I hate to make this prediction, because that's almost a guarantee it won't happen, but as of the 0Z runs this morning, all three major models now have this developing tropical system turning into a hurricane that comes ashore near the Big Bend of the Florida Panhandle. Then, instead of turning east and cutting across southern GA back out to sea in the Atlantic, the models turn it north and bring the center right up into the Chattanooga area. If this actually occurs, most areas of TN should get rain, even far West TN.
I'm still going to wait another day or two to lock down the forecast, but if a good rain is coming, I'm going to broadcast the last of my seed - cereal grains - Wednesday or Thursday.
