Dew points into the low 70s in east Texas. Sun starting to peak through the broken sky allowing for some surface heating. Temps in the low 70s but warmer than expected at 77 degrees down in Huntsville and advecting north. Conditions getting favorable.

First Louisiana tornado warning of the day about to cross Toledo Bend and pick up some tamales in Zwolle.

Pissy looking cell with a decent couplet.

In their discussion with that mesoscale discussion, SPC mentioned that PDS wording is being considered for that upcoming tornado watch.

quote:

SUMMARY...Threat for supercells capable of all severe hazards
continues across Tornado Watch 582. A downstream Tornado Watch will
likely be needed across southern AR, northwest LA, and
east/southeast TX.

DISCUSSION...Recent surface analysis places a triple point low about
20 miles east of PRX, with a cold front extending southwestward from
this low through central TX. A warm front also extends southeastward
from this low through northwest and central LA (delineated well by
the 65 deg F isodrosotherm). Thunderstorm activity along the cold
front has weakened over the last hour or so, while showers have
increased throughout the warm sector. Most of these warm sector
showers have not strengthened significantly. However, very recent
trends have signaled some strengthening with the storms in Anderson,
Houston, and Robertson Counties, evidenced by increasing
reflectivity and lightning activity. Given their placement in the
warm sector, some additional strengthen/maturing into supercells is
possible.

The warm front is expected to continue slowly lifting northward
while the cold front advances eastward. This will take the warm
sector farther east into more of east/southeast TX, northwest LA,
and southern AR through this evening. As such an additional Tornado
Watch will be needed for portions of the region within the next hour
or so. Given the favorable parameter space, PDS wording is being
considered.
