1029am EST Sat Nov 28 2020

There have been very few changes to the sensible weather elements in the past 24 hours. Gentle northeast to east breezes prevail across the coastal waters and the island chain, a few knots less than yesterday. Patches of stratocumulus and drizzly showers are just south of the Lower Keys, although fewer patches than yesterday. Temperatures are near 80 with dewpoints near 70. The forecast calls for near nil rain chances with highs in the lower 80s. The cold frontal passage for Monday evening remains on track, with very little fanfare until then.

Marine
There are no watches, warnings, or advisories currently in effect for the coastal waters of the Florida Keys. Small Craft Advisories likely will be required Monday night across the Keys as northwest to north breezes freshen behind a cold front. From synopsis, high pressure will linger over the Florida Peninsula through tonight, then sag southward on Sunday. A low pressure system initially over the northwestern Gulf of Mexico will race to the east-northeast Sunday through Monday. A cold front trailing to the southwest of the developing storm system will plow through the coastal waters of the Florida Keys Monday evening. Strong northerly breezes will follow the frontal passage and continue into Tuesday. Fresh to strong northeast to east breezes will persist through at least Wednesday night.
