Synopsis.. High pressure over the eastern u.s will extend south to the local waters through the weekend. A powerful low pressure system will meander off the new england coast through Saturday before moving to the east later this weekend. This low pressure area will generate large north to northeast swells across our atlantic waters 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 coast by Monday continuing the pattern of light easterly winds.

Area Forecast Discussion . UPDATED National Weather Service Miami FL 819 PM EDT Thu Apr 2 2020

Update. Forecast looks to be right on track this evening. A very benign weather pattern has set up across the region. Still expecting a cool overnight for the interior regions. Outside of that, Atlantic marine conditions will remain adverse over the Palm Beach Adjacent waters with the increasing northeasterly swells. Rip current potential will continue to increase tonight for Broward and Miami- Dade beaches as well so these headlines may need to be extended in the near future.

Prev Discussion. /issued 736 PM EDT Thu Apr 2 2020/

.00z Aviation Update.

Aviation . Easterly winds and VFR conditions can be expected through this TAF cycle. The only issue will be the wind transitions along the Gulf breeze for APF on Friday afternoon.

Prev Discussion . /issued 331 PM EDT Thu Apr 2 2020/

Short Term (Rest of Today and Tonight) . High pressure dominating across the region promoting stable and dry conditions for the remainder of this afternoon and throughout the overnight hours. Mostly clear skies, with a light sprinkling of fair weather cumulus clouds, and near seasonal temperatures today and tonight with no rain expected. Sea breezes along both coasts will diminish early this evening and continue to lighten overnight.

With drier air over the region, MFL's 02/12Z sounding measured a PW of 0.70 inches, minimum RH's are at or below 35 percent across South FL. Due to the drier conditions, enhanced fire weather conditions are expected for this rest of this afternoon. More on that in the "Fire Weather" section below .

Overnight lows are forecast to drop into the mid to upper 60s along the east coast with mid to upper 50s elsewhere.

Long Term (Friday through Wednesday) . A warm and dry weather pattern will continue across South Florida through the end of the week and into the first part of the upcoming weekend as an area of high pressure slides southward off of the eastern seaboard and into the Atlantic. There are some differences still remaining in the latest computer model guidance in regards to the pattern for the end of the weekend and into early next week. The GFS is still showing a shortwave rotating across the northern Gulf and into the Florida peninsula and brings an increase in moisture to the region along with it as well. The ECMWF is now also showing the shortwave moving into the area, however, it is not as robust as the GFS is. The latest forecast for Sunday does introduce a slight chance of showers across Palm Beach County and the Atlantic waters. This will continued to be monitored as the rest of the week progresses.

Beyond that, an area of high pressure in the Gulf of Mexico will try to build back into the region during the middle of the week. The ECMWF shows this ridge building in farther to the north and stronger as well, while the GFS shows a weaker ridge not making it as far north which would allow for another shortwave to pass just off to the north of our region. The current forecast trends more towards the ECMWF with the drier solution for the middle of the week. This will continue to be watched as the week progresses. In any event, high temperatures will be on a moderating trend and highs by the middle of the week will range from the upper 80s across the east coast metro areas to the lower 90s across the interior sections.

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 is in effect from now 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.

Aviation . VFR conditions will prevail at all terminals during the next 24 hours. Seabreeze dominant flow through around 00z, then returning to light N-NE to even VRB overnight. Dry air will keep clouds to a minimum with seabreeze dominant flow returning once again Friday afternoon.

Beach Forecast . The arriving swells will lead to a High Risk of rip currents for the Palm beaches this afternoon with a Moderate Risk for the Broward and Miami-Dade beaches. 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. Elevated rip current potential for all South Florida Atlantic beaches will persist into at least the weekend.

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 for the rest of this afternoon and Friday due to the low relative humidity values and dry fuels.

Preliminary Point Temps/PoPs. West Palm Beach 64 80 65 82 / 0 0 0 0 Fort Lauderdale 68 79 69 81 / 0 0 0 0 Miami 67 81 68 82 / 0 0 0 0 Naples 62 83 66 83 / 0 0 0 0

MFL WATCHES/WARNINGS/ADVISORIES. FL . High Rip Current Risk through late Friday night for FLZ168.

AM . Small Craft Advisory until 2 AM EDT Saturday for AMZ650-670.

GM . None.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
