.DISCUSSION...

A weak cold front will move into southeast GA later today and will
drift south into northeast FL Friday and dissipate. A light west wind
will shift to the east by about noon-1 PM as the sea breeze develops
and increases wind speeds. Winds will come around from the southeast
during the late afternoon hours. Humidities will stay above critical
levels. Max dispersions today looks to be around 25-30.

Stronger easterly winds expected Friday with higher dispersion, but
RH values will be well above critical levels.
