VALID 302058Z - 302130Z
WW MAY BE NEEDED THIS AFTERNOON INTO THE EVENING ACROSS SERN NM AND
SW TX. DAMAGING WINDS AND HAIL WILL BE THE PRIMARY THREATS.
STRONGER SURFACE HEATING THIS AFTERNOON HAS ALLOWED THE AIR MASS TO
DESTABILIZE WITH MODERATE INSTABILITY EXTENDING FROM SW TX NNWWD
INTO ERN NM /E OF ONGOING TSTMS CURRENTLY MOVING INTO CENTRAL NM/.
THE CENTRAL NM STORMS SHOULD TRACK SEWD INTO SERN NM THROUGH THE
REST OF THE AFTERNOON/EVENING ALONG INSTABILITY CORRIDOR AND
COMBINED WITH EFFECTIVE BULK SHEAR /35-40 KT/ IS SUPPORTIVE OF
ADDITIONAL ORGANIZED STORMS. FARTHER S...ISOLATED STRONG TO SEVERE
STORMS HAVE DEVELOPED OVER THE HIGHER TERRAIN OF SW TX WHERE MLCAPE
IS AROUND 2000 J/KG AND EFFECTIVE BULK SHEAR ALSO SUPPORTS
SUPERCELLS. GIVEN THE EXPECTATION FOR FURTHER TSTM DEVELOPMENT AND
THE FAVORABLE ENVIRONMENT...A WW MAY BE NEEDED.
