WATCH: Skywitness 9 flies over manatees at Blue Spring as coldest air of the season moves in

ORLANDO, Fla. — The coldest air of the season is moving into Central Florida Tuesday morning.

Skywitness 9 flew over the manatees at Blue Spring. Manatees can only be in waters cooler than 68 degrees for a short time, so once the water temperatures start cooling down, they migrate to regions of warmer waters.

Temperatures are about 20 degrees colder than they were Monday.

“We’re in for a really chilly afternoon,” said meteorologist Rusty McCranie. “Despite the sunshine, highs today are nearly 20 degrees below average.”

After the coldest morning in Orlando since March 1, Tuesday night will get even colder.

Meteorologist George Waldenberger said it’s all because the cold front that passed Monday opened the door for the coldest air yet this fall season. The winds are gusty and skies are clear and it won’t even hit 60 degrees Tuesday.

Tonight, the winds die down, which is nice, but that will just allow the temperatures to get even colder. Western Marion and Sumter counties are under a freeze warning Tuesday night through Wednesday morning.

Most other areas, including Orlando, have the threat for frost developing in areas tomorrow morning.

We’ll get one more chilly night tomorrow night, and then a brief warm up by Friday. Don’t get too used to it though, another cold front is coming this weekend!
