| - | Message 2's continue valid until 9pm Saturday. The Message 3's issued earlier for SE Boulder and Broomfield Counties have been allowed to expire at 1:30am. |
| - | Thunderstorm activity diminished hours ago and light rain showers continue, mainly impacting northern areas of the District currently. Rain showers are expected to continue to slowly decrease as the overnight wears on with a generally dry period into late morning Saturday. |
| - | By 10am Saturday there will already be a chance for thunderstorms over the District with prime time from around noon to 6pm. Thunderstorms that develop on Saturday will be very capable of producing heavy rainfall. With the recent moisture it may not take as much rain on Saturday to produce excessive runoff and possibly flash flooding. |
WORST CASE SCENARIO: A weak to moderate thunderstorm is able to develop overnight with the potential to produce 0.3-0.9" of heavy rain in 10-30 minutes.
