Issued at 1000 PM EDT Sun Jun 16 2024 Currently - A surface ridge running parallel to the Atlantic Coast, and along the northern Gulf Coast, in concert with falling pressure over Central America has resulted in moderate to fresh easterly breezes across the Keys and surrounding waters this evening. Deep layered ridging is planted across the broader area. Despite ample moisture through much of the column, as indicated in this evenings sounding, there is a fat layer of drier air below 700 mb with a nose of inhibition based at a low 960 mb. As a result, there has been a near complete lack of convective activity within the forecast area. The steady flow has maintained warm and rather humid conditions with temperatures remaining in the mid 80s with dew points in the mid 70s. Short Term Update - Robust surface ridging will remain across the southeast through the overnight period. This along with the Central American gyre continuing to deepen will keep moderate to fresh mostly easterly breezes across the Keys. Deep layered ridging will remain in control. That said, forecast soundings suggest that the lower levels will moisten and destabilize a bit through the night. This may open the door for a few showers and thunderstorms. Will maintain slight chance of showers and thunderstorms. The healthy flow will keep overnight lows broadly in the lower 80s with dew points remaining in the mid to upper 70s. && .MARINE...
