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 May 11, 6:37 PM CDT, 5 minutes earlier.

Area forecast discussion, May 11, 6:37 PM CDT, 5 minutes before

Area Forecast Discussion
National Weather Service Midland/Odessa TX
637 PM CDT Mon May 11 2020

.DISCUSSION...

&&

.AVIATION...
Have Thunderstorms over/near most TAF sites at this time and
included in all TAFS. Currently a Severe Thunderstorm Watch is in
effect until midnight CDT... these storms capable of producing
large hail and wind gusts in excess of 50kts. If storms continue
to move east an AWW will be needed for MAF in the next hour or two.
Expect after 05z conditions to quieten down.

&&

.PREV DISCUSSION... /issued 231 PM CDT Mon May 11 2020/

DISCUSSION...
The steering flow this week will be text book zonal flow with
westerly winds bringing a series of week disturbances across the
area. The first weak upper trough will cause storms to develop
this afternoon and move east into the Permian Basin later this
evening. Instability and shear is enough that any storms could
become severe with large hail and strong winds the primary threat.
See SPCs SWODY1 for more details.

Tuesday dries out due to weak upper ridging then another round of
possibly severe storms is expected Wednesday with the passage of
another trough. Another one day break then a third disturbance
arrives Friday increasing rain chances again, this time mainly
for the eastern Permian Basin and lower Trans Pecos though rain
chances may be pulled back farther west in subsequent forecasts.

Temperatures throughout this week will be near normal with highs
in the upper 80s to lower 90s. The lack of an amplified upper
level ridge or strong cold front will prevent much of a departure
from the mean for temps.
