It is a very tropical airmass across Alabama tonight, thanks to days of a deep moisture plume emanating from the eastern Pacific Ocean and funneling straight up into the Deep South.
Heavy rain is increasing tonight in two bands.
It looks almost exactly like the morning and overnight runs of the GFS and our in house RPM model.
Western sections will continue to see heavy rain until the cold front arrives later tonight and drier air starts to move in from the west.
The eastern band shows increasing rainfall activity over Southwest Alabama…this heavy rain will continue moving northeast over areas just south of Tuscaloosa and Birmingham into East Central Alabama. If it persists, we could eventually see flooding problems…
