Time	Report	Where	Remark

NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in.

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.

The nearest sounding before it

Fort Worth, TX (KFWD), launched 12:00Z, 7.4 hours before the alert went out and 5 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE FORT WORTH TX
1050 AM CDT THU JUN 13 2002

THE PRIMARY CONCERN FOR THIS FORECAST UPDATE IS MOVEMENT OF MCS OVER
SOUTHWESTERN OKLAHOMA/WESTERN RED RIVER VALLEY AT THIS TIME. CORFIDI
VECTORS SUGGEST A SLOW SOUTHWARD PROPAGATION OF THE MCS. HOWEVER...
VEERED AND WEAK LOW LEVEL JET...AS INDICATED BY DATA FROM KDYX AND
KFWS VWPS...SUGGEST THAT FURTHER INTENSIFICATION IS NOT LIKELY.
FURTHERMORE...DISTANCE BETWEEN OUTFLOW BOUNDARY/GUST FRONT AND
INITIAL CONVECTION IS INCREASING WITH TIME...ALSO SUGGESTING THAT
SYSTEM WILL NOT INTENSIFY. LATEST DATA FROM LAPS INDICATES THAT CIN
HAS BEEN DECREASING RAPIDLY THIS MORNING...AND THIS...ALONG WITH
INCREASING INSTABILITY...MAY HELP TO MAINTAIN THE SYSTEMS CURRENT
STRENGTH. WITH ALL OF THIS IN MIND...WILL INCREASE AFTERNOON POPS
SLIGHTLY (TO 40%) FOR AREAS FROM I-20 NORTH TO THE RED RIVER...
INCLUDING DFW...AS THIS IS AREA MOST LIKELY TO BE AFFECTED. MAXIMUM
TEMPERATURE AND WIND FORECAST SEEMS TO BE ON TRACK...WITH NO OTHER
CHANGES PLANNED.

.FWD...NONE.
