Synopsis for Keys coastal waters from Ocean Reef to Dry Tortugas
424 PM EDT Mon May 19 2025
.SYNOPSIS...A dry pattern defined by a distant high pressure
system in the central North Atlantic and lack of other major
synoptic influences will lead to breezes shifting from light to
moderate over the next few days. Winds will oscillate throughout
the day peaking overnight and lulling with daytime heating through
Tuesday. Near nil shower chances will persist through Wednesday.
An approaching, decaying front on Thursday will lead to an
increase in rain and thunder chances as well as a period of light
and variable winds.
