Very good news if that holds out. The supercell wagon train is headed in this general direction.

Yeah - that's the one that *could* take a ride up Hwy 21 toward BCS.

Areas affected...portions of central Texas

Concerning...Tornado Watch 54...

Valid 212232Z - 220000Z

The severe weather threat for Tornado Watch 54 continues.

SUMMARY...The severe threat continues across Tornado Watch #054.
Large hail, damaging gusts and tornadoes may accompany any mature
storm within the watch. A corridor of greater severe potential is
likely developing near Austin, TX and will progress northeast
through the remainder of the afternoon.

DISCUSSION...Multiple supercells, thunderstorm clusters, and linear
segments have developed across the western portions of Tornado Watch
#054 over the past couple of hours, with a history of tornadoes near
Jacksboro and Bowie Texas. Storms continue to develop ahead of a
Pacific front/dryline just west of the I-35 corridor, and are
advancing east into a buoyant airmass. These storms are also
progressing toward the axis of the low-level jet, where greater
moisture and low-level shear exist (per 22z mesoanalysis). 20Z RAP
forecast soundings (valid for 22-00Z) show large, curved hodographs
downshear of the ongoing storms). As such, tornado potential is
expected to increase through the remainder of the afternoon into the
evening hours.

Of particular concern are the supercells along a line from Burnet to
Guadalupe Counties, which are tracking in an thermodynamic
environment characterized by 2000+ J/kg MLCAPE.
Given the storm mode
and aforementioned buoyancy/shear, a heightened tornado threat may
develop. Any supercell that becomes dominant/discrete (relatively
pristine inflow) will have the greatest risk for producing strong
tornadoes, and a long-lived, long-tracked tornado cannot be
completely ruled out.

The Luling storm is very impressive. Dynamics are not as strong that far south but there will be little cutoff of southerly flow which could maintain it for a little while.

With this system continuing to move north and east, do you think the worse part of it will bypass the Houston area?

We need that storm by lulling to fizzle, dont like the NE movement its making, if that stable air doesnt come into fruition, we could be in some big trouble

The worst part of it is supposed to be north and northwest of Houston but that means very little honestly. Your area could almost just as easily see something significant just like the moderate area could. Don’t let your guard down. Harris County is still definitely in play.

The supercells ongoing right now are not supposed to go towards Houston and were never forcasted to.Redevelopment of storms is expected later tonight once the front gets closer and that is when a majority of the area will need to watch for severe weather and flooding.
