.PREVIOUS Issued at 430am EST Fri Feb 6 2026 Winter will continue across the Keys through the weekend. In the wake of yesterdays front, surface high pressure will move in, though, the center of this ridge will remain across the western Gulf. Therefore, breezes are expected to remain northwesterly for an extended period of time from today into the weekend. Another piece of energy will drop southeastward across the eastern United States over the weekend. This may result in a reinforcing weak frontal boundary to push through the Keys sometime Saturday evening or overnight. High pressure will then dominate the pattern for the the remainder of the weekend through much of next week. Moisture remains scarce resulting in near nil rain chances through the extended. Breezes will modestly slacken today and tonight with gentle to moderate breezes prevailing through the period along the Island Chain. However, with the weak frontal passage potentially Saturday evening/night, breezes may increase back to moderate to fresh for a time. Temperatures will slowly moderate each day through the extended, though, we wont fully get back to average till perhaps the middle to latter half of next week. Humidity will also slowly creep up each day, especially mid next week onward, though still remaining quite comfortable.

Marine
Issued at 1003am EST Fri Feb 6 2026 Generally moderate breezes will continue this morning in the wake of a recent cold frontal passage. As the front continues to push away from the Florida Keys today, breezes will somewhat slacken, although marine conditions will remain hazardous. An area of high pressure will build across the Mid- Atlantic over the weekend, supporting moderate northwest breezes. As the high slides southeastward late Sunday through early next week, breezes will slacken and clock around to the northeast.
