Area Forecast Discussion
National Weather Service Key West FL
1042pm EST Monday Mar 1 2021

Currently - Deep layered ridging remains entrenched across the area with the surface and lower level ridges displaced east of Florida and ridging into the Gulf of Mexico. This is resulting in light to gentle east to southeasterly breezes across the Keys and surrounding waters. Stable conditions prevail with multiple subsidence inversions, the lowest of which is near 950 mb. While no shower activity has been detected by local radars, there are few to scattered stratocumulus seen in satellite, primarily over the Florida Straits. Temperatures are slowly falling through the upper 70s with dew points near 70.

Short Term Update
Ridging will continue to dominate the area through the overnight hours. This will keep stable conditions with essentially no rain chances. Winds will remain light to gentle out of the east to southeast. This will keep overnight lows in the mid 70s with dew points lingering near or slightly above 70. No update is planned for the local forecast.

Marine
An Atlantic ridge extending across Florida will maintain light to gentle east to southeasterly breezes on Keys waters overnight. Have only minor changes made in the evening marine update.
