Issued at 1030 PM EDT Mon Sep 1 2025 A broad very early season mid latitude trough remains parked over the eastern United States. The lower level trough reaches down into South Florida and central Gulf. An associated weak surface low is stewing off the Central Florida Atlantic Coast. The result of this is a continuation of the days long wet weather pattern across the Keys. This evenings sounding indicated considerable deep layered moisture with ample CAPE. Convection near the island chain has died down over the past couple of hours. However, new round of showers have begun developing on our Gulf and Bay side waters. No notable changes are expected to the weather pattern across the broader area. The broad band of increased moisture and confluent flow will remain across our area while the low remains nearly stationary off the Florida Coast. As a result, further rounds of shower and thunderstorm activity are expected. Away from rain cooling, overnight lows will be broadly in the lower 80s with dew points in the mid to upper 70s. && .MARINE...
