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

Del Rio, TX (KDRT), launched 12:00Z, 11.3 hours before the alert went out and 149 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Midland/Odessa, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 1, 2:12 PM CDT, 4 hours 8 minutes earlier.

Area forecast discussion, Jul 1, 2:12 PM CDT, 4 hours 8 minutes before

Area Forecast Discussion
National Weather Service Midland/Odessa TX
212 PM CDT Wed Jul 1 2020

.DISCUSSION...
Dryline is positioned over the central Permian Basin down to the
Lower Trans Pecos with moist SW flow aloft on the base of the broad
trough over the western US. This is the last day of the current
pattern as we begin to shift into a prototypical July setup as
ridging returns back over the SW US and we begin to see a
decreasing threat of convection for most of the region. Today is
the best chance of precip the next several days for the Lower
Trans Pecos and the eastern half of the Permian Basin. Guidance is
consistent on developing an area of storms to the east of the
dryline with moderate instability on the order of 2000-3000 j/kg
of MLCAPE over the areas mentioned above. Given the steep lapse
rates present over the low to mid levels, coupled with the energy
present from afternoon heating, a marginal severe risk will
encompass the farthest eastern edges of the forecast area. Large
hail and damaging winds will be the primary concerns.

After today, focus of convection will shift to the west and
northwest of the Permian Basin with SE NM and the western high
terrain as the best opportunity to see afternoon and evening storm
development. As the ridge axis strengthens over the weekend and into
next week, it's going to be tough to maintain much in the way of
convective development outside the Davis/Guadalupe mountains
starting Friday through the extended.

Temperatures will remain above normal through the extended with a
slight decrease for Thu/Fri, rebounding back to widespread triple
digits Saturday and beyond. The dog days of summer are here and here
to stay.
