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

.DAY ONE...TODAY AND TONIGHT

A HIGH PRESSURE RIDGE ALOFT AND A DRY AIRMASS OVER EASTERN
COLORADO WILL BRING WARM CONDITIONS TO THE REGION AGAIN TODAY.
SIMILAR TO THE PAST COUPLE AFTERNOONS...DAYTIME HEATING OVER THE
MOUNTAINS WILL CAUSE ISOLATED RAIN SHOWERS OR THUNDERSTORMS TO
DEVELOP OVER THE COLORADO HIGH COUNTRY THIS AFTERNOON AND
EVENING. RAINFALL AMOUNTS WILL BE LIGHT.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY

MOISTURE WILL BEGIN TO INCREASE AHEAD OF A STRONG UPPER LEVEL
TROUGH MOVING INTO THE GREAT BASIN ON SUNDAY. THIS WILL LEAD TO
INCREASING SHOWER AND THUNDERSTORM COVERAGE IN THE
MOUNTAINS...WHILE THE PLAINS SHOULD REMAIN MAINLY DRY. SOME SNOW
COULD FALL IN THE MOUNTAINS OVERNIGHT ABOVE 11 THOUSAND FEET.

ON MONDAY...A POTENT UPPER LEVEL SYSTEM WILL BRING SHOWERS AND
THUNDERSTORMS TO THE AREA. A FEW STORMS COULD BECOME SEVERE...WITH
LARGE HAIL AND A FEW TORNADOES POSSIBLE...OVER THE NORTHEAST
PLAINS IN THE AFTERNOON. A GOOD AMOUNT OF MOISTURE INVOLVED WITH
THIS SYSTEM WILL MAKE HEAVY RAIN POSSIBLE AS WELL INTO MONDAY
EVENING. MORE SNOW WILL BE POSSIBLE IN THE MOUNTAINS ABOVE 9
THOUSAND FEET.

DRIER WEATHER WILL RETURN FOR TUESDAY BUT ANOTHER ANOTHER WEAKER
WEATHER SYSTEM MAY AFFECT THE AREA WEDNESDAY AFTERNOON INTO
WEDNESDAY NIGHT. THIS SYSTEM WILL BRING COOLER TEMPERATURES ALONG
WITH ANOTHER CHANCE OF PRECIPITATION WITH SOME SNOW EVEN LOWER IN
THE MOUNTAINS.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
