SPC introduced a 15% area along the I-35 corridor on Friday. Not sure we’ll get enough moisture return for the threat to extend as far north as they’ve depicted it. The Euro is a bit more optimistic than the GFS is with it.
Tuesday’s ceiling over the Mississippi River Valley has been inching upward. Slightly more amplified system with sufficient moisture return will probably yield a decent threat over Ark/West Tenn/NW Mississippi. This could inch up into West KY and SE MO as well. Support quickly lifts out and winds veer over a narrowing warm sector further East into AL/GA and Eastern TN.
I just saw this come across facebook. I think with most people having phones that weather sirens are becoming quickly outdated. We should not be reliant on them anyway. We cannot hear them well indoors.

Going along with JayF's post above this one, the WSFA mets (Montgomery, Al.) posted this morning, "Storms late tonight, can't rule out a brief tornado." So the 'T' word is being bantered about here & there. Will there be enough instability in the Central Alabama atmosphere for a tornado later tonight?
Wow. The frontal passage in Oklahoma has opened to door to very strong winds. Gusts this afternoon up to 55mph. Apparently they have something out there (midwest) called a 'Jeep Wind Warning'. Don't think we have that particular warning here in Alabama, & surrounding states. Crazy!
