It all has to do with Tropical Storm Irma. Just about 24 hours ago, making landfall as a major category 4 hurricane in the FL keys. Land interaction is just what it takes to weaken a hurricane. After devastating damage, most without power and significant storm surge, Irma is now inching out of northern Florida. The bulk of the moisture is now widespread across most of Georgia. Notice how Irma is expected to turn towards the north and the west, with the center just south of western Middle Tennessee by Tuesday afternoon.PAUL TROPICAL FORECAST

Scattered rain carries on into Wednesday. As Irma departs, there will be enough lingering moisture for a few spotty showers on Thursday, especially early on in the day. A clearing trend arrives as soon as the second half of the day into Friday, Saturday and even Sunday! Another fantastic weekend on tap!WSMV 7 Day AM

Be sure and join Meteorologist Dam Thomas for updates on the timing of the rain at noon today. Chief Meteorologist Lisa Spencer will have more to come on Irma at 4,5, 6 and 10 tonight!
