EVIDENT ON WATER VAPOR IMAGERY WITH SOUTHWEST FLOW IN PLACE FROM THE

AXIS IS IN PLACE FROM WEST TX NNEWD INTO WRN KS WHERE DEWPOINTS

MOISTURE...INSTABILITY REMAINS RATHER WEAK ATTM. HOWEVER...A 80 TO
100 KT MID-LEVEL JET LOCATED ACROSS THE CNTRL ROCKIES IS CREATING
STRONG VERTICAL SHEAR PROFILES ACROSS THE REGION. THIS MAY SUPPORT A
MARGINAL THREAT FOR STRONG GUSTY WINDS AND/OR A BRIEF TORNADO AS

FOR MARGINALLY SEVERE STORMS SHOULD BE ACROSS ERN NM AND WEST TX
WHERE INSTABILITY IS FORECAST TO BE MAXIMIZED AND STORMS ARE LIKELY
TO BE SFC-BASED IN NATURE.
