THIS OUTLOOK PERTAINS TO THE FOLLOWING COLORADO COUNTIES

ALAMOSA    BACA      BENT     CHAFFEE  CONEJOS      COSTILLA

...THUNDERSTORMS BUILDING OVER THE NORTH CENTRAL MOUNTAINS EARLY THIS
AFTERNOON...

RADAR AND SATELLITE IMAGES EARLY THIS AFTERNOON SHOW A BROAD AREA OF
THUNDERSTORMS OVER THE NORTH CENTRAL COLORADO MOUNTAINS MOVING TOWARD
THE PIKES PEAK REGION.  THESE STORMS ARE DEVELOPING IN ADVANCE OF AN
UPPER LEVEL DISTURBANCE CLIPPING NORTHWEST COLORADO.  AS THE AFTERNOON
PROGRESSES...THESE STORMS ARE EXPECTED TO SPREAD INTO THE PIKES PEAK
REGION AND THEN CONTINUE SOUTH AND EASTWARD.

THE WATER CONTENT OF THE ATMOSPHERE OVER COLORADO IS BETTER THAN 150
PERCENT OF NORMAL IN SOME CASES.  CONSEQUENTLY...THE MAIN THREAT FROM
STORMS TODAY IS AGAIN HEAVY RAIN.  ADDITIONALLY...WIND GUSTS TO 45 MPH
AND HAIL UP TO 3/4 INCH IN DIAMETER ARE ALSO POSSIBLE FROM STORMS
TODAY.

DUE TO MORE FAVORABLE WIND SHEAR...THERE IS A CHANCE THAT A FEW CELLS
COULD REACH SEVERE LIMITS OVER SOUTHEAST COLORADO THIS AFTERNOON.
HOWEVER...ANY SUCH WEATHER IS EXPECTED TO BE ISOLATED SO SPOTTER
ACTIVATION IS NOT EXPECTED.  SPOTTER REPORTS FOR HEAVY RAINFALL |OR
FLOODING WILL STILL BE NEEDED.
