Florida weather forecast heat, cold front Saturday. How cold?

The Miami-Dade Youth Fair opens on March 17, but before this annual attraction arrives, Florida weather may cause the thrill of a ride on the Mega Drop.

Think of a high spike and then a sudden drop. You will feel the extremes.

The highs will remain in the lower 80s throughout the week, with lows in the mid 70s. That looks about right for March in Miami.

Then Saturday comes.

A near record is expected as temperatures hit 86 degrees in South Florida, according to the National Weather Service in Miami. The record for that March date is 87 degrees, according to CBS4 meteorologist Dave Warren.

Just when you think that week-long warming trend was in the city earlier this year, Saturday night is fast-paced and drops temperatures to around 58 degrees, a drop of almost 30 degrees.

Bomb Cyclone

Blame it on a “bomb cyclone,” also known as a weather bomb. It’s a weather term for when a storm’s barometric pressure readings drop more than 24 millibars in 24 hours, according to the National Weather Service. The storm can be a severe thunderstorm, blizzard, heavy downpour, or other associated weather phenomenon, according to The Conversation and reported by Scientific American.

Such a storm system is expected to head into Florida Friday night through Saturday night as it tracks northeast across the eastern United States, CBS4 reports.

Wind Chill

Wind chill values ​​— what it really feels like when exposed skin encounters both cool temperatures and high winds simultaneously — could be in the upper 30s on weekends in the Lake Okeechobee area and inland. of South Florida, Weather Services meteorologist Paxton Fell wrote in her Dangerous Weather Outlook. Wednesday morning. Wind chill temperatures in the 40s will be possible on the Gulf Coast and inland parts of South Florida, she added.

Sunday afternoon highs are only expected to reach around 71 degrees – 10 degrees lower than the days leading up to Saturday evening and the big Sunday morning drop.

But then, like the Mega Drop ride at the fair, we get another ride to the top pretty quickly.

“The wind is quickly shifting northeast and eventually east Sunday night and Monday, warming temperatures quickly. Highs will be back near 80 degrees Monday afternoon,” CBS4’s Warren reports.

The Florida Keys will also feel the cold front, but will be warmer, with an expected low in the mid-60s, according to the Key West Weather Service. But if you plan to sail, expect small craft advisories, as winds up to 25 knots and higher gusts are possible.

Other weather conditions

Showers and thunderstorms could start Wednesday afternoon and dot the area daily through Saturday.

“A rumble or two of thunder can’t be ruled out with lightning strikes,” Fell said in Wednesday’s forecast.

But the highest risk of bad weather is 50% on Saturday afternoon, the weather service predicts.

Shifting winds ahead of the cold south and southwest front are expected to sweep afternoon showers and storms inland, then east across Miami-Dade and Broward, the forecast says. of Warren.

Watch for a high risk of rip currents through the end of the week and over the weekend along the Atlantic coast, the weather service warned. High waves are also possible along the Palm Beach and Gulf Coasts on weekends, creating hazardous sea conditions as the cold front passes overhead.

“This weekend’s winds could approach wind advisory thresholds,” Fell predicted. Wind advisories are typically announced when there are sustained winds of 31 to 39 mph, for an hour or more and wind gusts of 46 to 57 mph for any length of time, according to the National Weather Service.

Tampa Bay Forecast

Bradenton and around Tampa Bay follow a similar schedule of hot then cold on Saturday — but even colder and with a much stronger 90% chance of a storm on Saturday, according to meteorologist Austen Flannery of the National Weather Service in Tampa Bay.

Those thunderstorms could hit Tampa Bay with strong gusty winds, heavy rain and “frequent killer lightning strikes,” Flannery predicted in the service’s hazardous weather forecast for the week.

Saturday’s low will be around 41 degrees, with north winds of 17 to 21 mph and gusts of up to 29 mph.

Orlando

Expect lows of 39 degrees Saturday night and just 63 degrees Sunday, according to the Orlando Weather Service forecast. High risk of rain and thunderstorm from Thursday to Saturday, within a range of 70% to 80%.

“An unusually warm and unstable environment will bring numerous showers and severe scattered thunderstorms Thursday and Friday,” Orlando meteorologists Rob Haley and Derrick Weitlich said. Some of those storms could be locally severe in north-central Florida, including the Space Coast to the Orlando metro and the I-4 corridor, weather experts said.
