Temperatures will remain well above average, with highs in the mid 90's all weekend long. Down in the tropics, odds are now at 60% for tropical development in the southern Gulf of Mexico (more below). 

Today & Tonight: The heat engine will continue today. Highs will be near 96 degrees under mostly sunny skies. This will make things quite unpleasant for some football. According to the LSU Kickoff Weather Index, a feels-like temperature near 100 degrees at game time will make this one of the top three hottest on record in Tiger Stadium. The last game this hot, and likely the hottest on record, came against Tennessee in 2005 as the teams kicked off to a heat index of 103 degrees. Skies will be mostly clear tonight, with lows near 72 degrees. Patchy fog cannot be ruled out.

Up Next: Although Sunday will be the first day of fall, it will not feel like it. That will be the case next week as well. Days will feature a mix of sun and clouds with highs in the low to mid 90s and feels-like temperatures near 100 degrees. Nights will be muggy and slightly uncomfortable with lows in the low 70s. Small rain chances are introduced by Monday and Tuesday, but the vast majority will stay dry. 

The forecast gets a little tricky by the middle and end of the week. The two key features will be an approaching cold front to the north and a tropical disturbance to the south. The rather low confidence forecast at this time calls for a status quo of temperatures through Wednesday with perhaps some added moisture for showers and a slight downturn in temperatures by the end of next week. Expect some changes to the forecast and stick with the Storm Station for those updates.

The Tropics: A broad area of low pressure is likely to form by the early to middle part of next week over the northwestern Caribbean Sea and the adjacent portions of Central America. Thereafter, gradual development of this system is possible, and a tropical depression could form as the system moves slowly to the north or northwest over the northwestern Caribbean Sea and across the Gulf of Mexico through the end of next week. 

Strong upper-level winds continue to keep showers and thunderstorms displaced away from the center of an area of low pressure (the remnants of Gordon) located over one thousand miles southwest of the Azores. Significant development of this system is not expected while it moves slowly northwestward over the central subtropical Atlantic during the next couple of days.

An area of low pressure located about 700 miles northeast of the northern Leeward Islands is producing some disorganized shower and thunderstorm activity. Environmental conditions do not appear conducive for significant development of this system during the next couple of days while it drifts northwestward and then northward at about 5 mph over the central or western subtropical Atlantic.

A tropical wave is expected to move westward from the coast of Africa on Sunday or Monday. Gradual development of this system is possible next week as it moves west-northwestward over the eastern and central tropical Atlantic.
