Area Forecast Discussion National Weather Service Miami FL 746 PM EDT Thu Apr 22 2021

AVIATION(00Z TAFS). VFR conditions are expected to prevail across all TAF sites through the forecast period. Isolated showers may develop along southeastern portions of South FL through the evening. Locally higher wind gusts and VIS reductions may accompany any shower that does develop. Winds generally NE becoming ENE by tomorrow. A Gulf sea-breeze may develop near APF and cause a SW wind shift tomorrow afternoon.

PREV DISCUSSION. (Issued 307 PM EDT Thu Apr 22 2021)

SHORT TERM (Through Friday) .

Latest surface analysis has South Florida wedged between two frontal boundaries; one that resides over the Florida Straits and another that is currently draped across the Lake Okeechobee region. Given there still remains ample moisture across the area, sufficient daytime heating could work together with the incoming frontal boundary to result in isolated convection this afternoon and evening, especially for the southern inland and metro areas. While updraft strength should be limited with other factors for severe convection being less favorable, can't rule out locally gusty winds with any stronger storms that develop.

High pressure then builds into region on Friday, resulting in breezier conditions across South Florida as the pressure gradient tightens. Additionally, surface winds will continue veering out of the east, maintaining rich boundary-layer moisture across the area. This enhanced low-level moisture, combined with daytime heating and weak lift generated by the frontal boundary in the vicinity could provide the necessary ingredients for another day of isolated showers and thunderstorms. Albeit, modest forcing for ascent should once again act to limit intensity of any storms that develop.

LONG TERM (Friday Night through Thursday) .

A shortwave is forecast to move from the Southern Plains through the Deep South, and off the Mid-Atlantic coast over the course of the weekend. At the surface, the associated frontal boundary will reach central Florida by the end of the weekend and become more diffuse and eventually wash-out over south Florida. A high amplitude ridge will build in behind the shortwave early next week, followed by a high amplitude trough to end the period. There's still quite a bit of uncertainty regarding the depth and timing of the mid-to late week (next week) trough, but worth watching late next week as it could result in a rather dynamic system moving through the Deep South.

As far as the local sensible weather is concerned, veering flow around the sub-tropical ridge will result in a more moist and unstable airmass advecting northward. This will result in nightly Gulf Stream convection that may advect inland along the southeast Florida coast both Saturday and Sunday morning. Scattered showers and possibly a storm or two will be possible along the aforementioned, weakening frontal boundary Sunday into Monday, but most of the forcing associated with that front will be far removed from South Florida. The remainder of the period will remain mostly dry with mainly just scattered convection along the Gulf Stream and adjacent coastal areas.

AVIATION(18Z TAFS) .

Predominately VFR conditions will prevail across the TAF sites through the forecast period. Isolated SHRA/TSRA may develop later this afternoon/evening, particularly over SE portions of South Florida. Locally higher wind gusts, VIS reductions, and lightning may accompany any developing storm. Winds generally NE becoming ENE as time progresses, aside from the Gulf coast where a developing sea-breeze may cause a westerly wind shift near APF.

MARINE .

Generally benign marine conditions prevail today outside of isolated showers and thunderstorms across the Atlantic waters, where locally gusty winds will be possible. As a weak frontal boundary quickly pushes through the area, strengthening easterly winds will result in cautionary conditions across the local waters from Friday morning through the upcoming weekend.

BEACHES .

The risk of rip currents will increase across the Atlantic beaches late this week and remain elevated through the upcoming weekend as onshore winds strengthen.
