| - | Message 1's have been issued for the entire District until 10:00pm. |
| - | Thunderstorms have formed over the foothills and Palmer Divide early this afternoon, and a new line of thunderstorms is beginning to develop along a convergence boundary near the southern and eastern fringes of the District. Storm chances will continue to increase across the District through the afternoon, with the potential for outflow-triggered thunderstorms from these early storms. |
| - | Storm motions are generally to the E/NE at 10-15mph, but storms could potentially stall along convergence boundaries and produce heavy rainfall. The threat for stronger thunderstorms could increase late this afternoon and early this evening due to outflow boundaries reaching the District from the north and ushering in deeper moisture. |
WORST CASE SCENARIO: A strong thunderstorm could stall along a wind convergence boundary and produce heavy rainfall of up to 2.75" in 90-120 minutes.
