O INÍCIO DE INVERNO COM TORNADOS NOS ESTADOS UNIDOS

VÍDEO MOSTRA TORNADO NO MISSISSIPPI

Pelo  Radar Doppler vemos no dia 23.12.2014, a umidade vinda do El Niño com mais a umidade do Golfo do México, intensificou frente fria formada pela corrente de jato no sul dos Estados Unidos, causando muita chuva(em verde e amarelo) e até tornado na Louisiana. No norte, vemos em azul, a neve e até chuva congelada em rosa.
Na imagem de satélite abaixo, vemos mais claramente a umidade vindo do El Niño sobre o México em direção à Flórida. El Niño também causa temperaturas mais altas para essa época do ano nos Estados Unidos, principalmente no sul. E na Califórnia ainda, nada de chuva.

 Aqui na imagem em realce das 17h de 23.12.2014, vemos em maior detalhe a forte instabilidade em uma baixa pressão sobre o sul dos EUA e a umidade vinda do El Niño..

Pelo menos quatro pessoas morreram, nesta terça-feira (23), no Mississippi, sudeste dos Estados Unidos, na passagem de um tornado pela região, informou o governo estadual.
O governador do Mississippi, Phil Bryant, declarou estado de emergência nos dois condados mais afetados: Marion e Jones.
"Declarei estado de emergência para ajudar as autoridades locais com qualquer recurso estadual disponível que seja necessário nas áreas afetadas pelas duras condições climáticas,  especificamente nos condados de Jones e Marion", disse Bryant.

A tormenta deixou feridos, mas as autoridades locais ainda não sabem estimar esse número.
A legista do condado de Marion, Norma Williamson, relatou que há dois mortos e vários feridos.
No condado de Jones, o xerife Alex Hodge anunciou que também foram registrados dois mortos até o momento. Ele confirmou para a emissora de televisão que as duas pessoas que morreram estavam dentro um trailer, que foi totalmente destruído.
A companhia elétrica Mississipi Power reportou que 3.635 imóveis ficaram sem luz na cidade de Columbia, no condado de Marion, a 128 km da capital Jackson, e outros 935 no condado de Jones.
O tornado destriu casas nos dois condados, mas esses número ainda não foram contabilizados.
Espera-se que a tempestade continue, com vento e chuva de granizo. Além disso, existe a possibilidade de que alguns tornados, mais fracos, toquem o solo.
O Serviço Nacional de Meteorologia emitiu um alerta de tornado para algumas regiões dos estados de Alabama, Louisiana, Mississipi e Texas, e advertiu que em algumas áreas pode haver entre 30 e 120 milímetros de chuva e até 5 centímetros de granizo.

OKLAHOMA – Tonight looks mostly cloudy and much cooler than last night with highs in the mid to upper 40s and a northwest breeze at 10-20mph putting wind chills in the 30s.
Some extra moisture will head south out of Kansas and into northern Oklahoma tonight into Wednesday morning.
Because temperatures will be so cold at cloud level, light snow will be mixed in with the rain showers.
Temperatures here on the ground will likely stay above freezing, so roads won’t be a problem unless we see a heavier band of snow move in.
Otherwise, expect lows in the low to mid 30s and wind chills in the 20s by Wednesday morning.
Christmas Eve will start off cloudy in the morning and end with sunshine during the afternoon and evening.
Temperatures will struggle against that stubborn northwest breeze at 15-25mph, but we’ll at least get into the low to mid 40s and out of the 30s.
Christmas Eve night into Christmas morning will be chilly with lows in the upper 20s and lower 30s, but we’ll warm up nicely into the upper 50s and lower 60s with a southerly breeze at 15-25mph.
Stay tuned for updates!

Christmas Twisters: Deadly Storms Threaten Holiday Travel

An already hectic holiday travel week took a tragic turn Tuesday afternoon as at least four people were killed by tornadoes that swept through the south. Damage-causing twisters were reported in Louisiana and Georgia but the deadliest were in Mississippi.

The coroner in Marion County, Mississippi, reported two fatalities, as well as, several injuries, and the sheriff in Jones County reported two more people died when a tornado destroyed the mobile home they were in, according to NBC affiliate WDAM.

"If today's storm deaths prove to all have been caused by tornadoes, it will become the deadliest December tornado event in Mississippi since 38 died in the Vicksburg tornado of Dec. 5, 1953," according to Weather Channel senior digital meteorologist Nick Wiltgen.

Mississippi Governor Phil Bryant issued a state of emergency for those two counties at around 7 p.m. ET. Emergency management officials in Mississippi said that tornadoes closed U.S. Highway 98, damaged multiple homes and left some 8,000 customers without power. Golf ball-sized hail fell in Enterprise, Mississippi, along with some pea-sized hail in the Bude area.

The National Weather Service said a tornado watch was in effect late Tuesday for parts of Alabama, Louisiana, Mississippi and Texas and warned of the possibility of 2-inch-wide hail. Roy Lucksinger, a meteorologist for The Weather Channel, said 3 to 5 inches of rain was possible across the South. There were also reports of at least two other tornadoes Monday afternoon: One near Amite City, Louisiana, which caused tree and power line damage, according to the Weather Channel; and one near Valdosta, Georgia.

Meanwhile, flight delays began piling up at East Coast airports on Tuesday because of the tornado-storm system packing strong winds, thunderstorms, snow. Another system is threatening rain and heavy snow in the Northwest and Rockies. And dozens of flights were scrapped at Philadelphia International and at LaGuardia in New York, and delays ran as long as two hours.

The East Coast system will pivot to the north on Wednesday, bringing heavy rain and gusty winds into the Great Lakes. Chicago and Milwaukee could see "significant" snowfall toward the end of Christmas Eve, Lucksinger said.

"At the moment the system could just clip Chicago on Christmas Eve with potentially heavy snow that would certainly disrupt flights," Lucksinger added.

And a separate storm arriving in the Pacific Northwest on Wednesday is set to bring rain before moving across the Rockies. Salt Lake City could see up to 8 inches of snow on Christmas Day.
