AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
755 PM EDT WED JUN 26 2013
.SYNOPSIS...
WARM AND HUMID CONDITIONS WILL REMAIN ACROSS THE REGION TONIGHT. A
COLD FRONT WILL WORK ACROSS THE AREA LATE TONIGHT INTO THURSDAY.
THIS WILL BRING A CONTINUED CHANCE FOR SHOWERS AND THUNDERSTORMS.
SOMEWHAT COOLER CONDITIONS ARE EXPECTED FOR FRIDAY AND THE
WEEKEND...BUT OCCASIONAL CHANCES OF SHOWERS AND THUNDERSTORMS WILL
REMAIN POSSIBLE.
&&
.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
CONVECTIVE COMPLEX IN SRN INDIANA IS CONTINUING TO DEVELOP TO THE
E AS IT ENCOUNTERS A DESTABILIZING ATMOSPHERE. PRIMARILY SEVERE
THREAT SHOULD BE IN FORM OF DAMAGING WIND AS THE COMPLEX IS TAKING
ON A BOWING STRUCTURE AND IT MOVES E.
WENT WITH CATEGORICAL POPS FOR THE REGION TONIGHT AS A H5 S/W
DIGGING ACROSS THE GREAT LAKES AND INTO THE OHIO VALLEY SHOULD AID
IN THE TSTM DEVELOPMENT. EXTENDED THE FLASH FLOOD WATCH ACROSS THE
ENTIRE REGION AS SEVERAL COUNTIES IN THE N HAVE FFG AROUND 1 INCH
PER HOUR. WITH THE HIGH PW AND A FOCUSING LOW LEVEL JET...THE
POTENTIAL FOR HEAVY RAIN IS HIGH.
WENT WITH THE LOWS IN THE UPPER 60S ACROSS THE REGION.
&&
.SHORT TERM /6 AM THURSDAY MORNING THROUGH THURSDAY NIGHT/...
THE S/W SHOULD BE EAST OF THE FA BY 15Z...BUT LARGER SCALE
H5 LOW WILL BE BUILDING IN THROUGH ONTARIO. DESPITE THE PASSAGE OF
A SFC LOW AND CDFNT...THE ATMOSPHERE WILL NOT HAVE STABILIZED TOO
MUCH. SHRA AND TSRA ARE POSSIBLE AGAIN THURSDAY...ESPECIALLY IN
THE EASTERN CWA. OVERALL FORCING WILL BE WEAK THU NGT...BUT WITH A
SLIGHTLY UNSTABLE ATMOSPHERE...THERE IS A LINGERING CHANCE OF
CONVECTION.
HIGHS ON THURSDAY WILL BE COOLER...RANGING FROM THE LOWER 80S INT
HE N TO THE MID 80S IN THE S. LOWS THU NGT WILL STILL BE INT HE
MID TO UPPER 60S
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
VERY UNSETTLED PATTERN TO DEVELOP AS AMPLIFIED LONGWAVE FLOW SETS
UP AND PERSISTS THROUGH THIS PERIOD. COULDN/T REALLY FIND A DECENT
PERIOD TO INDICATE PROLONGED DRY CONDITIONS...WITH LONGWAVE TROUGH
DEVELOPING/DEEPENING SW TO NE ALONG AND WEST OF THE APPALACHIAN
CHAIN. TWO MASSIVE RIDGES...ONE OVER THE WEST CONUS AND ONE OVER
THE ATLANTIC...RETROGRADE AND AMPLIFY THROUGH THE PERIOD WITH THE
WEAKNESS/TROUGH BETWEEN THE TWO ALSO GAINING AMPLITUDE. NEGATIVE
HEIGHT ANOMALIES ARE SIGNIFICANT AS THE TROUGH DEEPENS ESPECIALLY
TO THE SOUTH OF THE OHIO VALLEY. SUCH A DEEP TROUGH IN THE HEART
OF SUMMER MEANS THAT DAILY FLAREUPS OF CONVECTION ARE LIKELY...AND
WILL BE ESPECIALLY LIKELY TIED TO WEAK WAVES MOVING THROUGH THE
NWLY FLOW UNDERNEATH THE TROUGH EARLY IN THE PERIOD...AND IN THE
SLY FLOW AHEAD OF THE TROUGH LATE IN THE PERIOD AS THE TROUGH AXIS
DRIFTS TO THE WEST. LACK OF SCOURING OF THE LOW LEVEL MOISTURE
FIELD MEANS THERE WILL BE PLENTY OF MOISTURE AND MARGINAL INSTBY
FOR DAILY ROUNDS OF SCT STORMS TIED TO THE DIURNAL HEATING CYCLE.
WAVES TO KEY ON /AT LEAST IN THE SHORT TERM/ ARRIVE BOTH FRIDAY
AND SATURDAY SO THESE DAYS HAVE RELATIVELY HIGHER RAIN
CHANCES...BUT THERE WILL LIKELY BE MANY MORE OF THESE WAVES INTO
EARLY NEXT WEEK. TEMPERATURES...WHILE THEY WILL BE A BIT BELOW
NORMAL...WON/T BE TOO COOL GIVEN THE CORE OF THE 850MB TEMP/500MB
HEIGHT ANOMALIES QUICKLY DIG/RETROGRADE SOUTH AND WEST OF THE
AREA. CERTAINLY NO 90S THE FORECAST...BUT A LONGER OF PERIOD OF
UPPER 70S TO MID 80S AND RATHER DAMP/MUGGY CONDITIONS IS IN THE
OFFING.
&&
.AVIATION /00Z THURSDAY THROUGH MONDAY/...
SHOWERS AND SOME THUNDERSTORMS WILL BE POSSIBLE ACROSS THE AREA
THIS EVENING BEFORE GRADUALLY DECREASING IN COVERAGE DURING THE
OVERNIGHT HOURS. SOME LOWER CIGS WILL BE POSSIBLE AROUND THE
KCVG...KLUK...KCMH...AND KLCK LATE IN THE OVERNIGHT HOURS AND INTO
THE EARLY DAYTIME HOURS ON THURSDAY. AT KDAY AND KILN LOWER CIGS
ARE POSSIBLE OVERNIGHT HOWEVER THERE IS MORE UNCERTAINTY AND
