CONCERNING...SEVERE THUNDERSTORM WATCH 336...

VALID 261635Z - 261800Z

...MCS CONTINUES ITS SEWD MOVEMENT ALONG THE RIO GRANDE RIVER
VALLEY...

CONSIDERABLE AMOUNT OF MID LEVEL CONVECTION HAS DEVELOPED FROM SOUTH
OF DRT TO NW OF HDO...AHEAD OF LEADING EDGE OF STRONGER CONVECTION. 
THIS APPEARS TO HAVE HINDERED DESTABILIZATION SOMEWHAT AS NUMEROUS
SHOWERS AND CLOUDS HAVE SPREAD ROUGHLY 30-45 MI DOWNSTREAM OF
ORIGINAL SQUALL LINE.  STRONGEST SURGE IS NOW WEST OF THE RIO GRANDE
ACROSS NRN MEXICO.  LATEST DIAGNOSTIC DATA SUGGESTS A NARROW ZONE OF
STEEPER LOW LEVEL LAPSE RATES IS DEVELOPING WELL AHEAD OF CONVECTION
FROM NEAR VCT...NWWD TO SE OF HDO.  IF ACTIVITY CAN MAINTAIN ITS
STRUCTURE...AN UPWARD EVOLUTION IS POSSIBLE AS DAYTIME HEATING ALONG
THIS ZONE INCREASES.  IN THE SHORT TERM...SEVERE THREAT APPEARS TO
HAVE DIMINISHED SIGNIFICANTLY.
