Area Forecast Discussion National Weather Service Miami FL 558 AM EST Wed Feb 19 2020

Aviation. Generally VFR with some sub-VFR low cigs or fog possible around APF this morning. Light flow out of the east to southeast except for the potential of a Gulf sea breeze at APF again today. Some showers could develop from east to west through the day, particularly along the interior in the afternoon.

Prev Discussion. /issued 356 AM EST Wed Feb 19 2020/

Short Term (Today through Thursday) .

A mid to upper level area of high pressure centered around Cuba and the northern Caribbean Sea will keep convection fairly shallow today. Southeasterly flow around a surface high in the Atlantic will allow the warm, moist airmass over the region to persist and another warm day is forecast with the potential for another record at Naples to be on the line. Morning showers from the Atlantic could push into the east coast metro before the convective focus shifts westward for the afternoon with the State Road 29 corridor being a target for showers later in the day. A Gulf sea breeze is expected to develop and advance which could contribute to a few more showers in this area.

The frontal boundary over the southeastern United States will eventually gain a push forward as a mid-level longwave trough pushes through the central United States on Tuesday. The mid-level high centered to our south will eventually cede to the frontal boundary with Thursday serving as a pattern transition day. The surface flow remains with a southerly component ahead of the front on Thursday, so the warm and moist airmass will remain with temperatures rising into the 80s across the area. Ahead of the mid-level longwave trough, a shortwave trough will push off the south Atlantic coast of the United States, helping to spur a surface low off Georgia and the Carolinas late on Thursday.

Long Term (Friday through Wednesday) .

Friday through Sunday .

By late Thursday evening into overnight Friday, a mid/upper-level positively tilted trough will progress southeastward across the eastern CONUS, leading to cyclogenesis off the South Carolina/Georgia coastline. As the surface low forms and rapidly deepens, winds across South Florida will veer from the E/SE to the N/NW and begin to increase in magnitude. Boundary layer moisture will remain in place across South Florida as the veering occurs, leading to the development of isolated to scattered showers across the eastern portions of South Florida.

The aforementioned surface low pressure is forecast to quickly progress northeastward with the main upper-level steering flow as it drags a frontal boundary across South Florida throughout the day on Friday. As this occurs, winds will continue to veer from a N/NW direction to a northerly direction in conjunction with a rapidly tightening pressure gradient across South Florida. Wind gusts are currently forecast to be at or above 30 mph for most areas of South Florida on Friday afternoon, with higher gusts over the Atlantic waters of South Florida. This will introduce hazardous marine conditions (see Marine section below). A relatively shallow band of moisture is forecast to advect across the region with the frontal boundary, allowing for the development of isolated to scattered showers. Shower coverage is forecast to be greatest over the eastern portions of South Florida and the adjacent Atlantic waters. High temperatures on Friday are forecast to be in the 70s across most areas of South Florida.

By Saturday, winds across South Florida will veer from a northerly direction to a northeasterly direction, allowing for moisture to advect from the Atlantic waters across the eastern portions of South Florida. This will allow for the continuation of isolated to scattered showers across the eastern portions of South Florida in addition to the potential for an isolated thunderstorm over the northern Atlantic waters of South Florida where thermodynamic instability may be maximized. Saturday will be another breezy day with wind gusts forecast to be near 25 mph throughout the day across most of South Florida. Higher gusts can be expected across the Atlantic and Gulf waters of South Florida leading to a continuation of hazardous marine conditions. Minimum temperatures on Saturday morning will be in the low 50s near Lake Okeechobee and inland South Florida, while the eastern areas will experience the low 60s. High temperatures on Saturday will be slightly cooler than Friday, in the low 70s across much of South Florida.

The pressure gradient will relax slightly on Sunday leading to a decrease in wind speeds across South Florida as surface high pressure settles over the Tennessee Valley. Easterly surface winds will allow for isolated showers to move onshore along the Atlantic coastline of South Florida, especially early in the day. The Atlantic and Gulf waters of South Florida will still see wind gusts of 20 to 25 mph throughout the day on Sunday leading to the continuation of hazardous marine conditions.

The aforementioned surface high pressure will weaken and shift eastward into the western Atlantic waters as a deepening low pressure system traverses the central CONUS on Sunday.

Early next week .

The aforementioned low pressure system is forecast to lift northeastward, keeping the dynamic forcing for ascent and appreciable thermodynamic instability well to the north of the South Florida CWA. Surface winds will veer to a southeasterly direction through this period, allowing for a slight uptick in boundary layer moisture. Therefore, a slight chance of showers may exist on Tuesday and Wednesday across the northern portions of South Florida ahead of an approaching frontal boundary. High temperatures will be back in the 80s during this period.

Marine .

Cautionary conditions remain possible, particularly with easterly surges, over the next day or so. A front will push across the region late in the week with strong winds, elevated seas, and swell in its wake. Hazardous marine conditions will develop by the weekend with the potential for at least Small Craft Advisory. Some portions of the Atlantic could see winds approaching Gale force with seas reaching 10 to 15 feet as swell from a low off the Carolinas pushes into the local waters this weekend. The hazardous conditions could linger into early next week in the Atlantic waters off South Florida.

Beach Forecast .

An elevated rip current risk will remain today along the Atlantic beaches. There is some improvement expected for Thursday before the rip current risk begins to creep upward on Friday into the weekend. Increasing swell and building northeasterly winds will create a high risk of rip currents for much of the weekend along with the potential for high surf and beach erosion along the Atlantic beaches. These hazardous beach conditions could linger into early next week as well.

Another concern is the potential for coastal flooding with high tide due to the new moon this weekend. The northeasterly to easterly wind, persistent swell, and high seas will contribute to the potential for higher-than-normal tides which could create minor coastal impacts for at least this weekend.
