Area Forecast Discussion . UPDATED National Weather Service Miami FL 732 PM EST Sun Mar 7 2021

UPDATE. High pressure will continue to build into the Southeastern United States tonight allowing for the breezy to windy flow to become more northeast tonight. This will allow for the ongoing isolated showers to work toward the east coast metro areas tonight and move into the east coast metro areas before dissipating. Therefore, isolated POPs have been added for the east coast metro areas for tonight.

Rest of the forecast looks good at this time and no other changes are planned at this time.

AVIATION. The wind flow will remain north to northeast tonight with speeds of 10 to 15 knots over all of the TAF sites. There could be a few showers tonight over the east coast TAF sites, but the coverage will be few to put into the east coast TAF sites at this time. The ceiling and vis will also remain in VFR conditions, but could fall down into MVFR conditions with any shower passage tonight.

PREV DISCUSSION. (Issued 250 PM EST Sun Mar 7 2021)

.Wind Advisory Atlantic Coast Tonight.

SHORT TERM .

Tonight and Monday .

A mid to upper level trough over the Eastern United States will continue to move eastward into the Atlantic Waters, as high pressure builds into the Southeastern United States. This will allow keep the pressure gradient tight over South Florida, as the breezy to windy northerly flow becomes more northeasterly. The weather will also remain dry through Monday.

Lows tonight will be in the 50s over most areas, except around 60 east coast metro areas and mid to upper 40s west of Lake Okeechobee. Highs on Monday will be in the 70s over most areas except around 70 east coast metro areas.

LONG TERM .

Monday Night through Sunday

High pressure at the surface and aloft will remain the primary weather influencer through the long term period, outside of a weak shortwave trough pushing through the region during the early portion of the week with little fanfare. Surface high pressure initially centered over the Southeast States will shift east to locate over the central North Atlantic Ocean late in the period while gradually weakening. Until that time our position along the southern periphery of the low-level ridge will keep the pressure gradient robust resulting in breezy winds and hazardous beach and marine conditions. While generally dry weather is anticipated with high pressure in control enough low-level moisture persists for periodic low-end shower chances at times for the Atlantic waters and east coast. However predictability is low at this juncture so left rain chances below mentionable levels as suggested by the blended model guidance. Temperatures should remain seasonal with a gradual warming trend towards late week. Highs should be in the 70s through Wednesday with 80s spreading from west to east across the area towards the weekend. Lows should be mostly in the 60s to around 70, with some upper 50s possible for the Northern Everglades/Lake Okeechobee region through mid-week.

AVIATION(18Z TAFS) .

Winds are the primary story out there. Waiting for FLL and MIA to transition to NNE from NNW this morning . seems to be a bit slower than forecast guidance suggested earlier, but it appears the transition is in progress. Gusts up to 20-25knots will be possible through the afternoon and into the evening. Although the stronger gusts will subside a bit overnight, gusty conditions may continue and perhaps increase again by mid-morning on Monday. Otherwise, VFR expected through the cycle.

MARINE .

Hazardous marine conditions will continue as high pressure continues to build into the region. As the high moves in, the pressure gradient will continue to tighten and remain tight through early week. A SCA is in effect for all coastal waters, but the worst conditions will reside over the Atlantic ocean and gulf stream where swell and wind wave heights build to near 10 feet at times. Some slow improvement is expected, first with the Gulf, Biscayne Bay, and Lake Okeechobee waters by Tuesday with perhaps gradual improvement by midweek for the Atlantic.

BEACHES .

With a strong northeasterly flow and increasing northeast swell, a high risk of rip currents can be expected to continue into the early part of this workweek along the Atlantic coast.
