What was reported inside it

Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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.

514 PM CST WED MAR 10 2010

.AVIATION...
CONCERNING TAF SITES KTUL/KRVS/KMLC/KXNA/KFYV/KFSM.
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO PROVIDE PERIODIC
IMPACTS TO MOST TAF SITES THROUGH THE MID EVENING HOURS...WITH
LOWER CEILINGS SPREADING INTO NORTHEAST OKLAHOMA LATER TONIGHT.
BROKEN STRATOCU DECK LIKELY BENEATH COLD UPPER CORE TOMORROW
ESPECIALLY OVER NE OK/FAR NW ARKANSAS.

.PREV DISCUSSION... /ISSUED 344 PM CST WED MAR 10 2010/

DISCUSSION...
GFS APPEARS TO BE TRACKING FAIRLY CLOSE TODAY AND HAVE USED A BLEND
OF THE GFS AND ECMWF FOR MOST OF THE FORECAST. PRECIPITATION WISE...
HAVE MAINLY FOLLOWED THE ECMWF. HAVE NOT STRAYED TOO FAR FROM THE
GUIDANCE TEMPERATURES BUT HAVE LEANED A LITTLE TOWARD THE COOLER
SIDE.

ONGOING EVENT STILL GIVING SIGNALS OF SEVERE ALTHOUGH THE MORE
DANGEROUS CONDITIONS APPEAR TO BE SHAPING UP JUST EAST OF OUR AREA
BUT UPPER LOW STILL TO MOVE JUST NORTHWEST OF INTERSTATE 44 AND
NEW WATCHES ARE COMING OUT IN NEXT FEW MINUTES. FORECAST WILL
INCORPORATE NEW WATCH INFORMATION.

STILL LOOKING QUESTIONABLE FOR RAIN OVER THE WEEKEND AND HAVE SIDED
TOWARDS THE ECMWF WHICH SHUNTS THE UPPER SYSTEM EARLY NEXT WEEK TO
OUR WEST AND SOUTH KEEPING THE FORECAST AREA MAINLY DRY BUT NOT
CLOUD FREE. THIS ALSO CONTRIBUTED TO THE THOUGHT TO LEAN A LITTLE
TO THE COOLER SIDE.
