OVER AN AREA FOR SEVERAL HOURS. THE MAIN AREA OF RAIN IS EXPECTED
TO MOVE FROM THE MOUNTAINS ONTO THE PLAINS BY LATE TONIGHT...BUT
ADDITIONAL THUNDERSTORM DEVELOPMENT IS EXPECTED OVER THE MOUNTAINS
DURING THE NIGHT SO THE HEAVY RAIN THREAT WILL CONTINUE AT LEAST
THROUGH THIS EVENING.

WIDESPREAD RAIN AMOUNTS OF ONE TO TWO INCHES ARE EXPECTED...WITH A
BIT LESS IN AREAS EAST OF STERLING AND AKRON. THERE WILL LIKELY BE
AREAS WHERE HEAVY THUNDERSTORMS DEVELOP THAT GET 3 TO 6 INCHES OF
RAIN OVER A SEVERAL HOUR PERIOD...WHICH WILL BE ENOUGH TO CAUSE
FLOODING. IT IS TOO EARLY TO TELL EXACTLY WHERE AND WHEN THIS WILL
OCCUR...BUT THE MAIN THREAT WILL BE THIS AFTERNOON OVER THE
MOUNTAINS...FROM MID AFTERNOON INTO THE EVENING OVER THE FOOTHILLS
AND FRONT RANGE CITIES...AND OVERNIGHT ON THE PLAINS.

BE POSSIBLE FOR MUCH OF THE DAY...WITH HEAVY RAIN POSSIBLE. SLOW
MOVING THUNDERSTORMS WILL BE CAPABLE OF PRODUCING ONE TO TWO
INCHES OF RAIN IN LESS THAN AN HOUR. IN ADDITION...THE EASTERLY
LOW LEVEL WINDS WILL HELP HOLD SHOWERS AGAINST THE FOOTHILLS. A
FLASH FLOOD WATCH WILL REMAIN IN PLACE FOR MUCH OF NORTH CENTRAL
AND NORTHEAST COLORADO THROUGH 6 PM WEDNESDAY.

FROM THURSDAY THROUGH MONDAY...AN UPPER LEVEL RIDGE WILL REMAIN
OVER COLORADO WITH SLIGHTLY WARMER TEMPERATURES. THERE WILL BE
