COLORADO/WYOMING BORDER.  THE STRONGEST THUNDERSTORM ACTIVITY HOWEVER
WAS LOCATED NORTHEAST OF CHEYENNE WYOMING.

THE AIRMASS OVER COLORADO REMAINED MOIST AND UNSTABLE.  DUE TO THE
STRONG THUNDERSTORM DEVELOPMENT IN SOUTHEAST WYOMING...THE POTENTIAL FOR
DEVELOPING OUTFLOW BOUNDARIES INTO NORTHEAST COLORADO EXISTS.  IN
ADDITION...A WEAK SURFACE TROUGH REMAINED ANCHORED ALONG THE FRONT
RANGE AND PALMER DIVIDE AREAS THIS AFTERNOON.  THESE FEATURES WILL
ACT AS FOCUSING MECHANISMS FOR ADDITIONAL THUNDERSTORM DEVELOPMENT.

SCATTERED THUNDERSTORMS WILL CONTINUE TO DEVELOP IN THE MOUNTAINS...
FOOTHILLS AND PALMER DIVIDE AREAS THIS AFTERNOON.  A FEW STORMS
HAVE ALSO DEVELOPED ALONG AND EAST OF THE URBAN INTERSTATE 25 CORRIDOR
...FROM FORT COLLINS NORTH TO THE WYOMING BORDER...BUT HAD WEAKENED.

THESE STORMS MAY BECOME SEVERE LATER THIS AFTERNOON AND EVENING
PRODUCING DAMAGING WINDS IN EXCESS OF 60 MPH AND LARGE HAIL.  DEADLY
LIGHTNING AND LOCALLY HEAVY RAIN ARE ALSO POSSIBLE WITH THESE STORMS...
SO SOME MINOR STREET FLOODING IS ALSO POSSIBLE.

MOST OF THE THUNDERSTORM ACTIVITY THIS AFTERNOON WILL DEVELOP WEST
OF A LINE FROM STERLING TO AKRON TO LIMON.  HOWEVER...SOME ISOLATED
THUNDERSTORM ACTIVITY MAY DEVELOP EAST OF THIS LINE AFTER 4 PM.

HOWEVER WAS LOCATED IN SOUTHEASTERN WYOMING AND IN SOUTHERN ELBERT
COUNTY.

THE AIRMASS OVER COLORADO REMAINED MOIST AND UNSTABLE...BUT
THUNDERSTORMS HAVE BEEN SLOW TO DEVELOP ALONG THE URBAN CORRIDOR

THE BEST LOW LEVEL MOISTURE EXTENDS FROM NEAR HEREFORD IN NORTHEAST
WELD COUNTY TO AKRON TO LIMON.  A FEW THUNDERSTORMS MAY BECOME
SEVERE ALONG AND EAST OF THIS LINE LATE THIS AFTERNOON AND EVENING.
ANY OUTFLOW BOUNDARIES GENERATED FROM THE THUNDERSTORMS IN SOUTHEAST
WYOMING OR IN SOUTHERN ELBERT COUNTY WILL HELP TO SPAWN THUNDERSTORM
DEVELOPMENT.

ALTHOUGH MOST OF THE STORMS WILL STAY BELOW WARNING CRITERIA...A FEW
OF THESE STORMS MAY BECOME SEVERE LATER THIS AFTERNOON AND EVENING
PRODUCING DAMAGING WINDS IN EXCESS OF 60 MPH AND LARGE HAIL.  DEADLY

ALONG THE URBAN CORRIDOR IS NO LONGER ANTICIPATED.
