Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this tornado warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

Area forecast discussion, Apr 2, 3:25 PM CDT, 1 hour 38 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PADUCAH KY
325 PM CDT THU APR 2 2009

.DISCUSSION...
ACTIVE SPRING WEATHER PATTERN CONTINUES THE REST OF THIS WEEK AND
INTO THE WEEKEND...WITH TWO MAJOR SYSTEMS TO DEAL WITH...THE FIRST
ONE THIS AFTERNOON INTO THIS EVENING...AND THE NEXT LATE THIS
WEEKEND AND  EARLY NEXT WEEK.

WILL NEED TO BE AS BRIEF AS POSSIBLE DUE TO ONGOING WEATHER
SITUATION. CURRENTLY LOOKING AT SEVERE STORM/ISOLATED TORNADO RISK
TO CONTINUE LATE AFTERNOON INTO THE EARLY EVENING IN AREAS OF
WESTERN KY...SOUTHEAST ILLINOIS AND SOUTHWEST INDIANA. SURFACE LOW
WILL TRACK RIGHT UP ALONG THE OHIO RIVER VALLEY EARLY TONIGHT...WITH
MOST OF THE SEVERE STORM RISK NEAR ALONG AND SOUTH OF ITS TRACK. THE
BEST CHANCES OF ISOLATED TORNADOES WILL BE OVER THE PENNYRILE REGION
OF WESTERN KY...WHERE THE BEST COMBINATION OF SURFACE BASED
INSTABILITY AND SHEAR WILL DEVELOP...ESP BETWEEN 3 PM AND 7 PM.
AFTER SUNSET...INSTABILITIES FALL OFF RATHER QUICKLY...SO THE SEVERE
THREAT SHOULD DIMINISH. WILL ALSO NEED TO MONITOR FOR FLOODING...AS
CURRENT RADAR EST ARE OVER AN INCH AN HOUR IN THE HEAVIER PRECIP.

WINDS WILL WHIP UP ON THE BACK SIDE OF THE SFC LOW LATER THIS
EVENING INTO THE OVERNIGHT. MAY BRIEFLY REACH CLOSE TO WIND ADVISORY
CRITERIA...WITH SOME NW WIND GUSTS IN THE 35 TO 45 MPH RANGE.
HOWEVER...SHOULD LAST ONLY 2-4 HOURS...SO WILL NOT ISSUE HEADLINES
AT THIS TIME.

AFTER A PLEASANT COUPLE OF DAYS FRI...AND ESP SAT...ANOTHER SYSTEM
GETS ITS ACT TOGETHER IN THE CENTRAL PLAINS AND WILL LIKELY AFFECT
MUCH OF THE REGION ON SUNDAY. THE GFS SEEMS TO BE THE FASTEST AND
THE ECMWF THE SLOWEST WITH THE PASSAGE OF THE FRONT. BUT FRONTAL
PASSAGE SHOULD BE SOMETIME ON SUNDAY...BRINGING A GOOD CHANCE OF
SHOWERS AND SCATTERED STORMS. THE ASSOCIATED MID LEVEL LOW WILL
SWING IN BEHIND THE FRONT AND ACT TO KEEP CLOUDS AND A CHANCE FOR
SHOWERS IN THE FORECAST. AS PREVIOUS SHIFT MENTIONED...A SECONDARY
MID LEVEL LOW WILL SWING IN BEHIND THE PREVIOUS SYSTEM AND BRING A
SHOT OF BLUSTERY CANADIAN AIR WITH IT...AND ALSO SERVE TO KEEP SKIES
CLOUDY MONDAY...WITH SHOWERS AND MAYBE EVEN A SNOW SHOWERS IF THE
LOWER BOUNDARY LAYER CAN COOL ENOUGH. WOULD NOT BE TOO SURPRISED TO
SEE TEMPS STAY IN THE UPPER 30S AND LOWER 40S ALL DAY MONDAY...AS
FIERCE COLD AIR ADVECTION RESULTS IN 850 MB TEMPS PLUMMETING TO -9
TO -10 DEG C DURING THE DAY. CLOUDS NOW EXPECTED TO STAY IN MOST
AREAS EAST OF THE MS RIVER ON TUE...SO WILL KEEP TEMPS IN THE 40S
THOSE AREAS ONCE AGAIN. WILL UNDERCUT MEX MOS TEMPS SOME 10 DEGREES
OR SO AS IT HAS WAY TOO
MUCH SPRINGTIME CLIMO BUILT IN THAT FAR OUT. THIS PATTERN SHOULD
RESULT IN MAX TEMPS 20 TO 25 DEGREES BELOW NORMAL FOR THIS TIME OF
YEAR.

&&

.AVIATION...
LARGE SHIELD OF RAIN AND THUNDERSTORMS WILL OVERSPREAD ALL TAF SITES
THIS AFTERNOON. PERSISTENT AND LOCALLY HEAVY RAIN WILL EVENTUALLY
SATURATE THE LOWER LEVELS...MEANING IFR CEILINGS SHOULD BECOME
PREVALENT EARLY THIS EVENING. AS A RATHER STRONG SURFACE LOW PASSES
JUST SOUTHEAST OF THE TAF SITES THIS EVENING...WINDS WILL BACK FROM
SOUTHEAST TO NORTH. A BRIEF PERIOD OF STRONG GUSTS FROM 30 TO 40
KNOTS IS POSSIBLE AROUND 06Z...OTHERWISE GENERALLY 15 TO 25 KNOTS
THROUGH THE NIGHT. GRADUAL CLEARING WILL BEGIN FRIDAY MORNING AS
NORTHWEST WINDS BRING DRIER AIR.

.PAH WATCHES/WARNINGS/ADVISORIES...
KY...NONE.
MO...NONE.
IL...NONE.
