Area Forecast Discussion National Weather Service Miami FL 341 AM EST Sat Jan 23 2021

SHORT TERM (Today through Sunday).

Surface high pressure will remain situated over South Florida today as a cold front over North Florida moves slowly southward. Light wind, clear skies, and slight warm air advection above the surface are contributing to the development of fog over a good portion of South Florida early this morning. The fog will linger through daybreak, and be locally dense over portions of the Everglades and inland SW Florida. Some of this fog could also affect parts of metro SE Florida although it will be patchy in these areas. The fog should burn off around 9 AM, leading to another day of plentiful sunshine and temperatures approaching or reaching 80F. Gulf coast areas will be slightly cooler this afternoon as a seabreeze from near shore sea surface temperatures in the lower to mid 60s moves inland and should keep air temperatures in the lower to mid 70s at the Gulf beaches.

The cold front will continue to sag southward tonight, but a building mid-level high pressure area from the NW Caribbean to the SE Gulf of Mexico will help shunt the main push behind the front off to our east over the Atlantic. This is also evidenced by the continental high pressure being centered east of Florida's longitude over the eastern United States and western Atlantic. Therefore, we do not expect any significant impacts from the front, and sensible weather effects tonight and Sunday will be primarily from a slight increase in cloudiness area-wide as well as a few showers over northern Palm Beach County and the adjacent Atlantic waters in closest proximity to the front. Areas of fog are again possible tonight, although the increasing clouds raise the uncertainty level as far as coverage and depth of the fog is concerned. With the front remaining to our east, the gradual warming trend will continue, and lows in the mid 50s to lower 60s tonight will lead to highs on Sunday ranging from the mid to upper 70s near the coasts and around Lake Okeechobee to the lower 80s over the interior.

LONG TERM (Sunday Night through Friday).

Generally benign weather conditions across South Florida throughout the extended forecast period, with a mean upper-trough initially located over the western CONUS and broad anticyclonic flow extending downstream across the eastern two-thirds of the CONUS. By mid- week, the upper-trough will translate eastward in association with a progressive mid-level cyclonic perturbation -- supporting surface cyclogenesis over the eastern seaboard and the eventual passage of a cold front through South Florida.

Sunday Night through Wednesday:

A low/mid-level ridge and surface high will be centered over the western Atlantic waters, with west-southwesterly flow aloft. This will support persistent weak positive theta-e advection across South Florida -- leading to a period of above average temperatures. Maximum temperatures should reach the lower 80s on Monday, eventually climbing into the lower/middle 80s area-wide on Tuesday and Wednesday afternoons. Rain chances will remain generally low owing to enhanced dry/stable conditions aloft and minimal forcing for ascent. We will need to monitor fog potential during this time-frame, especially across inland/SW Florida and the Gulf coastal waters -- where persistent boundary layer moisture will interact with the cool Gulf waters.

Thursday and Friday:

By early Thursday, the previously mentioned upper-trough will be evolving eastward across the Ohio Valley -- supporting surface cyclogenesis over the mid-Atlantic states. As the surface low deepens, a trailing cold front will move through South Florida on Thursday, with a band of shallow frontal precipitation moving through the area during the day. Lingering dry/stable conditions aloft will greatly limit the depth and coverage of showers with this cold front. There are some notable differences amongst the global model solutions regarding the frontal passage -- particularly regarding the wind direction behind the front. This will have substantial implications on the minimum temperature forecasts for Friday and Saturday mornings -- though a consensus of models suggest that cold air advection will allow minimum temperatures to fall into the lower 50s to lower 60s each morning. We will continue to monitor trends and adjust these minimum temperatures accordingly.

AVIATION(06Z TAFS).

MVFR and occasional IFR expected in fog/low ceilings over inland and western sections of South Florida, mainly affecting TMB and APF terminals through 14z. Some of these conditions could affect some of the larger east coast airports during the 08z-14z time frame, but much less certainly on this and therefore not included in forecast for now. After 14z, VFR conditions to prevail with westerly wind becoming NE-E 10 kt or less east coast by 18z.

MARINE.

Conditions will be rather benign over the local waters through the middle of next week. The highest wind and seas are expected Sunday night and Monday over the Atlantic waters when SE wind could approach 20 knots along with a northeast swell combining to produce seas of 4-5 ft. Otherwise, winds should remain 15 knots or less and seas less than 4 feet as high pressure dominates the weather pattern through the middle of next week.

BEACHES.

The rip current risk is expected to remain on the low side this weekend, but increase to moderate to perhaps high levels Monday and Tuesday along the Atlantic beaches as SE winds increase along with a long period northeast swell.
