Marine Weather and Tides
Version 3.4 |
8/26/2020 The 7 day forecast is taking about 5 seconds to load but it will eventually load. NOAA is still working on it. 8/18/2020 NOAA continues to have trouble. Wind guest will occasionally be left off graphs. I am working with NOAA to resolve the issue. 12/16/2019 NOAA is having trouble with requests that include wind gusts. I am posting graphs without wind gusts until it gets fixed. 10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. |

Area Forecast Discussion National Weather Service Miami FL 308 PM EST Mon Jan 25 2021
SHORT TERM (Rest of Today and Tuesday).
A broad, elongated upper ridge remains entrenched over the western Atlantic Ocean, with South Florida being influenced by the western periphery of a stout surface ridge. The 12Z MFL sounding reveals several stout subsidence inversions, both at 850 and 700 hPa, indicative of strong mid-level ridging influencing the region. Given the influence of aforementioned features, mostly dry weather is expected through at least the next few days, with modest southeast/southerly flow over the region.
With winds forecast to become light and variable overnight and dewpoints to remain in the mid/upper 60s, fog formation will be a forecast concern to monitor through the early morning hours Tuesday. With a strong radiation inversion and light surface flow, patchy fog is possible over interior and western portions of South Florida. Short-range model guidance indicates a strong signal over northwestern Collier County, as well as western portion of Glades and Hendry County. These areas appear to be the most prone to locally dense fog formation. Any fog development should quickly dissipate around sunrise Tuesday.
Temperatures will remain seasonably warm, with a slight warming trend of high temperatures into the lower/mid 80s tomorrow. This should linger through Wednesday, where a cold front is forecast to bring mild relief later in the week.
LONG TERM (Tuesday Night through Monday).
As the sun dawns on the extended period, a shortwave complex will be traversing eastward across the midwest, while high pressure at the surface will be centered over the western Atlantic, holding a boundary stationary over the southeast CONUS. A surface low will eventually develop as the upper level complex continues over the mid- Atlantic states late Wednesday into early Thursday and interacts with the stationary boundary. As the surface low deepens and ejects offshore, the aforementioned boundary should gain southward momentum as an attendant cold front and move across South Florida on Thursday. Favorable dynamics for deep convection will quickly decouple from the boundary and allow for only a feeble line of showers ahead and along the FROPA.
Behind the front, the pressure gradient over the area tightens, while the flow quickly veers out of the NNE. This will result in a few hazards to monitor with each forecast cycle. The first being fire weather concerns, which could become realized on Thursday afternoon as dry air filters into the region coincident with elevated northerly winds in the boundary layer. Additionally, building seas could result in hazardous marine conditions for the local waters, while elevated onshore flow could result in an elevated rip current risk for the east coast beaches of South Florida.
Temperature-wise, with the return of an easterly component, this will help to quickly moderate the airmass, limiting the potential for colder temperatures to stick around. Coldest temperatures will be Thursday night into Friday morning in the mid to upper 40s across the western half of our area and 50s for the eastern portion. Daytime highs will be in the lower-mid 70s Thursday and Friday behind the FROPA and warm back up into the upper 70s, near 80 by the weekend.
AVIATION(18Z TAFS). The influence of high pressure will result in predominately VFR conditions over the region. Intermittent MVFR cigs may develop this afternoon, especially over the Atlantic coast/metro, which has been handled with TEMPO groups for now. Overnight, IFR/LIFR conditions are possible over southwest Florida due to patchy/locally dense fog. Winds generally SE/SSE through the TAF period.
MARINE. Broad high pressure will allow for generally benign boating conditions. Modest SE/SSE flow should persist through mid week. An approaching front later in the week may result in deteriorating marine conditions, as a fetch of NW winds acts to increase surf heights. Swell activity may develop downstream of the front as well, which could persist into the weekend.
FIRE WEATHER. Enhanced fire weather concerns are possible on Thursday behind a late week cold frontal passage. Relative humidity values are forecast to fall below critical thresholds (RHs less than 35%) Thursday afternoon with 20-foot winds near 15 mph.
BEACHES. A high risk for rip currents is in effect for coastal Palm Beach County through Tuesday evening, as modest SE/SSE flow of roughly 15 kts persists through the afternoon. This flow becomes slightly weaker into Broward/Miami-Dade Counties, and hence a moderate risk for rip currents is effect for these areas. An approaching front later this week may result in a high risk for rip currents across the region.
