...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FOR NORTH
FLORIDA...

...SUMMARY...
A few instances of hail and locally strong wind gusts are possible
across northern Florida through Sunday morning.

...01Z Update...
Thunderstorms with occasionally stronger cores have persisted from
the northern Gulf across northern Florida for much of the afternoon
and evening. Storms have been quite weak across northern Florida
this afternoon/evening and ascent is expected to move east of this
region in the next few hours. Therefore, expect any severe threat
with this activity to be minimal. A relative lull in stronger storm
activity is anticipated for much of the overnight period, but storm
coverage may increase after 08Z as a weak shortwave, currently off
the southeast Louisiana coast approaches the Florida Peninsula.
Storms which form along and near the surface front, currently
between Ocala and Jacksonville, will likely remain mostly
sub-severe, but occasional strong storms may be possible given
moderate forecast instability around 1500 J/kg MLCAPE and strong
effective shear around 50 to 60 knots.
