.SYNOPSIS...

Atlantic high pressure will build westward across the Florida 
peninsula today. Only isolated to widely scattered thunderstorms are
expected to develop late this afternoon and evening, mainly for the 
waters north of St. Augustine. The axis of Atlantic high pressure 
will then shift southward on Sunday and Monday as a frontal boundary
pushes into the southeastern states, with this feature stalling just
north of the Georgia waters by midweek. Southwest to westerly winds 
will prevail from Sunday through midweek, with evening wind surges 
likely increasing speeds to Caution levels. Only isolated to widely 
scattered afternoon and evening thunderstorms are expected on Sunday
and Monday, with coverage potentially increasing towards midweek as 
the frontal boundary approaches from the north.
