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.

.SHORT TERM...
(Rest of today through Wednesday)
Issued at 1152 AM CDT Tue Sep 8 2026

High pressure has solidly returned over the southeast and we'll see
drier and hotter conditions today through a chunk of the day
Thursday. Highs today will reach into the low 90s with partly sunny
skies. Heat index values will reach near 100 degrees this afternoon,
so be sure to stay hydrated and shaded if outdoors. Quiet and warm
overnight with lows in the 70s and a few isolated instances of fog.
The high pressure bullseye will be directly overhead Wednesday,
making it the hottest day we'll experience this week. Portions of
northwest Middle TN could see heat index values around 105 Wednesday
afternoon, prompting a heat advisory that will be in effect from
10am to 7pm. Similar to today, be sure to take your precautions if
you have outdoor interests.

&&

.LONG TERM...
(Wednesday Night through next Tuesday)
Issued at 1152 AM CDT Tue Sep 8 2026

High pressure will start to break down on Thursday ahead of a
pattern change that will push a front through the area. Before this
front however, Thursday will still be quite hot. Highs will remain
in the low to mid 90s with heat index values slightly lower, but
still in the triple digit range. A shortwave will dip into the area
Thursday afternoon, bringing a more widespread chance for rain and
storms back into the forecast. Rain chances will jump up to the 60-
80% range Thursday evening into Friday out ahead of a weak cold
front that will eventually push through Friday. The threat for
severe weather with this system continues to look low, though there
will be a bump in bulk shear values to around 30 kts. Mid-level
lapse rates are poor, generally less than 6 C/Km, but ample
instability and lift will be in place to help get some storms going.
The strongest storms could produce gusty winds. Low to medium rain
chances will continue through the day Friday as the front pushes
southeast with chances areawide between 30-50%. Moving into the
weekend, weak shortwaves will continue to dip into the area, keeping
20-40% rain and storm chances in the forecast through Sunday. High
pressure will also start building east back into the area, sending
our temperatures gradually back up into the mid 90s by Sunday.
