Hail and Damaging Winds in Ohio, June 3, 2014

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
212 PM EDT TUE JUN 3 2014

.SYNOPSIS...
A WEAK SURFACE BOUNDARY WILL PASS SOUTH OF OHIO AND LAY OUT OVER
KENTUCKY THIS EVENING. THIS BOUNDARY WILL BE A FOCUS FOR SHOWERS
AND THUNDERSTORMS INTO TONIGHT...BUT THEN SHIFT NORTHWARD AS A
WARM FRONT EARLY ON WEDNESDAY. A STRONG SURFACE LOW WILL THEN
TRACK EAST ALONG THE WARM FRONT LATER WEDNESDAY...WITH STRONG
THUNDERSTORMS POSSIBLE AS IT PASSES.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A FAIR AMOUNT OF LOW CLOUDS REMAIN IN PLACE ACROSS THE AREA THIS
MORNING. EXPECT THESE CLOUDS TO SLOWLY LIFT AND BEGIN TO THIN OUT
THROUGH LATE MORNING/EARLY AFTERNOON AS WE CONTINUE TO MIX. THIS
WILL ALLOW US TO BEGIN TO FURTHER DESTABILIZE AS WE PROGRESS
THROUGH THE AFTERNOON HOURS...WITH ML CAPES PUSHING INTO THE
1000-2000 J/KG RANGE. A COLD FRONT CURRENTLY SITUATED JUST OFF TO
OUR NORTHWEST WILL PUSH SOUTHEAST INTO OUR AREA THROUGH THE
AFTERNOON HOURS. THE COMBINATION OF SOME WEAK LOW LEVEL CONVERGENCE
ALONG/AHEAD OF THE FRONT AND INCREASING INSTABILITIES...SHOULD LEAD
TO SCATTERED THUNDERSTORM DEVELOPMENT THIS AFTERNOON. THE BEST
COVERAGE SHOULD BE ACROSS OUR SOUTHEAST WHERE INSTABILITY/LOW LEVEL
CONVERGENCE SHOULD BE THE BEST. EXPECT HIGHS TODAY IN THE LOW TO
MID 80S.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
BOUNDARY IN KY WILL LIFT NORTHWARD THROUGH THE AREA EARLY
WEDNESDAY AFTER CLEARING SKIES TONIGHT LETS MOST OF THE REGION
DROP TO THE UPPER 50S OT LOWER 60S. EXTENDED PERIOD OF CLOUD COVER
IN KY AND FAR SE IN WITH SUBSEQUENT DEVELOPMENT OF THE WARM FRONT
WILL HOLD LOWS IN THESE AREAS TO THE UPPER 60S.

AS THE FRONT LIFTS NORTHWARD...IT IS PROGGED TO STALL OUT SOUTH OF
THE I-70 CORRIDOR. A MID LEVEL SHORTWAVE IN FAIRLY QUICK ZONAL
FLOW AT H5 WILL PRECEDE THE SURFACE LOW AND INITIATE CONVECTION
ALONG A LEADING LINE. SPC IS NOTING THE ABUNDANT MOISTURE IN PLACE
SOUTH OF THE WARM FRONT WITH A MCS MOVING EAST ALONG THE BOUNDARY.
ENOUGH WARM AND UNSTABLE AIR MAY OCCUR WITH DAYTIME HEATING SOUTH
OF THE FRONT TO SPAWN MORE THUNDERSTORM DEVELOPMENT ON THE FRINGES
OF THE EXPECTED MCS...SIMILAR TO POPUP STORMS ON AN OUTFLOW
BOUNDARY ONLY IN A SLIGHTLY LARGER SCALE.

EVEN WITH THE NAM LAGGING SIGNIFICANTLY AT H48 THAN THE GLOBAL
MODELS...HAVE ENOUGH CONFIDENCE IN THEM TO INCREASE POPS TO
CATEGORICAL FOR A PERIOD WEDNESDAY AFTERNOON. ALL INDICATIONS OF
AN MCS WORKING THROUGH THE CWA ARE THERE WITH A FOCUS ON THE I-70
CORRIDOR.

WITH THE PRESENCE OF THE SURFACE LOW AND ITS ASSOCIATED
SHEAR...STORMS THAT DO DEVELOP ON WEDNESDAY HAVE A HIGHER
POTENTIAL FOR SUPERCELLULAR ACTIVITY AND SEVERE WEATHER.

ONCE STORMS PASS TO THE OHIO RIVER WEDNESDAY EVENING...UNLESS
SLOWER NAM IS CORRECT...NORTH WINDS IN THE WAKE OF THE LOW WILL
PUSH DRIER AND COOLER AIR TO THE REGION SO THAT HIGHS THURSDAY
WILL BE IN THE LOWER 70S AND READINGS ON FRIDAY WILL STILL BE HARD
PRESSED TO REACH 80 IN THE FAR SOUTH. OVERNIGHT LOWS IN THE 50S
WILL ALSO BE QUITE WELCOME.

&&

.LONG TERM /FRIDAY NIGHT THROUGH MONDAY/...
FLOW BACKS WITH NEXT SYSTEM AFFECTING THE OHIO VALLEY LATE IN THE
WEEKEND. NUMERICAL MODEL SOLNS HAVE COME IN CLOSER AGREEMENT
REGARDING TIMING AND PLACEMENT. HAVE ALLOWED CHANCE POPS TO
DEVELOP LATE SATURDAY NIGHT AND CONTINUED THRU SUNDAY...ENDING
LATE SUNDAY NIGHT/EARLY MONDAY.

WARM AND MOIST CONDITIONS WILL KEEP MAX AND MIN TEMPERATURES AROUND
5 DEGREES ABOVE NORMAL WEDNESDAY BUT THEN WILL DROP A LTL BELOW
NORMAL THURSDAY. NEAR NORMAL READINGS ARE EXPECTED FRIDAY BEFORE
RISING A LTL ABOVE NORMAL SATURDAY/SUNDAY.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
AIRMASS HAS DESTABILIZED ACROSS THE AREA THIS AFTERNOON WITH
MLCAPES NOW INTO THE 1000-1500 J/KG RANGE. THIS HAS ALLOWED FOR
SOME ISOLATED SHOWER/THUNDERSTORM DEVELOPMENT AHEAD OF AN
APPROACHING COLD FRONT. THIS FRONT WILL CONTINUE TO SAG SOUTHEAST
ACROSS OUR AREA THROUGH LATE AFTERNOON EARLY EVENING. WITH SOME
ADDITIONAL DESTABILIZATION POSSIBLE AND CU FIELD LOOKING MORE AND
MORE ENHANCED ON VISIBLE SATELLITE IMAGERY...EXPECT TO SEE SOME
ADDITIONAL THUNDERSTORM DEVELOPMENT ALONG AND SOUTHEAST OF THE I-71
CORRIDOR THROUGH MID AFTERNOON. AS THE FRONT PUSHES SOUTHEAST AND
WE LOSE SOME DIURNAL HEATING...EXPECT THUNDERSTORM THREAT TO
DIMINISH AT THE TAF SITES BY EARLY EVENING.

THE BOUNDARY WILL LIFT BACK NORTH AS A WARM FRONT LATE TONIGHT
INTO WEDNESDAY. MODELS CONTINUE TO FLUCTUATE ON THEIR TIMING AND
PLACEMENT OF THIS FRONT AS WELL AS THE EASTWARD TIMING/TRAJECTORY
OF AN MCS APPROACHING FROM THE WEST OVERNIGHT. THE OVERALL TREND
DOES APPEAR TO BE THAT THIS MCS WILL BEGIN TO WEAKEN/CONGEAL INTO
MORE OF A RAIN WITH EMBEDDED THUNDERSTORM TYPE COMPLEX LATE
TONIGHT/EARLY WEDNESDAY AS IT APPROACHES OUR AREA. THIS COMPLEX
WILL HAVE AN AFFECT ON HOW FAR NORTH THE FRONT MAKES IT ON
WEDNESDAY AND ALSO HOW QUICKLY WE ARE ABLE TO DESTABILIZE THROUGH
THE AFTERNOON. ASSUMING WE ARE ABLE TO DESTABILIZE
SUFFICIENTLY...SHEAR PROFILES ARE FAVORABLE FOR ORGANIZED STORM
DEVELOPMENT THROUGH WEDNESDAY AFTERNOON. WILL COVER THIS UNCERTAINTY
IN THE EXTENDED KCVG TAF PERIOD WITH A -SHRA/VCTS FROM MID
AFTERNOON ONWARD.

OUTLOOK...THUNDERSTORMS ARE LIKELY THROUGH EARLY THURSDAY MORNING.
