Temperatures this morning in North Florida have not been this cool since mid-May. You may want to grab a light jacket before heading out the door for school or work. Highs climb into the upper 70s later today. #FLWx #Fall

It’s easy to see where the front had made it, and where it had not as of this morning. Coolest spot was #PanamaCity with a low of 49°!#FLwx

The coolest air yet of the young fall season is expected to arrive Sunday across the Sunshine State. Noticeably lower humidity values are expected as far south as Miami.

The ridge of high pressure that has been responsible for the recent stretch of above-normal warmth across the Southeast will be replaced by an approaching cold front Saturday night. Upper-level winds will steer the front deep into South Florida by late Sunday.

The cooler air will be first felt in the Florida Panhandle Saturday night, where overnight lows will dip into the 50s. The cooler air will then spread south and east into north-central Florida during the day Sunday, where high temperatures will struggle to hit 80º. This will be 10 to 12 degrees cooler than afternoon highs have been for these locations in recent days, and Sunday night low temperatures could dip into the 50s as far south as the I-4 corridor. Temperatures will only cool by a few degrees behind the front in South Florida Monday, but humidity levels will drop enough to make for more pleasant evenings and mornings.

Rainfall will be minimal along the front due to a lack of moisture and its fast forward motion. Nonetheless, scattered showers will mark its arrival across the Florida Panhandle Saturday afternoon, North Florida Saturday night, and during the early part of the day Sunday in central and south Florida.

In the tropics, the Atlantic basin has been relatively quiet and it will most likely stay that way for the next several days. There is an area of low pressure the National Hurricane Center is watching northeast of the Turks and Caicos Islands. However, it only has a ten percent chance of development and is moving farther away from the land to the east-northeast.

Afternoon highs are on track to approach or achieve their daily records, especially Thursday and Friday mainly over the interior and Gulf side of the peninsula.

A large high pressure ridge over the central Gulf coast will move over the Carolinas this week. East winds over the state, combined with a warm airmass, may cause a few records to be tied or broken. Tampa's forecast high of 91 degrees on Thursday would be within 1 degree of its record high set just last year. Fort Myers forecast high of 91 would also be within 1 degree of its record high set two years ago, in 2019. Leesburg is expected to top out in the lower 90s on Friday, which would approach its record of 92 last set in 2018.

Areas that do not tie or surpass their record highs will experience above normal temperatures, especially over the Panhandle and the northern and central peninsula. Average highs are generally in the lower 80s over the Panhandle, and mid 80s over north and interior Central Florida. Highs are expected to run about 5 degrees above average for most of the week. The exception to the warmer-than-usual temperatures will be along the Atlantic coast, especially from the Space Coast south to the Treasure and Gold Coasts. A stronger easterly flow from the Atlantic will have a moderating effect on these areas.

A cold front will move through the Panhandle Saturday afternoon and evening, with somewhat cooler temperatures there on Sunday. The front will stall over central Florida Sunday and Monday, with a modest decrease in temperature by early next week.

More: There are three areas with low chances of development in the next five days. However, windows of opportunity will be brief due to strong winds aloft engulfing much of the western Atlantic and Caribbean next several days. #flwx
