AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 326 AM EDT WED AUG 11 2010 .UPDATE... THE SYNOPSIS...NEAR TERM AND SHORT TERM SECTIONS HAVE BEEN UPDATED BELOW. && .SYNOPSIS... A DIFFUSE FRONTAL BOUNDARY IS EXPECTED TO LINGER ACROSS THE AREA THROUGH THE END OF THE WORK WEEK. A STRONGER COLD FRONT IS EXPECTED TO PUSH THROUGH OVER THE WEEKEND. HIGH PRESSURE WILL THEN BUILD ACROSS THE REGION THROUGH EARLY NEXT WEEK. && .NEAR TERM /TODAY/... FORECAST FOCUS FOR THE NEAR AND SHORT TERM CONTINUES TO BE ON TEMPERATURES AND THUNDERSTORM CHANCES. ANALYSIS AS OF 3 AM THIS MORNING DEPICTS A STALLED FRONTAL BOUNDARY DRAPED ACROSS CENTRAL ILLINOIS AND INDIANA. SHOWER AND THUNDERSTORM ACTIVITY HAS WANED SIGNIFICANTLY OVERNIGHT WITH THE LOSS OF DAYTIME HEATING. MEANWHILE A WEAK UPPER TROUGH POSITIONED OVER THE UPPER MS VALLEY WILL SHIFT EASTWARD THROUGH EARLY TODAY AND WEAKEN AS IT APPROACHES THE GREAT LAKES. THE COLD FRONT WITH THIS FEATURE SHOULD REMAIN TO THE NORTH OF THE FORECAST AREA...KEEPING THE ASSOCIATED SHOWERS AND THUNDERSTORMS GENERALLY OUT OF THE AREA...THOUGH IT IS POSSIBLE SOME OF THIS ACTIVITY MAY CROSS OVER. IN TERMS OF MODEL CONSENSUS THERE SEEMS TO BE BETTER AGREEMENT WITH REGARD TO TEMPERATURES...THE GFS IS NOW ONLY SLIGHTLY WARMER THAN THE NAM. SHOWER/THUNDERSTORM ACTIVITY WILL BE SIMILAR TO TUESDAY...NOT WIDESPREAD IN COVERAGE, VERY HIT OR MISS...BUT HEAVY RAIN IS POSSIBLE IN ANY OF THE TRAINING THUNDERSTORMS AS PWAT'S CONTINUE TO RUN NEAR 2" AND STORM MOTION REMAINS LESS THAN 10 KTS. BASED ON PERSISTENCE LEANED TOWARD THE SLIGHTLY WARMER GFS FOR TEMPS TODAY. BELIEVE THAT DESPITE THE CHANCES FOR THUNDER AND PARTLY SUNNY CLOUD COVER...LLVL THICKNESSES INDICATE WE WILL SEE TEMPS VERY SIMILAR TO WED...LOW 90S NORTH TO UPPER 90S SOUTH. THIS COUPLED WITH HIGH DEWPOINTS IN THE MID 70S WILL ONCE AGAIN PUSH US OVER TO HEAT WARNING/ADVISORY CRITERIA FOR ANOTHER DAY. AN EXCESSIVE HEAT WARNING WAS ISSUED FOR MARION COUNTY AND SOUTHWARD...WITH ADVISORIES FOR THE REST OF THE NORTHERN COUNTIES. && .SHORT TERM /TONIGHT THROUGH FRIDAY NIGHT/... THE AFOREMENTIONED HEAT WARNINGS/ADVISORIES HAVE BEEN CARRIED THROUGH UNTIL THURSDAY EVENING. OVERNIGHT TEMPERATURES ARE NOT EXPECTED TO FALL BELOW THE MID TO UPPER 70S...AGAIN SIMILAR TO TUE NIGHT...AND THICKNESS SCHEMES INDICATE THAT THU WILL BE ALMOST JUST AS HOT AS WED. PRECIP CHANCES LOOK LOWER AS WELL...AS THERE IS LITTLE FORCING WITH THE LINGERING BOUNDARY TO PRODUCE CONVECTION. STILL A LOW CHANCE WILL BE CONTINUE INTO THU AFTERNOON/EVENING. AGAIN THIS IS NOT EXPECTED TO IMPACT THE SOARING TEMPS MUCH. BOUNDARY FINALLY DROPS SOUTH OF THE INDIANA ON FRIDAY, PROVIDING A DRY FORECAST TO THE END OF THE WORK WEEK. HOWEVER...TEMPS CONTINUE TO BE AN ISSUE...ALBEIT NOT QUITE AS HOT/HUMID AS DEW POINTS FALL INTO THE LOW 70S. A HEAT ADVISORY MAY LIKELY BE NEEDED FOR MANY LOCATIONS ON FRIDAY...AND POSSIBLY WARNINGS ACROSS THE FAR SOUTH. && .LONG TERM /SATURDAY THROUGH NEXT TUESDAY/... ENSEMBLE DATA SUGGEST FAIRLY SIGNIFICANT TROUGHING FOR THIS TIME OF YEAR WILL DROP INTO THE NORTHERN PLAINS AND GREAT LAKES OVER THE WEEKEND AND SHOULD LINGER INTO EARLY NEXT WEEK. WILL CONTINUE WITH CHANCE POPS SATURDAY AND SUNDAY AS A COLD FRONT ASSOCIATED WITH THE DEVELOPING UPPER TROUGH WILL BE MOVING THROUGH AT THAT TIME. CONSIDERING THE STRENGTH OF THE UPPER TROUGH...FRONT SHOULD HAVE A GOOD PUSH WITH IT. ENSEMBLE DATA SUGGEST BY MONDAY AND TUESDAY...FRONT SHOULD BE FAR ENOUGH SOUTHEAST OF THE AREA TO END THE RAIN THREAT AS A MORE STABLE AIR MASS FILTERS IN BEHIND THE FRONT. && .AVIATION /110600Z TAFS/... CONDITIONS WILL CONTINUE TO DETERIORATE TO MVFR/IFR CATEGORY OVER THE NEXT SEVERAL HOURS ACROSS KLAF/KHUF/KBMG AS FOG FORMS. HOWEVER...CONFIDENCE IS NOT AS HIGH FOR FOG FORMATION AT KLAF IF CLOUDS INCREASE DUE TO CONVECTION OVER EASTERN ILLINOIS. VFR CONDITIONS WILL RETURN SHORTLY AFTER DAYBREAK AS FOG BURNS OFF. CONFIDENCE WAS HIGH ENOUGH WITH THIS TAF ISSUANCE TO INSERT VCTS ACROSS TAF SITES FOR THIS AFTERNOON AS A WEAK UPPER LEVEL DISTURBANCE PASSES OVER CENTRAL INDIANA. TIME CROSS SECTIONS AND FORECAST SOUNDINGS SHOW A MUCH DRIER ENVIRONMENT ALOFT BY THIS EVENING. SO...EXPECT SKIES TO CLEAR OUT RATHER QUICKLY AFTER ANY AFTERNOON/EVENING CONVECTION...THIS COUPLED WITH LIGHT WINDS AND ANY MOISTURE FROM DIURNAL STORMS WILL MOST LIKELY RESULT IN FOG AGAIN LATE TONIGHT. && .IND WATCHES/WARNINGS/ADVISORIES... EXCESSIVE HEAT WARNING FROM 11 AM THIS MORNING TO 8 PM EDT THURSDAY FOR INZ043>047-051>056-060>065-067>072. HEAT ADVISORY FROM 11 AM THIS MORNING TO 8 PM EDT THURSDAY FOR INZ021-028>031-035>042-048-049-057. && SYNOPSIS...SMF NEAR TERM...SMF SHORT TERM...SMF LONG TERM....JAS AVIATION...TDUD
