Area Forecast Discussion National Weather Service Key West FL 1027 PM EDT Wed Jul 28 2021
DISCUSSION. Current air temperatures across the Florida Keys are in the mid 80s, with dewpoint temperatures in the mid 70s, and heat indices in the lower 90s. Winds are very light out of the east. Skies are mostly clear, with latest radar and satellite data showing only a few showers across the entire service area. An upper-level composite analysis shows a deep layer mean anticyclone centered over the central United States, and another smaller anticyclone centered over the western North Atlantic, with a trough along the eastern seaboard. The Florida Keys are in a region of rather nondescript flow with light winds in the lower and middle troposphere amidst weak vertical motions. A small, but well- defined upper- tropospheric cold-core cyclone was drifting westward over the Straits of Florida. However, the system was shallow, with any forcing for ascent seemingly confined mainly to the upper troposphere. Data from the Key West evening radiosonde balloon indicated a typical conditionally unstable atmosphere with some low-level convective inhibition. Low levels were slightly richer in moisture than 24 hours ago. Boundary-layer flow was weak and slightly difluent.
Current forecasts of isolated showers/storms overnight are on track, and no updates are planned.
MARINE. No watches, warnings, or advisories are in effect for Florida Keys coastal waters zones. A ridge axis will straddle the Florida Keys island chain through Thursday, resulting in light to gentle generally east to southeast breezes. The ridge will slide northward Thursday night through the weekend bringing the axis over south-central Florida, resulting in breezes freshening slightly. Rain and thunder chances will remain near-to or slightly below normal for the rest of the week and into the weekend.
AVIATION. VFR conditions will prevail at both the Key West and Marathon terminals overnight and into tomorrow morning. Surface winds will be light, generally from and easterly direction, but could become variable at times.
CLIMATE. On this day in 1916, the daily record rainfall of 7.14" was recorded. This is also the wettest day ever recorded in July. Rainfall records in Key West date back to 1871.
