Local storm reports filed while the alert was in force, from inside its polygon or its counties.

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

Midland Regional, TX (KMAF), launched 00:00Z, 0.5 hours before the alert went out and 104 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 Midland/Odessa TX
612 PM CDT Sun Jun 18 2017

.DISCUSSION...
See aviation discussion below.

&&

.AVIATION...
The cold front has moved s of FST, farther n post-frontal winds
are decreasing, which will be the trend into the night. Main
concern for tonight is the potential for low MVFR CIGS to develop
at MAF/HOB. Soundings from NAM12/RAP13 are insisting that CIGS
will develop with some hints in MOS data. As such we have included
TEMPO CIGS at MAF/HOB between 09Z-13Z.

&&

.PREV DISCUSSION... /issued 233 PM CDT Sun Jun 18 2017/

DISCUSSION...
The cold front came through this morning as expected, however the
trailing cool air mass was too not deep enough to prevent it from
mixing out and temperatures warming to near 100 degrees in
Midland/Odessa. Clouds and a deeper cold pool in the northern
Permian Basin have allowed temperatures to remain in the 80s and
even a few 70s, leaving me envious. The cooler air and clouds will
eventually push south tonight but the low clouds will burn off
tomorrow afternoon and we should heat back up to near normal for
this time of year, being only a few degrees cooler than today.
The ECMWF still shows a chance for precipitation tomorrow
afternoon and will continue the slight chance PoPs in the northern
CWA for this forecast.

Temperatures climb the remainder of this week prolonged southerly
flow advects in warmer air. Will keep an eye on the Gulf of Mexico
for the possibility of a tropical system developing and moving
into Texas, but at this time it does not appear as if it will have
any impact on our area except possibly making us even hotter than
currently forecast. All models are showing a cold front arriving
next weekend giving us our next chance for cooler weather and
precipitation.
