AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
447 PM EDT TUE MAY 26 2015

.SYNOPSIS...
A WARM AND HUMID AIRMASS WILL REMAIN IN PLACE OVER THE NEXT FEW
DAYS. MULTIPLE DISTURBANCES WILL BRING SEVERAL ROUNDS OF SHOWERS
AND THUNDERSTORMS TO THE REGION THROUGH THE WEEK.

&&

.NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/...
SHOWERS AND THUNDERSTORMS HAVE DEVELOPED IN AN UNSTABLE AIRMASS
THIS AFTERNOON. THE MAIN SEVERE THREAT IS EXPECTED TO BE DAMAGING
WINDS. LOW LEVEL SHEAR IS NOT THAT IMPRESSIVE AND LCL HEIGHTS ARE
NOT VERY LOW. DUE TO THIS NOT EXPECTING MUCH OF A TORNADO THREAT.
FREEZING LEVELS ARE QUITE HIGH. ALTHOUGH SMALL HAIL WILL BE
POSSIBLE NOT EXPECTING MUCH IN THE WAY OF LARGE HAIL WITH THIS
SYSTEM. SEVERE THREAT WILL TAPER OFF LATER THIS EVENING HOWEVER
SOME RESIDUAL SHOWER AND THUNDERSTORM ACTIVITY WILL LINGER INTO
THE OVERNIGHT HOURS. WENT CLOSE TO GUIDANCE FOR LOW TEMPERATURES
TONIGHT WITH LOWS IN THE MID 60S. GUSTY WINDS THROUGH THE EVENING
HOURS WILL DECREASE OVERNIGHT AS WELL.

&&

.SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/...
DRY CONDITIONS ARE EXPECTED FOR THE START OF THE SHORT TERM. A
FRONTAL BOUNDARY WILL APPROACH THE AREA WEDNESDAY AFTERNOON. THIS
SYSTEM WILL WEAKEN WEDNESDAY EVENING AS IT CONTINUES TO MOVE
THROUGH THE AREA. THERE IS THE POTENTIAL FOR ISOLATED STRONG TO
SEVERE STORMS...PRIMARILY ACROSS NW PORTIONS OF THE FA. AS THE
FRONTAL BOUNDARY SAGS SOUTH SHOWER AND THUNDERSTORM ACTIVITY WILL
TAPER OFF ACROSS NORTHERN PORTIONS OF THE FA WEDNESDAY NIGHT. SOME
LINGERING ACTIVITY WILL REMAIN ACROSS EXTREME SOUTHERN PORTIONS OF
THE FA BY THE END OF THE SHORT TERM.

WARM SOUTHERLY FLOW WILL ALLOW FOR TEMPERATURES TO CLIMB INTO THE
80S AGAIN FOR THE DAY ON WEDNESDAY. TEMPERATURES WILL DROP DOWN
INTO THE 60S WEDNESDAY NIGHT.

&&

.LONG TERM /THURSDAY THROUGH TUESDAY/...
AN UNSETTLED PATTERN IS FORECAST TO PERSIST THROUGH THE PERIOD.

PERIOD STARTS WITH AN UPPER RIDGE IN PLACE. A HUMID AND UNSTABLE
AIRMASS CIRCULATING AROUND A SURFACE HIGH CENTERED TO THE EAST WILL
RESULT IN A CHANCE OF THUNDERSTORMS ON THURSDAY MAINLY OVER
SOUTHEAST COUNTIES. SIMILAR CONDITIONS FRIDAY MAY RESULT IN A FEW
MORE THUNDERSTORMS...POSSIBLY AIDED BY COOLING ALOFT AS THE UPPER
RIDGE BEGINS TO ERODE.

ORGANIZED AND WIDESPREAD CONVECTION WILL BE POSSIBLE SATURDAY
THROUGH MONDAY WHEN A SLOW MOVING FRONTAL BOUNDARY IS PUSHED
SOUTHEASTWARD TO ILN BY A BROAD UPPER TROUGH. THE CHANCE FOR
THUNDERSTORMS WILL PERSIST OVER PARTS OF THE AREA ON TUESDAY WHEN
THE FRONTAL BOUNDARY IS PROGGED TO LINGER TO THE SOUTH.

WARM CONDITIONS WITH HIGHS IN THE 80S ARE IN STORE FOR THURSDAY
THROUGH SATURDAY IN A SOUTHERLY FLOW AHEAD OF THE FRONT. READINGS IN
THE 70S ARE EXPECTED SUNDAY THROUGH TUESDAY IN THE COOLER AIRMASS
BEHIND THE FRONT.

&&

.AVIATION /20Z TUESDAY THROUGH SUNDAY/...
CONVECTION DEVELOPING ACROSS THE REGION WILL POTENTIALLY AFFECT
ALL TERMINALS DURING THE EARLY PART OF THE TAF PERIOD. HEAVIEST
DOWNPOURS COULD BRIEFLY REDUCE VISIBILITY TO IFR. BUT FELT THAT
MVFR CONDITIONS WITH THE STORMS WAS MORE LIKELY. SOME SHOWERS OR
POSSIBLY THUNDERSTORMS COULD LINGER AFTER 00Z. BUT AT THIS POINT
THE POTENTIAL WAS LOW ENOUGH TO NOT HAVE FURTHER MENTION WITHIN
THE TAFS.

GUIDANCE IS SUGGESTING THAT LOW LEVEL MOISTURE WILL INCREASE LATE
TONIGHT. SIGNALS ARE MIXED ON WHETHER THAT WILL MANIFEST ITSELF
AS CLOUDS OR MIST OR BOTH. FORECAST CONTINUES WITH STRATUS AROUND
MVFR/IFR THRESHOLD. EXCEPTION IS FOR CINCINNATI TERMINALS WHERE
MIST/FOG MAY BE A BETTER POSSIBILITY.

OUTLOOK...THUNDERSTORMS POSSIBLE WEDNESDAY AFTERNOON AND EVENING
AND AGAIN SATURDAY INTO SUNDAY.
