| - | Message 1's have been issued for Adams, Arapahoe, Denver, Douglas and Jefferson Counties and will be valid until 8pm this evening. |
| - | Weak to briefly moderate thunderstorms over the foothills of Boulder County earlier today has produced a gust front that is pushing SE through the District and may be a trigger for stronger thunderstorms to develop later this afternoon. Since this gust front/outflow boundary has already passed Boulder and Broomfield Counties they are not included in the Message 1's at this time but may be added later this afternoon if conditions warrant. |
| - | Moderate to strong thunderstorms will be capable of producing heavy rainfall that may lead to excessive runoff and possibly flash flooding. Best chances for thunderstorms will be over the next 4-5hours. |
WORST CASE SCENARIO: A large or slower moving thunderstorm may result in up to 1.5" of rain in 45-60 minutes.
