STATUS: IOP Watch

We continue to watch the evolution of the system that will move through northern AL late next week.  Passage of the conditions most supportive of tornadic storms should occur between Thur (24th) noon and Fri (25th) noon.  There are still big questions about the return of humid air from the Gulf of Mexico, and the degree of instability that will develop associated with the moisture return.  Otherwise, it is more likely that strong shear will develop, sufficient for tornadic storms.  A final IOP decision will be made no later than the Monday (21st) daily briefing.
