SPC MESOSCALE DISCUSSION #0619 FOR E CENTRAL AND SERN NM / W TX
CONCERNING...SEVERE THUNDERSTORM POTENTIAL...

VALID 290326Z - 290600Z

THE THREAT FOR SEVERE THUNDERSTORMS CONTINUES IN AND NEAR WW 213.

CURRENT SATELLITE AND RADAR IMAGERY INDICATE A CLUSTER OF STRONG
THUNDERSTORMS ACROSS THE WRN HALF OF WW 213.  ANOTHER CLUSTER OF
STORMS WITH RAPIDLY COOLING CLOUD TOPS IS LOCATED OVER E CENTRAL
NM...MOVING SEWD TOWARN NRN PARTS OF WW.  

SURFACE BOUNDARY REMAINS ORIENTED ROUGHLY W TO E ACROSS THE SRN
HALF OF WW 213...WITH SURFACE-BASED CAPE REMAINING IN THE 1000 TO
2000 J/KG RANGE ACROSS MUCH OF WW.  SSWLY LOW-LEVEL JET HAS
INCREASED TO 40 KT ACCORDING TO RECENT MAF AND SJT VAD WIND
PROFILES...INCREASING LOW-LEVEL FORCING ALONG AND NORTH OF SURFACE
BOUNDARY.  WATER VAPOR LOOP INDICATES THAT UPPER DIVERGENCE
ASSOCIATED WITH WEAK MID/UPPER LEVEL FEATURE IS MOVING ACROSS ERN
NM AND W TX ATTM.  AMOUNT OF INSTABILITY AND DEEP-LAYER UVV
COMBINED WITH 35 KTS OF 0-6 KM SHEAR OBSERVED BY JAYTON PROFILER
SUGGEST THE SEVERE THREAT SHOULD CONTINUE FOR THE NEXT FEW HOURS
ACROSS THE REGION.
