NWS Wilmington, OH wrote its last area forecast discussion before the first event at May 10, 12:36 PM EST, 1 hour 53 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 136 PM EDT SAT MAY 10 2014 .SYNOPSIS... A WAVE OF LOW PRESSURE TRAVELING ALONG A FRONTAL BOUNDARY WILL PROVIDE NUMEROUS SHOWERS AND THUNDERSTORMS TODAY MAINLY OVER SOUTHERN LOCATIONS. ANOTHER DISTURBANCE WILL BRING A CHANCE FOR MORE SHOWERS AND THUNDERSTORMS ON SUNDAY. DRIER WEATHER IS EXPECTED FOR MONDAY WHEN A WARM FRONT IS FORECAST TO BE POSITIONED OVER THE GREAT LAKES. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... A SLOWLY MOVING COLD FRONT ACROSS NORTHERN OHIO AND INDIANA WILL CONTINUE TO SHIFT EAST THROUGH THE AFTERNOON. SOUTH OF THIS FRONT...SHOWERS WILL CONTINUE THROUGH THE MID MORNING WITH AN OVERALL WEAKENING TREND INTO THE LATE MORNING AS ONE DISTURBANCE PASSES TO OUR SOUTHEAST. REDEVELOPMENT OR AN INCREASE IN COVERAGE OF SHOWERS WITH ISOLATED THUNDERSTORMS IS EXPECTED DURING THE EARLY AFTERNOON AS ANOTHER DISTURBANCE MOVES WEST TO EAST ACROSS OUR AREA. RAMPED UP POPS DURING THE EARLY AFTERNOON TO LIKELY SOUTH OF THE FRONT...MAINLY ALONG AND SOUTH OF INTERSTATE 71. THESE SHOWERS AND THUNDERSTORMS COULD PRODUCE LOCALLY HEAVY RAINFALL WITH PWAT VALUES SAMPLED BY THE ILN 12Z SOUNDING AROUND 1.25 INCHES WITH A THIN/WARM CAPE PROFILE. ANY RADAR ECHOES EXCEEDING 40 DBZ WILL LIKELY PRODUCE HEAVY DOWNPOURS WITH VISIBILITIES UNDER A MILE. BASED ON THE FACT THAT SOME LOCATIONS HAVE RECEIVED AN INCH OF RAINFALL IN THE PAST 24 HOURS WITH ADDITIONAL LOCALIZED AMOUNTS OF 1 TO 2 INCHES OF RAINFALL POSSIBLE INTO THE AFTERNOON...WILL MENTION HEAVY RAIN POTENTIAL IN THE HWO. PRECIPITATION WILL BEGIN TO SHIFT EAST OF OUR AREA ALONG WITH THE DISTURBANCE DURING THE LATE AFTERNOON. LOWERED HIGH TEMPERATURES BY A FEW DEGREES ALONG AND SOUTH OF THE INTERSTATE 71 CORRIDOR DUE TO THE ONGOING PRESENCE OF CLOUD COVER AND SHOWERS...AND A MORE PROLONGED EXPECTATION OF THESE SHOWERS NOW INTO THE AFTERNOON. && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/... FRONTAL ZONE WILL CONTINUE TO MOVE EAST AND WEAKEN TONIGHT. THIS WILL ALLOW SHOWERS AND THUNDERSTORMS TO END EARLY TONIGHT. MODELS INDICATE THAT A WARM FRONT WILL DEVELOP AND LIFT NORTHWARD ACROSS THE AREA ON SUNDAY. THOUGH MODEL QPF IS LESS ROBUST FOR THIS SYSTEM THAN ON PREVIOUS RUNS...HAVE KEPT A CHANCE OF SHOWERS AND THUNDERSTORMS FOR SUNDAY. FOR MONDAY...MODELS SHOW WARM FRONT OVER THE GREAT LAKES. THIS REGIME SHOULD PROVIDE MAINLY DRY WEATHER...THOUGH ISOLATED THUNDERSTORMS MAY POP UP IN NORTHERN LOCATIONS CLOSER TO THE FRONT. TEMPERATURES WILL STAY ABOVE NORMAL. HIGHS AROUND 80 ARE FORECAST FOR SUNDAY...AND LOWER 80S MONDAY. && .LONG TERM /MONDAY THROUGH FRIDAY/... RIDGE OF HIGH PRESSURE IN THE WAKE OF A WARM FRONT WILL BUILD IN WITH INCREASING MOISTURE TO THE OHIO VALLEY THROUGH WEDNESDAY. ON WEDNESDAY...A COLD FRONT WILL BE CROSSING THE REGION EARLY...WITH SIGNIFICANTLY COOLER TEMPERATURES FOUND BEHIND IT ON THIS DAY AND THURSDAY. MODELS WERE LEANING TOWARDS THE SLOWER AND LESS AMPLIFIED ECMWF ENSEMBLE SOLUTION BUT STILL HAD THE COLD FRONT THROUGH WESTERN OHIO BY 12Z WED. THE HIGH TEMPS WED DID NOT AGREE WITH THEIR SFC PROGS AND I COULD NOT COME IN LINE WITH THE 80 DEG AT CMH NOTED FROM ECMWF. TOOK YESTERDAYS FORECAST AND BLENDED WITH THE GFS/ECMWF...LEANING HEAVILY ON PREVIOUS COLDER FORECAST. THURSDAY SHOULD BE THE COLDEST DAY IN THE FORECAST WITH HIGHS IN THE LOW TO MID 60S. EVEN WITH A CONTINUED COLD ADVECTION PATTERN ON FRIDAY...READINGS SHOULD BE AT LEAST A FEW DEGREES WARMER. OVERNIGHT LOWS IN THE 60S MONDAY WILL DROP TO THE 50S TUESDAY AND ROUND OUT THE WEEK IN 40S. THE HIGHEST CHANCE FOR SHOWERS WILL OCCUR WITH THE FROPA TUES AND EARLY WED. I DID NOT INCLUDE THUNDER MONDAY NIGHT THINKING THAT THE WARM SECTOR SHOWERS WOULD BE VERY SPOTTY AND OCCUR UNDERNEATH THE UPPER RIDGE. ONCE THE THUNDER THREAT PASSED ON WEDNESDAY IN THE WAKE OF THE FRONT...SHOWERS WOULD BE POSSIBLE IN THE COLD POOL THURSDAY AND TO A LESSER EXTENT FRIDAY...BOTH DUE TO THE DAYTIME SUN HITTING A COOL AND MOIST COLUMN. && .AVIATION /18Z SATURDAY THROUGH THURSDAY/... A LINE OF SHOWERS AND THUNDERSTORMS WILL SLOWLY SHIFT SOUTHEASTWARD THROUGH THE AFTERNOON. THE BACK EDGE OF THIS ACTIVITY HAS REACHED KDAY AND WILL REACH OUR REMAINING TERMINALS BY AROUND 20Z. UNTIL THAT TIME...MVFR CIGS AND VSBYS WILL BE LIKELY WITH OCCASIONAL IFR VSBYS IN HEAVIER PRECIPITATION. VFR CONDITIONS ARE EXPECTED THIS EVENING THROUGH THE EARLY MORNING. FOG DEVELOPMENT WILL BE POSSIBLE BEFORE SUNRISE WITH MANY AREAS HAVING SEE RAINFALL TODAY...AND CLEARING SKIES TONIGHT. THIS FOG WILL BURN OFF AFTER SUNRISE SUNDAY. ADDITIONAL SHOWERS AND THUNDERSTORMS WILL BE POSSIBLE MIDDAY SUNDAY. HOWEVER...AT THIS TIME IT APPEARS THE COVERAGE WILL BE LOW. OUTLOOK...THUNDERSTORMS POSSIBLE TUESDAY AND TUESDAY NIGHT. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE.
