The weather during the college football games on Saturday doesn't look too bad. Bring a poncho just in case a shower passes by seeing there is a slight chance during the afternoon and evening hours. Temperatures will be in the lower 80s for the start of the games.
Sunday looks much wetter but computer models still disagree as to where the main wet corridor is going to set up. Models do agree that there will be an upwelling of moisture from the Gulf on Sunday morning through the overnight hours. The Euro and GFS both indicate west, central and southern Alabama getting most of the precipitation. The NAM and RPM models show the wettest weather south and east.

So why so much variability? Well the models are trying to figure out what is going to happen with a couple areas of low pressure. A weaker low pressure system across western Texas that's forecast to track eastward and a stronger closed low pressure system across the Upper Midwest that's forecast to track eastward. Southwesterly flow aloft will allow pieces of energy to lift northward and low pressure at the surface is forecast to develop along the Gulf Coast and track northeastward on Sunday. The exact track and timing of everything coming together in the atmosphere will determine where the heaviest corridor of rain sets up. Some places could easily get 1-3" out of this, especially south Alabama.

Overall, Saturday looks much drier than Sunday. Expect rain on Sunday which could be light and or heavy at times. The heaviest is expected during the afternoon hours and then we'll see some left over drizzle and low clouds through Monday morning. Some localized flooding is possible and we'll be sure to let you know what areas could be under the gun.
