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 Austin/San Antonio, TX wrote its last area forecast discussion before this severe thunderstorm warning went out at May 26, 2:51 PM CDT, 2 hours 12 minutes earlier.

Area forecast discussion, May 26, 2:51 PM CDT, 2 hours 12 minutes before

Area Forecast Discussion
National Weather Service Austin/San Antonio TX
251 PM CDT Tue May 26 2020

.SHORT TERM (Tonight through Wednesday Night)...
Drier air has worked into the area, and as we all recover from the
wet pattern over the past several days. This afternoon and evening
should remain mostly dry and uneventful. Temperatures reach the low
80s this afternoon, and low to mid 60s tonight. Tomorrow is a
different story as the low that spins over Texas, and drifts
slightly east, leaving the area under northwestern flow aloft. With
eventual southerly flow at the surface, shear values increase to
greater than 60kts. As high shear and vorticity propagate around the
low, South Central Texas is under the threat for severe storms, yet
again. Moderate instability across the region upwards of 2200J/kg of
CAPE, as the daytime further destabilizes the atmosphere.

Based on these factors, the Storm Prediction Center has the
northeastern portion of our CWA, including the Austin metro area, in
an enhanced risk for tomorrow evening. San Antonio's metro area, in
the slight risk area, will also have to be vigilant with evolving
weather conditions.

Initial development may start out as discrete cells in the Hill
Country, where very large hail will be the main threat. Should these
cells congeal as they progress and become more linear, damaging wind
will become the main threat, though the chance for large hail still
exists. Also, given the amount of shear generated, tornadoes may be
possible.

Activity should progress overnight, tomorrow night before
dissipating. Overnight lows that night will be in the upper 60s.

&&

.LONG TERM (Thursday through Tuesday)...
North flow will continue on the backside of the upper low on Thursday
with a continued chance of isolated showers and storms. Overall
coverage is not expected to be too high. The slight chance of rain
will shift to the south and southwest counties for Friday through
Sunday as moisture becomes a bit scoured for the remainder of the
area as the upper low departs and ridging begins to build back into
the region. The ridge is expected to center over the region
Monday/Tuesday with dry weather expected across the entire area.
Temperatures will be in the 80s and lower 90s for most of the
extended forecast period.
