NWS Wilmington, OH wrote its last area forecast discussion before this flash flood warning went out at Apr 10, 4:01 PM EDT, 3 hours 16 minutes earlier.

Area forecast discussion, Apr 10, 4:01 PM EDT, 3 hours 16 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
401 PM EDT WED APR 10 2013

.SYNOPSIS...
SHOWERS AND STORMS WILL MOVE ALONG A NEARLY STATIONARY FRONTAL
BOUNDARY ACROSS NORTHERN OHIO TONIGHT. A COLD FRONT WILL APPROACH
LATE TONIGHT AND PUSH THROUGH ON THURSDAY. SHOWERS AND
THUNDERSTORMS WILL ACCOMPANY THE COLD FRONT. COLDER AIR WILL
SETTLE IN BEHIND THE FRONT FOR FRIDAY AND SATURDAY.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
WARM FRONT IS SITUATED JUST NORTH OF OUR AREA THIS AFTERNOON...
STRETCHING FROM NORTHERN INDIANA INTO NORTHERN OHIO. SOUTH OF THE
FRONT ACROSS OUR AREA...TEMPERATURES ARE IN THE UPPER 70S AND
LOWER 80S. CURRENT RADAR TRENDS AND MODEL GUIDANCE HAVE GOOD
PLACEMENT OF NEAR TERM WEATHER FOR TONIGHT. BELIEVE SHRA/TSRA WILL
PERSIST INTO THE EVENING ACROSS THE NORTHWEST WITH MORE WIDELY
SCATTERED/ISOLATED TO THE SOUTH OF CURRENT WATCH. PROBABLY DRY
ACROSS THE SOUTHEAST THROUGH THE NIGHT. COLD FRONT WILL APPROACH
LATE TONIGHT AND AXIS OF PRECIP WILL PUSH INTO THE FAR WEST TOWARD
SUNRISE. TEMPS WILL REMAIN MILD WITH LOWS SLIGHTLY ABOVE GUIDANCE
NUMBERS.

&&

.SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
COLD FRONT WORKS ACROSS AREA THURSDAY AND THEN TO THE EAST
THURSDAY EVENING. THINKING IS DIMINISHING SHRA/TSRA LINE WITH
FRONT IN THE MORNING WITH MODELS SHOWING MORE REDEVELOPMENT ACROSS
THE CWA IN THE AFTERNOON ESPECIALLY IN THE EAST WHERE MORE
WIDESPEAD SIGNIFICANT SEVERE EVENT SHOULD OCCUR WITH ENOUGH
DAYTIME HEATING. TEMPS A BIT TRICKY WITH CLOUDS AND SHRA AND STUCK
CLOSE TO GUIDANCE. SHRA/TSRA TAPERING OFF AND ENDING FROM WEST TO
EAST THURSDAY EVENING. SOME PARTIAL CLEARING. COOLER TEMPS AND
AGAIN CLOSE TO GUIDANCE.

FRIDAY IS CAA WITH CLOUDS RETURNING AND PERHAPS A SPRINKLE OR
LIGHT SHRA. HAVE TROUBLE GOING WITH HIGHER GUIDANCE NUMBERS AND
WILL CONTINUE PREVIOUS FCST TREND OF COOLER HIGHS. FRIDAY NIGHT
LOOKS TO BE ENOUGH CLOUDS AND WIND TO PREVENT ANY SIGNIFICANT
FREEZE OR EVEN FROST AT THIS TIME. WILL NEED TO MONITOR THIS FOR
ANY POSSIBLE HEADLINES NEEDED IN THE SOUTH WITH FROST/FREEZE
PROGRAM STARTED IN THIS AREA ON THURSDAY.

&&

.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
HIGH PRESSURE WILL MOVE ACROSS THE REGION OVER THE WEEKEND.
TEMPERATURES SHOULD BE ABLE TO QUICKLY MODERATE AS FLOW TURNS AROUND
TO THE SOUTH ON SUNDAY. A BROAD UPPER RIDGE WILL REDEVELOP AND
PERSIST INTO MIDWEEK. THIS WILL ALLOW TEMPERATURES TO RISE WELL
ABOVE NORMAL AGAIN. MOISTURE WILL SLOWLY INCREASE AND THIS COULD
EVENTUALLY RESULT IN A FEW SHOWERS AND STORMS IN THE WARM SECTOR.
CHANCE OF STORMS WILL INCREASE LATE TUESDAY INTO WEDNESDAY AS A
SLOW-MOVING FRONTAL SYSTEM APPROACHES THE REGION.

&&

.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
OUR AREA REMAINS IN THE WARM SECTOR THIS AFTERNOON AS THE BOUNDARY
IS JUST OFF TO OUR NORTH...STRETCHING FROM NORTHERN INDIANA INTO
NORTHERN OHIO. SHOWERS AND THUNDERSTORMS HAVE BECOME MORE
WIDESPREAD OFF TO OUR WEST DURING THE PAST HOUR OR SO ALONG AND
SOUTH OF THE BOUNDARY. AIRMASS ACROSS OUR AREA HAS RECOVERED FROM
THE CONVECTION EARLIER THIS MORNING...WITH ML CAPES NOW PUSHING 2000
J/KG. AS A RESULT...SHOWERS AND THUNDERSTORMS OFF TO OUR WEST WILL
LIKELY CONTINUE TO WORK THEIR WAY EAST INTO NORTHERN PORTIONS OF
OUR FA THROUGH MID TO LATE AFTERNOON. EXPECT THE BEST CHANCE TO
REMAIN ACROSS OUR FAR NORTH...CLOSER TO THE BETTER FORCING ALONG
THE FRONT. THIS WILL PUT KDAY...KCMH AND KLCK ON THE EDGE OF SOME
THUNDERSTORM ACTIVITY THROUGH LATE AFTERNOON/EARLY EVENING. STILL
SOME MODEL UNCERTAINTY AS TO HOW FAR IF ANY THE BOUNDARY WILL PUSH
SOUTH OVERNIGHT AND THIS WILL ULTIMATELY AFFECT PCPN CHANCES
LATER TONIGHT. EITHER WAY...THE BEST CHANCE OF PCPN SHOULD REMAIN
NORTH OF THE TAF SITES SO WILL MAINTAIN A DRY FORECAST THROUGH
TONIGHT. MODELS ALSO CONTINUE TO TREND SLOWER WITH THE APPROACH OF
THE COLD FRONT ON THURSDAY. AS A RESULT...THINK WE COULD SEE SOME
PRE FRONTAL SHOWERS WORK INTO THE WEST THROUGH THE MORNING
HOURS...BUT BETTER CHANCE FOR ANY THUNDERSTORMS SHOULD HOLD OFF
UNTIL THURSDAY AFTERNOON.

OUTLOOK...MVFR CEILINGS POSSIBLE THURSDAY NIGHT INTO FRIDAY.
