Fresh northerly breezes will persist in the wake of the recent
cold front passage. A brief lull in winds is possible this
afternoon but would quickly increase after sunset. Moisture will
linger across the region maintaining above normal rain chances.
However, chances for wetting rains are low, especially for the
Lower Keys. Cloudy skies, and at times breezy conditions will
persist through tonight, along with gradually decreasing rain
chances.
