| - | Message 1's have been issued for the entire District, valid until 10:00pm this evening. |
| - | Showers and thunderstorms developed during the late-morning hours over the mountains and foothills, ahead of an upper-level disturbance arriving from the W. Storm activity will steadily propagate E over the coming hours, with a few rounds of showers and thunderstorms possible over the District this afternoon and evening. |
| - | Faster steering flow should limit the threat for widespread heavy precipitation, but stronger thunderstorms will likely produce moderate to locally-heavy rainfall. Showers and storms will decrease after sunset, but a few could linger into the early-overnight period as the trough axis slowly clears the area. |
WORST CASE SCENARIO: Multiple waves of strong storms impacts same area, resulting in rainfall up to 2.30" in 60-90 minutes.
