ARWhat forecasters said that day
The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jackson, KY wrote its last area forecast discussion before this severe thunderstorm warning went out at May 11, 3:50 PM EDT, 8 minutes earlier.
Area forecast discussion, May 11, 3:50 PM EDT, 8 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 350 PM EDT MON MAY 11 2015 .SHORT TERM...(THIS EVENING THROUGH TUESDAY NIGHT) ISSUED AT 350 PM EDT MON MAY 11 2015 A FEW STRONG TO SEVERE STORMS HAVE DEVELOPED ACROSS THE REGION THIS AFTERNOON. THIS PROMPTED A SEVERE THUNDERSTORM WATCH FOR PORTIONS OF THE CWA WITH MAIN THREAT BEING DAMAGING WINDS AND HAIL. THESE STORMS HAVE FIRED UP IN A MODERATELY UNSTABLE ENVIRONMENT WITH SBCAPE AOA 1000 J/KG...SOME DEWPOINTS IN THE LOW TO MID 60S...AND LOW LEVEL LAPSE RATES AROUND 8 C/KM. ALSO SOME EXTRA HELP WITH LIFT FROM WEAK UPPER LEVEL WAVES MOVING THROUGH THE FLOW. THESE SHOWERS AND THUNDERSTORMS WILL CONTINUE TO SUBSIDE TONIGHT...AS BOUNDARY LAYER HEATING BEGINS TO DROP OFF. OVERNIGHT WE COULD SEE POTENTIAL FOR SPRINKLES AS THE FRONT FINALLY SWEEPS ACROSS THE REGION...HOWEVER LEFT THIS OUT OF THE GRIDS AT THIS POINT WITH LOWER CONFIDENCE ON LEFT OVER MOISTURE. MOVING INTO YOUR TUESDAY HIGH PRESSURE WILL BUILD ACROSS THE OHIO VALLEY. THIS WILL USHER IN COOLER AND CLOSER TO NORMAL TEMPS FOR YOU TUESDAY WITH HIGHS GENERALLY IN THE LOW TO MID 70S. THIS HIGH WILL ALSO USHER IN DRYER AIR WITH CLEARING SKIES FROM WEST TO EAST THROUGH THE DAY ON TUESDAY. TUESDAY NIGHT WILL BE COOLER WITH CLEAR SKIES AND LOWS GENERALLY IN THE UPPER 40 TO NEAR 50. .LONG TERM...(WEDNESDAY THROUGH MONDAY) ISSUED AT 350 PM EDT MON MAY 11 2015 LONG TERM TO FOLLOW SHORTLY... && .AVIATION...(FOR THE 18Z TAFS THROUGH 18Z TUESDAY AFTERNOON) ISSUED AT 133 PM EDT MON MAY 11 2015 THIS AFTERNOON WE HAVE SEEN CONVECTION FIRE UP ACROSS PORTIONS OF EASTERN KY. THESE ISOLATED TO SCATTER STORMS WILL BE THE BIGGEST CONCERN FOR THE NEXT FEW HOURS. IT DOES LOOK LIKE THERE COULD BE TWO ROUND...ONE ONGOING CONVECTION MORE DIURNALLY DRIVEN UNDER MODERATELY UNSTABLE ENVIRONMENT...TWO THE COLD FRONT AND ANY OUTFLOWS AHEAD OF THE FRONT. THE SECOND LINE IS IN QUESTION GIVEN THAT STORMS HAVE ALREADY FIRED AND COULD TAP OUT THE CURRENT UNSTABLE ENVIRONMENT. THE BIGGEST THREAT FROM THIS AVIATION WISE LOOKS TO BE THE POTENTIAL FOR GUSTY WINDS AND REDUCED VIS. OTHERWISE OVERNIGHT SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DIE OFF WITH DAYTIME HEATING AND FRONT SWEEPING ACROSS THE REGION. THE OTHER ISSUE TONIGHT WILL BE POTENTIAL FOR FOG AND/OR LOW STRATUS DECK. RIGHT NOW PLAN TO KEEP LOW STRATUS DECK WITH POTENTIAL FOR AT LEAST MVFR CEILINGS OVERNIGHT INTO EARLY TUESDAY. HIGH PRESSURE WILL RETURN TOMORROW WITH CLEARING SKIES. && .JKL WATCHES/WARNINGS/ADVISORIES... NONE. && SHORT TERM...DJ LONG TERM...RAY AVIATION...DJ
