE IN PLACE ACROSS SE HALF OF THE AREA WHERE TEMPS SHOULD CLIMB INTO THE UPPER 80S TO NEAR 90. AS HAS BEEN THE CASE...SHEAR PROFILES RATHER ANEMIC LENDING TO SLOW MOVING STORMS CAPABLE OF HEAVY RAIN AND MAYBE AN ISOLATED STRONG WIND GUST AS STORMS COLLAPSE. FRONT SHOULD RESIDE ACROSS THE SOUTHERN COUNTIES THIS EVENING AND THEN STALL OUT. MODELS HAD HINTED AT ADDITIONAL STORMS DEVELOPING OVERNIGHT BUT NOT SURE EXACTLY WHERE BEST CONVERGENCE WILL EXIST SO WILL DOWN PLAY SOMEWHAT AND KEEP IN SLGT CHC TO CHC RANGE. && .LONG TERM...(WEDNESDAY THROUGH MONDAY) ISSUED AT 413 AM EDT TUE AUG 26 2014 CDFNT OVER WI/IA THIS MORNING IS EXPECTED TO BECOME MORE E-W ORIENTED AND MOVE TO JUST SOUTH OF OUR CWA BY WED MORNING. A FEW POST FRONTAL SHOWERS/TSTMS STILL PSBL WED AS A SHRTWV CURRENTLY OVER SASK/MT DROPS SE ACROSS THE GRTLKS.

SFC RIDGE CROSSING THE CWA SHOULD PROVIDE DRY CONDITIONS WED NIGHT. RADIATIONAL COOLING MAY BE LIMITED SOME BY HIGH CLOUDS SPILLING E-SE FROM CONVECTION OVER THE PLAINS IN RESPONSE TO CUT-OFF LOW CROSSING THE ROCKIES... THUS LOWS ONLY EXPECTED TO FALL INTO THE U50S NE TO THE M60S SW. ROCKIES UPR LOW WILL SHEAR OUT TO AN OPEN WAVE OVER THE HIGH PLAINS THU-THU NGT.
