| Message 1's have been issued for the entire District and will be valid until 10:30 PM. An upper level disturbance is moving in from the N/NW and will result in a round of thunderstorms for at least northern and central areas of the District this evening. This line of storms may not sustain themselves long enough to impact southern areas of the District and there is a lower risk for heavy rainfall over Arapahoe and Douglas Counties. Storm motions will be from the NW to SE between 20-25mph which will help limit point rainfall amounts. However, training of thunderstorms are possible and may result in an extended period of moderate to heavy rain. Stronger storms may also contain hail and gusty winds. |
WORST CASE SCENARIO: Training of thunderstorm cells may produce up to 1.2" of rain in 45-60 minutes.
