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

.DAY ONE...TODAY AND TONIGHT

THUNDERSTORMS WILL ONCE AGAIN DEVELOP THIS AFTERNOON OVER THE
HIGHER FOOTHILLS THEN MOVE OVER THE PLAINS BY THE MID AFTERNOON
AND CONTINUE INTO THE EVENING. WESTERLY FLOW ALOFT WILL KEEP
THUNDERSTORMS MOVING ON THEIR EASTWARD OVER THE PLAINS. 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

AFTERNOON AND EVENING THUNDERSTORMS ARE EXPECTED AGAIN ON 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 MOVE THROUGH EARLY FRIDAY MORNING PRODUCING UPSLOPE
FLOW AND A CHANCE FOR MORE WIDESPREAD RAIN THROUGH THE DAY AND
INTO FRIDAY EVENING. THERE MAY BE ENOUGH RAIN TO CAUSE RENEWED
MINOR FLOODING FROM THE RUNOFF...THOUGH THE FLASH FLOOD THREAT
APPEARS TO BE LOW. THE HIGHER MOUNTAINS ABOVE 10 THOUSAND FEET
MAY SEE 2 TO 4 INCHES OF WET SNOW.

SATURDAY THROUGH TUESDAY WILL BE WARMER. THERE WILL BE LESS
THUNDERSTORM ACTIVITY...WITH MOST OF THE STORMS OVER THE MOUNTAINS.

.SPOTTER INFORMATION STATEMENT...

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