At times, winds will slacken and become variable. Expect slightly stronger winds across the Florida Straits. - Temperatures will remain near normal through the end of the week, and slightly above normal this weekend. - Nil rain chances are expected for the next several days as dry air remains entrenched across the Keys. && .AVIATION... (18Z TAFS) Issued at 400 PM EST Wed Feb 11 2026 VFR conditions will prevail at the island terminals. Surface winds will be light out of the east to southeast, backing northeasterly overnight. && .PREV DISCUSSION... Issued at 427 AM EST Wed Feb 11 2026 CIMSS High pressure remains the theme through the end of the week. The high is currently just east of the Bahamas and is beginning to show signs of flattening as a storm system develops off the New England coastline. This ridge is expected to continue flattening over the next few days. Light to gentle breezes continue today becoming light and variable overnight continuing into Thursday. Nil rain chances are expected through the period as moisture remains scarce. In the mid to upper levels, a fairly rigorous shortwave trough is expected to traverse across Florida today/tonight. This will at most result in just some increase in the mid to upper clouds. Temperatures will hover near normal for the next several days along with comfortable humidity. During the periods of light and variable winds, we will need to keep an eye out for potential fog development as the waters surrounding the Chain are quite cool in the 60s. Dew points will begin to further increase into the lower 60s. Latest indications though suggest we might not quite get there to result in the fog formation. Preferably, we would like the dew points to increase even further to the upper 60s to near 70 degrees. As we head through the weekend and into early next week, there may be a brief lull in the quiescent conditions currently being endured. A rather potent upper level low may barrel its way eastward across the North Gulf Coast. This will place the Keys into the warm sector with increasing humidity, rising temperatures, freshening breezes, and increasing moisture. However, numerical and statistical model guidance remain at odds with each other making for a particularly difficult forecast beyond Saturday. Stay tuned as this is still quite far out yet and the details continue to remain murky. && .MARINE... Issued at 427 AM EST Wed Feb 11 2026 There are currently no watches, warnings, or advisories in effect across the Florida Keys coastal waters. From synopsis, high pressure off the Southeast U.S. coastline will slowly meander east out across the Atlantic. This will maintain gentle to moderate breezes across much of the Florida Keys coastal waters through this morning. Thereafter, the high will flatten across Florida, leading to slackening breezes with a couple periods of brief light and variable breezes. Low pressure developing across the ARK-LA- TEX region and high pressure off the Southeast U.S. coastline will result in freshening east to southeast breezes over the weekend. && .KEY WATCHES/WARNINGS/ADVISORIES...
