Much cooler across the whole state of #Florida compared to this time yesterday. Keep your jackets close tonight because the #FLPanhandle and parts of #NoFL are under a freeze warning. #flwx

There's a 30 degree temperature range across the mainland this morning: In the #Panhandle, temp are below freezing, while toward #Miami, they're in the 60s. #FLwx

The 2020 Atlantic Hurricane season was nothing short of historic, and many coastal residents are thankful the record-breaking season has come to a close.

Activity began early again this year, with Tropical Storms Arthur and Bertha forming in the month of May. Cristobal was the third name storm of the year, and it formed on only the second day of the season (June 2). Cristobal was the first of 27 named storms this year that set a record for the earliest formation date in a calendar year.

The 2020 season was filled with 30 tropical storms, 13 of which became hurricanes, and 6 achieved major hurricane status (Category 3 or higher on the Saffir-Simpson Hurricane Wind Scale). An average hurricane season typically produces 12 named storms, of which six become hurricanes and three major hurricanes. 2020 was the second season to use the Greek alphabet naming system, and it was the most active season in the Atlantic Basin since records began in 1851.

Of the 30 named storms, 22 total landfalls were recorded across the whole Atlantic. 12 of those made landfall in the contiguous United States, breaking the prior record of nine set in 1916. The Gulf Coast may have received the brunt of the direct hits this year, however, no coastline was spared from the threat of tropical cyclones. According to the National Weather Service Corpus Christi, tropical storm or storm surge watches and warnings were issued for every mile of U.S. coastline along the Gulf of Mexico and Atlantic Ocean.

September was the most active month on record in the Atlantic, with 10 named storms occurring that month. The season also featured a total of 10 tropical cyclones which underwent rapid intensification, tying it with the 1995 Hurricane Season. 2020 was the fifth consecutive above-average hurricane season and the first extremely active season since 2017.

The 2020 season was also the fifth consecutive season in which at least one Category 5 hurricane formed. Hurricane Iota became a deadly Category 5 hurricane with maximum sustained wind speeds of 160 mph, making landfall as a strong Category 4 hurricane in eastern Nicaragua, only two weeks after another Category 4 (Hurricane Eta) impacted the same area. Iota broke the record of the latest Category 5 hurricane to form in the Atlantic basin, reaching that status on Nov. 16.

Louisiana was hit the hardest, with five total landfalls this season, which is also a record. Category 4 Hurricane Laura impacted the state in late August, becoming the strongest tropical cyclone on record in terms of wind speed to make landfall in Louisiana, alongside the 1856 Last Island Hurricane.

These are only a handful of records that the 2020 Hurricane Season achieved and meteorologists attribute this unprecedented activity in part to an ongoing La Niña.

A La Niña is a natural ocean-atmospheric phenomenon marked by cooler-than-average sea surface temperatures across the central and eastern Pacific Ocean near the equator, the opposite of El Niño which produces warmer-than-average sea surface temperatures in that region. The opposite effect takes place in the Atlantic. During a La Niña the Atlantic experiences warmer than average sea surface temperatures and a weakening in vertical wind shear over the Caribbean Sea and tropical Atlantic basin, which enables cyclones to develop and intensify. NOAA scientists say there is a 75% chance that La Niña will continue to be in place from December 2020 through February 2021. This could extend hurricane season past the November 30th deadline.

November 30th may mark the official end to the hurricane season, however that does not mean tropical cyclones follow this schedule. The National Oceanic and Atmospheric Administration currently defines the hurricane season as occurring between June 1st and November 30th each calendar year, which is when 97% of all Atlantic tropical cyclones occur.

There have been a total of 87 off-season tropical cyclones to have formed in the Atlantic basin since 1851. Off-season tropical cyclones are most likely to occur in May, with approximately 60% of the total forming in this month. Only 15 tropical cyclones have formed in the month of December (5.8%).

Although the season came to a close Monday, meteorologists are continuing to watch an area for potential development over the far eastern Atlantic towards Europe. This broad area of low pressure could acquire subtropical characteristics over the next few days as it meanders to the north of the Canary Islands. Environmental conditions are forecast to become unfavorable for further development but at this time the system has a moderate chance for further development. If the storm develops it will be the 32nd cyclone and given the name Kappa if it achieves Tropical Storm status.

Rarely does nature follow the precise flip of the calendar, but as hurricane season officially ends, winter arrives in Florida.

The season's first freeze is likely across inland areas of the Florida Panhandle Tuesday morning, and subfreezing wind chills could dip as far south as the I-4 corridor in Central Florida.

A Freeze Warning is in effect tonight for all inland areas from Florida's Big Bend to Pensacola. Tuesday morning lows in the warned area will range from near 30 along the I-10 corridor to around 32 just a few miles from the coast. Temperatures are the beaches will fall to between 32 and 35. A Freeze Watch is in effect for Tuesday night and Wednesday morning across a large section of North Florida, when lighter winds and an even colder push of air will likely send the mercury below freezing in those locations.

A brisk north wind Monday night will send wind chills (what it will feel like) to the middle and upper 20s across most of the Florida Panhandle and North Florida by 7 am, and wind chills near or just below freezing are possible as far south as the outskirts of Orlando, Tampa and Lakeland.

This early winter-like air mass will make it all the way to South Florida as well, where Wednesday morning lows could fall to the 40s in outlying areas near Fort Myers, Naples, and Miami.

The cold snap will likely linger through Thursday, before temperatures gradually moderate back to normal for early December by the end of the week.

Expires at 10:00am on Tuesday December 1st, 2020

Can you find where the cold front is? It is currently approaching #SoFL where temperatures are warm in the low to mid 80s. Now that the front has moved through the #FLPanhandle and most of the Florida Peninsula temperatures are much cooler compared to this time yesterday. #flwx

Heaviest of the showers and a few gusty thunderstorms are expected to arrive in the Florida Heartland, including #Arcadia and #Sebring between now and 10 AM. The storms will also be near #FtMyers during the 10 o'clock hour. #FLwx

A line of gusty downpours and storms will approach the I-4 corridor from the west and arrive around or shortly after 8 AM, including #Orlando. Storms arriving in #Sarasota, #Bradenton, and #Lakeland before 8 AM. #FLwx

Freeze Warning late tonight for the #Panhandle. Temperatures of 28 to 32 degrees are likely for at least 2 hours within the warning area. Freezing temperatures can kill outdoor vegetation. #FLwx
