Issued at 131pm EST Thu Jan 1 2026

Cold air advection continues to diminish across the region as northwesterly wind flow subsides further. As the winds become light and variable tonight, it will be another good night for radiational cooling to take place. However, with cold air advection beginning to end, temperatures will not be as cold as they have been over the past couple of nights. Low temperatures tonight will generally drop into the lower 40s across the Lake Okeechobee region and interior portions of Southwest Florida. The east coast metro areas as well as coastal areas of Southwest Florida will have low temperatures drop into the upper 40s to lower 50s.

.SHORT TERM... (Today through Friday) Issued at 1203am EST Thu Jan 1 2026

Happy New Year! We start the year off cold across South FL with surface high pressure over the Gulf allowing a dry northerly flow across the area, as shown by our 00Z sounding which only had a PWAT (Precipitable Water) value of 0.25 inches. Mainly clear skies and nearly calm winds this morning is allowing temps to plummet again. A Frost Advisory is in effect until 9am for Glades, Hendry, inland Collier, and inland Palm Beach. Some patchy frost will even be possible over western portions of Miami-Dade and Broward early this morning.

Temps warm up quickly today until mostly sunny skies, however highs this afternoon will remain well below normal, only reaching the upper 60s to lower 70s. Not as cold tonight but remaining chilly with overnight lows around 40 west and south of the lake, to around 50 closer to the coasts.

High pressure shifts over the area on Friday. Winds will remain light and variable throughout the day. Skies will be partly cloudy in the afternoon and high temps will reach the low to middle 70s.

Long Term
(Friday night through Wednesday) Issued at 1203am EST Thu Jan 1 2026

As high pressure shifts east of the area this weekend, temps will continue to moderate as the low level flow becomes more southerly. High temps this weekend will be around normal in the upper 70s to around 80. Overnight lows Saturday night will be in the 50s/60s.

Low pressure system over the southeast US will move off the Mid Atlantic coast on Sunday, and a frontal boundary associated with that system along with an upper level shortwave will cross South FL late Sunday into early Monday. This will bring with it the only chance of rainfall in the extended period on Sunday, albeit only slight chance PoPs, and certainly nothing that will bring any relief to the ongoing drought. Once the frontal boundary passes, high pressure builds back into the region for the early part of next week. Temperatures will remain right around normal through mid week.

Marine
Issued at 1203am EST Thu Jan 1 2026

Moderate northerly winds today over the area waters become a light to gentle west to southwest breeze on Friday. Seas 2-4 ft in the Atlantic today and 1-2 ft in the Gulf.

Beaches
Issued at 1203am EST Thu Jan 1 2026

Lingering swell will result in an elevated risk of rip currents today for the Palm Beaches.
