AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 630 PM EDT SUN JUN 27 2010 .UPDATE... THE AVIATION SECTION HAS BEEN UPDATED BELOW. && .SYNOPSIS... A COLD FRONT WILL APPROACH INDIANA THIS AFTERNOON...AND CROSS THE STATE TONIGHT THROUGH EARLY MONDAY. A LARGE RIDGE OF HIGH PRESSURE WILL BUILD BACK OVER THE REGION TUESDAY THROUGH THE EARLY PART NEXT WEEKEND. && .NEAR TERM /LATE AFTERNOON THROUGH TONIGHT/... CONFIDENCE IS RATHER LOW ON HOW CONVECTION WILL EVENTUALLY EVOLVE. MCV LOCATED OVER SOUTHERN LAKE MICHIGAN...BUT SO FAR CONVECTION WITH THIS FEATURE IS SLOW TO DEVELOP. MAY HAVE TO WAIT UNTIL CLOSER TO SUNSET AND LATER WHEN THE LOW LEVEL JET BEGINS TO INCREASE AND INTERACT WITH APPROACHING FRONT. ORIENTATION OF 850MB THERMAL RIDGE...DECENT LOW LEVEL JET...AND HIGH PRECIPITABLE WATERS STILL POINT TO HIGH COVERAGE OF CONVECTION AND HEAVY RAIN THREAT...ESPECIALLY OVER THE CENTRAL AND SOUTHERN PARTS OF THE FORECAST AREA. WILL KEEP HIGH POPS GOING TONIGHT. APPEARS AFTER 280600Z...WARM ADVECTION BEGINS TO TAPER OFF...SO PRECIPITATION MAY TEND TO DIMINISH BY THE EARLY MORNING HOURS ON MONDAY. WILL KEEP FLASH FLOOD WATCH AS IS. DECIDED TO KEEP HEAT ADVISORY GOING AS WELL...WITH SEVERAL STATIONS NEAR OR AT ADVISORY CRITERIA. LOW LEVEL THICKNESSES SUGGEST NUDGING DOWN THE GFS MOS LOWS TONIGHT A COUPLE OF DEGREES. && .SHORT TERM /MONDAY THROUGH WEDNESDAY/... UPPER TROUGHING EXPECTED TO DEVELOP OVER THE EASTERN PARTS OF THE COUNTRY BY MID WEEK...WHICH SHOULD AID IN BRINGING DRIER AND MORE STABLE AIR TO THE AREA. WILL KEEP SOME CHANCE POPS OVER THE SOUTHERN ZONES UNTIL ABOUT MIDDAY MONDAY TO COVER ANY LINGERING ACTIVITY...OTHERWISE FORECAST WILL BE DRY INTO WEDNESDAY WITH SURFACE HIGH PRESSURE BUILDS IN. LOW LEVEL THICKNESSES SUGGEST THE GFS MOS HIGHS FOR WEDNESDAY MAY BE A LITTLE ON THE WARM SIDE...OTHERWISE GUIDANCE LOOKS OK. && .LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/... GFS/EURO AND OTHER ENSEMBLE DATA CONTINUE TO SHOW A LARGE STRENGTHENING UPPER RIDGE OVER THE CENTRAL UNITED STATE AND THEN SLOWLY SHOW THIS FEATURE SHIFTING EASTWARD AS THE REST OF THE WEEK PROGRESSES...TO A POSITION EAST OF THE GREAT LAKES BY LATE WEEKEND. NE/E FLOW DURING THE MAJORITY OF THE PERIOD WILL BRING SLIGHTLY BELOW NORMAL READINGS TO CENTRAL INDIANA. TEMPS WILL BEGIN TO WARM INCREMENTALLY TOWARD THE END OF THE WEEK AS RETURN FLOW SETS IN BEHIND THE RIDGE. EXTENDED PERIOD WILL BASICALLY REMAIN DRY UNTIL POSSIBLY LATE IN THE WEEKEND INTO MONDAY WHEN THE REMNANTS OF ALEX COULD MAKE IT/S WAY UP THE FROM THE GULF. THE GFS IS BY FAR THE MOST AGGRESSIVE WITH THIS SOLUTION....WHILE THE EURO SHOWS ALEX BEING SUPPRESSED IN THE GULF BY THE RIDGE. THE GEM SEEMS TO LEAN MORE TOWARD THE GFS SOLUTION...BUT TAKES THE TRACK FURTHER WESTWARD. && .AVIATION /280000Z TAF ISSUANCE/... LINES OF TSRA CONTINUE TO DEVELOP ALONG AREAS OF CONVERGENCE IN AN UNSTABLE ATMOSPHERE. WILL TRY AND TIME BEST WINDOW FOR TSRA WITH TEMPO GROUPS...BUT WILL LEAVE AT LEAST CB IN PAST 06Z TO ACCOUNT FOR THE POSSIBILITY OF DIFFERENT LINES MOVING THROUGH. OUTSIDE OF TSRA...EXPECT VFR CONDITIONS WITH WIND GUSTS DIMINISHING EARLY. AREAS THAT RECEIVE RAIN THIS EVENING WILL LIKELY SEE SOME MVFR FOG FOR A PERIOD NEAR 12Z. EXPECT VFR CEILINGS THOUGH. DRIER AIR DOES NOT ARRIVE UNTIL AFTER 18Z MONDAY...AFTER WHICH CLOUD COVER SHOULD DECREASE. WINDS MAY SHIFT DIRECTION FROM SW TO NW AND BACK TO SW AGAIN WITH PASSAGE OF TSRA SYSTEMS...BUT MAIN WIND SHIFT TO NW BEHIND THE COLD FRONT WILL NOT OCCUR UNTIL MONDAY AFTERNOON. && .IND WATCHES/WARNINGS/ADVISORIES...
