AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE WILMINGTON OH
732 AM EDT SUN OCT 6 2013
.SYNOPSIS...
A STRONG LOW PRESSURE CENTER AND COLD FRONT WILL BRING WIDESPREAD
SHOWERS AND THUNDERSTORMS WITH HEAVY RAIN TO THE AREA TODAY INTO
TONIGHT. MUCH COOLER AIR WILL MOVE IN BEHIND THE FRONT MONDAY.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
MODELS ARE IN GOOD AGREEMENT WITH THE SETUP FOR TODAY AS THEY DIG
A DEEP H5 LOW INTO THE PLAINS TODAY. AHEAD OF THE H5 LOW...A CDFNT
IS SLOWLY MOVG UP THE OH VALLEY. PCPN AHEAD OF THE FRONT WILL
PROGRESS EWD VERY SLOWLY INITIALLY TODAY. DEEP MOISTURE IS BEING
PULLED NORTHWARD INTO THE ACROSS OUR AREA. CONSIDERING THE
TROPICAL NATURE OF THE AIRMASS AND PW VALUES OVER 200 PERCENT OF
NORMAL...WILL CONTINUE THE FLOOD WATCH ACROSS THE WRN HALF OF THE
FA. FARTHER E...PCPN WILL TAKE A WHILE TO WORK IN AND AT THIS TIME
DONT THINK THAT THE FLOODING THREAT IS THERE TO EXPAND THE FLOOD
WATCH FOR THE TODAY PERIOD.
SPC HAS THE A PORTION OF THE REGION UNDER A SLIGHT RISK OF SEVERE
WEATHER TODAY. ALTHOUGH THE WIDESPREAD PCPN TODAY SHOULD HELP KEEP
INSTABILITY DOWN ACROSS THE REGION...THERE COULD BE AREAS WHERE
SFC TEMPS CAN WARM...WHICH WOULD INCREASE THE CHANCE OF A SVR CELL.
IN ADDITION...MODERATE DEEP LAYER SHEAR WITH 30-40 KT OF LOW-LEVEL
FLOW MAY BE ENOUGH FOR AN ISOLATED WIND DAMAGE.
AS FOR TEMPERATURES...EXPECT A WIDE RANGE IN HIGHS TODAY. UPPER
60S IN THE WHITEWATER VALLEY TO THE LOWER 80S ACROSS THE ERN COUNTIES.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH TUESDAY/...
MODELS REMAIN CONSISTENT WITH THE TIMING OF THE FRONT AND PRECIPITATION
TONIGHT AS THEY BEGIN TO ACCELERATE THEM EASTWARD. THIS SHOULD
HELP KEEP THE PCPN DOWN ENUF IN THE EAST TO NOT ISSUE A FLOOD
WATCH ANY FARTHER EAST. THE NAM IS THE SLOWEST WITH THE BACK EDGE
OF THE BAND. WENT WITH THE SLIGHT FASTER GFS/ECMWF SOLUTION...SO
HAVE THE BULK OF THE PCPN ENDING THE W AROUND MIDNIGHT...WITH IT
JUST ABOUT TO EXIT THE REGION AT SUNRISE MONDAY.
MUCH COLDER AIR WILL PUSH INTO THE REGION BEHIND THE FRONT MONDAY.
THE NAM IS THE DEEPEST AND FURTHEST S WITH THE H5 LOW ON MONDAY.
PREFER THE QUICKER AND LESS DEEP GFS/ECMWF DEPICTION OF THE
EJECTING LOW FOR MONDAY. EXPECT TO SEE SOME SCATTERED INSTABILITY
SHOWER DEVELOPMENT THROUGH LATE MORNING AND INTO THE AFTERNOON. THE
BEST CHANCE WILL BE ACROSS OUR NORTHERN AREAS...CLOSER TO THE
CENTER OF THE UPPER LEVEL LOW. H8 CAA WILL CONTINUE INTO MONDAY
AFTERNOON WITH H8 TEMPERATURES BETWEEN 0 TO 4 C. THIS WILL LIMIT
WARMING AND WILL KEEP HIGHS ONLY EXPECTED TO BE IN THE UPPER 50S
TO LOWER 60S.
A SFC HIGH WILL THEN BEGIN TO BUILD IN MONDAY NIGHT INTO TUESDAY.
SKIES WILL GRADUALLY CLEAR MONDAY NIGHT. SOME LINGERING H8 CAA SHOULD
POP A FEW CU ON TUESDAY. LOWS MONDAY NIGHT WILL DROP INTO THE
LOWER TO MID 40S...WITH HIGHS GETTING BACK INTO THE 60S ON TUESDAY.
&&
.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
MID LEVEL RIDGING WILL BEGIN TO BUILD IN FROM THE WEST THROUGH THE
DAY ON TUESDAY AND THEN REMAIN IN PLACE ACROSS THE REGION THROUGH
THE REMAINDER OF THE WEEK. THIS WILL ALLOW FOR SURFACE HIGH PRESSURE
TO SHIFT SLOWLY EAST ACROSS OUR AREA AND SET UP OVER THE
NORTHEASTERN UNITED STATES THROUGH THE END OF THE LONG TERM
PERIOD. AS THE AIRMASS SLOWLY MODIFIES AND WE SLOWLY GET INTO MORE
RETURN FLOW...WE SHOULD SEE A GRADUAL WARM UP IN TEMPERATURES
TOWARD THE END OF THE WEEK WITH HIGHS PUSHING BACK UP INTO THE
LOWER 70S.
&&
.AVIATION /12Z SUNDAY THROUGH THURSDAY/...
DIFFICULT TO ASSESS TIMING OF MVFR AND EVEN IFR TIMING...BETWEEN
SHOWERS...TAF LOCATIONS GENERALLY VFR TO HIGH MVFR CIGS AND
VSBYS...WITH AS HEAVIER BANDS OF SHOWERS OR TSTMS...VSBYS QUICKLY
BUT BRIEFLY DROP TO 2 SM ALONG WITH IFR CIGS. WITH NOTHING TO
REALLY PUSH ALONG THE UPR LOW...THE ASSOCIATED SFC BOUNDARY STILL
FAIRLY SLOW TO MOVE ALONG...WITH PERIODS OF SHRA/TSTMS UNTIL ABOUT
22Z AND THEN THE PUSH BEGINS ACROSS THE AREA. BEHIND THE
PRECIPITATION ENDING IN THE 03-05Z TIMEFRAME...GENERALLY VFR CIGS.
OUTLOOK...SHOWERS AND MVFR CONDITIONS POSSIBLE THROUGH MONDAY
MORNING.
