AREAS AFFECTED...ERN NM AND S PLAINS OF W TX

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 050124Z - 050230Z

A NEW WW WILL LIKELY BE REQUIRED FOR PORTIONS OF ERN NM AND PARTS OF
S PLAINS OF W TX.  

TSTM CLUSTERS ARE BEGINNING TO CONGEAL INTO AN MCS WITH CURRENT
MOTION 340/20.	GIVEN THAT THE LOW LEVEL JET IS FORECAST TO
STRENGTHEN AND POINT INTO ERN NM AND WCNTRL TX...THIS COMPLEX IS
LIKELY TO TURN ESEWD AND MOVE ALONG INSTABILITY GRADIENT INTO THE
SRN PORTIONS OF THE TX PNHDL AND INTO THE S PLAINS DURING THE NEXT
