OTHER WATCH INFORMATION...CONTINUE...WW 18...


DISCUSSION...LEADING EDGE OF LARGE SCALE FORCING ASSOCIATED WITH
EJECTING MEXICAN TROUGH IS JUST STARTING TO ENCOUNTER BOUNDARY LAYER
MOISTURE PLUME /WITH DEWPOINTS IN THE MID TO UPPER 60S/ MOVING NW UP
THE RIO GRANDE VLY. EXPECT THAT MOISTURE/SURFACE-BASED INSTABILITY
WILL CONTINUE TO SPREAD NW DURING THE NEXT FEW HOURS AS WARM FRONT
STRENGTHENS ALONG A LINE FROM ROUGHLY 30 S MAF TO 30 NE ABI. UPPER
WINDS WILL LIKELY REMAIN BACKED TO NEARLY SLY AHEAD OF UPPER TROUGH.
BUT ARRIVAL OF STRONGER FLOW ALOFT /70+ KT AT 500 MB/ AND ELY
COMPONENT TO NEAR-SURFACE WINDS SUGGEST A GOOD CHANCE FOR SUPERCELLS
WITH TORNADOES...IN ADDITION TO HAIL/HIGH WIND.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 2 INCHES. EXTREME TURBULENCE AND SURFACE WIND
GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 500.
