| - | Message 1's have been issued for the entire District and will be valid through 9:00 PM this evening. |
| - | SE winds have increased surface moisture over the District through the day with dew points now in the mid to upper 40's. Thunderstorms have already initiated, some of which are strong to severe over eastern areas. Fast storm motions from WSW to ENE at around 30-35mph will help to reduce point rainfall amounts and stronger storms will also contain hail. |
| - | A slower moving thunderstorm or training of thunderstorm cells will produce the highest threats for prolonged heavy rainfall that could lead to excessive runoff and flash flooding. Strong thunderstorm cells will have the potential to produce gusty straight line winds and large hail. |
WORST CASE SCENARIO: A slower moving or training of thunderstorm cells could result in heavy rainfall of up to 1.4" in 60 minutes or less.
