Synopsis..Light and variable winds will persist as surface high pressure builds over the region. A light onshore flow will then return Saturday afternoon and increase slightly into early next week. Moderate westerly winds are expected by Monday night ahead of a strong cold front approaching the area, with winds becoming more northerly on Tuesday as the front passes. Seas will decrease to around 1 foot through this weekend before building in the wake of the cold front next week.

Area Forecast Discussion National Weather Service Miami FL 726 PM EDT Fri Sep 25 2020

AVIATION(00Z TAFS).

Showers gradually ending early this evening with the exception of a few thunderstorms persisting over the Lake Okeechobee region. Prevailing dry/VFR into Saturday morning with VCSH/VCTS chances increasing towards the afternoon. Light and variable winds tonight should become SSW-SW by late morning, potentially shifting to the SSE-SE by mid/late afternoon at the Atlantic terminals in association with the Atlantic sea breeze.

PREV DISCUSSION. (Issued 355 PM EDT Fri Sep 25 2020)

Short Term (Today through Saturday) . A mid-level trough moving through the eastern United States and the remnants of Beta are bringing unsettled weather across a good portion of the southeastern US. Surface high pressure centered over the Atlantic has allow a southerly flow to develop over the area which remain fairly light to start the weekend. As the mid-level trough pushes into the Atlantic and deamplifies, mid-level high pressure will begin to build back over the region on Saturday.

Intermittent rounds of convection will continue to be the main concern through this afternoon and evening, and possibly into the overnight as well. The healthy moisture over the region, with the 12z MFL sounding featuring a 2.43 inch precipitable water value, creates the concern that training cells with efficient precipitation processes could lead to localized flooding. Also could see some storms tap into boundaries and other localized areas of vorticity which could lead to some spinning and the chance of stronger winds and enhanced rainfall amounts.

As the high pressure aloft builds and the generally flow begins to become lighter, the sea breeze circulations driven by diurnal patterns will begin to take a larger hold on things. For Saturday, the focus for convection may be inland including the western suburbs of Southeast Florida. Obviously, any force to arrest the progress of the sea breezes inland such as increased cloud cover from morning convection or a stronger westerly component to the flow could keep the convection closer to the east coast. Some of the stronger convection could produce gusty winds, torrential rainfall, and frequent lightning. Temperatures should still remain warm with upper 80s and lower 90s for the daytime high on Saturday.

Long Term (Sunday through Friday) .

Sunday through Tuesday

A ridge of high pressure - characterized by 500 hPa height maximum of roughly 592 dam - becomes fixated over Florida, with the center located generally in the offshore Gulf waters. This will induce modest subsidence via differential anticyclonic vorticity advection, as most of South Florida is beneath the eastern periphery of this upper anticyclone. Near-surface winds beneath the ridge will generally be easterly, which will act to focus convection over the Atlantic waters/metros in the morning, with a progression towards the interior/Gulf coast by the afternoon/evening. Given the unfavorable synoptic environment, stronger convection should be limited. The main threats through this period will be localized flooding, given that the steering flow will be weak in association with the upper level ridge. A swath of drier air appears to advect into the region Monday morning (forecast PWI < 1.25 ins), which should even further suppress storm activity though at least Tuesday. This is reflected in the latest forecast, with 30-40 PoPs over much of the Atlantic metros for Monday and Tuesday.

Wednesday through Friday

A vigorous short-wave trough and attendant frontal cyclone will transverse the Mid-Atlantic states, also sweeping down through the southeastern Gulf states. While the stronger forcing and advection of colder temperatures behind the front will stay well north of the region, there appears to be an inverted surface trough that acts to congeal moisture and increase convergence ahead of the main frontal boundary. A less hostile synoptic environment may act to increase the depth of moisture in the boundary layer, as well as reducing convective inhibition and lower the LFC (level of free convection). This may result in a widespread heavy rainfall event, where flooding appears to be the primary impact of concern. The orientation of this pre-frontal trough will dictate where the most favorable region for heavy rainfall will be, and it possible that the orientation allows for the heavy rainfall to stay away from the metro region. Though predictability of affected locations is low at this time, it will be an important feature to monitor heading into later next week.

Temperatures are forecast to be seasonable, with highs generally in the upper 80s/lower 90s, and a slight decreasing trend heading into later next week. The highest temperatures will likely be experienced over the interior, and where cloud cover is minimized. The stalled cold front will likely stay north of the region, though may provide some mild temperature relief in the form of widespread cloud cover and weak temperature advection.

Marine . As high pressure builds and swell continues to dissipate over the Atlantic, conditions for mariners will slowly improve. Shower and thunderstorm activity will be a concern through the weekend into early next week. Some of the showers and storms may bring locally gusty conditions and possibly even a few waterspouts.

Aviation . Unsettled pattern continues with bouts of sub-VFR possible with passing showers and storms. IFR/LIFR possible at terminals directly impacted by rain. There could be a break in the convection overnight. Short-fused amendments will likely be necessary through the period.

Beach Forecast . Conditions continue to improve though an elevated risk of rip currents along the Atlantic beaches may persist into the weekend. Southerly flow turning SW/W and diminishing swell will allow conditions to slowly improve into next week
