Welcome to Multimedia Impact Weather Briefing. This briefing will focus on the
potential for a wintry mix of rain/snow for portions of Central Alabama today.
An upper level disturbance will move through the Southeast. Temperatures across the area
will be near or just above freezing across Central Alabama. Precipitation will spread
across the area from west to east, beginning during the morning hours. There will be a
possibility of a mixture of rain and snow near and along the Interstate 85 corridor,
in the shaded blue area seen here. Further to the north, a light snow and sleet mix is
possible along and near the Interstate 20 corridor, seen in the white shaded area above.
There continues to be a large amount of uncertainty regarding this system and temperatures at
and just above the surface. Currently, temperatures are expected to be above freezing, but a difference
in a couple degrees could result in either all rain or all snow. Models have slowed down
over the last runs and we will slow it down as well. Looks like the best chances will
be after 9am for the south and 11 am for
the north.
Accumulations remain quite uncertain. Again, temperatures are expected to be at or just
above freezing through the day as the precipitation occurs. If the snow falls hard enough, there
could be minor accumulations. The highlighted area reflects the best area which could see
minor accumulations but this area could shift slightly. At this time, half an inch of accumulation
is the most accumulation we expect, however with such a low confidence we can not issue
an advisory at this time. Keep this in mind we are a good ten degrees warmer right now
than the last event. This event with be precipitation amount driven, while the last event was more
of a flash freeze scenario. Temperatures after sunset will drop quickly to below freezing
and you need to monitor closely travel conditions, especially if there is any moisture left around.
As troublesome as this event is, we are going to have to monitor a system in the extended.
Both longer range models indicate a low will develop along the southern coast of Texas
and slide northeast toward southern Alabama. One model keeps the low along the coast and
just brings it inland, where the second long range model takes it much further north. A
north track would keep the area all rain, while a southern track would increase the
chances of snow on the backside. This will be a system we will need to keep an eye over
the next few but feel as though there is enough agreement with the models to at least begin
the discussion. Of course this could also change with the next model run, so stay aware.
