They can expect frightening temperatures on Halloween this year, meteorologists said.
Extreme cold could reach parts of the United States toward the end of October, according to the National Weather Service. A “strong” cold front is scheduled to move through the Gulf Coast and East Coast states by Monday night.
“It might be a good idea to figure out how to incorporate a jacket into this outfit tomorrow night in most of the lower 48,” the National Weather Service said on social media. mail. “Mr. Freeze is a good costume, but only if it's intentional.”
Which parts of the United States will see below average temperatures?
Most of the central and eastern United States will see below-average temperatures on Tuesday and Wednesday, said Dr. Rick Knapp, a meteorologist at The Weather Channel.
“Temperatures will be cold enough on Halloween night for most of the eastern two-thirds of the country that jackets will be needed — unless you can strategically wear warm layers under your costume to stay warm,” the meteorologist said.
The Plains, Midwest, parts of the Tennessee Valley and the Appalachians will see the coldest temperatures on Halloween itself, Knapp said. Projections indicate that temperatures in these areas will be 20 to 30 degrees Fahrenheit lower than average for this time of year.
Temperatures are expected to be about 10 to 20 degrees below average and slightly above elsewhere east of the Rockies, Knapp said.
“Low temperatures (and cold highs) are expected to arrive Thursday morning from northeastern Texas into the Ohio and Tennessee Valley regions, and even in some locations along the East Coast from South Carolina to Maine,” Knapp said.
How long will the cold last?
Knapp said the cold snap is expected to continue until Thursday. Temperatures will be around average in most areas by Friday or the weekend.
Freeze watches and warnings have been issued for this week from central Arizona through the Southern Plains and into the Midwest and Ohio Valley, according to the National Weather Service. The organization issues a freeze watch when there is a possibility of significant and widespread freezing temperatures within the next 24 to 36 hours.
Knapp said that more than 100 million people will see temperatures below zero on Tuesday morning, and the number will rise to 165 million people on Thursday morning.
Is there any rain, wind or snow in the forecast for Halloween?
According to the National Weather Service, there may be rain or snow showers in the upper Midwest, Great Lakes and interior Northeast through Wednesday. Parts of the Midwest will also deal with “cold, gusty winds.”
Forecasts show northern Maine could see accumulating snowfall. Blizzards are possible across parts of the northern Plains, upper Midwest and Great Lakes during Halloween.
