Severe Thunderstorm Warning 43, NWS Wilmington, OH

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
201 PM EDT WED MAY 14 2014

.SYNOPSIS...
A SLOW MOVING FRONTAL BOUNDARY WILL BE THE FOCUS FOR SHOWER AND
THUNDERSTORM DEVELOPMENT TODAY AND TONIGHT...AIDED BY WAVES OF LOW
PRESSURE TRAVELING ALONG THE FRONT. AN UPPER TROUGH FOLLOWING THE
FRONT WILL BRING COOLER TEMPERATURES AND A FEW SHOWERS FOR THE
WEEKEND.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
INITIAL WAVE OF CONVECTION AHEAD OF EMBEDDED H5 VORT MAXS IS
LIFTING THRU THE FA ATTM. EXPECT THE SE COUNTIES TO BE WARM
SECTORED FOR THE NEXT SEVERAL HOURS...WHICH WILL ALLOW IT TO WARM
QUICKLY AND DESTABILIZE. SHOULD SEE REDEVELOPMENT IN THE SOUTHEAST
COUNTIES DURING THE AFTN. FARTHER WEST ALONG THE OHIO/INDIANA
BORDER ON THE COOL SIDE OF THE FRONT...EXPECT SHRA AND EMBEDDED
TSRA TO CONTINUE TO LIFT N THROUGH THE DAY.

METEOROLOGICAL SETUP IS STILL THERE FOR SEVERE WEATHER THIS
AFTERNOON. THE MOISTURE AND LIFT ASSOCIATED WITH AN APPROACHING LOW
AND THE CDFNT WILL COMBINE WITH VERY STRONG AND DEEP JET STREAM.
ADD IN BACKING SFC WINDS TO HELP WITH THE SHEAR.

UPPED HIGH A FEW DEGREES SE OF I-71 FOR THIS AFTERNOON DUE TO THE
ADDED SUNSHINE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/...
WAVE OF LOW PRESSURE IS FORECAST TO TRAVEL NORTHWARD ALONG THE
FRONT TONIGHT. LATEST MODELS SHOW THE LOW NEAR THE OHIO-INDIANA
BORDER 06Z TO 12Z THURSDAY. THIS PATTERN WILL BRING PERIODS OF
SHOWERS AND THUNDERSTORMS. STRONG WIND FIELDS WILL CARRY COPIOUS
MOISTURE NORTHWARD...AND WILL CONTRIBUTE TO THUNDERSTORM
ORGANIZATION. THIS PATTERN WILL RESULT IN HEAVY DOWNPOURS AND
POSSIBLY LOCALIZED FLOODING...AND STRONG TO SEVERE THUNDERSTORMS
CAPABLE OF PRODUCING DAMAGING WINDS AND LARGE HAIL. TURNING OF
WINDS WITH HEIGHT MAY ALSO ALLOW ISOLATED TORNADOES TO FORM.

FRONT IS PROGGED TO MOVE EAST ON THURSDAY. THREAT OF SEVERE
WEATHER AND HEAVY RAIN WILL END AS SHOWERS AND THUNDERSTORMS
DIMINISH FROM WEST TO EAST.

AN UNUSUALLY DEEP UPPER TROUGH AND COOL NORTHWEST LOW LEVEL FLOW
FOLLOWING THE FRONT WILL PROVIDE A CHANCE OF SHOWERS AND BELOW
NORMAL TEMPERATURES THROUGH FRIDAY. HIGHS IN THE 60S ARE EXPECTED
THURSDAY AND FRIDAY...WITH LOWS DROPPING TO AROUND 40 THURSDAY
NIGHT.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
AN UPPER LEVEL LOW WILL ROTATE SLOWLY EAST ACROSS THE GREAT LAKES
REGION THROUGH THE WEEKEND AS A BROADER MID/UPPER LEVEL TROUGH
SHIFTS EAST ACROSS THE EASTERN CONUS. THIS WILL KEEP A SEASONABLY
COOLER AIRMASS IN PLACE ACROSS OUR REGION THROUGH AT LEAST THE
WEEKEND. A SERIES OF SHORT WAVES WILL ROTATE AROUND THE UPPER
LOW...BRINGING OCCASIONAL CHANCES OF PCPN INTO SATURDAY. IT LOOKS
LIKE THE FIRST SHORT WAVE WILL PIVOT UP ACROSS OUR AREA LATE
THURSDAY NIGHT THROUGH FRIDAY MORNING WITH PERHAPS A WEAKER ONE
AFFECTING OUR AREA DURING THE DAY ON SATURDAY. WITH THE COOLER AIR
MASS IN PLACE...WOULD EXPECT A DIURNAL INFLUENCE WITH THE SHOWER
ACTIVITY AND WILL TRY TO HINT AT THIS IN THE GRIDS FOR BOTH FRIDAY
AFTERNOON AND SATURDAY AFTERNOON. INCREASING LOW LEVEL LAPSE RATES
DURING THE DAY WILL RESULT IN SOME WEAK INSTABILITIES SO TOUGH TO
RULE OUT A FEW THUNDERSTORMS...BUT THINK CHANCE IS LOW ENOUGH TO
KEEP MENTION OUT OF FORECAST AT THIS POINT. WILL TREND
TEMPERATURES ON THE COOLER SIDE WITH HIGHS ONLY IN THE UPPER 50S
TO LOWER 60S BOTH FRIDAY AND SATURDAY.

UPPER LEVEL RIDGING WILL PROGRESSES SLOWLY EAST ACROSS THE CENTRAL
UNITED STATES THROUGH EARLY NEXT WEEK...LEADING TO GRADUAL HEIGHT
RISES ACROSS OUR AREA. THIS WILL ALLOW FOR A SLOW WARM UP EACH
DAY...WITH TEMPERATURES CLIMBING BACK UP CLOSER TO NORMAL BY
TUESDAY. AS THE RIDGE WORKS EAST...WE WILL GET INTO A PERIOD OF
NORTHWEST FLOW ALOFT. THIS MAY EVENTUALLY LEAD TO SOME PCPN
CHANCES...BUT WITH THE MODELS NOT REALLY SHOWING MUCH IN THE WAY OF
SHORT WAVE ENERGY...WILL MAINTAIN A DRY FORECAST FOR THE TIME BEING.

&&

.AVIATION /18Z WEDNESDAY THROUGH MONDAY/...
ATMOSPHERE CONTINUES TO DESTABILIZE TO THE S AND E OF THE TAFS WHEN
SUNSHINE HAS BEEN ABUNDANT. TO THE NW OF I-71...IFR ST DECK HAS
THE KDAY TAF SOCKED IN. BOUNDARY IS EXPECT TO BUCKLE TO THE N THIS
AFTN. THIS SHOULD ALLOW KCVG/KLUK AND KILN TO GO VFR.

ADDITIONAL CONVECTION SHOULD WORK INTO THE TAFS FROM SOUTH CENTRAL
KY AHEAD OF A LOW PRESSURE WAVE.

AS THE H5 TROF BEGINS TO LIFT OUT TONIGHT A STRONGER SFC LOW
DEVELOPS IN THE LOWER OHIO VALLEY. THIS LOW SWINGS THE FRONT EWD
TONIGHT. A MORE SOLID AREA OF CONVECTION IS EXPECTED AHEAD OF THIS
FRONT. IFR/MVFR CONDITIONS WILL BE POSSIBLE. AS THE FRONT SWINGS THRU
LATE IN THE PERIOD...IFR CIGS WILL BE POSSIBLE POST FRONTAL.

OUTLOOK...MVFR CEILING AND VISIBILITIES POSSIBLE AGAIN FRIDAY
AFTERNOON INTO FRIDAY NIGHT.

&&
