Good Morning Mike. Well tommorrow again still looks good. I wonder if it will hold together as it moves East past B'ham area toward my neck of the woods, and what the approx. time frame will be for my area. I will be away from my desk for most of the day, but will check back.. My folks have a Dr. appt in B'ham so I told them to take there cell so they can call me for updates.
Hi Michelle. I think it will hold together. It is impossible to pinpoint what will happen where as you know. But all of N&C AL looks to be under the gun somewhere between 11 and 9.
I am interested to see if the SPC goes moderate or high risk with this one.
