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

.DAY ONE...TODAY AND TONIGHT

ANOTHER ROUND OF SHOWERS AND THUNDERSTORMS ARE EXPECTED TO DEVELOP
THIS AFTERNOON OVER THE COLORADO HIGH COUNTRY AND THEN MAKE THEIR
WAY EASTWARD ACROSS THE PLAINS THROUGH THE EVENING. WEAK WESTERLY
FLOW ALOFT IS IN PLACE OVER NORTHERN COLORADO...AND THIS SHOULD BE
ENOUGH TO KEEP THUNDERSTORMS MOVING ON THEIR EASTWARD TREK. SMALL
HAIL AND BRIEF HEAVY RAINS WILL BE THE PRIMARY THREATS FROM THE
THUNDERSTORMS THAT MOVE OUT OF THE FOOTHILLS AND ONTO THE PLAINS.
FURTHER TO THE EAST...THUNDERSTORMS MAY BE A BIT STRONGER. THERE
IS A SLIGHT RISK THAT THUNDERSTORMS EAST OF A LIMON TO STERLING
LINE MAY BE STRONG ENOUGH TO PRODUCE ONE-INCH DIAMETER HAIL AND
WIND GUSTS TO 60 MPH. THESE THUNDERSTORMS MAY ALSO PRODUCE HEAVY
RAIN WITH LOCALIZED FLOODING. SHOWERS ON THE NORTHEAST PLAINS WILL
GRADUALLY DISSIPATE BY MIDNIGHT.

.DAYS TWO THROUGH SEVEN...THURSDAY THROUGH TUESDAY

EXPECT ANOTHER DAY OF AFTERNOON AND EVENING THUNDERSTORMS
THURSDAY WITH THE POTENTIAL FOR STRONG STORMS OVER THE FAR EASTERN
PLAINS. HAIL AND STRONG OUTFLOW WINDS WILL BE THE MAIN THREATS.

A COLD FRONT WILL PUSH DOWN EARLY FRIDAY MORNING FOR UPSLOPE FLOW
AND A GOOD CHANCE OF HEAVIER RAIN AND ISOLATED THUNDERSTORMS
THROUGH THE DAY AND EVENING. THIS MAY INCREASE HYDROLOGIC THREATS
WITH FLOODING...MOSTLY MINOR...BECOMING A CONCERN AGAIN. THE
HIGHER MOUNTAINS ABOVE 10 TO 11 THOUSAND FT MAY SEE 2 TO 4 INCHES
OF WET SNOW.

SATURDAY THROUGH TUESDAY WILL START A SLOW WARMING AND SLIGHT DRYING
TREND. EXPECT DIURNALLY DRIVEN THUNDERSTORMS EACH AFTERNOON AND
EVENING...MOSTLY OVER THE HIGHER TERRAIN.

.SPOTTER INFORMATION STATEMENT...

SPOTTER ACTIVATION MIGHT BE NEEDED THIS AFTERNOON FOR
THUNDERSTORMS THAT DEVELOP ON THE FAR EASTERN PLAINS.
