SIGNIFICANT WEATHER OUTLOOK FOR SOUTH CENTRAL AND SOUTHEAST
COLORADO
NATIONAL WEATHER SERVICE PUEBLO CO
1155 AM MDT SAT JUL 13 1996

THIS OUTLOOK PERTAINS TO THE FOLLOWING COLORADO COUNTIES:

ALAMOSA      BACA        BENT          CHAFFEE        CONEJOS
COSTILLA     CROWLEY     CUSTER        EL PASO        FREMONT

PROWERS      PUEBLO      RIO GRANDE    SAGUACHE       TELLER

OVER THE EASTERN PLAINS AND SOUTHEAST MOUNTAINS...UPSLOPE FLOW
WILL CONTINUE TODAY.  WITH A MOIST AND UNSTABLE AIRMASS OVER THE
REGION...THUNDERSTORMS WILL DEVELOP EARLY THIS AFTERNOON OVER THE
MOUNTAINS AND PALMER DIVIDE.  THESE THUNDERSTORMS WILL MOVE TO
THE SOUTHEAST OVER THE PLAINS DURING THE AFTERNOON AND EVENING
HOURS.   SUFFICIENT VERTICAL WIND SHEAR EXISTS TO ALLOW A FEW OF
THESE STORMS TO BECOME SEVERE WITH HAIL 3/4 OF AN INCH OR LARGER
AND WIND GUSTS OF 60 MPH OR GREATER.

AN UPPER LEVEL DISTURBANCE MOVING INTO THE REGION THIS EVENING
MAY HELP CONTINUE THUNDERSTORMS INTO THE LATE EVENING HOURS.

THE HEAVY RAINS OF THE PAST FEW DAYS HAVE MADE FOR VERY MOIST
SOIL CONDITIONS FOR PORTIONS OF THE SOUTHEAST PLAINS AND
SOUTHEAST MOUNTAINS...WITH A HIGH POTENTIAL FOR STREET FLOODING
AND FLOODING OF SMALL STREAMS AND NORMALLY DRY WASHES.  ALTHOUGH
THUNDERSTORMS TODAY WILL PRODUCE BRIEF HEAVY RAINS...MODERATE
MOVEMENT SHOULD HELP PREVENT FLASH FLOODING.
HOWEVER...THUNDERSTORMS THAT CONTINUE TO FORM AND MOVE OVER THE
SAME AREAS MAY STILL BRING ABOUT FLASH FLOODING.

ADDITIONALLY...POTENTIAL REDEVELOPMENT OF THUNDERSTORMS THIS
EVENING OVER THE PLAINS AND SOUTHEAST MOUNTAINS MAY PROMPT THE
ISSUANCE OF A FLASH FL,OOD WATCH FOR THIS EVENING...ESPECIALLY FOR
ANY OF THE ALREADY FLOOD PRONE AREAS THAT RECEIVE SIGNIFICANT
RAINFALL THIS AFTERNOON.
