...East Texas into Louisiana...
Moderately strong southwest flow aloft will persist over the area
along with warm, moist southerly low-level flow. This is expected to
counteract/stall the front, perhaps resulting in a weak surface wave
along it. Models are in good agreement depicting a zone of
thunderstorms developing by late morning through afternoon across
east TX, continuing into western LA. Low-level shear appears
marginally supportive of rotating storms should storm mode be
cellular. However, a large number of storms could have negative
impacts as far as supercell potential. Any threat is expected to end
after 00Z as lift from differential divergence tied to the large jet
max to the north moves away from the area.
