.DAY ONE...Today and Tonight

Numerous thunderstorms are expected this afternoon and tonight. There

one inch in diameter. Storm movement will be east at 40 MPH. Any
thunderstorm will be capable of producing intense rainfall rates.
Thus minor flooding is possible. The storms will be the result of an
