Area Forecast Discussion National Weather Service Miami FL 110 PM EDT Fri Sep 17 2021

AVIATION(18Z TAFS). Scattered showers and thunderstorms will continue to develop throughout the afternoon and into the evening hours. This could create periods of MVFR or IFR at the terminals during this time frame. South to southeast winds across the east coast terminals will become light and variable this evening. At KAPF, west southwesterly winds will continue throughout the afternoon before becoming light and variable as well during the evening hours.

PREV DISCUSSION. (Issued 944 AM EDT Fri Sep 17 2021)

UPDATE . An area of high pressure will continue to build into the region from the western Atlantic today. This will allow for the light south to southwesterly flow to continue. Some slightly drier air has worked into the area as noted from the 12Z KMFL Sounding. The PWAT values came in around 1.85 inches this morning. Convection will once again be sea breeze driven this afternoon, however, with poor lapse rates and rather warm 500 mb temperatures (-5C), the potential for strong thunderstorm development will be rather low. With the slow storm motion remaining in place, the potential for localized flooding will be the main concern this afternoon and this evening especially across the east coast metro areas. High temperatures this afternoon will remain seasonal as they will range from the upper 80s across the east coast to the lower 90s across the interior sections.

PREV DISCUSSION . (Issued 249 AM EDT Fri Sep 17 2021)

SHORT TERM .

Today and Tonight:

Surface ridging associated with high pressure over the Atlantic waters will branch into the region with support aloft provided by a mid-level anticyclone centered north of the Bahamas. With South Florida located along the low-level ridge axis light winds should prevail with the development of both Atlantic and Gulf sea breezes anticipated. This pattern should initially produce scattered showers and storms over the Gulf and Atlantic waters during the morning, with rain chances spreading inland through the morning to early afternoon hours. While coverage may initially peak of the Lake Okeechobee and Everglades areas, S-SW steering flow and thunderstorm- generated outflow boundaries are likely to push showers and storms back towards the east coast metro areas during the afternoon to early evening. Given precipitable water values of 2 to 2.25 inches, tall/skinny CAPE profiles, and slow storm movement, urban/street flooding should remain the primary weather-related concern along the east coast today. Any stronger storms should be the exception rather than the rule given modest temperatures aloft and meager mid-level lapse rates. Highs should range from the upper 80s along the Gulf coast and around Lake Okeechobee to the lower 90s across the east coast metro areas. Convection should gradually wane through the evening hours over land areas although a few showers and storms may continue overnight over the local waters. Lows will generally be in the 70s, with some lower 80s along the Atlantic beaches.

Saturday:

A weakness in the mid-level ridge will develop along the Eastern Seaboard as upper troughing moves offshore. While the trough should remain well north of the region some perturbations are noted in vorticity fields as far south as central Florida towards the Lake Okeechobee region. A light synoptic wind regime should prevail through the low-levels, with both sea breezes again expected to develop. Given a continuation of the light S-SW steering flow and rich moisture expect a similar pattern to Friday with morning development along the breezes and afternoon coverage peaking over the interior. Once again thunderstorm outflows may again push convection back towards the east coast metro areas during the afternoon and evening, with localized flooding again the primary weather-related hazard. Highs will generally be the lower 90s away from the coasts with the warmest readings favored over eastern inland portions of the area.

LONG TERM .

Saturday Night through Thursday:

A relatively moist airmass remains in place across South Florida this weekend as tropical moisture continues to advect across the peninsula along the periphery of a weakened Bermuda High. As the remnants of Nicholas slowly drift northwards in response to a cut- off low progressing over the southern plains this weekend, a stream of tropical moisture will continue to propagate into South Florida. With a saturated vertical profile and forecast precipitable water values remaining close to 2.0 inches throughout the weekend, scattered showers and thunderstorms will remain in the forecast, especially during the afternoon hours when differental heating and ample insolation will allow for convective activity along the sea- breeze and propagating outflow boundaries. Localized flooding and heavy rainfall remain the primary concern during this period as overall flow remains light and stagnant. With efficient rainfall rates and the possibility of a stalled sea-breeze boundary combined with already saturated soils, the concern for flooding will remain in the forecast. Frequent lightning and gusty winds are also possible with the strongest thunderstorm activity.

A developing upper-level low to the east of South Florida during the weekend will slowly propagate westward during the early portion of next week. There are still some differences in model depictions (placement and strength) of this feature at this time, however the presence of this feature aloft will allow for the steering flow to remain light across South Florida through mid-week with slightly cooler temperatures aloft. With the tropical moisture sticking around as well as a stagnant flow in the vertical column, hydro concerns continue through mid-week with no distinct "drying out" on the horizon for South Florida. Scattered to numerous showers and thunderstorms are possible each afternoon across South Florida, with seasonal temperatures expected for the area during the period.

MARINE .

Winds and seas will be light as the high pressure ridge remains near the area, with daily wind speeds no more than about 10-12 knots and seas 2 ft or less. Showers and thunderstorms will be most numerous over the Gulf waters today, then more evenly distributed across the local waters this weekend and early next week. Waterspouts and locally higher winds and seas are possible in showers and thunderstorms.
