Area Forecast Discussion
National Weather Service Key West FL
1023am EDT Monday September 27 2021

There have been multiple instances so far this morning where members of the Keys community have commented: definitely feels more comfortable outside. Dewpoints are down to near 70, and given our many month adjustment to dewpoints in the mid to upper 70s, the lower humidity is noticeable. The 12Z KKEY RAOB (Radiosonde Observation or Upper-Air Observation) sampled PW near 1.5", which is around the 25th percentile for the date. MFL sampled less than an inch, which is a daily minimum record. Given the northeasterly steering, the drier airmass over South Florida will work into the Keys this afternoon, along with dewpoints a few ticks lower. The forecast calls for near nil rain chances with highs near 90. No changes needed or planned.

Marine
There are no watches, warnings, or advisories currently in effect for the coastal waters of the Florida Keys. High pressure anchored over the southeastern United States will result in an extended period of moderate northeast to east breezes. Breezes will freshen further Thursday night into Friday.
