.SYNOPSIS...

Weak low pressure situated about 150 miles to the east-southeast
of Jacksonville, Florida this morning may organize into a Tropical
Depression later this morning as it progresses west- northwest.
Bands of gusty showers and embedded thunderstorms will increase in
frequency and intensity with this activity continuing through
late this afternoon before diminishing in coverage as this weak
low pressure center progresses inland. Meanwhile, strong high
pressure centered north of Bermuda will gradually weaken as it
settles southward this weekend. Small Craft Advisory conditions
will continue throughout our local waters today, followed by winds
and seas diminishing to Caution levels on late night and then
below Caution criteria on Saturday. Rounds of showers and
thunderstorms will continue to develop over our local waters this
weekend and into next week as prevailing winds become southerly
ahead of a weakening surface trough that will settle over the
southeastern states through midweek.
