PARTLY TO MOSTLY CLEAR SKIES WERE PRESENT ACROSS THE TRI STATE AREA
DURING THE EARLY AFTERNOON HOURS.  WATER VAPOR IMAGERY SHOWED A DRY
SLOT OF AIR OVER THE TRI STATE AREA THAT BEGAN TO SLIDE
EASTWARD...WITH MORE MOISTURE ENTERING THE REGION FROM THE WEST.
VISIBLE SATELLITE IMAGERY SHOWED SOME CUMULUS CLOUDS DEVELOPING
ALONG A WEAK SURFACE CONVERGENCE ZONE IN EASTERN COLORADO...WHICH
COULD BE A POTENTIAL AREA FOR CONVECTIVE DEVELOPMENT LATER THIS
AFTERNOON AND EVENING.

AT THE UPPER LEVELS...FORCING ACROSS THE TRI STATE AREA LOOKS TO BE
GENERALLY WEAK WITH A RIDGE SETTING UP OVER THE SOUTHWEST PORTION OF
THE CONUS.  SURFACE FORCING WILL BE PRESENT ACROSS THE COLORADO
FRONT RANGE...WITH CONVERGENCE POSSIBLY SPARKING THUNDERSTORMS THAT
WILL TRAVEL ACROSS THE HIGH PLAINS AND INTO THE TRI STATE AREA.

RAINFALL IN SLOW MOVING THUNDERSTORMS INTO THE EVENING AND OVERNIGHT

IN ENHANCING CONVECTION...LOWER CONVECTIVE TEMPERATURES IN THE UPPER
70S WILL LIKELY BE BREACHED THIS AFTERNOON TO ERODE THE WEAK CAP IN
PLACE...WHICH WILL CHANCES FOR ISOLATED THUNDERSTORMS THAT WILL
EVOLVE INTO MORE OF A CONVECTIVE COMPLEX TONIGHT.

UPPER PROFILES WILL CONTINUE TO BE SATURATED OVERNIGHT...WHICH WILL
BRING RAIN SHOWERS AND THUNDERSTORMS WITH SUFFICIENT CAPE ALOFT TO
SUSTAIN THUNDERSTORMS.  A MID AND LOWER LEVEL JET WILL BRING CHANCES
