The SW U.S./Mexico cutoff low is now ejecting through SW Texas, with a strong subtropical jet bending under it providing ample deep-layer shear.  Very warm and moist onshore flow from the Gulf of Mexico is impact south Texas.  At the starting time of operations, severe convection was already on-going.  Also expect additional development within the warm sector, perhaps initiating over the higher terrain of NE Mexico before moving across the Rio Grande into the U.S. later this afternoon and evening.

Our teams are operating as Corpus Christie, TX (CRP) and Brownsville, TX (BRO).  The CRP team is jumping in on active severe convection.  The BRO team is waiting for CI in their CWA and to the west in Mexico.

Here is the SPC Day 1 outlook:
