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, 1.7 hours before the alert went out and 119 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, May 18, 6:39 PM CDT, 2 hours 5 minutes before

Area Forecast Discussion
National Weather Service Midland/Odessa TX
639 PM CDT Tue May 18 2021

.DISCUSSION...
See aviation discussion below.

&&

.AVIATION...
A weak surface boundary will move into HOB around 03Z with a ne
wind, elsewhere se winds except nw CNM. MVFR CIGS will be possible
at HOB and MAF, and have opted to include CIGS at HOB starting
around 11Z, could be earlier. SW surface tmw starting 15Z-19Z,
except HOB will be nw.

&&

.PREV DISCUSSION... /issued 208 PM CDT Tue May 18 2021/

DISCUSSION...
A cut off low located along the CO/NM border this morning will
slowly wobble east today and tonight moving into the Panhandle
Wednesday. After it passes east high pressure builds in from the
west.  Also on Wednesday a low over the NW will work down the coast
moving into Nrn CA Thursday and into NV Thursday night and Friday.
On Saturday this low will wobble northward lifting across ID and MT
Sunday but as it does W TX and SE NM will remain in SW flow aloft.

With recent rainfall and increased moisture temperatures will be
moderated. A weak front is expected to sag into the area tonight.
Highs in the 80s expected Wednesday... with 80s and 90s Thursday and
Friday. Readings a few degrees cooler for the weekend as rain
chances increase and more clouds expected.

As of 19z satellite shows some enhanced CU going up on a dryline
running down through Lea County to Pecos and Brewster County. Added
mention of isolated storms for this... not expecting a big dryline
event but do have a few echos on radar.  Also this evening light
rain may move down into Lea county and Nrn Permian Basin along the
front. On Wednesday will have a chance of storms over the Eastern
Permian Basin and the Lower Trans Pecos. Should be dry for the most
part Thursday and Friday with rain chances returning Saturday and
continuing into early next week. More severe wx will be possible
over the weekend.
