Marine Weather and Tide Forecast for North Key Largo, FL

LONG TERM
(Friday night through next Wednesday)
Issued at 259 PM EDT Thu Apr 24 2025

Moving into the upcoming weekend, a rather potent northern stream trough will gradually push through the Mid-Atlantic and the Northeast on Saturday into Saturday night before pushing off into the western Atlantic. While this mid level trough will gradually dig southeastward, the trough axis will be offshore and to the east of the region by Sunday. At the surface, South Florida will remain on the southwestern periphery of a large area of high pressure in the western Atlantic. At the same time, a weakening frontal boundary will push through Southeast on Saturday and eventually slowing down and stalling out over the Deep South and Gulf Coast States on Sunday. With the front not making it far enough to the south as high pressure holds strong, this synoptic set up will allow for mainly dry conditions to remain in place across the region on Saturday and Sunday. High temperatures will generally rise into the lower to mid 80s across the east coast to the lower 90s across interior portions of Southwest Florida.

Early next week, the latest global and ensemble guidance suite continues to indicate a moisture increase across the region heading into Monday and Tuesday as what looks like the remnants of the very diffuse frontal boundary tries to push through the region. The forecast becomes a bit uncertain during this time frame as guidance does not have a good handle on the intensity of the boundary (or what is left of it) as it pushes through the region. In any event, with moisture advection taking place along with the diffuse boundary near the region, this could provide just enough lift when combined with the sea breezes to spark off a low chance of showers on Monday and Tuesday during peak diurnal heating. The latest forecast reflects a 20 to 30 percent chance of showers on Monday with some drier air pushing into the region on Tuesday. With the uncertainty still remaining high, these shower chances may linger into Tuesday across a portion of the region depending on the timing and strength of the boundary at that time. This will continue to be monitored as the week progresses. High temperatures will generally remain unchanged as they will rise into the lower to mid 80s across the east coast and into the lower 90s across interior portions of Southwest Florida. the east coast.
