Small cell now on radar just east of Carlsbad. This is right on the dryline- and on the western end of the weak ESE-WNW boundary from HOB to MAF. Best combo of surface winds and T-TD spreads are near HOB and Andrews. If I were out- that is where I would be. Explosive supercell development expected in the next 1-2 hours. Tornado threat looks to be fair to good.
