Welcome to the Multimedia Impact Briefing for Central Alabama. We will be discussing
the potential for severe weather Thursday evening through Friday morning.
The Storm Prediction Center has placed a large portion of the United States, and nearly all
of Central Alabama, in a Slight Risk for severe weather on Thursday due to an upper level
disturbance and a strong cold front at the surface moving over the region.
Looking at the severe weather probabilities for Thursday from SPC, note that locations
with the red area have a 30% chance of seeing severe weather within 25 miles. This enhanced
area includes much of the northern and western portions of Central Alabama. Locations in
the yellow area have a 15% chance of seeing severe weather within 25 miles.
Zooming in to just Central Alabama, a strong cold front will enter western Tennessee and
northern Mississippi during the afternoon on Thursday. A line of strong to severe storms
will be located just ahead of the front, moving eastward with time. As the cold front moves
over the state Thursday evening, probably after 6 PM, there is a chance for severe thunderstorms
across all of Central Alabama. At this time the primary threat appears to be damaging
straight-line winds in excess of 60 mph along the line of thunderstorms. But, there will
be enough wind shear and instability in the atmosphere for the possibility of isolated
tornadoes as well. The highest threat area for damaging winds and isolated tornadoes
is highlighted in red. The front should be pushing out of our southeast counties early
Friday morning. Again, all of Central Alabama will have a risk of seeing severe weather
from Thursday evening northwest through Friday morning across the southeast.
The timing and severe threats are subject to change as we get closer to the event, so
stay tuned for the latest information. During rapidly evolving weather situations, please
