MESSAGE 1'S WILL BE ALLOWED TO EXPIRE AT 11:30PM
-Message 1's issued for the entire District will be allowed to expire at 11:30pm, as the threat for heavy rainfall has come to an end.
-Isolated showers and thunderstorms continued across the District this evening, following a round of heavy to severe storms during the late-afternoon hours. Large-scale lift has decreased across NE Colorado at this hour, as the associated upper-level disturbance lifts NE into Kansas and Nebraska.
-Additional isolated showers and weak thunderstorms remain possible behind the departing disturbance through about 2:00am.
STORM RAINFALL POTENTIAL AND DURATION: Showers and thunderstorms will produce rainfall amounts of 0.05-0.35" in 10-30 minutes.

WORST CASE SCENARIO: A Look Ahead: The parent low of today's smaller disturbance tracks into the Four Corners on Monday, with moisture and large-scale lift increasing once again along the Front Range. Favorable ingredients exist tomorrow afternoon and evening for stronger thunderstorms capable of heavy rainfall, likely favoring the northern portions of the District.
