What happened

The episode as NWS PAH wrote it up.

A cold front trailed south-southwestward from a surface low pressure center over west central Illinois through southeast Missouri. This cold front provided the low level lift for short lines of thunderstorms to develop during the late afternoon. Some breaks in the clouds allowed sunshine to destabilize the atmosphere, but mixed layer capes remained at or below 1000 j/kg due to modest lapse rates and low-level moisture. Surface dew points around 60 degrees pooled along the front. Wind profiles were unidirectional and generally parallel to the front. As a result, the storms were mainly organized into short linear structures with some bowing segments that produced damaging wind.

What forecasters said that day

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 Paducah, KY wrote its last area forecast discussion before the first event at Apr 7, 4:05 PM EST, 1 hour 55 minutes earlier.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
405 PM CDT WED APR 7 2010

.DISCUSSION...
DELAYED AND ABBREVIATED DISCUSSION DUE TO ONGOING SEVERE WEATHER
IN THE WFO PAH FORECAST AREA.

MAIN CHALLENGE IN THE SHORT TERM WILL BE THE TIMING OF THE
TRANSITION OF THE CURRENT MESOSCALE CONVECTIVE SYSTEM /MCS/ FROM
DISCRETE/LINE SEGMENT SEVERE STORMS TO A MORE BROAD-BRUSHED HEAVY
RAIN EVENT THROUGH THE EVENING AND OVERNIGHT HOURS. THE 12KM NAM
AND SREF GUIDANCE APPEAR TO HAVE A DECENT HANDLE ON THE EASTWARD
MOVEMENT OF THE MCS AND WERE FOLLOWED IN THE SHORT TERM.

ANY REMAINING SHOWER ACTIVITY SHOULD EXIT THE WFO PAH CWA BY 15Z
/10 AM CDT/ THURSDAY...WITH SIGNIFICANT COLD/DRY AIR ADVECTION IN
PLACE BEYOND THAT TIME. FOR LATE THURSDAY NIGHT...ADDED AN
OCCURRENCE OF PATCHY FROST TO NORTHWEST KENTUCKY AND SOUTHWEST
INDIANA...AS SUFFICIENT LOW LEVEL MOISTURE WILL BE IN PLACE TO
SUPPORT SOME SURFACE CRYSTALLIZATION.

IN THE LONGER TERM...UTILIZED A BLEND OF ECMWF AND EXTENDED WRF
GUIDANCE TO IMPLY A PROLONGED PERIOD OF DRIER WEATHER. AT THIS
TIME...WITH THE RIDGE DOMINATING THE AREA...DIURNAL TEMPERATURE
RANGES BETWEEN 20 AND 27 DEGREES WILL CAN BE EXPECTED...AS LIGHT
SOUTHEAST AND SOUTH WINDS DO NOT ADVECT IN SUFFICIENT LOW LEVEL
MOISTURE FROM THE SOUTHEAST UNITED STATES.

&&

.AVIATION...
MAIN CONSIDERATION WITH THE 18Z WEDNESDAY ROUTINE TAF ISSUANCE AND
AMENDMENTS WILL BE ONGOING CONVECTION OVER EACH OF THE TAF SITES
THROUGH 03Z THURSDAY /10 PM CDT WEDNESDAY/. MOST OF THE MVFR/IFR
CEILING AND VISIBILITY RESTRICTIONS WILL LIKELY BE LIMITED TO AN
HOUR OR LESS OVER KCGI AND POSSIBLY KPAH BETWEEN 21Z WEDNESDAY AND
00Z THURSDAY. THE FRONTAL BOUNDARY IS EXPECTED TO SLOW SOMEWHAT
AFTER THAT TIME...LENDING TO A MORE PROLONGED PERIOD OF LOWER
CEILINGS AT KEVV/KOWB THIS EVENING. ONCE THE CONVECTIVE LINE OF
STORMS MOVE EAST OF THE WFO PAH TAF SITES THIS EVENING...SCATTERED
TO BROKEN CEILINGS BETWEEN 2-3KFT AGL WILL PERSIST AS COLD AIR
STRATOCUMULUS REDEVELOP DURING THE LATTER PERIOD OF THE FORECAST.
