NWS Indianapolis, IN wrote its last area forecast discussion before the first event at Jun 4, 8:54 PM EST, 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE INDIANAPOLIS IN 954 PM EDT FRI JUN 4 2010 .UPDATE... AVIATION SECTION AND NEAR TERM HAS BEEN UPDATED. && .SYNOPSIS... FORCAST AREA WILL REMAIN IN THE WARM SECTOR TONIGHT UNTIL TOMORROW NIGHT WHEN A WAVE MOVES ALONG THE FRONT NEAR OUR NORTHERN FORECAST AREA AND DRAGS A COLD FRONT SOUTHEAST ACROSS CENTRAL OVERNIGHT SATURDAY NIGHT. && .NEAR TERM /TONIGHT/... RADAR WAS SHOWING A COUPLE OF STRONG TO SEVERE THUNDERSTORMS ONE ACROSS CARROLL COUNTY AND ONE JUST NORTH OF HARTFORD CITY LATE THIS EVENING AND ADDITIONAL STORMS ACROSS NORTHERN MISSOURI AND WEST CENTRAL ILLINOIS NEAR NOSE OF LOW LEVEL JET. THESE STORMS HAVE GENERALLY BEEN WEAKENING DUE TO SUBSIDENCE ALOFT IN THE WAKE OF A SHORT WAVE MOVING INTO OHIO BUT COULD FLARE AGAIN OVERNIGHT AS THEY MOVE INTO CENTRAL INDIANA. RAISED POPS A BIT ACROSS OUR SOUTHERN FORECAST AREA BASED ON UPSTREAM RADAR TRENDS FAVORING NORTHERN MISSOURI AND WEST CENTRAL ILLINOIS STORMS FOLLOWING 850-300 MILLIBAR THICKNESS LINES AND CONTINUING TO MOVE SOUTHEAT BUT STILL KEEP GOOD CHANCE POPS NORTH AND ESPECIALLY NORTHEAST BASED ON CURRENT ACTIVITY ACROSS CARROLL COUNTY. SPC HAS PULLED THE SLIGHT RISK FROM ALL BUT OUR NORTHERN COUNTIES TO ACCOUNT FOR ONGOING STORMS...SO WILL ADDRESS THAT IN THE HWO. FINALLY...WITH THE STORMS MOVING A AROUND 25 MPH...SCATTERED NATURE OF THE THUNDERSTORM ACTIVITY AND EXPECTED IOWA MCS NOT HAPPENING YET...DONT THINK HEAVY RAIN NEEDS TO BE MENTIONED...BUT WILL KEEP BRIEF HEAVY RAIN IN THE HWO. WILL KEEP TEMPERATURES UP TONIGHT CONSIDERING CURRENT DEW POINTS STILL IN THE UPPER 60S AT MOST LOCALES AND ANVIL DEBRIS SPREADING ACROSS FROM THE MISSOURI AND ILLINOIS ACTIVITY. && .SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/... THE FIRST HALF OF THE EXTENDED WILL REMAIN ACTIVE AS FRONTAL BOUNDARY CONTINUES TO BE THE FOCUS FOR STRONG TO SEVERE CONVECTION. WHILE SUBTLE TIMING AND LOCATION DIFFERENCES EXIST BETWEEN SPECIFIC MODELS...HAVE ONCE AGAIN LEANED TOWARDS AN ENSEMBLE APPROACH HEADED BY THE SREF. ANTICIPATE THUNDERSTORMS WILL BE ONGOING ACROSS AT LEAST THE NORTHERN HALF OF THE FORECAST AREA SATURDAY MORNING AS MCS THAT DEVELOPS OVERNIGHT ARRIVES AT NOSE OF LOW LEVEL JET. THIS ACTIVITY LIKELY TO BE IN PLACE FOR THE FIRST HALF OF THE DAY AS FRONT REMAINS NEARLY STATIONARY OVER NORTHERN COUNTIES. TO THE SOUTH...INCREASING AMOUNTS OF SUNSHINE AS THE DAY PROGRESSES AND LARGELY DEPENDENT ON THE EXTENT OF THE CIRRUS SHIELD ASSOCIATED WITH THE CONVECTION. HAVE CONTINUED TO CARRY LIKELY POPS OVER NORTHERN THIRD OF THE FORECAST AREA WITH POPS DROPPING OFF FURTHER SOUTH AWAY FROM THE BOUNDARY. WHILE POTENTIAL FOR STRONG TO SEVERE THUNDERSTORMS IS CERTAINLY LIKELY WITH THE MORNING CONVECTION...GROWING CONCERN FOR WIDESPREAD SEVERE WEATHER EXISTS DURING THE AFTERNOON AND EVENING AS WAVE KICKS OUT OF THE MID MISSISSIPPI VALLEY AND THE FRONT SETTLES NEAR OR JUST NORTH OF THE FORECAST AREA. AS MENTIONED ABOVE...SOUTHERN EXTENT OF THE CIRRUS SHIELD WILL IMPACT HEATING ACROSS THE REGION TO SOME DEGREE THROUGH THE MORNING BUT ONCE THE CORE OF THE MCS REMNANTS PASS TO THE NORTHEAST OF THE REGION BY MID AFTERNOON...MOST IF NOT ALL OF THE FORECAST AREA SHOULD SEE SOME SUNSHINE WITH ATMOSPHERE PROGGED TO BECOME UNSTABLE RAPIDLY DURING THE LATE AFTERNOON. AS LOW LEVEL JET LIFTS INTO THE REGION AND STRENGTHENS DURING THE LATE AFTERNOON AND EVENING...RICH MOISTURE WILL TRANSPORT INTO THE FORECAST AREA WITH CAPES POTENTIALLY EXCEEDING 3000 J/KG IMMEDIATELY AHEAD OF THE LOW BY THE EVENING. INTENSE UPPER JET ACROSS THE LOWER GREAT LAKES WILL PROMOTE EXCELLENT MID/UPPER LEVEL DIFFLUENCE WITH BL SHEAR VALUES INCREASING TO NEAR 50KTS AHEAD OF THE SHARPENING UPPER TROUGH. RESULT LOOKING MORE AND MORE LIKE A POTENTIALLY HIGH INSTABILITY/HIGH SHEAR ENVIRONMENT. IMPRESSIVE 0-3KM SRH VALUES OF 200-300 M2/S2 NOTED BY EARLY EVENING...ESPECIALLY IN VICINITY OF THE BOUNDARY AND SUBSEQUENT LOW TRACK THROUGH NORTHERN FORECAST AREA. BELIEVE ALL MODES OF SEVERE WEATHER WILL BE PRESENT AND SHOULD ALL OF THE PARAMETERS DISCUSSED ABOVE COME TOGETHER...WIND FIELDS WOULD SUGGEST WE COULD BE LOOKING AT SUPERCELLS DEVELOPING OVER NORTHERN COUNTIES WITH CONVECTION COALESCING INTO A INTENSE BOW ECHO OR DERECHO FURTHER SOUTH. FORECAST HODOGRAPHS...PARTICULARLY OVER FAR NORTHERN COUNTIES RATHER IMPRESSIVE AND CERTAINLY SUPPORT THE POTENTIAL FOR TORNADOES CONSIDERING THE EXPECTED TRACK OF THE LOW AND TRIPLE POINT. STILL FEEL DAMAGING WINDS WILL BE THE MAIN THREAT WITH THE CONCERN FOR DEVELOPMENT OF A BOW ECHO/DERECHO AHEAD OF THE FRONT. HOWEVER...TRENDS NOTED ON THE SREF AND OTHER MODELS WITH RESPECT TO SHEAR/HELICITY AND POTENTIAL FOR ROTATING STORMS CANNOT BE IGNORED...ESPECIALLY IN VICINITY OF THE BOUNDARY. WILL BE MENTIONING THESE THREATS ALONG WITH LARGE HAIL IN THE HWO. PWATS WILL SURGE ABOVE 2 INCHES SATURDAY NIGHT AHEAD OF THE FRONT WITH POSSIBILITY FOR TORRENTIAL RAINFALL. COMBINED WITH WHATEVER CAN FALL TONIGHT AND EARLIER ON SATURDAY...MAY BE LOOKING AT SOME LOCALIZED FLOODING PROBLEMS IN AREAS WHERE RAINFALL IS PROLONGED. WILL HOLD OFF ON A FLASH FLOOD WATCH AT THIS POINT IN TIME AS WOULD LIKE TO SE HOW THE CONVECTION SETS UP TONIGHT. HOWEVER...THINK THERE IS A STRONG LIKELIHOOD THAT A WATCH WILL BE NEEDED AT SOME POINT. WILL MENTION HEAVY RAIN THROUGH SATURDAY NIGHT WITH THE STORMS. THE FRONT WILL EXIT THE FORECAST AREA BY SUNDAY MORNING. QUICK DRYING WILL FOLLOW IN WAKE OF THE COLD FRONT AND SHOULD ALLOW SKIES TO QUICKLY CLEAR OUT ACROSS THE REGION. HOWEVER...LOW LEVEL COLD ADVECTION AND THE PRESENCE OF THE UPPER TROUGH OVER THE GREAT LAKES WILL PROMOTE CUMULUS DEVELOPMENT THROUGH THE AFTERNOON DESPITE THE DRIER AIRMASS ADVECTING IN. MOST OF THE SHORT TERM MODEL GUIDANCE INDICATING SOME WEAK INSTABILITY DURING THE AFTERNOON AND EVENING NEAR THE VORT AXIS DROPPING AROUND THE BASE OF THE TROUGH. THIS MAY SERVE TO KICK OFF ISOLATED COLD POOL CONVECTION...ESPECIALLY OVER THE NORTHERN COUNTIES. HAVE HELD OFF ON ANY POPS MENTION YET AS MODEL SOUNDINGS INDICATE SOME MID LEVEL CAPPING...BUT POPS MAY NEED TO BE CONSIDERED IF SIGNALS CONTINUE TO SUGGEST. SKIES WILL CLEAR SUNDAY NIGHT AS HIGH PRESSURE EXPANDS INTO THE REGION. TEMPS...HIGHS SATURDAY CONTINUE TO BE TRICKY AND LARGELY DEPENDENT ON THE HEATING RECEIVED. MOS GUIDANCE IN GENERAL SEEMS TOO COOL CONSIDERING EXPECTATIONS DISCUSSED ABOVE...AND HAVE THEREFORE HELD PRETTY CLOSE TO PREVIOUS FORECAST IN THE MID AND UPPER 80S. THINK LOW 90S POSSIBLE OVER FAR SOUTHERN COUNTIES AND WITH EXPECTED DEWPOINTS IN EXCESS OF 70 DEGREES...HEAT INDICES INTO THE MID AND UPPER 90S. NEAR MOS GUIDANCE THROUGH THE REST OF THE PERIOD. && .LONG TERM /MONDAY THROUGH FRIDAY/... AMPLIFIED UPPER FLOW PATTERN FOR MUCH OF THE PERIOD AS AFOREMENTIONED TROUGH LIFTS OUT OF THE NORTHEAST STATES AND ALLOWS BROAD RIDGE CENTERED OVER THE INTERMOUNTAIN WEST MONDAY TO MIGRATE EAST INTO THE MISSISSIPPI/OHIO VALLEYS BY WEEKS END. LIKE THE SLOWER ECMWF APPROACH THAT HPC FAVORS WITH RIDGE EXPANSION HOLDING OFF UNTIL THE END OF THE SEVEN DAYS. WHILE DEPARTING HIGH PRESSURE AND NORTHERLY FLOW WILL KEEP CONDITIONS DRY AND PLEASANT ON MONDAY...THE LOCATION OF THE TROUGH AND RIDGE FOR MIDWEEK WILL PLACE CENTRAL INDIANA BACK INTO A NORTHWEST FLOW ALOFT WITH A SURFACE BOUNDARY PARKING ITSELF IN THE OHIO VALLEY FOR MIDWEEK. RESULT WILL LIKELY BE A RESUMPTION OF THE UNSETTLED PATTERN HIGHLIGHTED BY MCS CLUSTERS AS WAVES OF LOW PRESSURE RIDE THE BOUNDARY AND THE PERIPHERY OF THE EXPANDING RIDGE. AT THIS POINT...MUCH TOO EARLY TO PIN DOWN SPECIFIC TIMING AND LOCATION IMPACTS...BUT MODEL CONSENSUS SUPPORTING A GENERAL TRACK FROM THE NORTHERN AND CENTRAL PLAINS THROUGH THE OHIO VALLEY. HAVE PLACED CHANCE POPS IN FOR THE FORECAST AREA FROM TUESDAY THROUGH WEDNESDAY NIGHT. POSSIBILITY THIS MAY BLEED INTO THURSDAY AS WELL BUT HAVE LEFT DRY FOR NOW. CONSIDERING POTENTIAL HEAVY AMOUNTS OF RAIN THIS WEEKEND...ADDITIONAL THUNDERSTORMS FOR MIDWEEK MAY EXACERBATE ANY EXTENUATING FLOODING ISSUES. HIGH TEMPERATURES WILL BE KEPT DOWN THROUGH MIDWEEK...RUNNING MAINLY IN THE UPPER 70S/LOWER 80S AND HIGHLY DEPENDENT ON CONVECTIVE COVERAGE AND LOCATION OF THE BOUNDARY. WARMER TEMPERATURES ARRIVE FOR THE END OF THE WEEK WITH THE ARRIVAL OF THE RIDGE...POSSIBLY APPROACHING 90 DEGREES FRIDAY AND SATURDAY. && .AVIATION.../FOR 050000Z TAFS/... A FRONTAL SYSTEM WILL REMAIN JUST NORTH OF OUR FORECAST AREA THROUGH THE DAY ON SATURDAY AND THEN MOVE SOUTH ACROSS CENTRAL INDIANA SATURDAY NIGHT TO NEAR THE OHIO RIVER SUNDAY MORNING. AN AREA OF THUNDERSTORMS ACROSS NORTHERN INDIANA TO NEAR KMLI IN WESTERN ILLINOIS WILL TRACK EAST ACROSS NORTHERN INDIANA THIS EVENING...POSSIBLY AFFECTING KLAF IN A FEW HOURS. QUIET WEATHER WILL BE THE RULE FARTHER SOUTH...ALTHOUGH SOME MODELS HINT AT WIDELY SCATTERED THUNDERSTORMS NEAR THE I70 CORRIDOR LATER TONIGHT. FOR NOW WILL ONLY MENTION A PERIOD OF CB ONLY IN TAFS. MVFR FOG HAZE POSSIBLE LATE TONIGHT...OTHERWISE TAFS SHOULD REMAIN VFR. AN UPPER LEVEL DISTURBANCE WILL MOVE TO NORTHERN INDIANA BY MIDDAY SATURDAY AND NUMEROUS THUNDERSTORMS EXPECTED ACROSS NORTHERN SECTIONS AND SCATTERED THUNDERSTORMS ELSEWHERE MIDDAY SATURDAY AN ON. WINDS WILL BE FROM THE SOUTHWEST 5 TO 8 KNOTS OVERNIGHT AND 10 TO 14 KNOTS DURING THE DAY ON SATURDAY. && .IND WATCHES/WARNINGS/ADVISORIES...
