SIGNIFICANT WEATHER OUTLOOK FOR NORTHEAST AND NORTH CENTRAL COLORADO
NATIONAL WEATHER SERVICE DENVER CO
120 PM MDT SUN SEP 3 2000

THIS OUTLOOK PERTAINS TO THE FOLLOWING COLORADO COUNTIES

ADAMS     ARAPAHOE     BOULDER   CLEAR CREEK   DENVER       DOUGLAS
ELBERT    GILPIN       GRAND     JACKSON       JEFFERSON    LARIMER
LINCOLN   LOGAN        MORGAN    PARK          PHILLIPS     SEDGWICK
SUMMIT    WASHINGTON   WELD

SYNOPSIS: HIGH PRESSURE HAS BUILT SLIGHTLY NORTHWARD ACROSS THE
REGION TODAY WITH MOST OF THE MOISTURE ACROSS NORTHERN SECTIONS OF
COLORADO. THERE WILL BE ENOUGH INSTABILITY ALONG WITH AMPLE HEATING
TO GENERATE ISOLATED THUNDERSTORMS LATER THIS AFTERNOON AND EVENING.
THE BEST CHANCE FOR A STORM WILL BE ACROSS THE HIGHER ELEVATIONS AND
ACROSS THE COLORADO BORDER AREAS WITH WYOMING.

LIKE YESTERDAY...THE LOW LEVEL REMAINS RATHER DRY...SO GUSTY WINDS
TO 45 MPH AND ONLY BRIEF LIGHT RAIN WILL ACCOMPANY STORMS.

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY.
