    WATER VAPOR IMAGERY THIS EVENING SHOWS A LOWER-LATITUDE SHORTWAVE
    TROUGH MOVING EWD ALONG THE AZ/NM/MEXICO BORDER AND THIS FEATURE IS
    FORECAST TO MOVE TO W TX BY EARLY FRIDAY MORNING.  A GRADUAL
    INCREASE IN SHOWERS AND THUNDERSTORMS IS EXPECTED TONIGHT ACROSS
    PORTIONS OF SERN AND CNTRL TX AS LIFT FROM THE APPROACHING
    DISTURBANCE IS COMPLIMENTED BY A STATIONARY FRONT INTERACTING WITH
    MODIFIED GULF MOISTURE AND SUFFICIENTLY STEEP MID-LEVEL LAPSE RATES.
    NONETHELESS MOST OF THIS ACTIVITY WILL PROBABLY BE RELEGATED N OF
    THE FRONT AND REMAIN WEAK.  HOWEVER...A FEW OF THE STRONGER UPDRAFTS
    COULD POSE A SMALL HAIL RISK...BUT THE THREAT APPEARS MARGINAL
    ENOUGH PRECLUDING A LOW SEVERE CATEGORICAL HIGHLIGHT.
