AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
402 PM EDT TUE SEP 10 2013
.SYNOPSIS...
HIGH PRESSURE SOUTH OF THE OHIO VALLEY AND A SOUTHWEST FLOW AT THE
SURFACE WILL KEEP HOT AND HUMID CONDITIONS THROUGH WEDNESDAY NIGHT. A
COLD FRONT WILL PUSH THROUGH ON THURSDAY...SPARKING SOME SHOWERS AND
THUNDERSTORMS. MUCH MORE SEASONABLY COOLER AND DRIER AIR WILL
SETTLE IN BEHIND THE FRONT FOR THE END OF THE WEEK.
&&
.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
NICE CELL POPPED UP SOUTH OF INDIANAPOLIS AND WEST OF RIPLEY
COUNTY THIS AFTERNOON. WITH THE FLOW BEING MARGINALLY TO THE EAST-
NORTHEAST...THERE MAY BE SOME STORMS WORKING INTO THE WHITEWATER
VALLEY AND ILN CWA THIS LATE AFTERNOON AND EARLY EVENING. LOW
CHANCE/ISOLATED POPS ARE IN THE FORECAST THIS EVENING GENERALLY
SOUTH OF THE I-70 CORRIDOR WITH HIGHER CHANCES ALONG THE IND/ILN
BORDER.
TEMPERATURES TOPPING INTO THE UPPER 90S NORTH OF DAYTON ARE ONLY
METED BY LOWER DEWPOINTS IN THE LOW TO MID 60S. HIGHER DEWPOINTS
WITH SLIGHTLY "COOLER" AIR ELSEWHERE ARE NUDGING APPARENT
TEMPERATURES TOWARDS ADVISORY VALUES AND THE ADVISORY WILL
CONTINUE INTO THE EARLY EVENING TODAY.
&&
.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/...
OUTSIDE OF THE THUNDERSTORM WEST OF CINCINNATI...CU FIELD SHOULD
DISSIPATE RELATIVELY QUICKLY WITH NIGHTFALL. SOUTHWEST FLOW WILL
KEEP OPPRESSIVELY WARM AND HUMID AIR OVER THE REGION TONIGHT AND
WEDNESDAY NIGHT.
A SLIGHTLY HIGHER CHANCE FOR THUNDERSTORMS TOMORROW LED TO COOLER
HIGHS IN THE LOWER 90S. THIS WILL HAVE THE HIGHEST POTENTIAL FOR
CHANGE - IF THE STORMS HOLD OFF...ANOTHER ADVISORY WILL BE IN
ORDER FOR WEDNESDAY AND HIGHS WILL NEED TO BE BUMPED BY 2-4
DEGREES ACROSS THE BOARD.
WITH THE FROPA LATE WED NIGHT AND EARLY THURSDAY...DRIER AND
COOLER AIR WILL ENTER THE OHIO VALLEY TO WIND DOWN THE WORK WEEK.
WHILE HIGHEST CHANCE FOR RAIN IS ON THURSDAY...I DID NOT FEEL
COMFORTABLE WITH LIKELY AT THIS TIME AND KEPT MOST OF THE AREA IN
THE HIGH END OF THE CHANCE CATEGORY. HIGHS ON THURSDAY WILL BE
NICELY MUTED WITH COLD AIR WORKING IN...CLOUD COVER...AND
INCREASED POTENTIAL FOR SHOWERS AND THUNDERSTORMS.
&&
.LONG TERM /FRIDAY THROUGH TUESDAY/...
MID LEVEL SHORT WAVE ENERGY WILL ROTATE DOWN ACROSS THE LOWER GREAT
LAKES ON FRIDAY. THIS WILL BE ACCOMPANIED BY DEVELOPING LOW LEVEL
CAA ACROSS OUR AREA AS 850 MB TEMPS ARE FORECAST TO DROP INTO THE 3
TO 5 DEGREE CELSIUS RANGE THROUGH FRIDAY AFTERNOON. THIS SHOULD LEAD
TO SOME CU DEVELOPMENT THROUGH THE DAY AND PERHAPS EVEN A SHOWER OR
TWO...ESPECIALLY ACROSS OUR NORTHEASTERN AREAS. WILL MAINTAIN A DRY
FORECAST THOUGH AS THE BETTER FORCING REMAINS WELL OFF TO OUR
NORTHEAST. LOW LEVEL THICKNESSES ARE ONLY SUPPORTING HIGHS IN THE
LOW TO MID 60S FOR FRIDAY. WILL NOT GO THAT COOL...BUT WILL TREND
TEMPS DOWN A BIT...GENERALLY IN THE 65 TO 70 DEGREE RANGE. SURFACE
HIGH PRESSURE WILL BUILD ACROSS THE AREA FRIDAY NIGHT AND SHOULD BE
CENTERED JUST OFF TO OUR NORTHWEST BY 12Z SATURDAY MORNING. THIS
WILL ALLOW FOR GOOD RADIATIONAL COOLING AND EXPECT FRIDAY
NIGHT/SATURDAY MORNING TO BE OUR COOLEST NIGHT WITH LOWS WELL DOWN
INTO THE 40S...ESPECIALLY ACROSS SOME OF OUR NORTHERN RURAL AREAS.
THE SURFACE HIGH WILL PUSH OFF TO THE EAST SATURDAY INTO SUNDAY.
THIS WILL ALLOW FOR DRY CONDITIONS AND A GRADUAL WARM UP THROUGH THE
WEEKEND WITH HIGHS WORKING BACK INTO THE MID 70S BY SUNDAY. THE NEXT
MID LEVEL SHORT WAVE WILL PUSH ACROSS THE GREAT LAKES SUNDAY NIGHT
INTO MONDAY. THIS WILL HELP DROP AN ASSOCIATED WEAKENING FRONT DOWN
INTO OUR AREA THROUGH MONDAY. THE 12Z ECMWF HAS TRENDED WEAKER WITH
THIS FRONT AND IS NOW MORE IN LINE WITH WHAT IS SUGGESTED BY THE
GFS/CMC. AS A RESULT...WILL TRIM BACK TO JUST SOME VERY LOW END POPS
FOR SUNDAY NIGHT INTO MONDAY MORNING. WEAK MID LEVEL RIDGING WILL
TRY TO REESTABLISH ITSELF ACROSS THE AREA THROUGH THE MIDDLE PART OF
NEXT WEEK AS SURFACE HIGH PRESSURE MOVES ACROSS THE SOUTHERN GREAT
LAKES. THIS SHOULD KEEP US GENERALLY DRY WITH TEMPERATURES
REMAINING SOMEWHAT BELOW NORMAL THROUGH THE END OF THE PERIOD.
&&
.AVIATION /20Z TUESDAY THROUGH SUNDAY/...

TODAY. IN THE MOIST SRLY FLOW...MID LEVEL CLOUDS 7000 AND 9000
