The severe weather threat for Tornado Watch 582 continues.
SUMMARY...The threat for all severe hazards, including tornadoes,
continues from far southeast OK/southwest AR across northeast TX
into central TX.
DISCUSSION...Recent surface analysis places a triple point low about
25 miles west of PRX, in the vicinity of the ongoing
tornado-producing storm near Lamar County TX and Choctaw and
McCurtain Counties in OK. Mesoscale enhancement of lift and shear is
likely contributing to the persistence of this storm as it continues
through a less favorable thermodynamic environment.
A cold front extends southwestward from this low back through
central TX. A few stronger storms have recently developed in the
vicinity of this front over McLennan and Hill Counties. Undercutting
character of the front suggests that hail is likely the predominant
severe threat with these storms.
Showers have also begun to deepen farther east in Freestone County
and vicinity, with some lightning recently observed. These storms
appear to be well placed within the warm sector for further
intensification, although storm interactions could mitigate this
process somewhat. Vertical shear remains strong and any storms that
can persist and mature within this environment could become
supercells capable of all severe hazards, including tornadoes.
