Did it verify

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.

- Elevated threat (Level 2 of 4) for flash flooding this

.DISCUSSION...
Issued at 104 PM CDT Tue Jul 14 2026

The upper low will bring one more day of the potential of heavy
rainfall across portions of the area today. With PWATS of around
2.2 inches along with the upper low, we are advertising an
elevated risk for flash flooding for much of the area this
afternoon into the early evening. The upper low will retrograde
westward tonight into Wednesday and weaken. There will continue to
be chances of storms Wednesday afternoon, especially for areas
north of I-20, but expect flash flooding concerns to be
limited./15/

Thursday into early next week (Monday): Ridging aloft will again
reassert itself over the region. While this will lessen the
overall rain chances (less than 20 percent and likely on the
periphery of the region until Sunday to Monday) across the
forecast area, the trade-off currently looks to be a return to hot
humid conditions as highs areawide eventually climb back into the
mid 90s next weekend. Lows will be seasonably warm during this
period, some 3F to 6F above (73F to 76F). Increasing heat stress
still looks to be a concern. HWO heat graphics will likely be
needed, likely Friday through next Monday. With ongoing rain
concerns and cooler temperatures, holding off introduction in HWO
graphics for now but will likely be needed in subsequent forecast
cycles. /DC/EC/

.AVIATION...
