MID-UPPER LOW...NOW CENTERED OVER NRN MEXICO AND THE AZ/NM BORDER
AREAS...EJECTS NEWD TO THE SRN HIGH PLAINS BY EARLY SUNDAY. ZONE OF

NWD/NEWD ACROSS OK AND INTO KS/AR THROUGH THE PERIOD. WITH THE
POSSIBLE EXCEPTION OF NEAR SURFACE-BASED STORMS TAKING FORM LATE IN
THE PERIOD NEAR THE TX GULF COAST...MOST STORMS WILL BE ROOTED ABOVE
A STABLE BOUNDARY LAYER AND FUELED BY MEAGER MUCAPE AOB 500 J PER

THE OUTSIDE CHANCE FOR ISOLD SMALL HAIL WITH SOME OF THE STRONGER
TSTMS.

SEVERE STORMS BUT A ROGUE GUST AND/OR SMALL HAIL CANNOT BE
COMPLETELY RULED OUT.
