Several tall elevated thunderstorms developed along a theta-e gradient on the morning of June 11. One such storm developed over southern Whitley County and supported the development of a deeper cold pool. As the low level jet impinged on the southwestern flank of the outflow bubble, prolonged cell training occurred as a cold pool feedback process resulted. Radar estimated and Flash Flood Monitoring and Predication (FFMP) totals confirmed heavy rainfall in a short duration and prompted the issuance of a Flash Flood Warning (FFW). Flood water to 2 feet deep covered many roads including some main roads. Basements were flooded, including the High School. Rain gauge measurements of up to 5.40 inches in an hour were reported.

.AVIATION/UPDATE...
VEERED/INCREASED FLOW ALOFT IN THE H925 TO H85 LAYER WILL
CONTINUE TO SUPPORT SCT SHOWERS AND THUNDERSTORMS ALONG A NE
MOVING NW-SE ORIENTED LINE. VERY HEAVY RAINFALL IS POSSIBLE IN THE
HEAVIER CELLS WITH VIS REDUCTIONS DOWN TO 1SM. CONVECTION IS
EXPECTED TO CONTINUE TO LIFT NE THROUGH THE MORNING. LATER IN THE
PERIOD...ATTENTION TURNS TOWARD THE DECAYING MCS OVER IA. THIS
SYSTEM WILL LIKELY FORCE NEW CONVECTION IN THE PRESENCE OF DAYTIME
DESTABILIZATION...SUPPORTING INCREASED CHANCES FOR SHOWERS AND
THUNDERSTORMS THIS AFTERNOON...ESPECIALLY ACROSS THE NORTHERN HALF
OF THE FA. HAVE ADDED TEMPOS FOR THIS. OTHER SCT ACTIVITY WILL BE
POSSIBLE OVER THE REST OF THE FA GIVEN AMPLE LL MOISTURE COUPLED
WITH SEVERAL WEAK DISTURBANCES IN SOUTHERLY FLOW. VIS AND CIG
RESTRICTIONS DOWN TO IFR ARE EXPECTED IN THE HEAVIER CELLS. VERY
HEAVY RAINFALL WILL BE POSSIBLE IN A SHORT DURATION...WITH 1-2
INCHES PER HOUR NOT OUT OF THE QUESTION. ISOLATED SEVERE WEATHER
WILL BE POSSIBLE WITH THE HEAVIEST CELLS...SUPPORTING THE POTENTIAL
FOR ISOLATED DAMAGING DOWNBURSTS GIVEN PROGGED SB CAPES AND STEEP
LL LAPSE RATES.

SHORT TERM.../TODAY THROUGH SATURDAY NIGHT/...
WARM AND HUMID CONDITIONS SET TO RETURN AS RIDGING WILL REASSERT
ITSELF OVER THE REGION IN RESPONSE TO STRONG 140 KNOT UPPER JET
DEEPENING WESTERN TROUGH THROUGH THE GREAT BASIN. WARM FRONTAL
BOUNDARY LYING JUST TO OUR SOUTHWEST WILL SURGE NORTH ACROSS THE
AREA BEGINNING EARLY THIS MORNING. DEWPOINTS SOUTH OF THE FRONT
CURRENTLY ARE VERY JUICY...INTO THE 70S....AND BY EVENING
DEWPOINTS WILL BE PUSHING 70 ACROSS MOST OF THE CWA. EARLY THIS
MORNING MODELS ARE DEVELOPING SOME ACTIVITY ALONG STRONG THETA-E
SURGE WITH WEAKLY CONVERGENT BL WINDS...AND SCT TSRA HAVE BEEN
POPPING UP AHEAD OF SCHEDULE ALREADY THIS MORNING TO OUR SOUTH AND
WEST ALONG THE LEADING INFLUENCE OF THE BOUNDARY. WILL ADJUST
POPS ACCORDINGLY WITH AN EARLIER INCREASE IN THE WEST. BY THIS
AFTERNOON...AIRMASS BECOMES INCREASINGLY UNSTABLE AS BL MOISTURE
INCREASES DRAMATICALLY WITH MLCAPE AOA 1000J/KG. LACKLUSTER
0-6KM SHEAR FORECAST TO BE IN PLACE COMBINED WITH FZ LEVELS NEAR
15KFT WILL LIMIT CHANCES OF SEVERE CELLS/HAIL THREAT...IN LINE
WITH NEW DAY 1 OUTLOOK WHICH KEEPS SLIGHT RISK TO OUR NORTH WHERE
DEEP LAYER SHEAR IS MORE SUPPORTIVE. KEPT MID RANGE CHC POPS
ACROSS THE AREA FOR CONVECTIVE NATURE OF AFTERNOON PRECIP.
LATE FRIDAY NIGHT/EARLY SATURDAY...COMPACT SHRTWV IN WEAK SOUTHERN
STREAM FLOW AROUND SE CONUS RIDGING WILL PROGRESS JUST SOUTH OF THE
CWA. WITH AN ALREADY MOIST UNSTABLE AIRMASS IN PLACE AND ENHANCED 50
KNOT H85 LLEVEL JET INTO SOUTHERN INDIANA...THIS FEATURE WILL SURELY
SERVE TO FIRE MORE WIDESPREAD TSRA WITH THE MAIN QUESTION BEING
NORTHWARD EXTENT. 00Z LOCAL WRF/21Z SREF ARE IS FURTHEST NORTH
WITH SFC/H5 LOW TRACK THROUGH CENTRAL INDIANA WHILE 00Z
NAM/GFS/ECMWF REMAIN JUST NORTH OF THE OHIO RIVER. WITH UNSTABLE
AIRMASS OVERHEAD WILL CONTINUE CHC POPS EVERYWHERE...AND HIGHER
VALUES ALONG THE SOUTHERN THIRD OF THE FA.
TEMPS ON THE RISE WITH QUITE A DISPARITY IN GUIDANCE FOR SAT AND
WILL STAY CLOSER TO THE WARMER MAV IN THE NORTH FURTHER FROM
INFLUENCE OF POTNL CONVECTIVE COMPLEX WHILE MODERATING NUMBERS INTO
THE MID 80S SOUTH WHERE CLOUDS/PRECIP POTENTIAL SHOULD HELP TAKE
THE EDGE OFF AFTERNOON READINGS...THOUGH SOME FASTER MODEL GUIDANCE
WOULD INDICATE SOME AFTERNOON SUN NOT OUT OF THE QUESTION AS WAVE
SLIDES EAST. A COUPLE OF MUGGY NIGHTS IN STORE AS MOISTURE KEEPS
MINS NEAR 70.
LONG TERM.../SUNDAY THROUGH THURSDAY/...
WHILE THE MODELS ALL VARY IN SOLUTION...THE TREND IS FOR THE RIDGING
OVER THE SOUTHEASTERN U.S. TO WEAKEN AS A SERIES OF SHORT WAVES AND
SLOW MOVING SYSTEMS OVER THE CENTRAL US CONTINUE TO EJECT EAST. THE
MAIN SURFACE LOW WILL GRADUALLY SHIFT EAST AND DRAG AN ASSOCIATED
COLD FRONT THROUGH THE GREAT LAKES DURING THE EARLY PART OF THE
EXTENDED PERIOD.
WHILE TIMING DIFFERENCES MAKE THIS A CHALLENGING FORECAST...THE
FOCUS OF CONVECTION WILL BE DRIVEN BY AN ABUNDANCE OF INSTABILITY
OVER THE REGION. SHEAR WILL BE FOCUSED BEFORE AND ALONG THE ACTUAL
FRONTAL PASSAGE...SO EXPECT THE POTENTIAL FOR SOME HEAVY RAINFALL
EARLY SUNDAY WITH MORE ORGANIZED CONVECTION FORMING DURING THE
LATTER PART OF SUNDAY INTO SUNDAY NIGHT AS THE FRONT APPROACHES.
THIS PATTERN WILL PERSIST THROUGH THE DAY MONDAY AS THE FRONT SLOWLY
SHIFTS SOUTH AND EAST. WITH THE FRONTAL BOUNDARY BECOMING NEARLY
STATIONARY DURING MONDAY...THERE WILL BE A CONTINUED THREAT OF
CONVECTION MONDAY THROUGH EARLY WEDNESDAY. THE CURRENT FORECAST
GRIDS HAVE CHANCE OF THUNDERSTORMS FROM SUNDAY THROUGH TUESDAY
NIGHT...BUT THE BEST CHANCES FOR CONVECTION WILL BE DIURNALLY
DRIVEN. DUE TO THE UNCERTAINTY AND LOW CONFIDENCE OF TIMING THE
ACTUAL ONSET OF CONVECTION...HAVE OPTED TO BROAD BRUSH CHANCE POPS
DURING THIS PERIOD.
WEDNESDAY AND THURSDAY APPEAR TO BE SOMEWHAT LESS FAVORABLE FOR
CONVECTION AS MODELS ARE TRENDING TOWARD ANOTHER RIDGE BUILDING BACK
INTO THE REGION. THIS WILL SET THE STAGE FOR GRADUAL WARMING AND AN
INCREASE OF MOISTURE BACK INTO THE REGION TOWARD THE LATTER PART OF
THE FORECAST PERIOD.
