NWS Wilmington, OH wrote its last area forecast discussion before the first event at May 10, 1:00 PM EST, 1 hour 5 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE WILMINGTON OH 200 PM EDT TUE MAY 10 2016 .SYNOPSIS... CHANCES OF SHOWERS AND THUNDERSTORMS WILL REMAIN IN THE FORECAST TODAY AND TONIGHT...AS A WARM FRONT SLOWLY MOVES NORTH THROUGH THE AREA. AFTER A BRIEF PERIOD OF DRY CONDITIONS ON WEDNESDAY...A COLD FRONT WILL BRING ANOTHER CHANCE OF SHOWERS AND STORMS ON THURSDAY...WITH ANOTHER COLD FRONT FOLLOWING BEHIND ON FRIDAY NIGHT. BEHIND THESE FRONTS...COOLER AIR IS EXPECTED FOR THE WEEKEND. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... INITIAL BAND OF SHOWERS CONTINUES TO SLOWLY PIVOT NORTHEAST ACROSS THE FORECAST AREA. SECOND AREA OF CONVECTION AHEAD OF A WELL DEFINED MID LEVEL CIRCULATION IS ALREADY MOVING INTO SOUTH CENTRAL INDIANA. BASED ON OBSERVED TRENDS...HAVE NARROWED THE GAP BETWEEN INITIAL PRECIPITATION AND SECOND ROUND IMPACTING THE REGION. THIS WILL ALSO PLAY A ROLE IN INSTABILITY...WITH A NARROWER WINDOW FOR DESTABILIZATION. BASED ON RECENT HIGH RESOLUTION RUNS...IT IS STARTING TO LOOK LIKE MULTIPLE CLUSTERS OF SHOWERS AND THUNDERSTORMS MOVING ACROSS THE AREA INSTEAD OF JUST ONE CLUSTER WITH THE SOUTHERN COUNTIES SEEING THE MOST AND STRONGEST ACTIVITY. IT SEEMS THAT THE SEVERE WEATHER THREAT IS A BIT LOWER THAN EARLIER THOUGHT WHILE THE THREAT FOR FLASH FLOODING IS A LITTLE HIGHER. GREATEST POTENTIAL FOR HAZARDOUS WEATHER WILL CONTINUE TO BE IN THE SOUTHWEST COUNTIES WITH DAMAGING STRAIGHT LINE WINDS AND FLASH FLOODING BEING THE PRIMARY THREATS. && .SHORT TERM /6 PM THIS EVENING THROUGH FRIDAY/... CONTINUED SHOWER AND THUNDERSTORM DEVELOPMENT IS EXPECTED AT TIMES GOING INTO THE OVERNIGHT HOURS...AS THE SHORTWAVE VERY SLOWLY MOVES ENE THROUGH THE OHIO VALLEY AND INTO THE SOUTHERN GREAT LAKES. UNTIL THE AXIS OF THIS WAVE HAS PASSED...PRECIPITATION WILL REMAIN POSSIBLE...THOUGH THE THREAT FOR ANY STRONG STORMS WILL LIKELY DIMINISH AFTER THIS EVENING. A NARROW RIDGE IS EXPECTED TO MOVE INTO THE AREA ON WEDNESDAY AND INTO WEDNESDAY NIGHT...WHICH 00Z MODELS HAVE COME INTO A LITTLE BETTER AGREEMENT ON...ALLOWING FOR A PERIOD OF LOWERED POPS. THIS WILL CHANGE AGAIN GOING INTO THURSDAY MORNING...IN ADVANCE OF A COLD FRONT...AND WITH THE OVERALL PATTERN SHIFTING AGAIN FROM RIDGING TO TROUGHING (AND HEIGHT FALLS OVER THE ILN CWA). FRONTAL TIMING ON THURSDAY APPEARS SLIGHTLY SLOWER THAN PREVIOUSLY ANTICIPATED...BUT WITH NO SIGNIFICANT CHANGES TO THE OVERALL SCENARIO. STRONGER WARM ADVECTION THIS TIME AROUND SHOULD ALLOW FOR TEMPERATURES TO INCREASE MORE SIGNIFICANTLY IN ADVANCE OF THE FRONT. THE MOIST PATTERN AND SLOW MOVEMENT OF THE FRONT ARE NOT HARBINGERS FOR SIGNIFICANT STRONG STORMS...BUT THERE WILL PROBABLY BE SOME LEVEL OF SEVERE THREAT TO CONTEND WITH ON THURSDAY. MUCH DRIER AIR IS FORECAST TO MOVE IN BEHIND THE FRONT...ALONG WITH A COOL DOWN OF AROUND 10 DEGREES FROM THURSDAY TO FRIDAY. && .LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... WE WILL GET INTO A BRIEF PERIOD OF DRYING BEHIND THE FRONT ON FRIDAY AS TEMPERATURES RETURN TO MORE SEASONABLE READINGS IN THE UPPER 60S TO LOWER 70S. A NORTHWEST FLOW PATTERN ALOFT WILL THEN BE IN PLACE ACROSS THE REGION FOR THE WEEKEND...GRADUALLY TRANSITIONING TO MORE OF A ZONAL FLOW PATTERN THROUGH EARLY NEXT WEEK. A SERIES OF EMBEDDED WEAK DISTURBANCES WILL DROP DOWN ACROSS THE AREA FRIDAY NIGHT INTO SATURDAY...AND THEN AGAIN SUNDAY NIGHT INTO MONDAY...BRINGING ADDITIONAL CHANCES FOR SHOWERS. BELOW NORMAL TEMPERATURE READINGS ARE EXPECTED THROUGH THE END OF THE LONG TERM PERIOD...WITH HIGHS GENERALLY IN THE 60S. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... A FRONTAL BOUNDARY WILL CONTINUE TO LIFT E/NE THROUGH THE FCST AREA THROUGH THE AFT AND EVE. SHOWERS WILL MOVE AHEAD OF THE BOUNDARY THROUGH ALL TAF SITES EXCEPT KCVG AND KLUK THROUGH 00Z. CONVECTION ALLOWING MODELS CONTINUE TO INDICATE SUBSEQUENT ROUNDS OF SHOWERS/THUNDERSTORMS MOVING INTO AREA THIS AFT AND EVE. MAIN CONCERN WITH THIS ACTIVITY WILL BE BRIEF REDUCTIONS IN VSBYS AND LOWERING OF CIGS IN HEAVIER SHRA/TSRA. INSTABILITY LOOKS TO BE MORE LIMITED FOR KDAY...KCMH...AND KLCK... ESPECIALLY CONSIDERING AFTERNOON CLOUD COVER AND PRECEDING PRECIPITATION. DID INCLUDE THUNDER FOR KCVG...AND KLUK... AS ENVIRONMENT WILL LIKELY DESTABILIZE ENOUGH FOR SECONDARY ACTIVITY. WINDS WILL GENERALLY BE SOUTHERLY THROUGH THE EVENING HOURS FOR ALL TERMINALS. AFTER 06Z... INSTABILITY WILL WANE AND FORCING WILL WEAKEN... THEREFORE EXPECT THAT SHRA/TS ACTIVITY WILL BECOME MORE SCATTERED AS IT SHIFTS SOUTH AND EAST OF ALL TERMINALS... ALLOWING FOR MVFR CIGS TO SETTLE INTO THE AREA. IFR CIGS ARE POSSIBLE TONIGHT... BUT CONFIDENCE IS NOT SUFFICIENT TO INCLUDE RIGHT NOW. SUFFICIENT LOW LEVEL MOISTURE WILL ALLOW FOR MVFR/IFR CIGS AND MIST BETWEEN 06Z AND 12Z WEDNESDAY ACROSS ALL TERMINALS. EXPECT THAT WINDS WILL BE LIGHT SOUTHWESTERLY THROUGH OVERNIGHT PERIOD. OUTLOOK...MVFR/IFR CEILINGS AND VISIBILITIES POSSIBLE WEDNESDAY MORNING. THUNDERSTORMS POSSIBLE THURSDAY INTO THURSDAY NIGHT. MVFR CIGS AND VSBYS WILL AGAIN BE POSSIBLE SATURDAY. && .ILN WATCHES/WARNINGS/ADVISORIES... OH...NONE. KY...NONE. IN...NONE. && SYNOPSIS...HATZOS NEAR TERM...
