Area Forecast Discussion National Weather Service Miami FL 217 AM EST Sat Nov 28 2020

Short Term (Today-Sunday).

High pressure over the state will continue to push southward through Sunday, keeping light to moderate E/SE flow at the sfc and generally benign boating conditions across the coastal waters. A cold front is expected to approach the area on Monday and bring an increase in showers and possibly a few thunderstorms, along with increasing west- northwesterly winds. The northerly component may bring building seas near the Gulf stream by late Monday and Tuesday.

Sfc analysis show weakening high pressure over the central portions of the Florida peninsula and the west Atlantic, which will remain in control of the weather pattern today. Meanwhile, a Low/front system stretches across the Florida panhandle and into the northeast Gulf waters, which is expected to keep slowly migrating southward on Sunday.

Some moisture intrusion started yesterday with a few showers passing through portions of Miami-Dade at times. 00z MFL sounding showed a little higher PWATs around 1.1 inches, but with a solid 800 mb inversion still in place restricting significant vertical development. Thus, in general, benign weather should again prevail today, with a few passing shallow showers this afternoon and evening, mainly moving inland from the Atlantic waters.

For Sunday, WPC shows the aforementioned Low/front pushing into central Florida, which further weakens the mid level ridging over SoFlo. If this scenario doesn't changes significantly in the next couple of model runs, Sunday should again enjoy fairly benign weather conditions with maybe a little better cloud coverage as the ridge weakens and more moisture ahead of the front filters into the area. For now, will keep POPs in the 20% range at best to cover the chances for passing showers each afternoon. A stronger/deeper trough/front complex is expected to move into the deep SE CONUS and northern Florida beginning Sunday night, but its potential impacts on SoFlo are not anticipated until Monday attm. However, any change in the timing of arrival of this front will require adjusting the forecast philosophy for Sunday afternoon. So, upcoming model runs for the next 24-48 hours will be critical in terms of having a clearer picture of the potential time of arrival of this FROPA event.

Temperatures remain around normals with afternoon highs in the low 80s and morning lows in the mid 60s to low 70s.

Long Term.

Sunday Night through Friday Night .

A weak ridge aloft will continue to keep benign and quiet conditions across South Florida through Sunday Night. This ridge of high pressure aloft, albeit weak, will keep a weak frontal boundary to the north of our region late this weekend. This weak frontal boundary will stall over Central Florida, before moving northwards as a warm front on Sunday Night/Monday Morning. A surface low will develop along the warm front boundary in the Gulf of Mexico, and accelerate to the northeast. The trajectory and speed of this surface low, has implications on the potential weather impacts we may see across South Florida. If the surface low takes a faster and further north trajectory, the track would place the best dynamics for greater impacts to the north of our area. If the surface low takes a slower and more southerly trajectory, the track would place the best dynamics a little closer to our area, and could potentially see a greater impact.There are still differences in the exact placement of the low between the GFS and the European models at this time, with that being said, it will be important to continue watching the trends with the surface low and the passage of the associated cold front.

Behind this front, a cool and dry air mass will move into South Florida on Monday Night/Tuesday Morning. Although the cold front will pass through during this time, the coldest night will be on Wednesday when the cold air advection will be the strongest. There are some notable differences between the GFS and the European models during this time frame. The latest European model has temperatures in the 40s across the interior with temperatures near 50 along the east and west coast of South Florida. The latest GFS model is a little warmer with lows in the upper 40s west of the lake, 50s across the rest of the interior and the west coast, and temperatures near 60 degrees along the east coast. It will be important to continue to monitor changes in the forecast as we move closer in time to this period.

After the passage of the front and subsequent cold air advection, a warming trend will begin on Thursday as a high pressure aloft progresses to the northeast. This will shift the overall flow to the east and then southeast, which should allow for increased moisture across the area. The GFS and the European models both show a second front progressing eastwards across the Gulf of Mexico on Thursday with a potential passage across South Florida late week/ next weekend. It is too early to speculate on the passage of this front, but this may be something to monitor in future discussions.

Marine. High pressure over the state will continue to push southward through Sunday, keeping light to moderate E/SE flow at the sfc and generally benign boating conditions across the coastal waters. A cold front is expected to approach the area on Monday and bring an increase in showers and possibly a few thunderstorms, along with increasing west- northwesterly winds. The northerly component may bring building seas near the Gulf stream by late Monday and Tuesday.

Aviation. VFR prevails during the next 24 hours at all terminals with high pressure remaining across. Winds remain ENE in the 5-10kt range, except APF with winds veering WSW in the afternoon as sea breeze moves inland.

Beach Forecast. Moderate easterly winds and a remnant swell will keep rip current potential at the moderate level through this evening at all beaches of Palm Beach County. Afterward, risk remains low through mid week when increasing NE/E winds will bring back an elevated risk for the Atlantic beaches.
