AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
436 PM EDT THU APR 2 2015

.SYNOPSIS...
A COLD FRONT WILL DROP SOUTH INTO THE OHIO VALLEY AND REMAIN ACROSS
THE AREA THROUGH FRIDAY. SEVERAL WAVES OF LOW PRESSURE TRAVELING
ALONG THE FRONT WILL PROVIDE MULTIPLE ROUNDS OF STORMS. HIGH PRESSURE
AND DRIER AIR WILL MOVE BACK IN FOR SATURDAY INTO SUNDAY.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
BROAD MOIST SOUTHWESTERLY MID LEVEL FLOW WITH SLOW MOVING COLD FRONT
DROPPING INTO OHIO OVERNIGHT. MARGINAL INSTBY HAS DEVELOPED INTO
SW OHIO. STORMS OVER THE LOWER OHIO VALLEY ARE DEVELOPING INTO A
LINE. WIND FIELDS AND WET BULB ZERO HEIGHTS SUGGEST THAT SOME OF
THE STRONGER UPDRAFTS WILL BE CAPABLE OF PRODUCING LARGE HAIL AND
DAMAGING WINDS EARLY THIS EVENING.

CONVECTIVE ENABLING MODELS SHOW SUGGEST THAT THIS COLD POOL DRIVEN
CONVECTION DEVELOPS INTO ILN/S SW FA IN RGN OF FAVORABLE LOW LEVEL
CONVERGENCE INTO THIS EVENING. EXPECT ADDITIONAL STORMS TO COME
TOGETHER AHEAD OF THE SFC COLD FRONT BETWEEN 06Z AND 12Z IN NEXT
REGION OF FAVORABLE LOW LEVEL CONVERGENCE.

IN FAVORABLE MOISTURE TRANSPORT PW/S TO INCREASE TO AROUND 250
PERCENT OF NORMAL OR 2 TO 3 STD DEVIATIONS ABOVE NORMAL. DUE TO
PROLONGED PERIOD OF PCPN AND VERY MOIST ENVIRONMENT...EXPECT 1 TO
3+ INCHES OF RAINFALL THRU FRIDAY. WILL CONTINUE FLOOD WATCH
TONIGHT INTO FRIDAY.

GOOD GRADIENT TO TEMPERATURES WITH FRONT BISECTING THE AREA. LOWS
FROM THE MID/UPR 40S NW TO UPPER 50S SE.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH SATURDAY NIGHT/...
BROAD SOUTHWESTERLY MID LEVEL FLOW WITH SLOW MOVING FRONT DROPPING
SOUTH THRU ILN/S FA FRIDAY WITH H5 TROF SETTLING INTO GREAT
LAKES/OH VLY FRIDAY NIGHT. VERY MOIST ENVIRONMENT TO CONTINUE
ACROSS THE SOUTH WITH PW/S IN EXCESS OF 200 PERCENT OF NORMAL.
AXIS OF FAVORABLE LOW LEVEL FORCING TO BECOME ENHANCED WITH 8H
TROF DROPPING THRU FA FRIDAY AFTN/FRIDAY EVENING. SIGNIFICANT SFC
WAVE TO RIPPLE NE THRU THE FA FRIDAY EVENING. FRONT/SFC LOW
BISECTING FA WILL LEAD TO GOOD TEMPERATURES GRADIENT WITH FRIDAYS
HIGHS RANGING FROM MID 50S NW TO THE UPPER 60S SE.

DEEP MOISTURE AND LIFT TO PIVOT EAST OF ILN/S FRIDAY NIGHT. THERE
MAY BE A VERY BRIEF PERIOD OF RAIN/SNOW MIX PRIOR TO ENDING AS
COLDER AIR IS FUNNELED IN. ANY SNOW WILL BE MINIMAL AND ONLY HAVE
UP TO A TENTH OF AN INCH OVER EXTREME NE. LOWS FRIDAY NIGHT TO
RANGE FROM NEAR 30 NW TO THE UPPER 30S SE.

NW FLOW ALOFT WITH SFC HIGH PRESSURE BUILDING IN SATURDAY. EXPECT
DECREASE IN CLOUDS WITH A GOOD DEAL OF SUNSHINE SATURDAY. ALTHOUGH
SKIES WILL BE MOSTLY SUNNY...TEMPERATURES WILL BE 5 TO 10 DEGREES
BELOW NORMAL WITH HIGHS RANGING FROM THE UPPER 40S NW TO THE LOWER
50S SE.

THIS SFC HIGH TO BUILD ACRS THE AREA SAT NIGHT WITH MOSTLY CLEAR
SKY CONDITIONS AND LIGHT WINDS. LOWS TO RANGE FROM THE LOWER 30S
EAST TO THE MID/UPR 30S WEST.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
DRY WEATHER IS EXPECTED SUNDAY AS HIGH PRESSURE MOVES EAST. FOR
MONDAY THROUGH THURSDAY...THE ACTIVE PATTERN WILL RETURN. A FRONTAL
BOUNDARY CONTAINING ABUNDANT MOISTURE WILL DEVELOP MONDAY NEAR THE
WESTERN GREAT LAKES. MODELS ARE IN GOOD AGREEMENT THAT THE FRONT
WILL FORM...BUT THE LOCATION...TIMING AND DURATION OF PRECIPITATION
IS IN QUESTION. A FEW SHOWERS MAY OCCUR MONDAY IN MOISTURE ADVECTION
AND SHORT WAVE ENERGY SOUTH OF THE BOUNDARY. SHOWERS AND
THUNDERSTORMS WILL BECOME LIKELY ON TUESDAY WHEN THE FRONT IS
FORECAST TO SAG SOUTH TOWARD OHIO. THERE WILL BE A GOOD CHANCE FOR
SHOWERS WEDNESDAY AND THURSDAY IN THE PERSISTENTLY MOIST REGIME
ASSOCIATED WITH THE UNDULATING FRONT.

TEMPERATURES WILL START OUT NEAR NORMAL SUNDAY WITH HIGHS IN THE
LOWERS 60S. IT MAY BE A COUPLE DEGREES COOLER MONDAY UNDER WEAK COLD
ADVECTION. TUESDAY IS SHAPING UP TO BE THE WARMEST DAY IN THIS
PERIOD WHEN WARM ADVECTION MAY BOOST READINGS TO AROUND 70. A RETURN
TO NEAR NORMAL LOWER 60S APPEARS TO BE IN STORE FOR WEDNESDAY AND
THURSDAY IN AN ENVIRONMENT OF LIMITED SUNSHINE AND COLD ADVECTION.

&&

.AVIATION /20Z THURSDAY THROUGH TUESDAY/...
A COMPLEX WEATHER SITUATION CAN BE EXPECTED ACROSS THE REGION
TODAY THROUGH FRIDAY NIGHT.

FOR THIS AFTERNOON INTO THIS EVENING...THE TIMING OF SHOWERS AND
THUNDERSTORMS WILL BE SOMEWHAT DIFFICULT GIVEN THAT HIGH
RESOLUTION MODELS ARE DOING A POOR JOB GIVEN CURRENT RADAR MOSAIC
AND THEREFORE THE TIMING OF FUTURE CONVECTION AND WHEN IT WILL
MOVE ACROSS THE TAF STIES HAS SOME UNCERTAINTY. WARM...MOIST AIR
CONTINUES TO FUNNEL NORTHEAST INTO THE REGION AHEAD OF AN
ADVANCING COLD FRONT. THIS MOISTURE IS CURRENTLY INTERACTING WITH
AN EMBEDDED DISTURBANCE WHICH IS PRODUCING SHOWERS AND A FEW
THUNDERSTORMS. THE POTENTIAL FOR MORE ROBUST SHOWERS AND
THUNDERSTORMS SHOULD COME LATE THIS AFTERNOON INTO THIS EVENING
WHEN GREAT INSTABILITY AND PREFRONTAL CONVERGENCE DEVELOPS ALONG
AND AHEAD OF FRONT...WITH PRECIPITATION LIKELY PROPAGATING AWAY
FROM THE FRONTAL BOUNDARY. HAVE PLACED TEMPO TSRA IN ALL TAF SITES
WITH SOME MVFR CEILINGS/LOCAL IFR VISIBILITIES POSSIBLE.

FOR THE OVERNIGHT PERIOD...FRONTAL BOUNDARY WILL SAG SOUTHEAST AND
SHOULD STALL NEAR THE OHIO RIVER. A LOW LEVEL JET IN ASSOCIATION
WITH ANOTHER DISTURBANCE ALOFT WILL PRODUCE MORE SHOWERS...AND
PERHAPS A FEW THUNDERSTORMS...MAINLY ALONG AND SOUTH OF THE OHIO
RIVER. MODERATE TO LOCALLY HEAVY RAIN WILL BE POSSIBLE. A
SATURATED AIRMASS AND NIGHT TIME COOLING WILL LIKELY ALLOW
CEILINGS TO DROP INTO THE IFR CATEGORY.

FOR FRIDAY...MORE DIGGING ENERGY FROM THE NORTHWEST WILL PERTURB A
WAVE OF LOW PRESSURE ALONG STALLED BOUNDARY WHICH WILL MOVE
NORTHEAST ACROSS THE OHIO RIVER VALLEY. SHOWERS AND PERHAPS A FEW
THUNDERSTORMS CAN BE EXPECTED. MODERATE TO LOCALLY HEAVY RAIN WILL
CONTINUE TO BE A THREAT...ESPECIALLY ALONG AND SOUTH OF THE OHIO
RIVER. IFR CEILINGS IN THE MORNING SHOULD LIFT TO MVFR.
VISIBILITIES WILL RANGE BETWEEN MVFR AND IFR IN MODERATE TO LOCALLY
HEAVY RAIN.

OUTLOOK...MVFR AND POSSIBLY IFR CEILINGS AND VISIBILITIES
CONTINUING INTO FRIDAY NIGHT. MVFR CEILINGS AND VISIBILITIES
POSSIBLE MONDAY INTO TUESDAY.
