**No afternoon map discussion video today**
Will keep this fairly short...
Surface based CAPE values are running around 1500 over much of Alabama... the air is fairly unstable, but we need to get into the mid 80s to really make the storms explode. Hopefully clouds will keep us in the low 80s for the rest of the afternoon.
However, current instability is sufficient for strong to severe storms later today and tonight as an upper trough approaches. We also note an MCV (mesoscale convective vortex) in radar returns over the southwest part of Mississippi; that feature seems to be rolling in our direction. That feature might enhance storm development over the central and southern part of Alabama.
Bottom line is that we still expect strong to severe storms over Alabama from around 3:00 until midnight. Large hail and strong winds will be the main threat, but an isolated tornado or two is not out of the question.
The weekend still looks dry; clearing tomorrow, sunny on Sunday.
We will keep the blog updated... J.B. Elliott will be arriving here in the office shortly. We will do our best to keep a fresh supply of Pop Tarts and Buffalo Rock for him!
