.NEAR TERM /Now Through Sunday/...The upper low that brought
today's weather has wobbled northeast to over the Midwest by
00z/7pm, with another vort lobe swinging around the southwest 
side of the low at this time. A cold front associated with this 
upper system has pushed to the Mississippi/Alabama state line, and
is expected to move just southeast of the marine portion of the 
forecast area by 12z/7am Saturday morning, then stall. As the 
second vort lobe swings around the upper low later tonight through
Saturday, isentropic upglide on the northwest side of the stalled
front sets up, bringing showers and to areas closer to the front,
thunderstorms. The majority of the precipitation is expected to 
remain south of the coast, though. The cold front will move south 
Saturday night into Sunday as the vort lobe swings north on the 
leading edge of the upper low, taking any residual precipitation 
with. Cooler air will overspread the forecast area behind the 
front, dropping temperatures tonight into the upper 40s to near 50
northwest of I-65, low to mid 50s southeast (with this area 
seeing less cold air influx). Temperatures Saturday will top out 
in the upper 60s to around 70 as the cool northerly flow 
continues. Saturday night will see temperatures dropping into the 
low to mid 40s across the majority of the forecast area. Sunday 
will see temperatures rebound as surface high pressure moves over 
the Southeast, with low to mid 70s expected.

With the surface flow shifting to offshore tonight, the High Risk
of rip currents will drop as the onshore swell eases. Am also
expected the High Surf to ease tonight with the relaxing of the
onshore flow.
