AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 1021 PM EDT MON JUL 20 2015 .UPDATE... THE AVIATION SECTION HAS BEEN UPDATED BELOW. && .SYNOPSIS... ISSUED AT 314 PM EDT MON JUL 20 2015 A FRONTAL ZONE ACROSS THE REGION TODAY MAY SERVE AS FOCUS FOR THE DEVELOPMENT OF THUNDERSTORMS THROUGH EARLY TONIGHT...ESPECIALLY ACROSS THE SOUTHERN PORTIONS OF CENTRAL INDIANA. AN ISOLATED STRONG TO SEVERE STORM CANNOT BE RULED OUT. AS THIS FRONTAL ZONE SHIFTS SOUTHWARD...THE STORM THREAT WILL COME TO AN END BY TUESDAY MORNING AND A WELCOME DRY RESPITE WILL OVERSPREAD THE AREA AS HIGH PRESSURE BUILDS INTO THE REGION. && .NEAR TERM /REST OF TONIGHT/... ISSUED AT 946 PM EDT MON JUL 20 2015 SHOWERS AND THUNDERSTORMS CONTINUE TO MOVE ACROSS THE AREA AHEAD OF AN UPPER WAVE. HAVE THUS UPPED POPS MOST LOCATIONS...WITH MANY AREAS NOW IN THE LIKELY CATEGORY THIS EVENING. EXCEPTION WILL BE FAR NORTHEAST FORECAST AREA WHICH LOOKS TO AVOID MOST FORCING. WILL CONTINUE CHANCE POPS THERE. ADDITIONAL SCATTERED CONVECTION HAS DEVELOPED ALONG A COLD FRONT BACK ACROSS NORTHWEST ILLINOIS. SUBSIDENCE BEHIND UPPER WAVE AND TURNED OVER ATMOSPHERE FROM CURRENT CONVECTION SHOULD HELP WEAKEN THIS CONVECTION AS IT MOVES SOUTHEAST. RAPID REFRESH BACKS THIS THINKING UP AS IT DRIES THINGS OUT OVERNIGHT. THUS CONTINUED WITH PREVIOUS FORECAST OF ENDING POPS NORTH OVERNIGHT AND GOING LOWER CHANCES SOUTH. ONLY MADE MINOR ADJUSTMENTS TO TEMPERATURES. && .SHORT TERM /TUESDAY THROUGH THURSDAY/... ISSUED AT 314 PM EDT MON JUL 20 2015 THIS PERIOD SHOULD MAKE CENTRAL INDIANA FEEL MUCH MORE COMFORTABLE COMPARED TO THE HEAT AND HUMIDITY EXPERIENCED OVER THE WEEKEND. CONTINUED TO GO WITH A DRY FORECAST BY TUESDAY MORNING AS HIGH PRESSURE WILL ALLOW FOR A DRY FORECAST THROUGH THE REMAINDER OF THE SHORT TERM PERIOD. GENERALLY AGREED WITH PREVIOUS FORECAST THINKING WITH TEMPERATURES. CONSENSUS NUMBERS APPEAR GENERALLY GOOD IN THE WAKE OF THE FRONT. HOWEVER DID BUMP MAXES UP SLIGHTLY AS MOSTLY SUNNY SKIES ARE EXPECTED...AND ALSO INCREASED LOWS AS THE VERY MOIST GROUND MAY WORK AGAINST DRIER DEWPOINTS AND WORK AGAINST ALLOWING TEMPERATURES TO GET TOO LOW AT NIGHT. && .LONG TERM /THURSDAY NIGHT THROUGH MONDAY/... ISSUED AT 314 PM EDT MON JUL 20 2015 WEAK HIGH PRESSURE OVER THE EASTERN GREAT LAKES AND OHIO WILL DOMINATE OUR WEATHER FRIDAY AND ANOTHER HIGH PRESSURE WILL BUILD IN FROM THE NORTHWEST EARLY NEXT WEEK. IN BETWEEN A VERY WEAK COLD FRONT WILL MOVE ACROSS OUR REGION AROUND SATURDAY NIGHT. WILL MENTION A FEW THUNDERSTORMS BEGINNING LATE SATURDAY OVER THE REST OF THE WEEKEND AND IN THE SOUTH ON MONDAY. POPS WILL BE MAINLY IN THE 20 TO 30 PERCENT RANGE. TEMPERATURES WILL BE SLIGHTLY BELOW NORMAL FRIDAY AND NEAR NORMAL REST OF THE LONG TERM. && .AVIATION /DISCUSSION FOR THE 210300Z KIND TAF UPDATE/... ISSUED AT 1021 PM EDT MON JUL 20 2015 SMALL CONVECTIVE CLUSTER OFF TO THE WEST/NORTHWEST EXPECTED TO IMPACT KIND TOWARDS 210300Z. CLUSTER IS SMALL ENOUGH THAT IMPACTS SHOULD LAST ONLY A HOUR OR TWO. PREVIOUS DISCUSSION FOLLOWS. VORTICITY CENTER DRIFTING EAST OUT OF ILLINOIS DURING THE EVENING HOURS MAY RESULT IN SCATTERED CONVECTION IN THE VICINITY OF THE TERMINALS THROUGH ABOUT 210400Z. NOT SURE AT THIS TIME IF COVERAGE WILL BE ENOUGH FOR DIRECT IMPACTS...BUT WILL MONITOR RADAR/MODEL TRENDS UP TIL ISSUANCE TIME. APPEARS THE BEST CHANCE FOR DIRECT IMPACTS AT THIS TIME WILL BE IN THE KHUF/KBMG AREA...CLOSEST TO THE VORTICITY CENTER. BRIEF IFR VISIBILITY RESTRICTIONS EXPECTED WITH THE HEAVIER PRECIPITATION AREAS. CB BASES AROUND 030. DRIER AIR WILL BE ADVECTING INTO THE AREA LATER TONIGHT...SO DON/T THINK THERE IS MUCH FOG POTENTIAL TONIGHT. SURFACE WINDS GENERALLY AT OR BELOW 7 KTS THROUGH THE NIGHT. && .IND WATCHES/WARNINGS/ADVISORIES... NONE. && SYNOPSIS...SMF NEAR TERM...50 SHORT TERM...SMF LONG TERM....JEH AVIATION...JAS
