   Mesoscale Discussion 0141
   NWS Storm Prediction Center Norman OK
   0950 PM CST Wed Feb 08 2023

   Areas affected...Southeast LA into southern MS

   Concerning...Tornado Watch 32...

   Valid 090350Z - 090445Z

   The severe weather threat for Tornado Watch 32 continues.

   SUMMARY...The risk of an isolated strong to severe storm continues
   across parts of Tornado Watch 32. A downstream watch is not
   currently expected, though convective trends are being monitored.

   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
   generally being aided by a plume of broad low-level warm advection,
   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
   threat with any deeper/persistent updrafts. Overall, the threat
   appears localized, and a new watch is not currently expected
   downstream of Tornado Watch 32. However, convective trends will be
   monitored.
