Issued at 1030 PM EDT Mon May 6 2024 Currently - An Atlantic high continues to pivot out into the Atlantic while holding on to a ridge that stretches west across Florida and the Gulf of Mexico. This is maintaining moderate easterly breezes across the Keys. This easterly flow is resulting in a continued slow moderation. Temperatures remain generally near 80 with dew points up in the lower 70s. The Keys is within the broad descending branch of a low amplitude upper trough over the Atlantic. As a result, lower to mid level ridging is situated well to our west. This evenings sounding indicated essentially no inhibition with precipitable water ticking upwards to around 1.66 inches. Despite this, a lack of lower level forcing and some drier layers in the lower levels have prevented any shower activity near the island chain. A few showers have been able to percolate over the distant southeastern Florida Straits and over the gulf waters west of Fort Myers. Short Term Update - The surface high will continue to push further out into the Atlantic. However, an associated ridge will remain planted westward across Florida and the gulf. This will keep moderate easterly breezes across the Keys. Forecast soundings indicate that some inhibition may develop, but up around 850 mb. Meanwhile, moisture through the lowest levels is expected to nudge upwards. All this along with continued moderate breezes and the usual nocturnal peak justifies holding onto dime pops through the overnight period. Expect temperatures to only fall a degree or three from current readings and overnight lows will settle in the upper 70s with dew points remaining in the lower 70s. && .MARINE...

(00Z TAFS) Issued at 1030 PM EDT Mon May 6 2024 VFR conditions will prevail at the island terminals overnight.
