.SYNOPSIS...
A frontal boundary pushing slowly southward towards the Georgia
waters will stall this afternoon, with this feature then weakening
on Wednesday. Mainly light showers could impact the northeast
Florida waters through the early morning hours on Tuesday, followed
by additional rounds of showers and thunderstorms impact all of our
local waters this afternoon and evening, with a few strong storms
containing briefly gusty west winds and frequent lightning strikes
possible. Scattered afternoon and evening showers and thunderstorms
will be possible on Wednesday as prevailing winds briefing shift to
northwesterly. Coverage of showers and thunderstorms will then
decrease by Thursday as the frontal boundary dissipates, with only
isolated to widely scattered late afternoon and early evening
activity possible for the near shore waters through Friday as a
prevailing westerly flow continues during the overnight and morning
hours each day. Surface troughing developing over the southeastern
states this weekend could bring scattered afternoon and evening
showers and thunderstorms to our local waters as offshore winds
prevail.
