Issued at 953 PM EDT Fri Jul 18 2025 Robust surface ridging stretches across the Florida Peninsula this evening, resulting in gentle to moderate easterly breezes across the Keys. Winds have tended slightly stronger across the Florida Straits. This evenings sounding indicated precipitable water quite high at 2.27 inches and above the 90th percentile. However, CAPE below 700 mb is quite limited with some very low level inhibition. Consequently, shower activity has been limited and thunderstorms have been very limited. Ridging will remain dominant through the overnight period. This will maintain gentle to moderate easterly breezes across the Keys. Rain chances will also be slight as incoming drier lower levels will likely offset the usual nocturnally enhanced confluence. Expect overnight lows to be in the lower to mid 80s with dew points likely slipping into the mid 70s. && .MARINE...
