 .SYNOPSIS...The combination of an expansive eastern United States
 surface high, a surface trough in the central Gulf will keep
 breezes generally moderate over the next couple of days.
 Uncertainty remains high, and periods of higher breezes will be
 possible, especially due the continued above normal shower and
 thunderstorm activity expected across the area. Rain chances
 should trend downwards towards normal this weekend as drier air
 moves in and breezes trend slightly downward.
