AMZ600 Synopsis For Jupiter Inlet To Ocean Reef Fl Out To 60 Nm And For East Cape Sable To Bonita Beach Fl Out To 60 Nm- 433 Pm Edt Sat Oct 24 2020
Synopsis.. Showers and Thunderstorms will be on the increase through Sunday across the local waters. The strongest activity may locally increase winds and seas as well as produce cloud-to-water lightning. Additionally, pressure gradient will begin to tighten between a developing tropical system in the western caribbean and a building surface high across the western atlantic. This will likely cause elevated seas for the atlantic. Gulf waters may also begin to become elevated as the tropical system is expected to move into the gulf of mexico by early next week generating at least a modest swell.
Gulf stream hazards..SEas of 4 to 6 feet. Gusty winds and lightning possible. The approximate location of the west wall of the gulf stream as of oct 24, 2020 at 1200 utc... 12 nautical miles east of fowey rocks. 17 nautical miles east of port everglades. 13 nautical miles east southeast of lake worth. 13 nautical miles east southeast of jupiter inlet.

Short Term (Rest of Today through Sunday).

High pressure centered over the Mid-Atlantic, Hurricane Epsilon in the Atlantic north of Bermuda, and a broad area of low pressure in the western Caribbean are the major synoptic features near the region. As the plume of tropical moisture arrives after traversing the Florida Keys and Straits, the convective activity and coverage will increase. Storm motion is complex as the majority of convection is located in east-west oriented bands spiraling northward to northwestward. The showers and any embedded storms that develop with these bands will be capable of producing torrential rainfall which could exacerbate existing saturated areas. There could also be isolated cells which develop between bands and create a concern for some gusty winds as well.

As the moisture overspreads the region today into tonight from southeast to northwest, coverage will increase. Overnight, the loss of diurnal heating may help keep shower efficiency at bay over some inland areas but areas along the Atlantic and Gulf coasts could be targets for slightly heightened levels of activity due to the coastal influences on any convection. The coverage will again surge up early Sunday morning as an additional round of moisture surges in and the mid-levels come into play with some potential shortwave troughs ahead of a larger trough in the northeastern Gulf. The way that these features may come into phase create a concern for low predictability of timing of the excessive rainfall threat. The Flood Watch currently is in effect through at least tomorrow evening and may require extension into Monday if the event continues into tomorrow night.

Temperatures will struggle to reach the mid 80s on Sunday with the high cloud cover and more widespread precipitation. On the converse, the overnight cooling will be stifled by these factors and the ample moisture. Raised the wind forecast a bit above guidance to reflect a bit of a gradient flow with the potential low developing to our southwest and the high shifting into the Atlantic.

Long Term (Sunday night through Saturday).

Deep tropical moisture will remain in place on Sunday night and into the day on Monday as the tropical disturbance in the Carribean continues to slowly move off towards the northwest. Quick moving and gusty showers will continue during this time frame with periods of heavy rainfall possible. The heavy rainfall could result in the potential for additional flooding concerns through Monday as the area will remain saturated from heavy rainfall earlier in the week as well as over the past several days. High temperatures on Monday will generally remain in the mid 80s across the east coast to the upper 80s across the interior sections.

As Tuesday and the middle of the week approaches, the GFS and the ECMWF are both in agreement with a mid level ridge of high pressure building over the region. This will allow for a drier air mass to move into South Florida which will suppress shower and thunderstorm activity during this time frame. There will only be a slight chance of showers mainly over the interior sections during the afternoon and evening hours. With the dry air mass in place, this will help to keep any shower that does develop brief. High temperatures through the middle of the week will generally range from the 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 mid level ridge slowly moving into the western Atlantic. Both of the GFS and the ECMWF also show an area of low pressure moving into the Carolinas and up into the mid Atlantic. The cold front associated with this system will move through the Southeastern portion of the country and into the Florida Peninsula. This could cause the chances of showers and thunderstorms to increase across the region towards the end of the week and into next weekend. This will continue to be monitored as the week progresses.

Marine. Abundant moisture remains over the region and continue to support scattered to numerous showers and thunderstorms through the rest of the weekend and possibly into early next week. Mariners should remain well informed about weather conditions over the coastal waters, especially with the ongoing uncertainty regarding the potential development of a low pressure system over the western Caribbean or the southeastern Gulf of Mexico.

Aviation. Shower and thunderstorm chances will continue to increase this afternoon and this evening and will remain in place on Sunday. East to southeasterly winds will continue across all terminals through tonight and into Sunday as well. There could be periods of MVFR or even IFR in the showers and thunderstorms that move through the region.

Beach Forecast. Subsiding swell from Hurricane Epsilon and long-lived easterly wind flow maintain an elevated rip current risk through the weekend along the Atlantic beaches of South Florida. Cannot rule out building Atlantic surf to 5-6 feet, particularly along the Palm Beaches. Depending on the progress of the broad area of low pressure over the western Caribbean, there could be impacts to local beaches if this system were to develop and create higher surf and allow an elevated risk of rip currents to develop along the Gulf beaches or persist along the Atlantic beaches.

Hydrology.

Tropical moisture will continue to stream into the region from the western Caribbean as a tropical low continues to develop east of the Yucatan Peninsula. A weak surface boundary will begin to stall across the region through early next week. Along and south of this feature, showers and T'storms will increase in coverage tonight and especially on Sunday. With soils remaining saturated across the Atlantic metro and very efficient convective rainfall, will continue the Flood Watch through at least Sunday afternoon. Rainfall amounts of 2-4 inches will be common across the Atlantic metro with locally higher values possible (especially across the far southern sections of the metro).
