SIGNIFICANT WEATHER OUTLOOK FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER CO
1200 AM MDT FRI JUL 24 1998

THIS OUTLOOK PERTAINS TO THE FOLLOWING COLORADO COUNTIES

ADAMS     ARAPAHOE     BOULDER   CLEAR CREEK   DENVER       DOUGLAS
ELBERT    GILPIN       GRAND     JACKSON       JEFFERSON    LARIMER

SUMMIT    WASHINGTON   WELD

SYNOPSIS:  ABUNDANT MONSOONAL MOISTURE AT LOWER AND MID LEVELS
REMAINS IN PLACE OVER NORTHEAST COLORADO TODAY.  CLOUD COVER AND FOG
HAVE HELD BACK SURFACE TEMPERATURES THROUGH LATE THIS MORNING...BUT
AS INCREASING SUNBREAKS DURING THE AFTERNOON WILL ALLOW READINGS TO
BEGIN CLIMBING.  AS TEMPERATURES REACH THE UPPER 70S AND NEAR 80...
THE ATMOSPHERE WILL BECOME UNSTABLE WITH RAINSHOWERS AND
THUNDERSTORMS DEVELOPING.  VERY WEAK WINDS ABOVE THE SURFACE WILL
CAUSE DEVELOPING THUNDERSTORMS TO MOVE VERY SLOWLY.  THE HIGH LEVELS
OF MOISTURE IN THE ATMOSPHERE WILL CAUSE SHOWERS TO PRODUCE LOCALLY
HEAVY RAINFALL.  THE THREAT OF HAIL FROM THUNDERSTORMS IS MINIMAL...
BUT HEAVY RAINS COULD CAUSE LOCALIZED FLOODING PROBLEMS THROUGH THE
LATE AFTERNOON AND EVENING.

LATE MORNING SATELLITE PICTURES INDICATE THAT AREAS SOUTH OF I-76
HAVE BEEN RECEIVING MORE SUN THAN AREAS CLOSER TO THE FOOTHILLS.
THESE AREAS WILL HAVE THE WARMEST TEMPERATURES BY MID-AFTERNOON...
AND SHOULD BE WHERE THE STRONGEST STORMS DEVELOP.  MORGAN...
WASHINGTON...EASTERN ADAMS AND EASTERN ARAPAHOE COUNTIES WILL HAVE
THE HIGHEST THREAT OF RECEIVING HEAVY RAINS.  RAINFALL AMOUNTS OF 2
TO 3 INCHES IN ONE OR TWO HOURS WILL BE POSSIBLE.  THE HEAVY RAINS
FALLING ON ALREADY WET GROUND FROM PREVIOUS RAINFALL MAY LEAD TO
FLOODING PROBLEMS.  AREAS ALONG THE I-25 CORRIDOR WILL SEE SHOWERS
AND THUNDERSTORMS MOVE SLOWLY OFF THE FOOTHILLS.  SOIL MOISTURE
LEVELS ARE LOWER NEAR THE FOOTHILLS...SO A SLIGHTLY LOWER THREAT OF
FLOODING PROBLEMS EXISTS THERE.

SPOTTER ACTIVATION IS NOT EXPECTED THIS AFTERNOON...BUT SKYWARN
SPOTTERS ARE ASKED TO RELAY ANY HEAVY RAIN OR FLOODING REPORTS TO
THE NATIONAL WEATHER SERVICE IN DENVER.
