KEY MESSAGES

Updated at 606 AM EST Sun Nov 23 2025

- Dry and pleasant conditions will remain in place across South Florida this weekend. - Patchy dense fog is possible early this morning, mainly across the Lake Okeechobee region as well as interior Southwest Florida.

SHORT TERM

(Today through Monday) Issued at 111 AM EST Sun Nov 23 2025

Sensible weather conditions across South Florida will generally remain unchanged through the short term period, despite the gradual approach of a weak frontal boundary currently draped over the southeast CONUS. The boundary is forecast to stall out somewhere over northern/central Florida as we head into the new week. Nevertheless, the main impact of this frontal approach will be a brief wind shift from the north/northeast expected today. However, with ridging prevailing aloft and meager moisture along the atmospheric column ahead of the front, chances for any convection associated with this boundary will remain very low. Additionally, despite the brief northerly wind shift, the cooler airmass will not reach our area, and temperatures will remain warm, with highs in the low-mid 80s this afternoon. Winds veer back fro the east-northeast on Monday, and the dry and warm pattern will continue.

LONG TERM

(Monday night through Saturday) Issued at 111 AM EST Sun Nov 23 2025

Ridging will become re-established over the first half of the week as the surface high over the western Atlantic builds back over the Florida peninsula. This will usher in the return of easterly flow and a slight uptick in moisture (up to 1.0-1.3 inches over the first half of the week). This could result in slightly warmer feels-like temperatures each afternoon; with high temperatures in the mid to upper 80s each day, the apparent temperatures could start approaching the low 90s by Wednesday afternoon.

As we head into the long holiday weekend, a stout upper level trough will develop over the Great Lakes region, spawning a strong surface low and associated cold front which will sweep across the nation and south across the Florida peninsula sometime between Friday and Saturday. There is some divergence regarding timing in the ensemble envelope, with the european ensembles favoring a faster progression, and the GFS looking at a slower evolution. We will continue to monitor those differences as we near the end of the week.

With enough moisture pooled over the region ahead of this front, this could mean a general increase in the chances for rain starting on Thursday and continuing through the end of the period, with PoPs in the 20-40% range each day. Temperatures could also drop slightly over the weekend once the cooler airmass moves over the area, with highs in the high 70s and lows in the mid 60s and low 70s.

AVIATION

(12Z TAFS) Issued at 606 AM EST Sun Nov 23 2025

Winds become north-northwesterly in the late morning. Sea breezes will develop along both coastlines in the early afternoon, ushering a return to easterly flow for East Coast terminals, and westerly flow at KAPF.

MARINE

Issued at 111 AM EST Sun Nov 23 2025

Light northerly breeze will develop later today with a weak boundary approaching. Easterly flow will becoming re-established on Monday. Seas will remain in the 1-3 feet range. Winds and seas could build as a stronger boundary approaches later in the week, but timing and intensity remain somewhat uncertain at this time.
