SIGNIFICANT WEATHER OUTLOOK FOR SOUTH CENTRAL AND SOUTHEAST
COLORADO
NATIONAL WEATHER SERVICE PUEBLO CO
1155 AM MDT MON JUN 10 1996

THIS OUTLOOK PERTAINS TO THE FOLLOWING COLORADO COUNTIES:

ALAMOSA      BACA        BENT          CHAFFEE        CONEJOS
COSTILLA     CROWLEY     CUSTER        EL PASO        FREMONT
HUERFANO     KIOWA       LAS ANIMAS    MINERAL        OTERO
PROWERS      PUEBLO      RIO GRANDE    SAGUACHE       TELLER

AS OF 1130 AM...THUNDERSTORMS WERE ALREADY FORMING OVER THE
MOUNTAINS OF SOUTH CENTRAL AND SOUTHEAST COLORADO.

BY EARLY AFTERNOON...STORMS WILL BEGIN SPREADING OVER THE PLAINS.
SINCE THE AMOUNT OF MOISTURE HAS INCREASED...THUNDERSTORMS TODAY
ARE MORE LIKELY TO PRODUCE MEASURABLE RAIN.  BRIEF HEAVY RAIN
SHOWERS ARE POSSIBLE OVER THE FAR EASTERN PLAINS.

FOR MUCH OF THE PLAINS AND THE SAN LUIS VALLEY...THE MAIN THREAT
FROM THUNDERSTORMS TODAY IS STILL HIGH WIND GUSTS DUE TO
MICROBURSTS...WHICH COULD LOCALLY REACH 60 MPH.

ADDITIONALLY...IN AREAS WHERE THUNDERSTORMS FAIL TO DROP MUCH
RAIN...LIGHTNING-SPARKED FIRES WILL AGAIN BE A THREAT TODAY.

THERE IS THE POTENTIAL FOR A FEW STORMS TO PRODUCE HAIL UP TO 3/4
INCH IN DIAMETER...MAINLY NEAR THE PALMER DIVIDE AND OVER THE FAR
EASTERN PLAINS.

ALTHOUGH THUNDERSTORMS TODAY WILL PRODUCE GUSTY WINDS IN MANY
AREAS AND SOME HAIL...DAMAGING WIND GUSTS AND HAIL GREATER THAN
3/4 INCH IN DIAMETER WILL BE HIGHLY LOCALIZED.  THEREFORE...
SPOTTER ACTIVATION SHOULD NOT BE NECESSARY.
