NWS Wilmington, OH wrote its last area forecast discussion before the first event at Oct 6, 3:15 PM EST, 2 hours 27 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 415 PM EDT MON OCT 6 2014 .SYNOPSIS... A BROAD UPPER LEVEL TROUGH WILL REMAIN IN PLACE ACROSS THE EASTERN UNITED STATES THROUGH MID WEEK. A SURFACE LOW MOVING THROUGH THE TROUGH WILL RESULT IN A CHANCE OF SHOWERS AND THUNDERSTORMS TUESDAY. AFTER A DRY WEDNESDAY...MORE SHOWERS AND THUNDERSTORMS WILL RETURN TO THE REGION THROUGH THE END OF THE WEEK AS A BOUNDARY SETS UP ALONG THE OHIO RIVER. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... UPSTREAM CONVECTION RUNNING FROM SOUTHWEST MICHIGAN...THROUGH EASTERN INDIANA AND THEN SOUTHWEST TO SOUTHERN ILLINOIS IS NOT HANDLED WELL BY THE MODELS. BELIEVE THAT THE 17Z HRR SOLUTION MAY PROVIDE THE BEST EVOLUTION TO THE STORMS TO THE WEST OVER THE NEXT FEW HOURS. STORMS SHOULD MOVE EAST THIS EVENING AND OUT OF AREA OF CONCERN...WITH ANOTHER BATCH OF STORMS KNOCKING ON SOUTHWEST FCST AREA BY DAYBREAK TUESDAY. OVERNIGHT LOWS WILL BOTTOM OUT IN THE UPPER 40S TO AROUND 50 UNDER A GENERALLY CLOUDY SKY. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/... A SURFACE CIRCULATION UNDERNEATH THE MEAN UPPER TROUGH WILL CROSS FORM ILLINOIS AT DAYBREAK TUESDAY THROUGH INDIANA...TO EASTERN OHIO BY EVENING. SHOWERS AND SOME EMBEDDED THUNDERSTORMS WILL ACCOMPANY THIS CIRCULATION AND SPREAD QUICKLY NORTHEAST DURING DAYLIGHT HOURS. WAS NOT CONVINCED THAT THE THUNDER CHANCES WOULD BE LIMITED TO JUST SOUTHERN CWA...SO I TOOK A BROAD APPROACH AND HAD A CHANCE OF TSTORMS INCREASE DURING DAYLIGHT HOURS WHERE POPS WERE HIGHER THAN 25%. FORCING FROM THIS CIRCULATION WILL HAVE A DISTINCT BACK EDGE THAT SHOULD HAVE SHOWERS OVER BY EVENING AND A GENERAL CLEARING ON NORTHWEST WINDS TUESDAY NIGHT. A BRIEF RESPITE IN ACTIVE WEATHER IS EXPECTED WEDNESDAY AS SKIES CLEAR SOMEWHAT IN NORTHWEST FLOW ALOFT AND HIGH PRESSURE BUILDING AT THE SURFACE DURING THE DAY WEDNESDAY. THE SURFACE HIGH WILL SLIDE SOUTH OF THE OHIO VALLEY OVERNIGHT WITH DRY AND COOL CONDITIONS EXPECTED. HIGHS THROUGH THE PERIOD WILL BE IN THE 60S WITH LOWS IN THE 40S. && .LONG TERM /THURSDAY THROUGH MONDAY/... EXTENDED MODELS START OFF IN GOOD AGREEMENT...BUT THEN DIVERGE BY THE WEEKEND. MOISTURE FROM EASTERN PACIFIC TROPICAL STORM SIMON HAS REACHED THE MID MISSISSIPPI VALLEY BY THE BEGINNING OF THE PERIOD. THE FAST... NEAR ZONAL FLOW WILL ALLOW PCPN TO QUICKLY SPREAD INTO THE REGION ON THURSDAY. AT THE SAME TIME FRAME ON THURSDAY...A WARM FRONT DEVELOPS IN THE VICINITY OF THE OHIO RIVER. ENERGY IN THE H5 FLOW CAUSES A SFC WAVE ON THE FRONT PUSHING A GOOD AREA OF RAIN ACROSS THE REGION THURSDAY AND THURSDAY NIGHT. THE GFS REMAINS THE STRONGEST WITH THE SFC WAVE AND QPF. THE WAVE PUSHES EAST ON FRIDAY. LEANED TOWARDS THE QUICKER EXITING ECMWF MODEL WHICH WAS CLOSER TO YESTERDAYS GFS. THE GFS SHUNTS THE FRONT FARTHER IN KENTUCKY THAN THE ECMWF OR CMC FRIDAY NIGHT. THIS CAUSES A SLOWER RETURN IN THE PCPN OVER THE WEEKEND. ENERGY DIGGING OUT OF THE SRN ROCKIES PUSHES THE MOISTURE BACK ACROSS REGION SUNDAY AND DEVELOPS CDFNT FRONT WHICH PUSHES ACROSS THE REGION ON MONDAY. AS MENTIONED ABOVE THE GFS IS SLOWER WITH THIS RETURN MOISTURE AND FNT...SO HAVE GONE CLOSER TO THE ECMWF TIMING. AS FOR TEMPERATURES. SLIGHTLY BELOW NORMAL HIGHS...IN THE 60S... THURSDAY AND FRIDAY. EVEN COOLER AIR WORKS IN ON SATURDAY WITH HIGHS IN THE UPPER 50S TO LOWER 60S. WITH THE SOUTHERLY RETURN FLOW FOR SUNDAY AND MONDAY TEMPERATURES WILL WARM BACK UP A FEW DEGREES. && .AVIATION /20Z MONDAY THROUGH SATURDAY/... WINDS WILL PICK UP FOR THE REST OF THE AFTERNOON AND EARLY EVENING HOURS WITH WIND GUSTS AROUND 20 TO 25 KNOTS AT TIMES POSSIBLE. AN AREA OF SHOWERS IS EXPECTED TO MOVE OUT OF THE TAF SITES BY MID AFTERNOON. A FEW SHOWERS WILL STILL BE POSSIBLE FOR THE REST OF THE AFTERNOON. SOME ADDITIONAL SHOWERS ARE BEGINNING TO DEVELOP ACROSS EASTERN ILLINOIS AND WESTERN INDIANA. EXPECT ADDITIONAL DEVELOPMENT IN THAT AREA THIS AFTERNOON AND FOR SOME ISOLATED TO SCATTERED SHOWERS AND STORMS TO MOVE INTO THE TAF SITES THIS EVENING. EXPECT PRECIPITATION TO TAPER OFF TONIGHT AND SKIES WILL BEGIN TO CLEAR OUT. WITH THE PRECIPITATION FROM TODAY AND WITH CLEARING SKIES SOME FOG WILL BE POSSIBLE OVERNIGHT. AT THIS POINT LIMITED MVFR FOG MENTION TO KLUK AND KILN HOWEVER CANNOT RULE OUT FOG AT ANY AREA TAF SITE OVERNIGHT. MID CLOUDS WILL BEGIN TO WORK INTO THE AREA BY MORNING. ANOTHER SYSTEM WILL MOVE INTO THE REGION BY THE END OF THE TAF PERIOD BRINGING ADDITIONAL CHANCES FOR SHOWERS AND THUNDERSTORMS. IN ADDITION SOME MVFR CIGS AND VSBYS WILL ALSO BE POSSIBLE. WINDS WILL PICK UP AGAIN DURING THE DAY ON TUESDAY WITH WIND GUSTS AROUND 20 TO 25 KNOTS EXPECTED. .OUTLOOK...CHANCE OF THUNDERSTORMS ON TUESDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE.
