April 2020
A little concerning that the sun is coming out again, that combined with strong inflow from the gulf would explain why models show CAPE values increasing so much over night.
Just by looking at the HRRR and whatever model Travis Herzog just showed, it looks like the squall line starts to fall apart south of I-10. I sure hope not.
Well the leftover stabilized air has definitely mixed out here. Onshore flow with puffy clouds...
I think your area will have a better shot at rain than where I’m at in west-central Wharton County. Looks like all of the models have me right on the western edge of the rain so it’s possible here I might not get anything.
The squall line is really starting to bow out , if the trend continues the line may be stronger down here than it was in Dallas/Ft Worth earlier.

Areas affected...East-central Texas...Louisiana
Concerning...Severe Thunderstorm Watch 154...155...
Valid 290656Z - 290900Z
The severe weather threat for Severe Thunderstorm Watch 154, 155
continues.
SUMMARY...A severe threat is likely to continue for several more
hours as a line of storms moves southeastward across WW 154 and WW
155. New weather watch issuance may be needed to the southeast of
the current watches.
DISCUSSION...A well-developed squall line is evident on radar from
north-central Texas arching east-northeastward across northwest
Arkansas into northwest Mississippi. The line of storms is located
on the northern edge of a moist airmass. Surface dewpoints are
highest in east-central Texas where the RAP is showing a moderately
unstable airmass. MLCAPE values are estimated to be in the 3000 to
4000 J/kg range across much of east-central Texas. For this reason,
the potential for wind damage and large hail will be greatest there
over the next few hours. Wind damage and hail will also be possible
eastward across northern Louisiana where low-level flow is stronger.
The severe threat should move southeastward to the edges of WW 154
and WW 155 by 10Z. If the intensity of the line can be sustained as
it approaches the edge of the weather watches, then a new weather
watch could need to be issued across parts of southeast Texas and
central Louisiana late tonight.

The NWS Storm Prediction Center has issued a
* Severe Thunderstorm Watch for portions of
Southern Louisiana
Far Southwest Mississippi
South-central/Southeast Texas
Coastal Waters
* Effective this Wednesday morning from 240 AM until 900 AM CDT.
* Primary threats include...
Scattered damaging wind gusts to 70 mph possible
Isolated large hail events to 1.5 inches in diameter possible
SUMMARY...A well-organized squall line will continue a general
south-southeastward progression across the region through the early
morning hours, with some additional and more isolated storms also
across south-central/southeast Texas. Damaging winds will be the
most common hazard, but severe hail is possible particularly across
the Texas portion of the Watch (south-central Texas).
The severe thunderstorm watch area is approximately along and 60
statute miles north and south of a line from 60 miles northwest of
Victoria TX to 80 miles east of Lafayette LA. For a complete
depiction of the watch see the associated watch outline update
(WOUS64 KWNS WOU6).
PRECAUTIONARY/PREPAREDNESS ACTIONS...
REMEMBER...A Severe Thunderstorm Watch means conditions are
favorable for severe thunderstorms in and close to the watch area.
Persons in these areas should be on the lookout for threatening
weather conditions and listen for later statements and possible
warnings. Severe thunderstorms can and occasionally do produce
tornadoes.
Storms seem to be maintaining their strength.

That storm out near Temple looks pretty nasty.
Just as you said that, look at it now. It weakened significantly. I’m watching the area out near La Grange now. That’s a nasty looking cell.
It's very windy here in the Heights with winds gusting at least to 50 mph,I've also seen some power flashes in the distance on the leading edge of the squall line.

Worst is done here in the Heights winds were very gusty, gusting up to 60 mph multiple times with multiple power flashes. The rain is now getting heavy though.

Any idea why the NWS radar has been hung up at 2:14am?
yeah, bad timing - there are a lot of other sources, but waking up in the midst of it & searching for it was frustrating
a while back they said "new radar" would happen some time in April, now it says April/May - hopefully soon ?
