Area forecast discussion, Jun 16, 4:09 PM EDT, 2 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 409 PM EDT SAT JUN 16 2012 .SYNOPSIS... AN UPPER LEVEL DISTURBANCE WILL ENTER THE OHIO VALLEY FROM THE MIDWEST TONIGHT...BREAKING DOWN AN ESTABLISHED UPPER LEVEL RIDGE. THE ATMOSPHERE WILL QUICKLY REESTABLISH THIS RIDGE LATER ON MONDAY AND HIGH PRESSURE WILL PREVAIL THROUGH AT LEAST MID WEEK. && .NEAR TERM /UNTIL 6 AM SUNDAY MORNING/... GFS IS THE ONLY MODEL EVEN REMOTELY HANDLING THE EARLIER PRECIP OVER KY THAT HAS BLOSSOMED IN MUCH OF THE REST OF OHIO VALLEY. ATMOSPHERE AHEAD OF THE MID LEVEL S/W APPROACHING FROM THE MIDWEST PRIMES ITSELF WITH A LARGE SWATH OF UVV NOTED AT H7 OVER WRN OH AND SRN IN AT 6Z. H5 RIDGE IS STILL BEING BEATEN DOWN AT THIS TIME OVER THE AREA BUT HAS ENOUGH OF A LID OVER THE REGION THAT THE SHOWERS THAT DO POP IN IT TONIGHT HAVE A MINIMAL CHANCE FOR BECOMING SEVERE. && .SHORT TERM /6 AM SUNDAY MORNING THROUGH MONDAY/... BY DAYBREAK...THERE SHOULD BE ENOUGH CLOUD COVER OVER CWA AND OHIO VALLEY TO REMOVE THE ADDED KICK OF DIURNAL HEATING. WHILE STORMS WILL BE PRESENT FROM THE MORNING INTO THE AFTERNOON...THERE MAY BE A MARKED LACK OF ORGANIZED CONVECTION. THE H5 RIDGE IS SUFFICIENTLY BEATEN DOWN BY THE EVENING AND THE SHOWERS WILL DIMINISH IN COVERAGE AND STRENGTH THROUGH THE OVERNIGHT HOURS. SURFACE FLOW NEVER SWITCHES FROM SOUTHWEST AND THERE MAY BE ENOUGH CONVERGENCE IN THE LOWER LEVELS TO KEEP A SHOWER THREAT GOING THROUGH DAYBREAK. THE CONVERGENT AREA WILL LIFT NORTHEAST ON MONDAY IN THE MEAN FLOW AND A LINGERING SHOWER EARLY IN THE DAY CANNOT BE RULED OUT...PRIMARILY IN NERN CWA. WHILE LIKELY POPS ARE EXPRESSED IN THE FORECAST AT 18Z SUNDAY...I WAS NOT CONVINCED OF THAT AT THAT HOUR...BUT I HAVE LITTLE DOUBT THAT AN AREA OF SHOWERS WILL MOVE FROM NW TO SE OVER CWA DURING THE DAY AND I AM KEEPING THE GRID UNCHANGED. TEMPERATURES WERE NOT CHANGED MUCH FROM PREVIOUS FORECAST. && .LONG TERM /MONDAY NIGHT THROUGH SATURDAY/... EXTENDED PERIOD BEGINS WITH REGION UNDER H5 RIDGE AND ON WRN EDGE OF SFC HIGH PRESSURE. THIS PATTERN HOLDS FOR THE FIRST FEW COUPLE OF DAYS OF THE FORECAST. THE GFS THEN TRIES TO BRING SOME ENERGY UP FROM THE S AROUND THE CENTER OF RIDGE AND PRODUCES SOME QPF WED NIGHT INTO THU. NEITHER ECMWF AND CMC SHOWS THIS...SO WILL DISCOUNT THE GFS PCPN. A CDFNT THEN PUSHES THROUGH THE GREAT LAKES AND ACROSS THE FA THU NGT INTO FRIDAY. THE 12Z ECMWF HAS BECOME MORE MUTED WITH THIS THAN THE GFS OR CMC. WILL THEN TOWARDS THE MAJORITY FORECAST...AND WILL BRING CHC POPS ACROSS THE FA WITH THE FRONT. HIGH PRESSURE BUILDS IN FROM THE NW FOR FRI NGT INTO SATURDAY. RAN A BLEND OF PREVIOUS AND HPC TEMPERATURES FOR TEMPERATURES THROUGH THE FORECAST. && .AVIATION /20Z SATURDAY THROUGH THURSDAY/... QUITE A BIT OF CU HAS DEVELOPED ACROSS THE WESTERN TAF SITES. LESS CU HAS DEVELOPED AROUND THE KCMH AND KLCK AREA THIS AFTERNOON. ISOLATED TO SCATTERED SHOWER AND THUNDERSTORM ACTIVITY HAS DEVELOPED ACROSS EASTERN INDIANA...NORTHERN KENTUCKY...AND WESTERN OHIO. EXPECT THIS ACTIVITY TO REMAIN ACROSS THE AREA THROUGH THE AFTERNOON AND EARLY EVENING HOURS. AT THIS POINT HAVE LIMITED PRECIPITATION MENTION TO MAINLY VCSH HOWEVER ADDED VCTS MENTION TO KCVG FOR A FEW HOURS THIS AFTERNOON. EXPECT THUNDERSTORM ACTIVITY TO DECREASE FOR A FEW HOURS DURING THE EVENING HOURS. ADDITIONAL SHOWER AND THUNDERSTORM ACTIVITY WILL BE POSSIBLE DURING THE OVERNIGHT HOURS AND INTO THE DAY ON SUNDAY AS A DISTURBANCE APPROACHES THE AREA. ALTHOUGH ISOLATED THUNDER WILL BE POSSIBLE AT ANY POINT DURING THIS TIME...LIMITED MENTION OF THUNDER IN THE TAFS TO THE TIME FRAME THAT WILL HAVE THE POSSIBILITY OF THE MOST THUNDER ACTIVITY. AT THIS POINT IN TIME IT APPEARS THAT THIS WILL BE DURING THE LATE MORNING AND INTO THE AFTERNOON HOURS ON SUNDAY. DUE TO THIS HAVE ADDED A VCTS AND CB MENTION IN DURING THIS TIME. OUTLOOK...THUNDERSTORMS POSSIBLE SUNDAY INTO SUNDAY NIGHT. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. && SYNOPSIS...FRANKS NEAR TERM...FRANKS SHORT TERM...FRANKS LONG TERM...SITES AVIATION...NOVAK
