Currently - A surface ridge stretches west southwestward from a high centered off the southeast Atlantic Coast. This is driving moderate easterly breezes across the Keys and surrounding waters.
Winds tend backed east northeasterly near and north of the island chain, and more east southeasterly over the warmer Florida Straits. Needless to say, this easterly shift in winds has brought in warmer and considerably more moist air with temperatures now in the mid 70s and dew points in the mid to upper 60s. While this evenings sounding did indicate a strong inversion, it has elevated over the past 24 hours and is now above 800 mb. This along with the increasing moisture has allowed for a few weak showers. Some of this activity occasionally affects small portions of the Keys.
Short Term Update - The previously mentioned ridge will remain to our north as the parent high shifts further eastward. This will maintain a moderate easterly synoptic flow across the Keys and surrounding waters. The continued influx of relatively warm and humid air will keep overnight lows above normal in the lower to mid 70s and dew points pushing further upwards in the upper 60s.
Rain chances will remain slight due to the potential for isolated weak showers. With that said, it will be difficult to achieve measurable amounts.
MARINE
Issued at 952 PM EST Fri Dec 8 2023
A ridge across Florida will maintain moderate easterly breezes.
Expect winds to be weaker and backed northeasterly on our gulf and bay side waters compared to modestly stronger east southeasterlies over the Florida Straits.
