Marine Weather and Tides
Version 3.4 |
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 . UPDATED National Weather Service Miami FL 958 AM EST Tue Feb 18 2020
Update. No major changes to the forecast through this afternoon/evening. The radar is picking up on a few isolated showers across the Atlantic waters, however, this activity will likely be brief and confined over the offshore marine zones. Otherwise, modified MFL sounding shows a significant cap, which should limit convective development this afternoon.

.12z Aviation Update.
Aviation . Generally VFR with increasing easterly to southeasterly wind after sunrise. A Gulf sea breeze could develop this afternoon and push past APF. Sub-VFR cigs cannot be ruled out, mainly with areas of passing moisture. Fog is possible overnight at APF.
Prev Discussion . /issued 357 AM EST Tue Feb 18 2020/
Short Term (Today through Wednesday) .
Deep-layered high pressure remains over the region with a surface high extending in from the Atlantic and the high aloft reaching in from the Caribbean. This pattern will suppress convection, allowing anything that were to form to remain mainly shallow isolated showers over the next few days. The easterly to southeasterly flow around the Atlantic surface high pressure will keep a warm airmass over the region which will lead to a warm next few days with most of South Florida reaching into the 80s and the potential for upper 80s to around 90 across some portions of inland Southwest Florida where the Gulf sea breeze may not reach.
As the next front begins to push closer, the ridge will elongate over the southern peninsula of Florida into the Gulf. This will allow for lighter wind flow over the peninsula tonight into Wednesday compared to today. Overall, the pattern will remain on the warm side of things but with most stations have their daily records in the upper 80s to around 90 along the east coast, Naples will have to be watched as the records there are mid to upper 80s and we will certainly be in that ballpark.
Long Term (Thursday through Monday) .
Thursday .
The maritime tropical air mass and associated mid/upper-level ridge that has been in place across South Florida will weaken and shift southward throughout the day on Thursday, causing the wind to veer from ESE to WSW across South Florida. As this veering occurs, a slight increase in low-level moisture will allow for the development of isolated to scattered showers across the northern portions of South Florida, including Palm Beach County and the adjacent Atlantic waters. High temperatures will be in the low to mid 80s across the eastern portions of South Florida while the inland areas and Gulf Coast of South Florida will experience mid to upper 80s.
Friday through Monday .
By Friday, a positively tilted 500mb trough will progress southeastward across the eastern CONUS, likely weakening by the time the mid/upper-level trough reaches the Atlantic Seaboard. The differential advection and forcing for ascent associated with this system will likely remain far to the north of the South Florida CWA as it progresses into the western Atlantic waters.
A cold front associated with the aforementioned system will likely approach South Florida from the northwest on Friday, allowing for a rapid tightening of the pressure gradient and surface winds veering to a northerly direction across South Florida. Ensembles and global model solutions suggest a lack of appreciable thermodynamic instability with frontal passage; however, a shallow band of moisture will likely advect across South Florida with the front allowing for the development of scattered showers across the eastern portions of South Florida on Friday into Saturday. In addition, an isolated thunderstorm can't be ruled out over the northern Atlantic waters of South Florida where instability may be maximized.
Global model and ensemble solutions also indicate the development of a surface low pressure off the South Carolina/Georgia coastline by Friday morning. This feature should quickly progress into the Atlantic waters but may allow for an additional tightening of the pressure gradient, leading to an increase in wind speeds mainly across the Atlantic waters of South Florida. Will have to monitor the development of this feature as it will likely influence the evolution of the aforementioned cold front and associated weather across the region.
A continental polar air mass behind the aforementioned cold front will shift southeastward before settling over the Tennessee Valley late Friday into early Saturday. South Florida will be located along the southern periphery of this surface high pressure as it weakens and shifts eastward throughout the weekend. This will allow for the pressure gradient to remain tightened across South Florida through Sunday, bringing breezy northeasterly winds. High temperatures will be in the 70s across South Florida this weekend before slightly increasing into the upper 70s to low 80s by Monday.
Marine .
Benign seas with a persistent easterly to southeasterly wind that could reach cautionary levels at times this week. The next front will approach the region later this week, with increasing winds and seas that could create hazardous marine conditions by the weekend. Mariners should continue to monitor the forecast through the week for the latest.
Beach Forecast .
A persistent easterly to southeasterly flow could allow for an elevated rip current risk to remain along the Atlantic beaches through Wednesday. A wind shift ahead of the next cold front later in the week may lead to a brief improvement in rip current risk, particularly along the Miami-Dade and Broward Atlantic beaches.
