This whole wedge thing is a bit weird. Normally you would need high pressure on the east coast pushing dry air down the east side of the Appalachians into northern GA and eastern Alabama, but here we have actually a low on the east coast and wedge keeps pushing west. Even the hrrr is showing the wedge strengthening. This is now showing quite the warm front in B'ham metro area...all while Tds are building just south of Bham. Hopefully a cell doesn't ride the warm front into Bham, but I could see that being a problem early in the afternoon.
