Issued at 1030 PM EST Wed Dec 4 2024 Currently - A weakening surface ridge is being shoved southward down the Florida Peninsula by a sprawling mid latitude low further off to the north. This is resulting in slackening local breezes out of the northeast to east. Cooler waters to our north and a cooling mainland is resulting in lighter winds backed north in areas close to South Florida. Cool post cold front conditions continue, but some moderation has taken place. Temperatures are up a couple of degrees from 24 hours ago and dew points are up well over 10 degrees in some locations. Despite this, stable conditions are evident in recent soundings with strong inhibition based below 850 mb and a lack of moisture. Some stratocumulus has been able to invade portions of the Upper Keys. On balance however, most of the island chain is seeing only thin cirrus. Short Term Update - The previously mentioned surface ridge will continue to be squeezed southward into Central Florida by morning. This along with bay waters broadly in the mid 60s and mainland cooling will keep winds along the Keys light out and loosely out of the northeast. Expect winds to be backed more north in the Upper Keys. Temperature will be range in the mid 60s with dew points picking up a degree or two in the upper 50s. Rain chances will be nil with skies ranging from mostly clear to partly cloudy. && .MARINE... Issued at 1030 PM EST Wed Dec 4 2024 A weakening surface high is being pressed southward into the Florida Peninsula tonight. This will result in winds continuing to trend downwards and generally fall gentle to moderate out of the northeast to east. In the short term, waters more proximate to South Florida will tend weaker and backed due to the relatively cool bay and gulf side waters along with a cooling mainland. Only minor adjustments made in the evening marine update. && .AVIATION... (00Z TAFS) Issued at 1030 PM EST Wed Dec 4 2024 VFR conditions will prevail at the island terminals. Surface winds will be light out of the northeast. && .KEY WATCHES/WARNINGS/ADVISORIES... FL...None.
