   DISCUSSION...Latest regional radar data shows a broken line of
   convection with a few deep/embedded updrafts tracking northward from
   the northern Gulf of Mexico into southern LA. This activity is

   though the primary low-level jet is lifting northward into MS per
   regional VWP data. Upper 60s/lower 70s boundary-layer dewpoints over
   southeast LA and a veering wind profile in the lowest 1 km (around
   250 m2/s2 0-1 km SRH from LIX VWP) could support a brief tornado
