Synopsis..High pressure over the eastern united states will extend south to the local waters through the weekend. A large, powerful low pressure system will meander off the new england coast today through Saturday before moving to the east later this weekend. This low pressure area will send large north to northeast swells to the atlantic waters beginning late this afternoon and continuing through Friday night, with a second round of large swells Sunday and Monday. Small craft should exercise extreme caution especially around jetties and inlets. High pressure will move off the southeast united states coast by Monday, continuing the pattern of light easterly winds.
Gulf stream hazards..SEas building to 7 to 10 feet in north northeast swell off the palm beach county coast late this afternoon and continuing through Friday.

Area Forecast Discussion National Weather Service Miami FL 357 AM EDT Thu Apr 2 2020

Short Term (Today through Friday Night).

The cold front which passed through South Florida yesterday is currently well to our south across the eastern Bahamas and Cuba. Surface high pressure centered over the Great Lakes region will extend south all the way to Florida through Friday, as a powerful low pressure system spins just off the New England coast. The position of these two systems will result in a dry N-NE wind flow across South Florida. Daytime skies should be mostly sunny today and Friday, and accompanied by temperatures close to seasonal normals (a big change from the persistent above normal temperatures of the past few weeks). This translates to low temperatures in the 50s interior and 60s near both coasts, and highs ranging from near 80 along the coasts to the mid to upper 80s over the far interior sections. Humidity values will be low, therefore no significant heat impacts are expected. Light wind during the night and morning hours will freshen some near both coasts with the afternoon sea breezes.

Long Term (Saturday through Thursday).

Fairly warm and dry conditions are forecast through the next week with a gradual warming trend in place. Easterly surface flow is expected through much of the period as high pressure slides southward along the Atlantic Seaboard while a surface cyclone remains kind of stuck offshore the Mid Atlantic states for a few days. The GFS is showing a bit of unsettled weather over the Gulf Saturday night into Sunday as a small shortwave rotates across the northern Gulf, but it seems to dissipate the disturbance before it reaches South Florida as the shortwave outpaces it over the eastern Gulf. The ECMWF doesn't show this at all and has been more consistently showing a drier trend for the weekend as opposed to the GFS which originally was very wet for the weekend. Therefore, confidence is much higher with the ECMWF solution for now, and therefore no meaningful rainfall is in the forecast.

A cold front pushing across the Southeast CONUS Tuesday into Wednesday should stall well to our north but will still shove the area of surface high pressure further south over the Florida Straits/Bahamas. This will bring the surface winds around to more southwesterly Wednesday into Thursday, which will in turn cause temperatures across the eastern portion of the area to rise even further. With the gradual post-frontal warming trend and change in the winds, high temperatures will rise into the upper 80s and low/mid 90s once again by Wednesday and Thursday.

Marine. The strong low pressure system off the New England coast will send large N-NE swells as high as 6-7 ft down to the local Atlantic waters of South Florida beginning this afternoon and lasting through Friday night. These swells will be more pronounced off the Palm Beach County coast, with smaller but still significant swell down the coast. NWPS is indicating a temporary break from the large swells Saturday and Saturday night, but then followed by a second swell field Sunday into early next week. Therefore, hazardous marine conditions can be expected over the Atlantic Gulf Stream waters off Palm Beach County and a Small Craft Advisory will be issued starting at 2 PM this afternoon through 2 AM Saturday. Small Craft Exercise Caution will be needed for the waters off Broward/Miami-Dade counties, with Gulf of Mexico seas subsiding from 4 ft today to 2 ft or less by Friday.

Beach Forecast. The arriving swells will lead to a high risk of rip currents at the Palm Beach County beaches this afternoon, then at least a moderate risk down to the Broward and Miami-Dade beaches Friday and through the weekend. Surf conditions will become increasingly rough at the Palm Beach coast this evening through Friday, and will have to be monitored for possible high surf advisory conditions.

Fire Weather. With the continental air mass in place over the next few days, lowest relative humidity values are expected to be below 35 percent over most of the interior this afternoon and again on Friday. Although light wind will mitigate the fire weather threat, enhanced fire weather conditions are still expected today and Friday due to the low relative humidity values and dry fuels.
