 .SYNOPSIS...A frontal boundary will stall across central Florida
 through Wednesday. This will keep winds light and variable during
 the day with brief nocturnal surges off the mainland in the
 evening and early portions of the overnight. Conditions will
 remain favorable for a cloud line to develop over, or across the
 waters adjacent to the Florida Keys on Wednesday. This may
 support the development of waterspouts. High pressure gradually
 builds back across the area Thursday with peaks and lulls
 resuming.
