Area Forecast Discussion National Weather Service Miami FL 731 PM EDT Fri Sep 18 2020

. 00z Aviation Update .

Aviation. Mostly VFR conditions will prevail through this cycle. Winds will begin to shift more westerly with time (although stay light . generally below 10kts). A cold front will begin moving southward late in the cycle closer to PBI . so the wind directions begin to transition later Saturday up north. Otherwise, VCs will likely be needed for the Atlantic terminals on Sat Afternoon, but for now the odds are too low to mention.

Prev Discussion. /issued 336 PM EDT Fri Sep 18 2020/

Short Term (Now through Saturday night) . A surface boundary currently resides just north of the forecast area, however, it will gradually move southward before dissipating early in the weekend. This feature along with an Atlantic sea breeze still may cause a few showers and T'storms this afternoon, especially across the Lake region along with Broward and Palm Beach County where the best surface convergence will take shape. CAMs indicate this potential quite well.

Things begin to settle tonight with perhaps a few isolated nocturnal showers over the waters. During the day Saturday, things start out rather quiet, but pick up again during the afternoon hours as the sea breeze tries to march inland across south Florida. Another cold front will be moving southward from north Florida by tomorrow afternoon. Although the front through the short term will reside mainly north of our forecast area, the proximity plus a rich tropical air mass will likely lead to additional afternoon convection on Saturday, albeit isolated to scattered in nature with the best potential again being around the Lake region.

Long Term (Sunday through Friday) . During the second half of the weekend and into early next week, both of the GFS and the ECMWF show a frontal boundary draped across the Florida peninsula and into the Atlantic as an amplifying mid level trough continues to push off the New England coast. This will help the frontal boundary continue to move southward through the region on Sunday night into Monday. At the same time, Hurricane Teddy will be nearing Bermuda during this time frame and it will interact with this frontal boundary well to our northeast in the Atlantic. This interaction however will help to increase the pressure gradient with the area of high pressure off to the north that will be moving in behind the cold front.

This frontal boundary will also help to bring in plenty of deep tropical moisture out ahead of the frontal boundary which will increase the chances of showers and thunderstorms on Sunday into Monday. The strongest storms could contain gusty winds and heavy rainfall which could lead to localized flooding in the urban and low lying areas during this time frame. The latest GFS and the ECMWF show the front clearing South Florida, and a drier air mass begins to push into the region on Tuesday and into the middle of next week. Breezy conditions will continue through the middle of next week due to the strong pressure gradient between the frontal boundary to the south, and the area of high pressure building in from the north. Temperatures during the middle of the week will be slightly below normal due to the frontal passage. Highs will range from the middle to upper 80s across the east coast metro areas to around 90 across the interior sections.

By the end of the week, the latest computer model guidance shows the frontal boundary to the south starting to lift northward again towards the region which could increase the chances of showers and thunderstorms during that time frame. This will continue to be monitored as the week progresses.

Marine . Isolated to scattered convection over the local waters to end the week and to kick off the weekend. A frontal boundary is forecast to approach from the north, increasing rain and thunderstorm chances across the local waters for the weekend. Breezy NE winds behind the frontal boundary will result in building seas and swells in the Atlantic early next week. Small craft advisories will likely be necessary for hazardous marine conditions that develop this weekend into early next week over at least the Atlantic waters.

Aviation . Predominately VFR conditions across the TAF sites through the forecast period. Sea-breezes should be the primary foci for convective initiation/coverage during the period, with VCTS starting around 21Z, lasting until about 00Z. Brief bouts of MVFR/IFR possible near any convection. Winds will predominately be SSW, but sites closer to coast may experience a brief shift to SSE wind direction due to Atlantic sea-breeze. For Gulf coast, winds should be SW becoming WSW

Beach Forecast . A moderate to high risk of rip currents can be expected along the Atlantic coast this evening. A cold front with higher winds and seas will also increase the rip current risk later this weekend and early next week for the Atlantic coast.
