| - | Message 1's issued for the entire District will continue valid until 10:00pm this evening. |
| - | Strong to severe thunderstorms thus far today have favored the northern and eastern portions of the District, focused along a boundary of converging winds and higher surface moisture. This boundary continues to lift N over the District this evening, which will decrease the threat for additional storms into mid evening. |
| - | Focus shifts later tonight towards a cold front backing into NE Colorado. The front is relatively weak, but could provide lift for additional showers and thunderstorms overnight. With elevated moisture levels in place, heavy rainfall remains possible. Message 1's may need to be extended beyond 10:00pm to account for these details. |
WORST CASE SCENARIO: A slow-moving, strong to severe thunderstorm or training of storm cells over the same area could result in rainfall up to 1.75" in 45-75 minutes.
