THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 275
CONTINUES.

SUMMARY...STRONG/SEVERE TSTMS WILL SPREAD TOWARD THE SRN PORTIONS OF
WW275 BY 03Z.

DISCUSSION...LARGE SCALE FORCING IS SPREADING ACROSS THE SRN ROCKIES
TOWARD FAR WEST TX THIS EVENING AND THIS IS PROVIDING BACKGROUND
SUPPORT FOR ONGOING CONVECTION AS IT SPREADS SEWD ACROSS NM. 
SEVERAL SEVERE SUPERCELLS ARE EMBEDDED WITHIN THE LARGER CONVECTIVE
COMPLEX...NAMELY ACROSS OTERO AND NRN EDDY COUNTIES IN SERN NM. 
LATEST WDSS MESH GUIDANCE CONTINUES TO SUGGEST LARGE HAIL IS
ACCOMPANYING THIS ACTIVITY AND WINDS RECENTLY GUSTED TO 54KT AT ATS.
 ALTHOUGH 00Z SOUNDINGS FROM EPZ/MAF DO NOT DEPICT MUCH CAPE...BOTH
PROFILES EXHIBIT STEEP LAPSE RATES AND THIS APPEARS PARTLY
RESPONSIBLE FOR THE ROBUST UPDRAFTS NOTED.  LATEST THINKING IS
LEADING EDGE OF STRONG TSTMS WILL APPROACH THE TX BORDER BY 03Z.
