KEY MESSAGES

Updated at 1207 AM EST Sat Jan 31 2026

- The odds of impactful and dangerous cold across South Florida continues to increase, with apparent temperatures and freeze potential not seen since at least 2010. Members of the general public and agricultural interests are advised to prepare accordingly.

- Dangerous marine conditions will develop rapidly behind a strong cold front on Saturday afternoon with winds increasing overland. Mariners should stay up to date with the latest marine forecast over the next several days.

- Gusty winds will increase rapidly behind the front on Saturday afternoon, resulting in the potential of gusts of 40 to 45 mph overland. A Wind Advisory will go into effect between 2PM Saturday to 7AM Sunday. Secure loose objects properly!

Saturday and Saturday night

The strong arctic cold front will move through South Florida Saturday morning and into the Florida Straits by Saturday night. Scattered showers will be possible over South Florida Saturday morning, except numerous over the Gulf waters and Naples. There could be a thunderstorm or two over the Gulf waters and the metro areas of Collier County, but the coverage will not be enough at this time to mention it in the forecast.

The weather should then be dry over most of South Florida Saturday afternoon into Saturday night. However, there will still be some moisture over the Gulf of Mexico Saturday night that will allow for a few showers to develop and work into the metro areas of Naples Saturday evening on the northwest wind flow. While the chances are extremely low, a few mesoscale models hint at a brief window for the combination of temperatures below freezing and enough low level moisture in the boundary layer to support the potential of a few flurries west of Lake Okeechobee and across coastal southwestern Florida. The main focus however should be on the potential of the coldest temperatures since at least 2010, perhaps even 1989 across portions of the area. More on the forecast low temperatures and wind chill details below.

Low pressure will develop and quickly drop into the 970s mbs off the Carolina coast late Saturday night as strong high pressure shifts into the Southern Gulf coast States from the north. This will allow for the pressure gradient to quickly tighten over South Florida Saturday afternoon and remain tight through Saturday night allowing for windy to very windy conditions. Therefore, A wind Advisory has been issued for all of South Florida Saturday night into Saturday night.

Highs on Saturday will be in the late morning hours with mostly 60s over the region except around 60 near Lake Okeechobee. Temperatures will then quickly fall through Saturday afternoon and be around 40 west of Lake Okeechobee to mid to upper 50s southeast coast.

Temperatures will continue to drop quickly Saturday evening into early Sunday morning and should be in the mid to upper 20s west of Lake Okeechobee with 30 to 33 over rest of the interior areas. The metro/coastal Palm Beach County near freezing conditions. The metro/coastal areas of Broward, Collier, and Miami-Dade Counties is forecast to get down into the mid to upper 30s late Saturday night. However, there is still a 30 to 50 percent of getting to freezing over the metro areas of Broward and Miami-Dade County and 10 to 20 percent over Collier County for late Saturday night. Will continue to monitor the latest models to see if a Freeze warning will be needed for Saturday night for the metro areas of Miami- Dade and Broward Counties.

With the windy to very windy conditions over South Florida Saturday night, the wind chill readings should be able to fall into the teens over the Lake Okeechobee region and upper teens to lower 20s over metro/coastal Palm Beach County. Rest of South Florida will see wind chill readings in the lower to mid 20s, except for the metro areas of Broward and Miami-Dade Counties and mid to upper 20s over metro Collier County. Therefore, the Extreme Cold Watch has been upgraded to a Extreme Cold Warning for Glades/Hendry/Palm Beach Counties. A Cold Weather Advisory has also been issued for the Counties of Collier/Broward/Miami- Dade/Mainland Monroe Counties.

Early to Middle Of Next Week

High pressure will be slowly moving east into the Atlantic waters through early next week allowing for a slow warming trend. However, highs on Monday will still be in the 50s before increasing to 60s on Tuesday.

Monday night will again be a cold night with temperatures in the mid to upper 30s, except around freezing west of Lake Okeechobee and around 40 east coast metro areas. Tuesday night will be warmer with lows in the 40s, except around 40 west of Lake Okeechobee and 50s east coast metro areas.

Another Cold front is forecast to move through South Florida middle of next week bringing in some more cooler weather to South florida for late next week.
