Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm 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

301 PM EST WED FEB 29 2012

.SHORT TERM...(THIS EVENING THROUGH THURSDAY NIGHT)
ISSUED AT 259 PM EST WED FEB 29 2012

ON GOING SEVERE WEATHER AS A POTENT COLD FRONT SWEEPS THRU ERN KY.
EXPECT THIS EVENT TO BE NEARLY OVER BY MIDNIGHT TONIGHT. HAVE
INITIALIZED THE FIRST 24 HR WITH THE NAM12 AND THEN BLENDED TOWARDS
THE GFS WITH GFS/ECMWF BLEND FOR THE EXTENDED. THIS WORKS WELL FOR
BLENDING WITH NEIGHBORS AND FCSTING THE EXPECTED SYSTEMS.

LOW PRESSURE OVER SERN MN HAS AN OCCLUDED FRONT INTO NRN IND AND THEN
THE FRONT SWEEPS THRU CNTRL KY...ERN TN AND ERN TX. HIGH DWPTS
SURGING INTO THE 60S IS FUELING SVR TSRA ACROSS MUCH OF THE WARNING
AREA. SHARP LINE OF LOWER DWPS NOW WORKING ACROSS THE OHIO RIVER AS
THE FRONT CONTINUES MARCHING EAST. THE OBS LINE UP WELL WITH THE
NAM12 AND HAVE INITIALLIZED THE VERY SHORT FCST. COLD FRONT FCST TO
BE NEAR THE KY/VA BORDER AROUND MIDNIGHT WITH PCPN ENDING A SHORT
TIME LATER. SAT PICS INDICATE THE CLOUDS BREAK UP QUICKLY BEHIND THE
FRONT SO EXPECTING CLEARING SKIES LATER TONIGHT. THIS WILL NOT BE A
SIGNIFICANT COOLING AS THE COLD AIR IS BOTTLED UP OVER THE GREAT
LAKES WITH OUR TRAJECTORY COMING FROM THE RELATIVELY WARM CNTRL
PLAINS. LOWS TONIGHT SHOULD ONLY DROP TO THE MID 40S...ESP SINCE THE
WINDS WILL STAY IN THE 10 MPH RANGE AND KEEP THE AIR MIXED. SOME OF
THE VERY DEEPEST VALLEYS COULD COOL TO THE LOWER 40S BUT NOT MUCH
MORE. THU WILL BE A BRIGHT SUNNY DAY WITH SW WINDS OF 5-10 MPH AND
TEMPS RETURNING TO THE MID 60S. THE NEXT WX MAKER WILL APPROACH FROM
THE SW AS A WAVE WILL FORM ON OUR CURRENT FRONT AS ANOTHER IN THIS
SERIES OF SYSTEMS DEVELOPS IN THE CNTRL PLAINS AND PUSHES A WARM
FRONT NORTH THRU THE TN VALLEY. LOOK FOR AN INCREASE IN CLOUD COVER
OVERNIGHT WHICH WILL HOLD OVERNIGHT LOWS TO AROUND 50. EXPECT TO SEE
THE FIRST OF THE SHOWERS OVER SRN KY BY DAYBREAK FRI MORNING.

.LONG TERM...(FRIDAY THROUGH WEDNESDAY)
ISSUED AT 259 PM EST WED FEB 29 2012

FRIDAY FCST LOOKS TO BE A REPEAT OF TODAY WITH A WARM FRONT PUSHING
NORTH THROUGH THE DAY FOLLOWED BY SFC LOW PRESSURE TRACKING FROM ERN
KS TO SRN WI AND DRAGGING ANOTHER SHARP FRONTAL BNDRY INTO KY. THIS
FRONT IS EXPECTED TO SWEEP INTO ERN KY FRI EVENING WITH PASSAGE
AROUND MIDNIGHT. SHOWER AND THUNDERSTORMS WILL BE FUELED BY ANOTHER
85H JET AROUND 50 KTS DRAWING TEMPS AROUND 70 WITH DWPTS BACK TO NEAR
60 AGAIN. THE 50H PATTERN HAS A SERIES OF CENERS TRACKING ALONG THE
CANADIAN/NRN PLAINS BORDER AND THEN EAST THRU THE GREAT LAKES. THE
SYSTEM ON FRI/FRI NITE IS STRONGER AND THE TROF IS DEEPER AS IT
SWINGS ACROSS THE COMMONWEALTH WHICH WILL DRAW CONSIDERABLY COLDER
AIR INTO THE REGION. HIGH TEMPS ON SAT WILL STRUGGLE INTO THE LOWER
50S AND THEN DROP TO AROUND FREEZING FOR SAT NIGHT. THIS WILL BE JUST
IN TIME AS A REINFORCING SHORT WAVE DROPS INTO THE LONG WAVE TROF
OVER THE ERN CONUS WITH ENUF ENERGY AND MOISTURE TO BRING A SHOT OF
SNOW TO THE ERN HILLS FOR SUN NITE. MOISTURE LOOKS LIMITED WITH MOST
OF THE PCPN FALLING AS RIN AND THEN CHANGING TO SNOW AS THE LAST OF
THE PCPN CROSSES INTO VA/WV. THE NEW WORK WEEK LOOKS TO HAVE A 50H
RIDGE BUILD OVER THE PLAINS AND THEN MOVE INTO THE ERN CONUS WITH A
PERIOD OF DRY WEATHER AND TEMPS WARMING AGAIN TO AROUND 60 BY WED.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z THURSDAY AFTERNOON)

LINE OF STRONG TO SEVERE STORMS APPROACHING THE TAF SITES. GUSTY
WINDS LIKELY WITH SEVERE TURBULENCE...MICROBURSTS...LARGE HAIL AND
VERY HEAVY RAIN. RADAR TRACKING WILL FCST THE LINE TO BE THROUGH THE
TAF SITES...IF NOT THE MAJORITY OF ERN KY...BETWEEN 1 AND 2 UTC.
BEHIND THE FRONT EXPECT RAPIDLY IMPROVING CONDITIONS TO VFR ALTHOUGH
THERE MAY BE SOME GUSTY WINDS UNTIL NEARLY 6 UTC.
