Most of the storms remained north of Interstate 70, producing wind damage. Several tents at the Howard County Fair in Kokomo collapsed from strong winds, causing one minor injury.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 1015 AM EDT WED JUL 10 2013 .UPDATE... THE AVIATION SECTION HAS BEEN UPDATED BELOW && .SYNOPSIS... ISSUED AT 145 AM EDT WED JUL 10 2013 SCATTERED TO NUMEROUS THUNDERSTORMS ARE EXPECTED TODAY AND THIS EVENING AS A COLD FRONT DROPS SOUTHEAST ACROSS CENTRAL INDIANA AND INTERACTS WITH VERY WARM...MOIST AND UNSTABLE AIR. THEN...DRY WEATHER IS EXPECTED THURSDAY THROUGH EARLY NEXT WEEK AS AN UPPER RIDGE BUILDS IN. TEMPERATURES WILL BE IN THE UPPER 80S TO LOWER 90S TODAY WITH HIGH HUMIDITY. THEN...THURSDAY THROUGH SATURDAY WILL BE SLIGHTLY BELOW NORMAL WITH LOWER HUMIDITY AND AFTERNOON HIGHS IN THE LOWER TO MID 80S. FINALLY...LATE IN THE WEEKEND AND EARLY NEXT WEEK TEMPERATURES WILL RETURN TO NORMAL IN THE MID 80S TO AROUND 90 AS THE RIDGE BECOMES MORE ESTABLISHED. && .NEAR TERM /TODAY AND TONIGHT/... ISSUED AT 1002 AM EDT WED JUL 10 2013 14Z UPDATE...SCATTERED SHOWERS AND THUNDERSTORMS...A FEW ISOLATED SEVERE...ARE CURRENTLY ON THE RADAR MOSAIC ACROSS MUCH OF CENTRAL AND SRN ILLINOIS. AS THIS ACTIVITY IS PUSHING VERY QUICKLY E/SE WARD AND NEARING THE IL/IN STATE LINE...HAVE BEEFED UP POPS FOR THE NEXT FEW HOURS BEFORE THE FROPA THIS AFTERNOON. PART OF THE FRONT LIES ACROSS CENTRAL IL AND IS MOVING RAPIDLY SE AT THIS HOUR. SPC UPDATED THE SLIGHT RISK TO ENCOMPASS THE ENTIRE CWA...RATHER THAN JUST THE SRN 2/3 BASED ON THIS RADAR TREND. BULK OF THE THE ACTIVITY IS STILL SUB-SEVERE...BUT AS IT CROSSES THE STATE LINE AND ENTERS AN EVEN MORE UNSTABLE ATMOSPHERE...WITH THE FRONT LATER INTERACT WITH IT...EXPECT STORMS TO INCREASE IN COVERAGE AND STRENGTH. PREVIOUS DISCUSSION FOLLOWS... MAIN CHALLENGE TO THE NEAR TERM WILL BE TIMING OF COLD FRONT ACROSS CENTRAL INDIANA AND RESULTANT THUNDERSTORM CHANCES. COLD FRONT WAS CURRENTLY FROM THE UPPER PENINSULA OF MICHIGAN SOUTHWEST TO SOUTHERN IOWA. MODELS...ESPECIALLY THE 00Z GFS AND 21Z SREF...ARE NOW MUCH QUICKER TO BRING THE FRONT SOUTHEAST ACROSS THE FORECAST AREA AS STRONG CANADIAN TROUGH PIVOTS ACROSS NORTHERN ONTARIO. THE OTHER DETERMINISTIC MODELS ARE PRETTY CLOSE IN BRINGING THE FRONT TO JUST SOUTH OF A FORT WAYNE TO LAFAYETTE LINE AT 18Z AND TO OUR SOUTHERNMOST TIER OF COUNTIES BY 00Z. MODELS INCLUDING SOUNDINGS ALL ARE INDICATING A BAND OF MIXED LAYER CAPES OVER 3000 J/KG JUST AHEAD OF THE COLD FRONT AS COOLING MID LEVEL LAPSE RATES INTERACT WITH THE SOUPY AIRMASS. MEANWHILE...75 PLUS UPPER LEVEL JET STREAK ACROSS THE LOWER GREAT LAKES WILL RESULT IN UPPER LEVEL DIVERGENCE ACROSS CENTRAL INDIANA. ALTHOUGH...THERE WILL ONLY BE MARGINAL UNI-DIRECTIONAL SHEAR...DEGREE OF INSTABILITY AND UPPER JET STREAK COULD RESULT IN AT LEAST A FEW SEVERE STORMS THIS AFTERNOON AND EARLY EVENING PER SPC DAY1 OUTLOOK. DAMAGING WINDS WILL BE THE MAIN THREAT. WITH PRECIPITABLE WATER REMAINING AROUND 2 INCHES...HEAVY RAIN WILL ALSO BE A CONCERN. WITH HIGH CONVECTIVE TEMPERATURES...THE STORMS MAY NOT GET GOING TIL THE FRONT IS SOUTH OF OUR NORTHWESTERN COUNTIES...SO WILL GO WITH LOWEST POPS THERE WITH THE HIGHEST SOUTHEAST. WILL HOLD ON TO SMALL CHANCE POPS AFTER 00Z...AND THEN DRY AFTER 06Z AS THE FRONT SETTLES SOUTH OF THE OHIO RIVER AND DRIER AIR MOVES IN AS BROAD SURFACE HIGH PRESSURE SETTLES IN. COULD STILL BE SOME LINGERING CLOUDS AS UPPER TROUGH PIVOTS SOUTH ACROSS SOUTHERN ONTARIO WITH CYCLONIC FLOW ACROSS THE FORECAST AREA. MOS TEMPERATURES CLOSE TODAY AND APPEAR REASONABLE. TONIGHT...PREFER CLOSER TO THE NOT AS COOL 00Z NAM MOS AS CLOUDS THERE SHOULD BE SOME CLOUDS LINGERING AROUND. && .SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/... ISSUED AT 145 AM EDT WED JUL 10 2013 MODELS IN DECENT AGREEMENT ON UPPER RIDGE ACROSS THE FOUR CORNERS EXPANDING NORTHEAST TOWARD THE GREAT LAKES BY FRIDAY NIGHT AS SURFACE HIGH PRESSURE MOVES FROM THE UPPER MIDWEST TO THE LOWER GREAT LAKES AND THEN TO THE ADIRONDACKS. MODEL TIME SECTIONS WERE SHOWING VERY DRY ATMOSPHERE EXCEPT SOME LEFT OVER LOW LEVEL MOISTURE. THIS SHOULD RESULT IN LITTLE CLOUD COVER EXCEPT PERHAPS ON THURSDAY WHEN THE UPPER TROUGH DIVES SOUTH ACROSS THE EASTERN GREAT LAKES AND UPPER OHIO VALLEY. EVEN THEN...SHOULD STILL SEE SOME SUNSHINE. WILL GO COOLER THAN MOS FOR DAYTIME HIGHS AS 850 MILLIBAR TEMPERATURES DROP TO 12 TO 13 DEGREES. NIGHTTIME LOWS SIMILAR FROM MOS AND LOOK OK. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... ISSUED AT 301 AM EDT WED JUL 10 2013 LATEST INITIALIZATION IS KEEPING ENTIRE EXTENDED PERIOD DRY... AND WILL NOT DEVIATE FROM THAT AT THIS TIME. BROAD RIDGE OF HIGH PRESSURE WILL BE ANCHORED OVER MUCH OF THE GREAT LAKES AND OHIO VALLEY REGIONS. THE ONLY CAVEAT WOULD BE SOME PRECIP OVER THE SOUTHEAST QUADRANT OF FORECAST AREA AT THE BEGINNING OF NEXT WEEK AS AN UPPER LOW RETROGRADES FROM THE NORTHEAST U.S. TO THE TENNESSEE VALLEY. COOLER EASTERLY FLOW WILL RESULT IN HIGH TEMPS IN THE LOW TO MID 80S AT THE BEGINNING OF THE LONG TERM...BUT AS FLOW BECOMES MORE SOUTHERLY LATER IN THE PERIOD...HIGHS WILL START APPROACHING THE MID TO UPPER 80S. THE SAME TREND WILL BE TRUE FOR THE OVERNIGHT LOWS...MID 60S IN THE BEGINNING OF THE LONG TERM PERIOD...AND LOW 70S BY THE END OF PERIOD. && .AVIATION /DISCUSSION FOR 1500Z TAF UPDATE/... ISSUED AT 1015 AM EDT WED JUL 10 2013 VERY LOW CERTAINTY INTO AFTERNOON. NUMEROUS THUNDERSTORMS PRODUCING BRIEF IFR VISIBILITIES AND MVFR CEILINGS...ALONG WITH GUSTY WINDS. DRIER AIR WILL QUICKLY FILTER INTO TAF SITES AFTER THU 03Z. AT THAT TIME...ALL TAF SITES WILL DEFINITELY BE AT VFR CATEGORY AND REMAIN THAT WAY FOR THE REMAINDER OF TAF PERIOD. WINDS WILL COME AROUND TO THE NORTHEAST AROUND 10 KNOTS POST COLD FRONT THIS EVENING. && .IND WATCHES/WARNINGS/ADVISORIES...
