Warm and Humd; Small Chance of PM Storm

We were fortunate enough to dodge most of the rain yesterday, but we extended our rainy day streak to 11 days. A weak frontal boundary is now located on the Mississippi/Alabama state line, but the air mass change is hardly noticeable. A true cold front stretches from eastern Texas northeast through eastern Missouri. The closed upper low that has been spinning over the Plains states for a few days will open up today and move slowly eastward. The main lift from it will not affect our area until tomorrow, but the true cold front to our west may still generate enough lift for a few isolated showers and thunderstorms this afternoon. Otherwise, we should see more in the way of sunshine today, so temperatures will top out near 85 this afternoon. Any storms that develop this afternoon should dissipate by 10 p.m., which means Bulldog Bash should go off without a hitch. Mostly cloudy skies will remain in place with temperatures dropping to near 71 tomorrow morning.

There are major model differences regarding tomorrow morning's weather. The NAM and GFS suggest that rain will be a problem for the MSU/LSU game. However, the UKMET and regional and global GEM suggest tomorrow morning is relatively dry. With decent dynamics in place and a true frontal boundary pushing toward the area, I would be shocked if there aren't showers and a few thunderstorms that develop tomorrow morning. I suggest to plan for some rain for tailgating and the game. After the front moves through, much drier air will filter into the state and provide some pleasant morning temperatures.
