| - | Message 1's will continue valid until 9:30 PM. The gust front/outflow boundary from storms over Larimer and Weld Counties has moved southward through the District but did not initiate strong thunderstorms within District boundaries. The strongest storms remained just N of the District over Boulder County. |
| - | As the outflow boundary from northern CO storms moved southward through the District it helped to keep shower activity active but did not generate strong storms. Now that this boundary has passed through Douglas County the threat for heavy rainfall is quickly diminishing as temperatures are cooling and the triggering mechanism for stronger storms is now well south of the area. |
| - | Additional light rain showers and weak thunderstorms will continue possible over the next 1-2 hours. The threat for moderate to strong thunderstorms with the potential to produce heavy rainfall is lowering rapidly now that temperatures are backing off but an isolated moderate to strong thunderstorm cannot be ruled out. |
WORST CASE SCENARIO: An anchored strong thunderstorm or a slower moving large thunderstorm may result in up to 1.5" of rain in 60-90 minutes.
