 .SYNOPSIS...
 
 A backdoor front will push into the southeast Georgia waters this
 morning and shift south of the northeast Florida waters later this
 afternoon. A surge of northeasterly winds develop in the wake of the
 front and continues into Wednesday. The onshore flow will keep
 thunderstorm activity mainly on land through the middle of the week.
 The front lifts back northward into the area as remnant inverted
 trough on Thursday resulting in an increase in rain and storm
 chances. As surface high pressure builds to the south, a weak
 southwesterly flow will develop into the Independence Day holiday
 weekend and increase chances for thunderstorms.
