AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 302 PM EDT WED JUL 28 2010 .UPDATE... THE SYNOPSIS...NEAR TERM...SHORT TERM AND LONG TERM SECTIONS HAVE BEEN UPDATED BELOW. && .SYNOPSIS... WILL ALLOW HEAT ADVISORY TO CONTINUE INTO THIS EVENING THOUGH SCATTERED PRECIPITATION WILL COOL SOME LOCATIONS. HOT AND HUMID CONDITIONS TODAY WILL BE SHORT LIVED AS COLD FRONT USHERS IN SLIGHTLY DRIER AND COOLER AIR THURSDAY AND FRIDAY. STORMS TONIGHT WILL BE SCATTERED FOR MOST PART BUT MORE ORGANIZED LINE OF STORMS WILL BE ASSOCIATED WITH SOUTHWARD MOVING COLD FRONT ENTERING CENTRAL INDIANA TONIGHT. THIS COOL DOWN WILL BE SLIGHT AND SHORT LIVED AS OVERALL LARGE SCALE PATTERN CHANGES LITTLE WITH FREQUENT SHORT WAVES MOVING THROUGH SOUTHERN BRANCH OF WESTERLIES ACROSS SOUTHERN CANADA. EACH WAVE RETURNS SURFACE WINDS TO THE SOUTH...BRINGING HEAT AND HUMIDITY BACK. HIGH PRESSURE BEHIND WEAK COLD FRONTS TONIGHT...SATURDAY NIGHT AND MIDWEEK NEXT WEEK OFFER BRIEF AND SLIGHT RELIEF. NO MAJOR HEAVY RAIN EVENTS EXPECTED AND MAIN ISSUE WITH COMING SEVEN DAY FORECAST CENTERS MORE ON TIMING OF WARM-UPS AND COOL DOWNS AND ASSOCIATED RAIN WITH EACH WARM UP. && .NEAR TERM /TONIGHT/... FORECAST CHALLENGE FOCUSED ON PRECIP TONIGHT. GIVEN SCATTERED SHOWERS AND STORMS PRESENT AT THE MOMENT WILL LEAN TO HIGHER POPS OF MAV MOS. ALL GUIDANCE CLOSE WITH RESPECT TO MIN TEMPS SO AN AVG TO BE USED WITH UPPER 60S NORTH AND LOWER 70S SOUTH STILL ON TARGET. SCATTERED SHOWERS POPPED ON SCHEDULE THIS AFTERNOON AS WE REACHED CONVECTIVE TEMPERATURE AND STILL ONGOING. SHORT WAVE AND JET STREAK CUTTING EAST ACROSS THE GREAT LAKES COMBINED WITH SURFACE FRONT AIDING IN MORE ORGANIZED CONVECTION ACROSS NORTHERN INDIANA AND OHIO. ALL MODELS HAVE BEEN CONSISTENT IN KEEPING MAIN FORCING WELL NORTH AND WITH LOSS OF DAYTIME HEAT AND SUBSEQUENT STABILIZING EXPECT STRONGER STORMS TO OUR NORTH TO WEAKEN AS THE BROKEN E-W LINE SETTLES SOUTH. 500H TEMPS VERY SIMILAR TO LAST SAT NGT AND IN THAT CASE CONVECTION WAS PRESENT BUT SEVERE WAS LIMITED. .SHORT TERM /THURSDAY AND FRIDAY/... HIGH PRESSURE STEADILY BUILDS INTO THE FORECAST AREA THURSDAY. MODELS AGAIN SIMILAR TO SATURDAY IN HANDLING FRONTS POSITION AND LAGGING PRECIP BEHIND IT THURSDAY MORNING. WIND SHIFT AND SURFACE BOUNDARY SHOULD BE SOUTH OF FORECAST AREA BY DAYBREAK AND WITH UPPER SUPPORT WELL EAST...ANY SHOWERS THAT WOULD DEVELOP SHOULD BE SOUTH OF THE EAST FORK WHITE RIVER SO WILL REMOVE ANY PRECIP THREAT FOR FORECAST AREA THURSDAY MORNING. COLD ADVECTION BEHIND THE FRONT AND LEFTOVER LOW LEVEL MOISTURE WILL DEVELOP CUMULUS IN THE MORNING BUT AS DRIER AIR CONTINUES TO BUILD IN...SKIES SHOULD BE CLEAR BEFORE SUNDOWN THURSDAY WITH CLEARS SKIES THURSDAY NIGHT EXCEPT FOR LATE NIGHT CIRRUS SPILLING SOUTHEAST OUT OF MCS CONVECTION OVER MINNESOTA AND IOWA. AGAIN CURRENT TEMPS AND MODEL GUIDANCE PRETTY SIMILAR AND BLENDED. LATEST MODELS CARRY REMNANTS OF THURSDAY NIGHT MCS IN MINNESOTA AND IOWA INTO THE GREAT LAKES INCLUDING OUR AREA. DRY LOW LAYERS WITH CIRRUS SHIELD OVERSPREAD SHOULD MAKE FOR PARTLY CLOUDY BUT RAIN FREE DAY FRIDAY WITH CURRENT FCST TEMPS OF MID AND UPPER 80S ON TARGET. MAIN STORM REDEVELOPMENT FRIDAY NIGHT WILL BE UP IN THE GREAT LAKES BUT RETURN TO SOUTHWEST SURFACE FLOW AND MOISTENING OF BOUNDARY LAYER HERE MAY RESULT IN SOME SHOWERS. ODDS ARE FRIDAY NIGHT TO STAY DRY BUT SEE NO REASON TO REMOVE POPS GIVEN INCREASING MOISTURE AND APPROACHING SURFACE BOUNDARY. && .LONG TERM /SATURDAY THROUGH WEDNESDAY/... FORECAST FOCUS IS ON CHANCES FOR RAIN. MODELS ARE SIMILAR SO WENT WITH A BLEND. BOTH GFS AND EURO SWEEP A WEAK SURFACE TROF ACROSS OUR AREA SATURDAY AND REBUILD HIGH PRESSURE BEHIND IT ACROSS GREAT LAKES SATURDAY NIGHT AND SUNDAY. THUS CONTINUE THE POPS FOR SATURDAY AS CURRENTLY FCST AND KEEP DRY WEATHER SATURDAY NIGHT INTO MONDAY NIGHT WITH SLIGHTLY COOLER TEMPS AND SLIGHTLY LOWER HUMIDITY SIMILAR TO THIS THURSDAY AND FRIDAY. ALL MODELS SIMILAR EARLY NEXT WEEK BRINGING YET ANOTHER SHORTWAVE ACROSS SOUTHERN CANADA WITH APPROACHING SURFACE TROF. PRIMARY PRECIP THREAT ACROSS GREAT LAKES AGAIN BUT TAIL OF TROF DOWN TO LOWER OHIO VALLEY TO BRING AT LEAST SOME PRECIP THREAT. SO OVERALL FOR THE COMING WEEK BRIEF COOL DOWNS AND LOWER HUMIDITY THURSDAY FRIDAY...SUNDAY MONDAY. PERIODS IN BETWEEN WITH LOW CHANCE POPS AND NO WIDESPREAD HEAVY RAINS EXPECTED. COOL DOWNS MEAN HIGH TEMPS IN 80S BUT AHEAD OF WEAK COLD FRONTS EXPECT HIGHS BACK INTO 90S AND DEWPOINTS BACK INTO LOW OR MID 70S. && .AVIATION.../281800Z TAFS/... PO PUP SHOWERS AND THUNDERSTORMS HAVE FORMED OVER MOST OF CENTRAL INDIANA. NONE OF THE TAF SITES ARE REPORTING RAIN/STORMS AT THIS TIME...SO JUST WENT WITH VCSH FOR NOW. ANTICIPATE THUNDERSTORM DEVELOPMENT LATER THIS AFTERNOON...AND CONTINUING INTO THE NIGHT AS COLD FRONT MOVES FROM NORTHWEST TO SOUTHEAST ACROSS CENTRAL INDIANA. AS A RESULT...INSERTED VCTS FROM LATE AFTERNOON INTO TONIGHT. THUNDERSTORM ACTIVITY SHOULD DIMINISH BY LATE TONIGHT...BUT MODELS ARE NOT AGREEING ON CLOUD COVER IN THE THU 09-12Z TIME FRAME. CURRENT THINKING IS THAT CLOUDS WILL LINGER BEHIND THE FRONT AROUND KIND/KHUF/KBMG...PREVENTING FOG DEVELOPMENT. HOWEVER...KLAF HAS THE BEST CHANCE OF CLEARING OUT. SO...FOG MAY HAVE TO BE INSERTED THERE WITH NEXT TAF ISSUANCE. CONFIDENCE IS TOO LOW AT THIS TIME TO INCLUDE IN THIS TAF PACKAGE. WINDS WILL BE SOUTHWESTERLY AT 5 TO 10 KTS INTO TONIGHT...AND THEN SHIFT TO THE NORTH BEHIND THE FRONT. SOME GUSTS UP TO 20 KTS CANNOT BE RULED OUT WITH FRONTAL PASSAGE. FORECAST SOUNDINGS AND TIME CROSS SECTIONS ARE INDICATING THAT THE DRY POST FRONTAL AIR WILL FILTER INTO THE AREA RATHER QUICKLY...WITH CLOUDS SCATTERING OUT BY MID MORNING TOMORROW. && .IND WATCHES/WARNINGS/ADVISORIES...
