GMZ005 Synopsis For Keys Coastal Waters From Ocean Reef To Dry Tortugas 1029 Pm Edt Fri May 16 2025
Synopsis - A dry pattern defined by a distant high pressure system in the central atlantic and lack of a close high over the conus will lead to breezes shifting from light to moderate breezes for the next few days. In the absence of nearby strong pressure systems, breezes will peak and lull through Tuesday. NEar nil shower chances will persist until Wednesday as an increase in moisture allows for possible showers and isolated Thunderstorms.

DISCUSSION
Issued at 928 PM EDT Fri May 16 2025
The western Flank of an elongated Atlantic ridge stretching westward through South Florida and into the Gulf is generating gentle to moderate east to southeasterly breezes on the Keys and surrounding waters this evening. Deep layered ridging remains fully in control with sharp upper ridging stretching northeastward across Florida and the lower to mid level centered over the Florida Peninsula.
This evenings sounding indicated 1.26 inches of precipitable water, which is about the 25th percentile. A couple of inhibition layers and limited moisture is evident between 875 and 975 mb.
Consequently, shower activity has been absent, as has stratocumulus. Conditions are rather warm with temperatures still in the lower 80s with dew points edging upwards into the mid 70s.
Deep layered ridging will remain in control of our area overnight.
The Atlantic surface ridge will maintain gentle east to southeasterly breezes across the Keys. Rain chances will remain nil under mostly clear skies. Warm conditions will continue with overnight lows struggling to push into the upper 70s and dew points meandering in the lower to mid 70s.
