Valid 160100Z - 161200Z


Thunderstorms are possible tonight over the central Gulf Coast

...01z Update...

Mid-level jet will strengthen as it translates across northeast TX
into the northern Gulf States by 16/12z. In response, weak surface
low over the northern Gulf basin should begin to lift northeast.
This feature will likely only clip the southeastern tip of LA after
midnight before approaching the AL Coast by sunrise. It appears
surface-based buoyancy will remain negligible inland, as low-level
moisture should struggle to advance onshore. 00z sounding at LIX
this evening exhibited weak buoyancy when lifting a parcel near
700mb. For these reasons, weak elevated convection remains possible
across the central Gulf Coast region the remainder of the period.
