. Gale Warning for the Atlantic, Gale Watch for the Gulf . . Small Craft Advisories for Lake Okeechobee and Biscayne Bay . . Wind and Coastal Flood Advisories for coastal SE Florida .

Short Term (Today through Tuesday). South Florida remains in a very unique pattern with bookending tropical systems to the west and to the east. Tropical Storm Beta lingers over the northwestern Gulf of Mexico off the Texas coast and Hurricane Teddy is southeast of Bermuda on its way north- northwestward. A frontal boundary located off the eastern seaboard of North America extends across the peninsula of Florida into the Gulf of Mexico. Some perturbations along this frontal boundary have caused clusters of convection to develop over the last day or so which have evolved into meso-lows with strong gusty winds, torrential rainfall, and heightened lightning activity.

As the frontal boundary passes through the region today, the tightening gradient will allow wind speeds to pick up with gusts to gale expected over at least the Atlantic waters and the immediate coast. Accordingly, a Wind Advisory is now in effect through tonight for coastal Palm Beach, Broward, and Miami-Dade. If the wind speed forecast ends up being too low due to an underestimation of the gradient, this advisory may need to be expanded westward. Convection today could tap into the 35+ kt winds aloft and produce some strong wind gusts today.

Rain chances will diminish through the evening and overnight hours from north to south as the boundary exits from the area into the Keys and Straits. Drier air will bring some lower 70s over Southwest Florida and the Lake Okeechobee region with the northeasterly flow keeping a slightly warmer and more moist airmass along the east coast. Shallow showers cannot be ruled out through Tuesday due to this moisture, though thunderstorms are not expected due to the lack of deeper moisture and instability.

Long Term (Wednesday through Monday). Wednesday and Thursday .

Medium-range model guidance depicts a relatively dry air mass remaining in place across South Florida on Wednesday (dewpoints in the lower 70s), with the aforementioned quasi-stationary surface boundary located to the south of the peninsula. The pressure gradient will remain slightly enhanced across the region, allowing for breezy easterly surface flow and the maintenance of adequate boundary layer moisture. This should allow for isolated fast-moving showers to develop and spread westward, though any activity that develops should remain fairly shallow due to very dry mid-level air and poor lapse rates/weak static instability.

The air mass across South Florida will begin to modify on Thursday as mid-level winds veer to a southerly direction, and surface flow turns southeasterly. This will allow for deep-layer moistening to begin, resulting in PWs climbing back to near 2.0 inches. Once again, poor mid-level lapse rates should limit overall convective intensity, though 20 knots of veering boundary layer flow could foster enhanced convective momentum transfer and gusty surface winds with showers and storms. Maximum temperatures will be slightly below average, with middle to upper 80s common across South Florida.

Friday through the weekend .

Extended model guidance is beginning to come into better agreement with a progressive (yet amplifying) shortwave trough traversing the central and eastern CONUS late in the week. Present indications are that a poleward mass/moisture flux could allow for the aforementioned weak quasi-stationary boundary to lift northward across South Florida, advecting a moisture-rich air mass across the southern peninsula into this weekend. While there is currently plenty of uncertainty with the evolution of the long-range pattern (owing to many sub-synoptic scale interactions), a dramatic uptick in convection can't be ruled out across South Florida as we move into the weekend. Forecast soundings continue to depict deep-layer saturation (owing to the poleward moisture flux) across South Florida, suggesting that locally heavy rainfall could become a concern. Depending on the evolution of the surface boundary and rich tropical moisture, South Florida could experience multiple days of fairly enhanced convective coverage -- when rainfall accumulations could become a concern across vulnerable low-lying metro areas.

Marine. Increasing gradient flow behind the frontal boundary and Atlantic swell from Hurricane Teddy will create hazardous marine conditions through the next few days. Frequent gusts to gale are expected over the Atlantic waters through tonight with frequent gusts to gale possible over the Gulf waters later today through tonight. With that, the Small Craft Advisories for the Atlantic waters have been upgraded to a Gale Warning and the Small Craft Advisories for the Gulf waters have been converted to a Gale Watch for this afternoon, evening, and early overnight. Will allow the next shift to monitor in case conditions dictate that additional adjustments are necessary for the remainder of the waters under SCA or if the Gale Watch has to be upgraded to a Gale Warning for the Gulf waters. Hazardous conditions will begin to diminish in the Gulf faster than the Atlantic overnight thanks to swell that will remain in the Atlantic for a good portion of the week.

Beach Forecast. Astronomically high tides are beginning to decrease as we pull away from the New Moon, but the persistent northeasterly wind flow and swell are still producing elevated high tide cycles along the Atlantic coast in the 1.7 feet MHHW neighborhood. With that being near the point where moderate flooding impacts are possible, a Coastal Flood Advisory is in effect for today with a Coastal Flood Statement remaining in effect for tomorrow.

The risk of rip currents along the Atlantic beaches will remain elevated through the week and potentially into the weekend. Accordingly, the rip current statement has been extended through Friday for the Palm Beaches and Thursday for the Atlantic beaches of Broward and Miami-Dade.

High surf along the Palm Beaches is expected to persist into at least Wednesday with beach erosion also a concern.

Prev Discussion. /issued 147 AM EDT Mon Sep 21 2020/

Aviation . Bouts of sub-VFR conditions and gusty winds through much of the period as a frontal boundary passes through the region. Vsbys and cigs should improve late afternoon into the evening as showers and storms shift south. Winds will pick up with gusts of 25 to 30 kts possible.
