PREV DISCUSSION. (Issued 315 PM EDT Thu Sep 23 2021)

.Increasing Risk Of Rip Currents East Coast Beaches This Weekend. .Drier Conditions Possible Early Next Week Behind A Cold Front.

SHORT TERM (Rest of Today through Friday) .

A frontal boundary is currently working its way down the Florida peninsula. Ahead of the front light S/SW wind flow across South Florida with abundant tropical moisture and precipitable water values around 2 inches. Scattered to numerous showers and thunderstorms over the interior and east coast this afternoon and evening. Main impacts will continue to be the heavy rainfall and localized flooding. Showers and storms will continue to have very efficient rain rates as well as slow storm motion with a light mean wind vertical profile.

The frontal boundary begins to stall and wash out around the Lake Okeechobee region. However, we do get a wind shift to the NE, with light steering flow and storm motion remaining. Deep moisture will remain across South Florida since the boundary stalls before reaching the region. Another day of scattered to numerous showers and thunderstorms favoring the eastern half of the region. Heavy rainfall with efficient rainfall rates and slow storm motion leading to the potential for localized flooding. Antecedent conditons with numerous days of heavy rainfall across the area will only enhance the potential for flooding for these areas that have seen heavy rainfall in previous days.

Temperatures will remain seasonal, with highs in the upper 80s to lower 90s and lows in the 70s

LONG TERM (Friday Night through Thursday) .

The long term period starts out with a frontal boundary remaining stalled out over the Lake Okeechobee region or just to the north. With deep moisture advection remaining in place out ahead of the front, the chances of showers and thunderstorms will remain in place especially through the first half of the weekend. The lower level wind flow will remain out of the northeast and it will be rather light through Saturday. A strong thunderstorm or two cannot be ruled out during the afternoon hours especially over the Lake Okeechobee region closer to the frontal boundary. The potential for localized flooding will remain in place on Saturday due to the slow storm motion and heavy rainfall with stronger thunderstorms.

On Sunday, the weather pattern begins to change as the front starts to move southward through the area due to a trough moving to the east of the region and amplifying. This will help to suppress the moisture advection out ahead of the front to the southern portion of the area as drier air moves in from the north. The highest chances of showers and thunderstorms will remain across the southern portion of the region near and along the front.

For the early to middle portion of next week, the latest guidance continues to show the frontal boundary remaining off to our south which will allow for the drier air mass to move across South Florida during this time frame. Chances of showers and thunderstorms will remain limited through the middle portion of the week as the dry air continues to filter in. Temperatures will remain where they should be for late September, however, there should be a noticeable drop in humidity during the early portion of next week. High temperatures on Monday and Tuesday will generally remain in the upper 80s to around 90 across most of South florida.

AVIATION(18Z TAFS) .

Scattered to numerous showers and storms this afternoon and evening, with highest coverage over the interior and east coast. MVFR/IFR cigs and vis possible with convection that move over the terminals. L/V winds once again overnight tonight. Winds will be NE tomorrow with showers and storms possible.

MARINE .

High pressure with light southerly and southwesterly winds ahead of an approaching front that will stall north of the area. Winds will shift to northeasterly for the weekend. Fairly benign marine conditons over South Florida waters outside of convection. Scattered to numerous showers and thunderstorms over local waters throughout the rest of the week into the weekend. Waterspouts and locally higher winds and seas are possible in showers and storms.

There is also a long period swell of 1 to 2 feet that will be working into the Palm Beach Atlantic waters from the north tonight into Friday night. This will allow for the Palm Beach Atlantic waters to increase to 2 to 4 feet on Friday. Rest of the Atlantic waters will be at 2 to 3 feet on Friday. The Atlantic waters will then decrease to 2 feet or less for this weekend. The Gulf Waters will remain at 2 feet or less through the weekend.

BEACHES .

A long period swell over portions of the northern east coast will allow for an elevated risk of rip current Friday and into the weekend for Palm Beach County beaches. Also, the winds will be increasing to moderate conditions this weekend from the northeast. This will also allow for the risk of rip currents to increase along Broward and Miami-Dade beaches this weekend.
