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.

EASTERN COUNTIES.   LATEST 88D IMAGERY SHOWS THE SHOWERS DEVELOPING
OVER PORTIONS OF REFUGIO COUNTY.  THESE STORMS ARE FORMING ALONG THE

NORTHEAST AND WEAKEN.  AS A RESULT...BRIEF NORTHWEST FLOW WILL SET
UP TONIGHT ACROSS THE FORECAST AREA AND GIVE WAY TO NEAR ZONAL FLOW
MONDAY AND TUESDAY. A WEAK MIDLEVEL SHORTWAVE WILL HELP TO BRING A
BOUNDARY THROUGH THE FORECAST AREA ON WEDNESDAY.  AT THIS TIME WILL
ONLY INCREASE THE CLOUDS.  BY THURSDAY...WEAK LIFT AND INCREASING
MOISTURE COULD PRODUCE SOME LIGHT RAIN.  THE MRF HINTS AT THE
FORMATION OF A COASTAL TROUGH DURING THIS TIME WILL KEEP RAIN
CHANCES THROUGH SATURDAY.

THIS EVENING AT WHICH POINT IT WILL BECOME NEARLY STATIONARY JUST
ONSHORE. OVERNIGHT THE TRUE FRONT WILL MOVE ACROSS THE COASTAL
AREAS, SWITCHING THE WINDS FROM SOUTHWEST TO WEST...TO NORTH TO
NORTHWEST...AND INCREASING THE OFFSHORE FLOW TO SCA LEVELS DURING
THE DAY SUNDAY.
