This worries me...
At midday, a closed upper trough continues to pivot eastward,
centered over southern New Mexico and nearby far northern Mexico,
with the exit region of a strong mid/upper-level jet (90+ kt at 500
mb) beginning to overspread central/east Texas. Cloud cover remains
rather persistent at midday within the warm sector, but this
sheltering/inhibited mixing is a contributing factor to the quick
north/northwestward advection of a moist air mass (70F surface
dewpoints) that is already becoming increasing well-established
across south-central/southeast Texas.

The dew point here in Wharton has been stuck at 69° for the past few hours. I haven’t seen any readings yet of dew points in the 70’s but I suppose it’s possible later this afternoon/evening. It’s already knocking on that door.tireman4 wrote: ↑Mon Mar 21, 2022 1:41 pm This worries me...

Radar starting to light up just west of B/CS

That stuff is still junk precip from onshore flow and not so much surface based. If anything it could help to stabilize the area a little (something to continue to monitor). The surface trough/cold front is still west of 35. That is where we will need to watch

.AVIATION [18Z TAF Issuance]...
Mix of IFR and MVFR ceilings this afternoon for a few hours, but
ceilings should return back to IFR by 00Z. A low level jet is
mixing down to the surface and causing wind gusts near 30 to 35kts
across southeast Texas. These wind gusts will persist during the
overnight hours and could lead to some LLWS at around 13-15 kft.
VCTS for most of this afternoon will transition to prevailing
TSRA during the overnight hours as front moves through. Expect
stronger and variable winds with these storms. Expect other severe
weather hazards with these storms during the overnight hours such
as hail, blinding downpours, lightning, and a few isolated
tornadoes. Front will push out of CLL and UTS first a few hours
after sunrise and push off the coast by mid morning tomorrow.
Ceilings will quickly lift to VFR after the frontal passage, but
winds will become NW at around 15kts.

Severe tstorm watches hoisted in around Abilene and Cisco. Too bad Eastland couldn't get this rain a few days ago.

You found my post there, LolCromagnum wrote: ↑Mon Mar 21, 2022 1:26 pm From S2K
CAPE is higher than expected, approaching 2,500 J/kg in Southern Texas compared to just over 2,000 J/kg.
Supercell Composite is ridiculous, the RAP model (The one they use for the Mesoanalysis on some of the thermodynamics, the HRRR is used for radar) expected a SCP of 16 in parts of Southern/SE Texas, it's at 20 just to the NW of Corpus Christi
18Z HRRR looks concerning in terms of slow moving / training storms & precip in and around the Houston metro overnight with some embedded nastier looking storms. Something to monitor.
