LONG TERM [Friday through Tuesday]...
A very progressive pattern is on tap with two low pressure
systems expected to impact the area during the extended period.
Deep layer ridging with dry conditions on Friday will quickly
weaken and move east making way for the approach and passage of a
cold front over the weekend. The front will be weakening as it
pushes across our FA as the deepest moisture and best upper
support staying well to our north. Prospects for rain over the
weekend will be in the lower end chance category. Models now show
a clear frontal passage all the way down the peninsula Sunday
night with dry conditions locally through Monday before another
opportunity for rain arrives Tuesday as a deep low pressure system
is forecast to develop over the lower Mississippi Valley. The
surface low is forecast to track eastward from northern
Mississippi Monday night to just off the North Carolina coast by
00z Wednesday. Meanwhile, with the strong upper low forecast to be
positioned over south Georgia Tuesday, we would expect overcast,
breezy and much colder conditions. Would like to see more run to
run consistency before trending the forecast in that direction.
For now we see temperatures at or above seasonal levels through
the extended period.
