Area forecast discussion, May 27, 4:40 PM EDT, 2 hours 1 minute before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
440 PM EDT WED MAY 27 2015

.SYNOPSIS...
A WEAK COLD FRONT WILL DROP INTO THE REGION TONIGHT...SETTLING ALONG
THE OHIO RIVER...BUT IT WILL BECOME POORLY DEFINED. MEANWHILE...HIGH
PRESSURE WILL BUILD INTO THE SOUTHERN GREAT LAKES ON THURSDAY. THE
HIGH WILL MOVE OFF TO THE EAST FRIDAY...ALLOWING FOR A RETURN OF
HUMID AIR. THE NEXT SIGNIFICANT WEATHER MAKER WILL OCCUR OVER THE
WEEKEND WHEN A STRONGER COLD FRONT PUSHES INTO THE REGION.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
CONVECTION HAS BEEN SPLITTING THE FA SO FAR THIS AFTERNOON...WITH
NUMEROUS SEVERE THUNDERSTORMS TRACKING FROM NE INDIANA INTO
NW OHIO. FARTHER S...CONVECTION IN CNTL KY IS JUST BRUSHING THE
NRN KY COUNTIES. RADAR LOOP IS SHOWING THAT THE CONVECTION OVER
INDIANA ALONG THE CDFNT IS DEVELOPING BACK TO THE SW. THE HRRR
AND RAP HAVE BEEN HANDLING THE CURRENT CONVECTION THE BEST SO FAR
AND THEY ARE SUGGESTING THAT THE NRN INDIANA CONVECTION WILL TRY
AND WORK INTO NORTHERN PORTIONS OF THE FA LATE THIS AFTERNOON INTO
THIS EVENING. THE BIG QUESTION IS HOW ORGANIZED IT WILL BE WHEN IT
MAKES IT IN. IT LOOKS LIKE THE BEST INSTABILITY AND SHEAR COULD BE
WORKING EAST RIGHT NOW...BUT CANT RULE OUT AN ISOLATED SEVERE. KEPT
POPS ON THE CHANCE CATEGORY FOR NOW ACROSS THE NRN HALF...TAPERING
DOWN TO SLIGHT CHC ALONG THE OHIO RIVER...BUT RISING AGAIN INTO NRN
KY.

AS THE FRONT PUSHES IN LATE THIS EVENING...THE CONVECTION CHANCES
SHOULD END FROM THE NW. THE FRONT TRIES TO WASH OUT AS IT COMES
IN...SO ENDED THE PCPN CHANCES BY 06Z.

AS FOR TEMPERATURES...WITH THE FRONT WORKING IN...THE COOLEST
TEMPERATURES SHOULD BE IN THE NW. SHOULD SEE UPPER 50S FOR LOWS
THERE. DOWN THE SOUTH LOWER TO MID 60S ARE EXPECTED FOR LOWS.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
ON THURSDAY...HIGH PRESSURE WILL BUILD ACROSS THE SOUTHERN GREAT
LAKES. MEANWHILE...THE STALLED AND WEAK FRONT WILL BE LOCATED
AROUND THE OHIO RIVER. THERE IS ENOUGH WEAK FORCING AND
INSTABILITY ACROSS THE SOUTH TO KEEP SLIGHT CHANCE POPS FOR
THURSDAY AFTERNOON. EXPECT THE NORTH TO BE DRY AS THEY WILL BE
CLOSER TO THE HIGH. TEMPERATURES SHOULD WORK INTO THE LOWER TO MID
80S.

THE HIGH WILL SLIP OFF TO THE EAST THURSDAY NIGHT. THIS WILL
BEGIN THE TRANSITION TO SOUTHERN FLOW AND A SLOW GRADUAL INCREASE
OF LOW LEVEL MOISTURE. LOWS WILL FALL INTO THE 60S.

FOR FRIDAY INTO FRIDAY NIGHT A H5 TROUGH WILL SWING THROUGH THE
NRN PLAINS INTO THE GREAT LAKES. THIS WILL COMBINE WITH THE
INCREASING MOISTURE TO PROVIDE A GOOD ENVIRONMENT FOR SCATTERED
THUNDERSTORMS TO DEVELOP. HIGHS FRONTAL SHOULD MAKE THE MID 80S
FOR MOST LOCATIONS.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
PERIOD STARTS WITH APPROACH OF COLD FRONT IN WARM AND HUMID AIR
MASS. EXPECT CONVECTION FOR SATURDAY MAINLY IN THE AFTERNOON AND
EVENING. WILL GO LIKELY POPS FOR NOW BUT COVERAGE COULD WARRANT EVEN
HIGHER POPS. HAVE KEPT LIKELY POPS IN FOR SATURDAY NIGHT WITH A
GRADUAL DRYING TREND THROUGH THE NIGHT. APPEARS AS THOUGH FRONT WILL
BE SLOW TO MAKE PROGRESS AND THUS AT LEAST SCATTERED SHRA AND
THUNDER WILL CONTINUE INTO SUNDAY MAINLY SOUTH PARTS OF CWA. SOME
BETTER DRYING ACROSS THE NORTH. THE FRONT WILL LINGER INTO MONDAY
WITH SCATTERED SHRA AND THUNDER AGAIN MAINLY NEAR THE OHIO RIVER.
SOME DISCREPANCY ABOUT EXTENT OF DRYING FOR TUESDAY AND WEDNESDAY.
WILL OPT FOR TOKEN SMALL POP FOR NOW. TEMPS COOLING DOWN SUNDAY AND
MONDAY BUT WENT AT OR JUST ABOVE GUIDANCE WITH CLOUDS AT NIGHT.
NEAR GUIDANCE FOR TUESDAY AND WEDNESDAY.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
THUNDERSTORMS ARE EXPECTED TO MOVE ACROSS THE REGION AND
POTENTIALLY AFFECT ALL TERMINALS. HOWEVER THERE IS UNCERTAINTY
REGARDING TIMING FOR BEST CHANCE. AT THIS POINT HAVE LEANED
TOWARDS EARLIER TIMING THINKING THAT STORMS WILL DEVELOP IN
INDIANA SHORTLY AND THEN SWEEP ACROSS THE AREA. ADDITIONAL
DEVELOPMENT IS POSSIBLE TOWARDS 00Z AHEAD OF AN APPROACHING COLD
FRONT. THREAT FOR STORMS WILL END DURING THE EVENING AND THE
BOUNDARY WILL SLIDE THROUGH THE REGION OVERNIGHT. DRIER AIR
WORKING IN BEHIND IT SHOULD LEAVE VFR CONDITIONS AT KDAY AND
KCMH/KLCK. BUT FURTHER SOUTH THERE COULD BE SOME MIST/FOG AND/OR
STRATUS. HOWEVER CONFIDENCE IS LOW ON LOWER CATEGORY CONDITIONS
ACTUALLY OCCURRING. VFR IS FORECAST TO PREVAIL LATE IN THE TAF
PERIOD WITH FEW TO SCATTERED CUMULUS.

OUTLOOK...THUNDERSTORMS WILL BE POSSIBLE FRIDAY NIGHT THROUGH
SUNDAY.
