What was reported inside it
| Time | Report | Where | Remark |
|---|---|---|---|
| Apr 10, 9:40 PM CDT | HAIL 0.5 | 16 S Marathon, TX |
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
Del Rio, TX (KDLF), launched 00:00Z, 2.2 hours before the alert went out and 234 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.

AAWhat 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 Apr 10, 5:52 PM CDT, 3 hours 21 minutes earlier.
Area forecast discussion, Apr 10, 5:52 PM CDT, 3 hours 21 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX 552 PM CDT Fri Apr 10 2015 .DISCUSSION... See 00z aviation discussion below. && .AVIATION... Areas of rain and thunderstorms are expected to expand northward after 00z to include southeast New Mexico and the Permian Basin. This convection is expected to shift eastward tomorrow, but MAF and FST will still have a slight chance of thunderstorms in the afternoon. There is a chance of low ceilings coming into the area tonight around 12z with the best chance being in HOB. Winds will generally be out of the south to southeast throughout the period and should decrease in strength overnight then increase again Saturday afternoon. && .PREV DISCUSSION... /ISSUED 150 PM CDT Fri Apr 10 2015/ DISCUSSION... SE-E surface winds have increased across the Trans Pecos/PB this PM as surface high moves e and surface pressure falls. Upslope flow per mesoscale models (TTU WRF, NAM12, HRRR) looks well organized, enuf so that dwpnts will increase to near 50 on on east slopes of Davis Mtns and M50s thru Glass Mtns. Instability looks to be modulated by mid level LRs of 7.5 C/KM and 0-1km CAPES increase by 00Z to near 1500 J/KG in said area. Looks to be a good set-up for tstms to initiate in the mtns where SB CINH not much of an issue and then move e-ne. Kinematics are also favorable for severe wx (large hail) with 0-6 km bulk shear 40-50kts. In this set-up, the surface thermal ridge and axis of highest dwpnts are near co-located. HRRR develops QPF at 22Z NW of FST and depicts what may well be a right-moving supercell across Pecos Co later this PM. Overnight there is an indication that the arrival energy assocd shrtwv trof in the sw flow aloft and 40kt LLJ may renew the development of convection, especially s of I-20. Convective potential will wane Sat, but still exists. Isold-Sct tstms INVOF Davis/Glass Mtns and across the ern PB, respectively. Sunday more robust PoPs are warranted with backed mid level flow ahead of an upper low sw of El Paso City, helping to hold low level mstr in place. 5h jet of 50-60kts will help provide lift. 0-6km bulk shear increases late, but LR/s are not very good, so for now severe potential looks to be minimized. There's enuf of a backed flow/mstr/potential for rain cooled air to keeps temps INVOF of normal ranges thru Sunday. Said low will lift newd to w-nw of MAF and this will increase the PoPs Monday n of the area, moreso in the LBB area. However cool mid levels near the center of low will be enough to keep sct PoPs, especially along n of I-20. An assocd cold front will pass thru the area either Mon PM or Mon night, so cooler and drier Tue. Another front will be possible Wed night/Thursday morning, so cool/dry for Thur PM. We'll watch for the potential for low level mstr return Friday which will augment PoPs. && .MAF WATCHES/WARNINGS/ADVISORIES... NM...NONE.
