Areas affected...Southeast TX
Concerning...Severe Thunderstorm Watch 358...359...
Valid 311045Z - 311215Z
The severe weather threat for Severe Thunderstorm Watch 358, 359
continues.
SUMMARY...A strong to isolated severe wind threat should persist
across southeast Texas as a QLCS shifts southeastward towards the
Middle to Upper Texas Gulf Coast.
DISCUSSION...Slowing forward speed to around 35-40 kts, along with
gradually warming cloud tops suggests the arcing QLCS largely
remains strong to marginally severe. Surface gusts of 45-60 mph have
been common along the eastern two-thirds of the QLCS arc. Recent
HRRR runs insist on a potential secondary surge towards the Middle
to Upper TX Gulf Coast before it moves offshore. It is plausible
that this could occur given the presence of a relatively pronounced
MLCAPE gradient from a plume of large buoyancy still over south TX.
But recent observational trends suggest this scenario may becoming
less likely.
