Very interesting read on afternoon AFD from FWD, discussing thunder sleet.

Deep E TX could really get hammered tomorrow night.

Yes. Very, significant LIs for this kind of scenario.

Just about every single parameter I can think of is lined up for a (possibly) catastrophic ETX ice storm. I don't want to overstate myself, but I feel even these most reliable winter wx models are still underdoing the accumulation potential with such a powerful incoming SS trough for this winter wx setup.

That's also why I still would not let my guard down at all. Even in CTX or Austin/San Antonio region.

Of course right as I say that, this run is warmer.  Sleet profile showing almost 3 inches just to northwest....

There's this one other model RRFS-A or Rapid Refresh Forecast System (Prototype A) is also showing a huge ice storm like HRRR or even more aggressive. but personally I have no idea how reliable it is. Maybe treat it like a worst-case outcome.

Storms in south Texas with the initial wave may rob some moisture somewhere in E/NE Texas. Something that may limit total precip from 1.5"-2" down to maybe 1" in some places.

20z HRRR colder....ok maybe there's a chance for some decent ZR

Notably drier than 12z if I'm not mistaken

Interesting. I was looking at 13z vs. 20z and looking at total precip 20z looks juicier.

March 2014 featured very heavy sleet and lots of lightning where I was living in Lindale. Being in a metal bardo at the time the combo of heavy sleet and frequent thunder was wild. This area could see similar situation again but much longer lasting.

Was there also CG lightning going on up there back then that night?

It was just incredible when I saw 2 simultaneous CG strikes (likely positive-charged because they were pretty thick bolts), in just over 35 F wx about a mile from my backyard down here. I didn't have access to detailed lightning strike data online back then.

I honestly dont recall.
