Hail and Damaging Winds in Ohio, July 5, 2012

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
1214 PM EDT THU JUL 5 2012

.SYNOPSIS...
UPPER LEVEL HIGH PRESSURE WILL EXPAND ACROSS THE REGION THROUGH
THE REST OF THE WEEK KEEPING A HOT AIR MASS IN PLACE. THE HEAT
WAVE WILL BREAK EARLY NEXT WEEK AFTER A COLD FRONT MOVES THROUGH
SUNDAY...ALLOWING COOLER AIR TO MOVE IN.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
OUTFLOW BOUNDARY FROM EARLIER CONVECTION IS CURRENTLY STRETCHING
FROM EAST CENTRAL INDIANA INTO FAR SOUTH CENTRAL OHIO. THE
SOUTHWEST PROGRESSION OF IT HAS SLOWED DOWN SO IT WILL LIKELY
STALL OUT ACROSS OUR FAR SOUTH THROUGH THIS AFTERNOON. EXPECT
THIS TO BE THE MAIN FOCUS FOR ANY AFTERNOON CONVECTION SO HAVE
ADJUSTED POPS ACCORDINGLY. TEMPERATURES BEHIND THE BOUNDARY HAVE
DROPPED OFF A FEW DEGREES AND AMOUNT OF RECOVERY WILL STILL DEPEND
ON HOW MUCH THE DEBRIS CLOUDS DISSIPATE. THE CLOUDS ARE TRYING TO
THIN SO WILL STILL BANK ON ENOUGH CLEARING TO GET CENTRAL OHIO
BACK UP INTO THE MID 90S.
&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
EVEN THOUGH THE CAP WILL CONTINUE TO BUILD OVER THE
AREA...CONVECTION THAT INITIATES IN AND AROUND THE OHIO VALLEY
FOR THE REST OF THE WEEK WILL PRODUCE OUTFLOW BOUNDARIES THAT HAVE
A HIGH POTENTIAL FOR SPARKING ADDITIONAL STORMS. ANY STORMS THAT
DEVELOP SHOULD BE PREDISPOSED TO GROW LARGE DUE TO THE UNSTABLE
NATURE OF THE MID LEVELS OF THE ATMOSPHERE. DEEP CONVECTION WILL
CONTAIN HAIL...OCCASIONALLY LARGE ENOUGH TO WARRANT SEVERE
WARNINGS.

HIGH TEMPERATURES WILL CONTINUE TO REACH THE UPPER 90S AND INTO
THE TRIPLE DIGITS FOR THE REMAINDER OF THE FORECAST PERIOD. LOW
TEMPERATURES WILL RISE A LITTLE BIT EACH NIGHT TO TOP OUT IN THE
MIDDLE 70S. BY LATE SATURDAY NIGHT...THE FRONT IS PROGGED TO BE
IN THE SOUTHERN FORECAST AREA.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
THE GFS IS A LOT QUICKER WITH THE FRONTAL BOUNDARY AND THE
PRECIPITATION AND BEGINS TO BRING PRECIPITATION INTO THE AREA
SATURDAY NIGHT. THE ECMWF IS SLOWER WITH THE PRECIPITATION AND
BRINGS THE BEST CHANCE OF PRECIPITATION INTO THE AREA SUNDAY
NIGHT. WENT CLOSER TO THE ECMWF SOLUTION AND HAVE THE GREATEST
PRECIPITATION CHANCES IN THE FORECAST DURING THE OVERNIGHT HOURS
SUNDAY NIGHT INTO MONDAY MORNING. PRECIPITATION WILL THEN LINGER
ACROSS SOUTHERN PORTIONS OF THE FA MAINLY IN NORTHERN KENTUCKY
MONDAY NIGHT INTO TUESDAY BEFORE COMPLETELY EXITING THE AREA.
AFTER SATURDAY THERE WILL BE A GENERAL DECREASE IN TEMPERATURES
FOR THE REST OF THE LONG TERM TIME FRAME. TEMPERATURES BY MONDAY
AND TUESDAY WILL BE IN THE 80S ACROSS THE ENTIRE FA.

&&

.AVIATION /16Z THURSDAY THROUGH MONDAY/...
ATMOSPHERE REMAINS UNSTABLE AND CONVECTION CONTINUES TO POP HERE
AND THERE. ONE OF THESE AREAS IS ACROSS NORTH CENTRAL OHIO NR
MANSFIELD. THIS CONVECTION HAS BEEN DRIFTING S...SO IT COULD END UP
AFFECTING CMH/LCK LATER. RIGHT NOW HAVE COVERED THAT POSSIBILITY
WITH A VCTS AFT 14Z.

FOR THE REST OF THE TAF PERIOD...NE FLOW ON THE ERN EDGE OF THE H5
RIDGE...WILL STEER IMPULSES AND CONVECTION TOWARDS THE REGION.
MODELS HANDLE IMPULSES IN THE FLOW DIFFERENTLY...SO SOME MODELS
POP AFTN CONVECTION WHILE OTHER HOLD OFF AND TRY AND DEVELOP
ANOTHER COMPLEX AND DROP IT SE INTO THE REGION.

FEEL THAT THERE WILL BE CONVECTION IN THE TAF REGION DURING THE
TAF PERIOD...BUT WITH NO GOOD SIGNAL...THE CONFIDENCE REMAINS TOO
LOW FOR ANY MENTION IN THE TAFS AT THE MOMENT OTHER THAN THE VCTS
AT CMH/LCK.

CI BLOW OFF FROM COMPLEX IN SRN MI WILL SPREAD OVER SOME OF THE
TAFS THIS MORNING....BUT EXPECT VFR CIGS. MORNING FOG AT LUK
SHOULD DISSIPATE QUICKLY. GUIDANCE IS INDICATING THE POSSIBILITY
OF MORE FOG TOMORROW AND THAT IT MIGHT AFFECT ALL TAF LOCATIONS.
RIGHT NOW ONLY INCLUDED IT AT THE TWO FOGGY LOCATION OF LUK AND ILN.

OUTLOOK...THUNDERSTORMS POSSIBLE SUNDAY.
