If you think it’s cold now, just wait until Sunday and Monday morning. A second powerful polar air blast is on the way this weekend, and could produce the coldest temperatures in South Florida since the legendary and record-breaking freeze event of 2010.
Fort Lauderdale and Miami should experience lows in the mid-30s Sunday morning, with wind chills at or below freezing, according to The Weather Channel. Daytime highs will only reach the mid-50s. The Keys will drop to the 40s Sunday morning and stay in the 50s for the afternoon.
Temperatures in the western suburbs of Palm Beach County could drop to 32 degrees overnight Saturday into Sunday.
The National Weather Service said the last time temperatures dropped below 36 at Miami International Airport was Dec. 14, 2010.
According to the Weather Channel, the frigid wind is emanating from northern Canada, along the shores of Hudson Bay, and will descend south and reach the sunshine state overnight Saturday.
Early morning temperatures are projected to remain in the mid- to low-40s through Tuesday and rise into the 50s late next week.
Winds will be gusty and quite strong through the weekend, blowing 14 mph to 18 mph and gusting up to 34 mph.
“Wind chills are going to be very low starting Saturday night into Sunday,” said Caracozza. “We’re looking at the potential to drop to wind chills in the upper 20s here in the Miami area.”
Overnight wind chills will be as low as 20 in Jupiter, 23 in Delray Beach, 25 in Weston and 26 in Fort Lauderdale.
Why so cold?
In a nutshell, the already cold jet stream, which has been aimed at Florida, is getting supersized by a storm.

Meteorologist Chuck Caracozza with the National Weather Service said that a strong and rapidly developing storm will move off the Carolina coastline Saturday and into Sunday.
“The cold front associated with that system is going to move through the region and is going to drag unusually cold air down pretty far south,” he said.

The cold air we are experiencing this week will get a boost — the counterclockwise spin of the big storm off the Carolina coast will put a stronger pull on cold air from Canada.
“Everything is setting up in just the right place to create this kind of outbreak. It’s rare. The last time we had temperatures this cold was 16 years ago,” Caracozza said.
This weekend’s blast will have similar temperatures to a record-breaking 12-day cold spell in early January of 2010. Parts of Miami-Dade County dropped to 26 degrees.
The cause of the early 2010 blast was different, however. A high-pressure system stalled over Greenland and caused an atmospheric traffic jam where the cold jet stream remained aimed at Florida for almost two weeks.
It will be cold enough, in some spots, for snow, but Caracozza said that there won’t be enough moisture this far south, in South Florida, for even flurries.
