Tornadoes

... in December.



At least 6 dead, 23 injured after tornadoes touch down near Nashville

Six people were killed and nearly two dozen injured after tornadoes touched down around Nashville on Saturday, according to local authorities, who feared the death toll could rise as rescue efforts continued late Saturday night.

The severe thunderstorms that spawned the tornadoes erupted ahead of an intense cold front that stretched from Michigan through western Tennessee and into eastern Texas. Ahead of the front, abnormally warm and humid air — as much as 20 degrees higher than average for this time of year — surged northward, helping to fuel the storms.

More than 75,000 customers were without power in Tennessee as of Saturday night. The hardest hit areas appeared to be Clarksville, Tenn., and the northern side of Nashville. A child and two adults were killed in Clarksville, the city’s mayor said, and the Nashville Emergency Operation Center reported three people were killed by severe storms there.

“This is devastating news and our hearts are broken for the families of those who lost loved ones,” said Clarksville Mayor Joe Pitts, who declared a state of emergency and enacted a 9 p.m. curfew for Saturday and Sunday night. “The city stands ready to help them in their time of grief.”

Rescue efforts were still underway in both areas Saturday night. Photos from the Clarksville Fire Rescue showed at least two homes with their front facades and roofs torn off, a tractor-trailer truck that had been flipped onto its side and rescue workers scouring neighborhoods for people trapped or injured. Northeast of Nashville, utility poles, trees and power lines were downed in the nearby city of Gallatin, while buildings were at least partially collapsed in parts of neighboring Hendersonville.

Tennessee Gov. Bill Lee (R) directed the public Saturday night to follow guidance from local and state officials. “We mourn the lives lost,” he said in a social media post.

Through 8:30 p.m. Eastern, the National Weather Service had received about 75 reports of severe weather from northern Louisiana to southern Kentucky. But most of the severe weather was concentrated in western and central Tennessee, including 15 reports of tornadoes. The NWS said that as of 10 p.m., the severe weather threat had ended for all of Middle Tennessee.

The same front is forecast to barge toward the East Coast on Sunday. Some severe storms could erupt in the Southeast and Mid-Atlantic but they are not predicted to be as widespread or violent as Saturday’s storms in the Tennessee Valley.

In the Northeast, the front is expected to trigger torrential rains Sunday night into Monday morning. Flood watches are in effect from northern Virginia to eastern Maine, including Washington, Philadelphia, New York and Boston, where 1 to 3 inches of rain are predicted.

November wrapped up 6th-warmest autumn on record for U.S.

2023 Atlantic hurricane season ends as nation remains at 25 separate billion-dollar disasters so far this year

Last month wrapped up a remarkably warm meteorological autumn across the U.S., with the season ranking as the sixth-warmest autumn on record for the nation, according to scientists from NOAA’s National Centers for Environmental Information (NCEI).

A busy Atlantic hurricane season also came to a close, ranking fourth for the most-named storms in a year since 1950.

Below are highlights from NOAA’s U.S. climate report for November 2023:

Climate by the numbers


November 2023

The average November temperature across the contiguous U.S. was 44.4 degrees F (2.7 degrees above average), ranking as the 19th-warmest November in NOAA’s 129-year climate record.

November temperatures were above average across much of the U.S., while below-normal temperatures were observed in parts of the Northeast. No state in the contiguous U.S. saw its top-10 warmest or coldest November on record. However, Alaska saw its fourth-warmest November in the 99-year period of record for the state.

The nation’s average precipitation across the contiguous U.S was 1.38 inches (0.85 of an inch below average), ranking as the 12th-driest November on record. Indiana saw its third-driest November on record, while Illinois, Kentucky, Missouri and Wisconsin all saw a top-10 driest November. No state saw a top-10 wettest November.

Meteorological autumn

It was an exceedingly warm meteorological autumn (September through November) across the contiguous U.S. The average autumn temperature was 56.1 degrees F (2.5 degrees above average), ranking as the sixth-warmest autumn on record.

New Mexico and Texas saw their third-warmest autumns on record, while Maine saw its fourth warmest. Arizona, Colorado, Massachusetts, Minnesota, Montana, Nebraska, New Hampshire, Vermont, Wisconsin and Wyoming all had their top-10 warmest autumn.

The total autumn precipitation across the U.S. was 5.66 inches (1.22 inches below average), which ranked as the 15th-driest autumn on record. Tennessee’s autumn ranked as third driest, with three additional states — Indiana, Kentucky and Mississippi — seeing their top-10 driest autumn. No state ranked in their top-10 wettest on record for the September–November period.

Year to date (January through November 2023)

With just one month to go in 2023, the YTD average temperature across the contiguous U.S. was 55.8 degrees F — 2.0 degrees above average — ranking as the 10th-warmest such YTD in the record.

Louisiana, Mississippi and Texas each ranked warmest on record, while Connecticut, Florida and Massachusetts each ranked second warmest for the January–November period.

The YTD precipitation total for the contiguous U.S. was 26.89 inches, 0.70 of an inch below average, ranking in the driest third of the historical record.

Louisiana and Maryland ranked seventh and eighth driest on record, respectively, for this YTD period. Meanwhile, Wyoming ranked seventh wettest on record, while Maine, Nevada, New Hampshire and Vermont all saw their top-10 wettest such YTD.
