Area Forecast Discussion National Weather Service Miami FL 718 AM EDT Sat Sep 25 2021

AVIATION(12Z TAFS).

Quiet this morning with light winds and VFR. Scattered to numerous shower/storms developing around/after 17Z. Decent chance for on- station impacts at the eastern terminals this afternoon with at least brief ceiling/visibility reductions and gusty winds in thunderstorms. Expect light E-NE winds through early afternoon, with more variable directions possible by late afternoon/evening due to thunderstorm outflows. Quiet conditions should return after 02Z with light and variable winds overnight.

PREV DISCUSSION. (Issued 246 AM EDT Sat Sep 25 2021)

SHORT TERM .

Through Sunday

The stalled frontal boundary remains over the Lake Okeechobee region this morning. This front and a prefrontal trough further downstream helped enhance diurnally driven convection Friday afternoon and evening. Today will be similar as the front becomes passive with high pressure developing across the southern Appalachians and the mid level flow becoming parallel. Eventually, an upper level shortwave will merge with a weak trough amplifying over the western Atlantic on Sunday. This will help move the front through the CWFA finally bringing a much drier air mass aloft limiting convection from north to south later in the period. Sunday will be a transition day and with the dry upper levels sliding more into our region, the limited convection may contain a strong gusty winds, especially in the stronger/wider updrafts. Otherwise, shower activity overnight will be limited except where the better boundary layer moisture manifests over the Gulf Stream. Otherwise, no real "cool down" behind the front, but humidity values will be noticeably lower.

LONG TERM .

Sunday Night through Wednesday

A dry airmass will encroach on the region in the wake of a southward moving (modified) cold front. Mean steering flow will be directed out of the NE due to expansive surface ridging emanating from the coastal Carolinas, allowing a dry airmass to usher into South Florida. Some model solutions suggest precipitable water values of less than 1.0 in, which would be near the all time minimum per sounding climatology. Therefore PoPs do not exceed 25 through this period, and a lack of instability from decreased SFC-850 hPa dewpoints will significantly hinder thunderstorm chances.

Thursday through Saturday

Persistent, low-level northeasterly flow appears to remain intact by late next week, generally relegating tropospheric moisture to the lower quartile of climatological averages. With that said, a slight moistening does occur, and coastal convergence may allow for scattered showers and isolated thunderstorms to develop, primarily for the eastern half of the region. It appears that a (modified) cold front could usher in another brief spell of drier air by next weekend, however confidence is presently low based on this potential event being about one week away.

Temperatures will remain seasonable through the forecast period, as maximum temperatures in the upper 80s/lower 90s can be expected across the region. The passage of a modified cold front will allow for a reduction in dewpoints and hence apparent temperatures compared to traditional values for this time of year.

AVIATION(06Z TAFS) .

VFR conditions expected through the rest of the morning. Convection will again develop on Saturday afternoon. If storms move over a terminal, expect temporary VIS/CIG reductions. Winds will generally remain light and variable throughout the cycle. Convection should diminish at or shortly after sunset.

MARINE .

A light to moderate northeasterly flow will develop as high pressure sets up across the southern Appalachians this weekend. Despite a weak long period northeasterly swell developing, cautionary headlines are not expected through the weekend. However, scattered showers and thunderstorms will be possible, which may lead to localized gusty winds and higher seas.

BEACH FORECAST .

A weak northeasterly swell will lead to an elevated risk of rip currents along the Palm Beaches through the weekend.
