Sixpack meteorologist here, and any other mets on here can chime in. Looking to be a big trough swinging in on Egg Bowl day and the timing of this trough will be a big weather player. This is a very stout upper trough and will swing into the area but the timing lately has been an issue as models have slowed down on the time this approaches the area. The model cuts off the upper trough into what is called a cutoff low and that sticks around for a few days. Anyway, the big question is will the trough and approaching frontal system be here at gametime Saturday. The models had been showing it approaching in the MS Delta with heavy rainfall at 12pm and over Starkville with heavy rain at 6pm. Now the winds aloft are very strong and if we could have some heating and any instability wise, I would worry about some strong severe weather. Met friends here, showed SRH of 800 for Columbus with southeast winds..To give you an idea, SRH or storm relative helicity on April 27th was about or just over 1000 so its significant..However, it looks to be only forced convection or storms and no instability wise so tornado threat looks like null. Still I will keep an eye on it as any instability could make the Egg Bowl forecast very interesting for severe weather..My main concern is the timing of possible heavy rainfall and hopefully the slower GFS is a trend that the model takes...If not we could be in for a soggy Egg Bowl and missed field goals =/...
