.SYNOPSIS...

A slow moving cold front over northeast FL waters will slowly
drift southward through tonight. The frontal boundary will then

the Florida peninsula by midweek, resulting in a decreasing
coverage of showers and thunderstorms for our area on Tuesday and
Wednesday. Breezy northeasterly winds will may then develop by
Wednesday and Thursday as high pressure builds over the Ohio
Valley and coastal troughing develops across the northeast Florida
waters, where chances for showers and thunderstorms will increase
later this week.
