The episode as NWS LMK wrote it up.
A weak cool front dropped into southern Indiana and northern Kentucky during the day on June 3. With afternoon heating the atmosphere destabilized and scattered thunderstorms were able to develop. A few of these storms became strong enough to produce isolated damaging wind gusts.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Louisville, KY wrote its last area forecast discussion before the first event at Jun 3, 12:48 PM CST, 4 hours 1 minute earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LOUISVILLE KY 248 PM EDT THU JUN 3 2010 .SHORT TERM (TONIGHT AND FRIDAY)... A SLIGHTLY DRIER LOWER ATMOSPHERE COMBINED WITH A LACK OF A BOUNDARY HAD PREVENTED THUNDERSTORM DEVELOPMENT ACROSS THE FORECAST AREA AT 18Z. HOWEVER IT STILL LOOKS AS IF A LINE OF THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE FROM EXTREME NORTHEAST ARKANSAS INTO CENTRAL KENTUCKY LATE THIS AFTERNOON OR EVENING. THIS IS THE AREA WHERE THE SPC HAS INDICATED THE POTENTIAL FOR STRONG THUNDERSTORMS TO OCCUR. OTHER STORMS MAY DEVELOP OVER CENTRAL ILLINOIS AND INDIANA BUT I FEEL MOST OF THESE STORMS WOULD REMAIN NORTH OF THE REGION. SO FOR LATE THIS AFTERNOON AND EVENING WE WILL HOLD POPS IN THE CHANCE CATEGORY. IF STORMS DO DEVELOP SOME OF THE STRONG STORMS WILL BE CAPABLE OF PRODUCING HEAVY RAIN AND GUSTY WINDS. OVERALL THE SYNOPTIC PATTERN WILL NOT CHANGE MUCH DURING THIS FORECAST PERIOD. A STRONG UPPER ZONAL JET WILL BE NOTED ACROSS THE NORTHERN TIER STATES WITH A FEW RIPPLES IN THE FLOW WHICH WILL DEVELOP SURFACE LOWS AND MOVE THEM ACROSS THE GREAT LAKES REGION. THE LOWER OHIO VALLEY WILL REMAIN IN A MOIST UNSTABLE AIR MASS. IT DOES LOOK AS IF FRIDAY WILL HAVE A LESS CHANCE OF STORMS WITH A COUPLE OF LOWS MOVING ACROSS THE GULF COAST STATES. TEMPERATURES TONIGHT AND FRIDAY WILL BE SIMILAR TO THE LAST FEW DAYS WITH LOWS IN THE UPPER 60S AND LOW 70S AND HIGHS IN THE 80S AND LOW 90S. .LONG TERM (FRIDAY NIGHT - THURSDAY)... UPPER AIR PATTERN FOR THE EARLY PORTION OF THE WEEKEND WILL FEATURE A VERY FAST ZONAL FLOW ACROSS THE NORTHERN TIER OF STATES. EARLY SATURDAY...THE NOSE OF A STRONG JET WILL BE APPROACHING THE WESTERN GREAT LAKES. BY EARLY MONDAY THIS PATTERN WILL AMPLIFY SLIGHTLY AS STRONG 500MB RIDGING DEVELOPS ACROSS THE DESERT SOUTHWEST. THE MOST RECENT GFS HAS COME INTO BETTER AGREEMENT WITH THE ECMWF AND THE GFS ENSEMBLES WITH DE-EMPHASIZING THE AMPLIFICATION OF THE TROUGH OVER THE GREAT LAKES LATE SUNDAY. BY EARLY FRIDAY...A VERY QUICK MOVING FLAT SHORTWAVE WILL MOVE ACROSS THE WESTERN GREAT LAKES. WEAK SURFACE LOW PRESSURE WILL SCOOT FROM WISCONSIN THROUGH LAKE HURON BY EARLY SATURDAY. WITH ALL OF THE DYNAMICS OF THIS SYSTEM WELL NORTH...EXPECT A WARM MOSTLY SUNNY DAY WITH ISOLATED AFTERNOON AND EVENING THUNDERSTORMS. AS THE 850MB LOW LEVEL JET INCREASES LATE SATURDAY ACROSS THE MIDWEST...GUIDANCE HAS COME INTO AGREEMENT WITH THE DEVELOPMENT OF A NOCTURNAL CONVECTIVE SYSTEM THAT WILL LIKELY MOVE OVER NORTHERN ILLINOIS AND INDIANA LATE SATURDAY AND EARLY SUNDAY. THIS TRACK WILL LIKELY STAY NORTH OF OUR FORECAST AREA...ALTHOUGH IT IS POSSIBLE FOR CONVECTION TO DEVELOP LATE SATURDAY OR EARLY SUNDAY ACROSS OUR NORTHERN COUNTIES SHOULD AN OUTFLOW BOUNDARY TRAVEL FAR ENOUGH SOUTH. THROUGHOUT THIS ENTIRE WEEKEND...THE STORM TRACK WILL REMAIN NORTH. HOWEVER...THE ENTIRE LOWER OHIO VALLEY WILL REMAIN WITHIN A WARM AND HUMID AIRMASS. CANNOT RULE OUT ISOLATED AFTERNOON AND EVENING THUNDERSTORM DEVELOPMENT SATURDAY DESPITE A LACK OF ANY FORCING OR FRONTS. BOTH THE NAM AND THE GFS ENSEMBLES BRING A COLD FRONT AND A SWITCH TO LIGHT NORTHERLY WINDS DURING THE AFTERNOON SUNDAY. THIS FRONT...WHILE NOT NOTICEABLY COOLING TEMPERATURES...WILL BRING IN DRIER AIR TO AT LEAST THE TENNESSEE BORDER LATE SUNDAY. EXPECT MOSTLY CLEAR SKIES FROM LATE SUNDAY THROUGH EARLY TUESDAY WITH SLIGHTLY LOWER DEWPOINTS. A FAST NORTHWESTERLY FLOW WILL BECOME ESTABLISHED TUESDAY THROUGH THURSDAY WITH THE JET ALIGNED FROM MONTANA THROUGH NORTHERN OHIO. THIS PATTERN CAN BRING RECURRING BOUTS OF CONVECTION ALONG ANY BAROCLINIC ZONE THAT DEVELOPS SOUTH OF THE JET. WILL INTRODUCE POPS FOR POTENTIAL CONVECTION TUESDAY AFTERNOON THROUGH EARLY THURSDAY AS SEVERAL FAST MOVING DISTURBANCES MOVE ACROSS THE NORTHERN OHIO VALLEY. && .AVIATION (18Z TAF ISSUANCE)... SCATTERED THUNDERSTORMS WILL AGAIN BE POSSIBLE IN THE UNSTABLE AIRMASS ACROSS THE LOWER OHIO VALLEY THIS AFTERNOON AND EVENING. BOUNDARIES ARE NOT AS OBVIOUS TODAY AS YESTERDAY SO WE DO NOT EXPECT ORGANIZED LINES OR AREAS. BECAUSE OF THE UNCERTAINTY WE WILL ONLY MENTION VCTS IN THE TAFS AFTER 20Z. OTHERWISE LOOK FOR VFR CONDITIONS EXCEPT FOR SOME FOG AROUND DAYBREAK FRIDAY. A WEAK SOUTHWEST LOW LEVEL FLOW WILL BE NOTED. && .LMK WATCHES/WARNINGS/ADVISORIES... KY...NONE.
