Synopsis.. Scattered showers and a few Thunderstorms will be possible today as a frontal boundary over the lake region slowly pushes northward. The small craft advisory for the atlantic has been extended due to lingering wave action in the gulf stream, but conditions should gradually improve over the next day or so. A cold front will push through the area tomorrow with winds becoming northwesterly in its wake. However, hazardous boating conditions are not expected in the wake of this front. Another, stronger front should push through the area around midweek next week.
Gulf stream hazards..SEas 7 to 9 feet today. The approximate location of the west wall of the gulf stream as of dec 12, 2019 at 1200 utc... 13 nautical miles east of fowey rocks. 19 nautical miles east northeast of port everglades. 18 nautical miles east northeast of lake worth. 16 nautical miles east northeast of jupiter inlet.

Area Forecast Discussion National Weather Service Miami FL 540 AM EST Fri Dec 13 2019

Aviation. Generally VFR conditions are expected through the period with passing showers expected across the East Coast TAF sites. Brief periods of MVFR to IFR conditions will be possible with passing showers. A few thunderstorms will also be possible right along the coast and over the Atlantic, with the greatest potential probably near KPBI. Winds gradually become southwesterly through the period as a cold front approaches the region.

Prev Discussion. /issued 358 AM EST Fri Dec 13 2019/

Discussion .

Short Term (Today Through Saturday Night) . Scattered showers and a few thunderstorms will be possible across portions of the area today as a diffuse frontal boundary over the Lake Region pushes northward as a warm front. Best coverage of showers/storms is forecast over the Atlantic and across the eastern half of the Peninsula, particularly Palm Beach county with the southwest steering flow this afternoon. A few storms out over the Atlantic could be fairly strong this afternoon and evening, but southwesterly steering flow should keep them offshore. Easterly winds to start the day will become more southerly to south- southwesterly through the day today as an area of surface low pressure pushes northeastward across North Florida and up the Southeast CONUS coast. This low pressure system will drag a cold front across South Florida on Saturday, with only weak showers expected along it as the mid and upper-level support has largely ejected off to the northeast by the time the front enters South Florida. Northwesterly to northerly winds are expected in the wake of the front with cooler and drier air filtering in over the area. Low temperatures Saturday night are forecast to drop into the low 50s west of the Lake to near 60 along the East Coast.

Long Term . (Sunday-Thursday) . Models depict a broad high pressure system expanding across the region in the wake of the FROPA, bringing a brief cool down from late Sunday into Monday. The colder air will result from modest cold air advection from prevailing NNE flow, which will keep morning lows on Monday in the upper 50s to mid 60s inland, and in the mid-upper 60s over the metro areas.

The high gradually migrates eastward into the Atlantic seaboard, with its SSW periphery moving over SoFlo and veering winds to a more SE flow. This will bring back some low level moisture from the Caribbean and modify the airmass over the area, which combined with daytime heating will push POPs back into the higher-end scattered 45-55% chance of rain by Tuesday afternoon. Expect temperatures to also climb back on Tuesday afternoon into the low to mid 80s.

Global models remain in fair agreement regarding the next FROPA across the FL peninsula, associated with a deepening trough/low complex across the eastern states. Motion of this front continues to slow down with latest solutions bringing it across the northern half of Florida late Tuesday into early Wednesday morning. It will also contribute in the increasing POPSs/Wx for the Tuesday- Wednesday timeframe ahead of the approaching boundary.

A few storms are possible Tuesday afternoon, but with the best dynamic lifting/support remaining well to the north of SoFlo, will keep chances of thunderstorms at a minimum attm and wait for upcoming model guidance before going any higher.

More cold air advection establishes behind the FROPA through the end of the work week with overnight temperatures a few degrees colder than the previous nights. Expect upper 40s to low 50s around Lake Okeechobee, and in the low 60s along the east coast Thursday and Friday morning. But this scenario could change significantly if the models are either too slow or too fast with the FROPA.

Marine . Hazardous marine conditions continue for the Atlantic waters today with seas remaining elevated in the Gulf Stream through this evening. Passing showers and a few thunderstorms will be possible across all waters today and tonight as a stalled front over the Lake Region pushes northward. A cold front will push through the area tomorrow, with northwesterly winds in its wake. Hazardous boating conditions are not expected in the wake of this front. However, another stronger front will push through around midweek next week and may create hazardous marine conditions at that time.

Beaches . A high risk of rip currents is forecast for the Atlantic beaches today as lingering swell continues to affect the coast. Rough surf will also be possible for the Palm Beaches. Rip currents should improve some this weekend before elevating again early next week with breezy east flow.
