...FLASH FLOOD WATCH THIS AFTERNOON OVER THE FRONT RANGE FOOTHILLS
AND PALMER DIVIDE...

THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTHEAST AND NORTH CENTRAL
COLORADO.

.DAY ONE...TODAY AND TONIGHT

SHOWERS AND A FEW THUNDERSTORMS WITH HEAVY RAIN ARE EXPECTED TO
OVERSPREAD THE AREA LATE THIS MORNING AND AFTERNOON. SOME AREAS
HAVE ALREADY SEEN SIGNIFICANT RAINFALL AND SATURATED
SOILS...INCLUDING PORTIONS OF THE FOOTHILLS AND PALMER DIVIDE
AREA FROM DOUGLAS COUNTY INTO EASTERN ELBERT COUNTY. AS A
RESULT...THOSE LOCATIONS WILL BE MOST SUSCEPTIBLE TO FLASH
FLOODING AS THE SHOWERS AND STORMS INCREASE THROUGH THE AFTERNOON.
MINOR URBAN FLOODING WILL ALSO BE POSSIBLE WITH ANY OF THE HEAVIER
SHOWERS OR STORMS.

A DEEP PLUME OF MOISTURE COMBINED WITH AN UPPER LEVEL DISTURBANCE
WILL BRING THE LOCALLY HEAVY RAINFALL AND POTENTIAL FOR FLASH
FLOODING. STAY TUNED TO THE NATIONAL WEATHER SERVICE OR YOUR LOCAL
NEWS MEDIA FOR THE LATEST UPDATES AND POSSIBLE WARNINGS. IF
FLOODING IS OBSERVED...TURN AROUND DONT DROWN.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY

THE COOL AND WET WEATHER PATTERN IS EXPECTED TO CONTINUE OVER
NORTHEAST COLORADO THROUGH THIS WEEKEND. MOIST SOUTHWESTERLY FLOW
ALOFT WILL CONTINUE EACH DAY WITH DAYTIME HEATING CAUSING SHOWERS
AND THUNDERSTORMS TO DEVELOP. TEMPERATURES WILL BE HELD COOLER
THAN NORMAL BY THE MOSTLY CLOUDY SKIES. THE THREAT OF SEVERE
WEATHER WILL BE MINIMAL...BUT LOCALLY HEAVY RAINFALL WILL BE
POSSIBLE EACH DAY WHICH MAY CAUSE SOME FLOODING PROBLEMS.

OVER THE WEEKEND...AN UPPER LEVEL WEATHER DISTURBANCE IS FORECAST
TO MOVE ACROSS THE STATE WHICH WILL INCREASE THE COVERAGE AND
INTENSITY OF RAINFALL ON SATURDAY AND SUNDAY. THIS WEATHER SYSTEM
WILL ALSO BRING COOLER TEMPERATURES TO THE STATE WHICH MAY DROP
SNOW LEVELS DOWN TO THE HIGHER FOOTHILL LOCATIONS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
HOWEVER...REPORTS OF HEAVY RAINFALL OR FLOODING PROBLEMS WILL BE
APPRECIATED.
