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

.DAY ONE...TODAY AND TONIGHT

THERE WILL BE A CHANCE OF THUNDERSTORMS THROUGH MID AFTERNOON
TODAY...THEN SHOWERS AND THUNDERSTORMS WILL BE LIKELY LATE
AFTERNOON THROUGH THIS EVENING. THIS WILL BE DUE TO TWO FACTORS...
A COLD FRONT THAT WILL PASS THROUGH THE AREA MIDDAY WITH DEEPENING
UPSLOPE CONDITIONS THIS AFTERNOON...AND A WEAK UPPER TROUGH.
INITIALLY STORMS WILL BE CAPABLE OF PRODUCING GUSTY OUTFLOW
WINDS...LATER STORMS MAY PRODUCE LOCALLY HEAVY RAIN. LATER TONIGHT
LOW CLOUDS AND PATCHY FOG WILL DEVELOP OVER THE FOOTHILLS AND
URBAN CORRIDOR...DRIVERS SHOULD BE AWARE THAT VISIBILITIES MAY BE
REDUCED IN THESE AREAS.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY

A MOIST AND UNSETTLED WEATHER PATTERN WILL REMAIN OVER THE
FORECAST AREA THROUGH MUCH OF THE WEEK WITH POTENTIAL FOR LOCALLY
HEAVY RAINFALL. SCATTERED SHOWERS AND THUNDERSTORMS WILL OCCUR
NEARLY EVERY DAY...WITH THE MOST WIDESPREAD SHOWER AND STORM
COVERAGE EXPECTED LATE MONDAY THROUGH TUESDAY.

LOCALLY HEAVY RAINFALL WILL BE POSSIBLE ACROSS THE FRONT RANGE
FOOTHILLS AND I-25 CORRIDOR MONDAY AFTERNOON AND CONTINUING INTO
MONDAY EVENING. THE MAIN FOCUS FOR HEAVIER RAIN MAY SHIFT EASTWARD
ONTO THE EASTERN PLAINS MONDAY NIGHT INTO TUESDAY. AT THIS
TIME...IT APPEARS THAT MAINLY BURN SCARS WOULD BE MORE SUSCEPTIBLE
TO ANY POTENTIAL FLOODING ISSUES.

THE THREAT OF SEVERE WEATHER WILL BE LIMITED BY MARGINAL INSTABILITY
IN THE ATMOSPHERE. HOWEVER...AN ISOLATED SEVERE STORM OR TWO WILL
STILL BE POSSIBLE ON TUESDAY WHEN WIND SHEAR INCREASES.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION WILL NOT BE NEEDED TODAY OR TONIGHT.
