GMZ005 Synopsis For Keys Coastal Waters From Ocean Reef To Dry Tortugas 436 Am Edt Wed Jul 3 2024
Synopsis - High pressure over the western north atlantic will maintain gentle to moderate easterly breezes. Hurricane beryl is well south of the florida keys, and this will remain the case, but breezes will briefly freshen through tonight as beryl makes its closest approach to the keys. As beryl approaches the bay of campeche and the high shifts in the north atlantic, gentle breezes will veer to the southeast over the weekend.

DISCUSSION
Issued at 1030 PM EDT Tue Jul 2 2024
Currently - Ridging dominates the local region through the depth of the troposphere. A surface through lower level ridging stretches westward from the Atlantic into Florida and along the gulf coast. As a result, surface winds are light out of the east.
Meanwhile mid and upper level ridging is aligned over the southeastern United States. This evenings sounding indicated somewhat dry air through the lower levels along with limited low level inhibition. The overall setup is limiting convective potential across the area despite ample CAPE and a PWAT near 2 inches. Conditions are seasonable with temperatures in the mid 80s and dew points in the mid to upper 70s.
Short Term Update - Ridging will continue to dominate the area through the overnight period. The surface ridge across Florida will maintain light east to southeasterly breezes through the night. With that said, Hurricane Beryl will continue to churn west northwestward towards the northwestern Caribbean Sea. This will contribute to a tightening pressure gradient and slowly freshening breezes beginning late tonight. Despite ample CAPE and moisture, the background ridging and low level inhibition will keep convective coverage at bay. Will maintain slight chance pops for the night. Overnight lows will struggle to sneak below the mid 80s, while dew points will remain in the mid to upper 70s.
