AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 404 PM EDT TUE JUN 26 2007 .SYNOPSIS... A WEAK MID LEVEL DISTURBANCE OVER THE MID MISSISSIPPI VALLEY MAY SPARK A FEW THUNDERSTORMS ACROSS THE REGION INTO THIS EVENING. MID LEVEL RIDGING WILL BRIEFLY BUILD INTO THE OHIO VALLEY AHEAD OF AN APPROACHING COLD FRONT. THE COLD FRONT WILL SAG INTO THE REGION THURSDAY BRINGING A GOOD CHANCE FOR WIDESPREAD SHOWERS AND THUNDERSTORMS. RYAN && .NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/... FCST AREA IN BTWN REMNANTS OF MID LVL DISTURBANCE OVER ILLINOIS AND WRN INDIANA AND A WEAK VORT PASSING THRU SE OHIO. BOTH OF THESE FEATURES WERE CONTRIBUTING TO SCT TSTM DVLPMNT...WITH MORE ROBUST CONVECTION TO WEST OF REGION. ADDITIONALLY ACRS CNTRL/NRN KY...A WEAK CONV BNDRY APPEARED TO BE MAIN CONTRIBUTOR TO SCT CONVECTIVE DVLPMNT. UNDER MORE SUNSHINE TODAY...TEMPS HAD WARMED INTO U80S/L90S. WITH EXCEPTION OF SCT CONVECTION ACRS NRN KY/SO CNTRL OH AND A FEW ROGUE CELLS NE OF CMH METRO...MUCH OF FCST AREA REMAINS PCPN FREE WITH MID LVL NVA SUPPRESSING CONVECTIVE POTENTIAL. MID LVL NVA HOLDS ACRS REGION INTO EVNG HOURS AS WEAK VORT TO SE OF REGION SLOWLY PULLS AWAY TO THE EAST. STRONGER VORT IN ASSOC WITH MID LVL DISTURBANCE WILL STAY WEST OF REGION INTO THE EVNG...WITH MUCH OF THE TSTM ACTIVITY OVER WRN/CNTRL INDIANA LIKELY TO NOT MAKE IT INTO FCST AREA BEFORE DYING OUT. WILL PLACE HIGHEST POPS (30) OVER WRN/SRN PORTIONS FCST AREA WITH AFOREMENTIONED CONVERGENCE AXIS OVER NRN KY AND POSSIBILITY THAT SOME OF THE ONGOING TSTMS OVER INDIANA WILL MAKE IT INTO FAR WRN FCST AREA THIS EVNG. WILL INDICATE 20 POPS ELSEWHERE FOR ISOLD SHORT-LIVED CONVECTION DVLPG OFF OF MUCAPES INVOF 1000 J/KG. ANY CONVECTION SHOULD BE DONE BY MIDNIGHT WITH LOSS OF DAYTIME HEATING AND NO APPRECIABLE FORCING FOR OVERNIGHT HOURS. LOCALIZED AREAS OF BR/HZ ARE EXPECTED TOWARDS DAYBREAK IN HUMID AIRMASS. TEMPS...ANOTHER HUMID NIGHT IN STORE WITH TEMPS FALLING ONLY INTO U60S TO AROUND 70. TRENDED TOWARDS WARMER MET GUID WITH DEWPTS EXPECTED IN M/U60S OVERNIGHT. RYAN && .SHORT TERM /6 AM WEDNESDAY MORNING THROUGH WEDNESDAY NIGHT/... MODEL GUID IN EXCELLENT AGREEMENT FOR WED/WED NIGHT. REGION REMAINS ON NRN FRINGE OF MID LVL RIDGE CENTERED OVER SE CONUS. AFOREMENTIONED MID LVL DISTURBANCE WILL BECOME ABSORBED BY MORE ZONAL MID LVL FLO AS STRONG S/WV PASSES ACRS CANADA AND NRN GRT LKS. REMNANTS OF DISTURBANCE NOTED BY WEAK MID LVL S/WV EMBEDDED IN ZONAL FLO WED AFTN PASSING THRU NRN IN/OH. THIS COMBINED WITH DVLPG LO LVL CONV AND PLENTY OF LO LVL MOISTURE WITH MUCAPES BTWN 15000-2000 J/KG SHOULD ENABLE BETTER COVERAGE TO TSTM DVLPMNT ACRS WEST CNTRL OH FOR AFTN HOURS. FURTHER SOUTH AND EAST...PROXIMITY TO MID LVL RIDGE WILL KEEP TSTMS MORE ISOLD...PARTICULARLY SOUTH/EAST OF I-71. STRONG COLD FRONT MOVING ACRS WESTERN GRT LKS WED WILL SAG INTO NRN IN/OH WED NIGHT WITH MID LVL HGTS FALLING AS RIDGE BEGINS TO DVLP OVER CNTRL/HIGH PLAINS. LO LVL CONV INCREASES ACRS NRN FCST AREA WED NIGHT AS 30KT 850 LLJ DVLPS AHEAD OF FRNTL BNDRY. THIS COMBINED WITH GOOD MID/UPR LVL FORCING SHOULD ENABLE FOR AN INCREASE IN CONVECTIVE COVERAGE WED NIGHT. HAVE INCREASED TO 50 POPS WED NIGHT FOR AREAS NORTH OF I-70. ONCE AGAIN...LOWEST CHANCES FOR PCPN WILL RESIDE OVER SE FCST AREA...CLOSEST TO RETREATING RIDGE AND FURTHEST AWAY FROM BEST FORCING ASSOCD WITH FRNTL BNDRY. BENEFICIAL HVY RAINFALL IS LOOKING LIKE A GOOD BET WITH PWATS CLIMBING TO BTWN 1.75-2 IN BY LATE WED NIGHT. APPEARS THIS WILL BE ONE OF THE BETTER CHANCES AT A WIDESPREAD RAINFALL EVENT FOR FCST AREA THAT THIS REGION HAS SEEN OVER LAST FEW MONTHS. TEMPS...MET TEMPS LOOK MUCH TOO COOL FOR WED AFTN HIGHS...AND THINK THIS MAY BE DUE TO NAM MODEL OVERDVLPG QPF AND CLOUDS ACRS FCST AREA. TEMPS HAVE ENDED UP MUCH CLOSER TO MAV GUID LAST SVRL DAYS AND EXPECT THAT TO HAPPEN AGAIN ON WED. HAVE GENERALLY GONE A DEG OR TWO BELOW MAV GUID...WITH ALL BUT NW FCST AREA LIKELY TO GET TO 90 OR INTO L90S. CONSIDERING THAT BOTH KCVG AND KCMH HAVE MADE IT TO 92 SO FAR TODAY...MAY END UP VERY CLOSE TO MAV GUID TEMPS DEPENDING ON CLOUDS ANY WDLY SCT CONVECTION THAT DVLPS ALONG I-71 CORRIDOR. LOWS WILL REMAIN NEAR 70 DEG WED NIGHT. RYAN && .LONG TERM /THURSDAY THROUGH TUESDAY/... FOR THURSDAY INTO THURSDAY EVENING...THE NAM AND GFS ARE IN GENERALLY GOOD AGREEMENT WITH A COLD FRONT SAGGING ACROSS THE AREA. MODERATE INSTABILITY BUILDS DURING THE AFTERNOON...AND SHOWERS AND THUNDERSTORMS ARE LIKELY. HIGH TEMPERATURES WILL BE SEASONABLE...HIGHLY DEPENDANT ON CLOUDS/RAINFALL TIMING...WITH A PROMINENT NORTH/SOUTH GRADIENT HIGHLY PLAUSIBLE. THE PCPN ENDS QUICKLY NORTH TO SOUTH ACROSS NORTHERN OHIO AND INDIANA EARLY FRIDAY...ALTHOUGH RECENT TRENDS SHOW THE FRONT STALLING A BIT IN SOUTHERN OHIO AND NORTHERN KY DURING THE DAY ON FRIDAY AS A WAVE DEVELOPS ALONG THE BNDRY. AT THIS POINT...IT APPEARS THAT THE FRONT WILL PUSH SOUTH OF THE FCST AREA FRIDAY NIGHT. SATURDAY THROUGH TUESDAY...MODEL CONSENSUS SHOWS BROAD CANADIAN HIGH PRESSURE BUILDING AND THEN MOVING EAST OF THE REGION. SLIGHT COOLER THAN NORMAL TEMPERATURES WILL STEADILY INCREASE THROUGH THE PERIOD. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... UPR LVL LOW CENTERED OVER CNTRL ILLINOIS WILL CONTINUE TO WEAKEN AS IT DRIFTS NORTH INTO NRN ILLINOIS THIS EVENING. THE LOW WILL EVENTUALLY BECOME ABSORBED IN THE WNW FLOW ALOFT ACRS THE LOWER GREAT LAKES. THE PROXIMITY OF THIS LOW...COMBINED WITH DAYTIME INSTABILITY...WILL TRIGGER MAINLY ISOLATED THUNDERSTORMS THIS AFTN AND EARLY EVENING. WITH LOW COVERAGE EXPECTED...VFR CONDITIONS WILL BE FCST AT THE TAF SITES THROUGH 00Z. FOR TONIGHT...SCATTERED TO OCCASIONALLY BROKEN MID LVL CLOUDS ARE EXPECTED. SOME MVFR CONDITIONS IN MIST MAY FORM AT THE TYPICAL TAF SITES OF KLUK...KILN AND KLCK. OTHERWISE...ISOLATED TO SCATTERED CONVECTION WILL DEVELOP ONCE AGAIN ON WEDNESDAY AS THE SAME AIRMASS REMAINS OVER THE REGION. OUTLOOK...NUMEROUS SHOWERS AND THUNDERSTORMS ARE POSSIBLE THURSDAY AND THURSDAY NIGHT. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. &&
