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

MOVING INTO THE PERMIAN BASIN AND THE NORTHWEST BIG COUNTRY AT THIS
TIME. MODELS STILL DOING REAL GOOD IN THE SHORT TERM...BUT
CONFIDENCE IN THE FORECAST BEYOND DAY 3 IS IFFY AT BEST WITH

.TONIGHT AND TOMORROW...COLD FRONT STILL TO MOVE SOUTH THROUGH THE
NIGHT AS WAVES CONTINUE TO ROTATE OUT OF UPPER LOW FEATURE MOVING
OUT OF BAJA. ALTHOUGH SOME BREAKS IN THE PRECIPITATION IS POSSIBLE
THIS AFTERNOON AND EARLY THIS EVENING. EXPECT PRECIPITATION TO FILL

THE LATEST SATELLITE AND RADAR IMAGERY. THUS WILL CONTINUE FLOOD
WATCH FOR CURRENT COUNTIES AND EXPAND TO RUNNELS...COLEMAN AND BROWN
COUNTIES.RAIN SHOULD BEGIN TO TAPER OFF LATE TONIGHT FROM NORTH TO
