More than 1,200 record high temperatures have been set over the past week across the U.S., AccuWeather.com reports.
Additionally, nearly 6,000 record highs have been documented since the beginning of 2012.
From March 8 to 14 of this year, the total number of weather setting records is 1,226, according to the National Climatic Data Center.
On Wednesday alone, 423 records were set.
To date, there have been 5,618 record highs. In comparison, over the same period last year, there were only 2,800 record highs recorded.
"The jet stream has been flung all the way north across central and eastern Canada," AccuWeather.com Expert Senior Meteorologist Alex Sosnowski said and explained why warmth has been so widespread this March.
"At least two-thirds of the nation could wind up with above-normal temperatures (this spring)," Paul Pastelok, expert long-range meteorologist and leader of the AccuWeather.com Long-Range Forecasting Team, said late in February. He forecast this spring could bring the most widespread warmth since 2004.
The warmth and humidity have been fueling an active start to the severe weather season, including rare tornadoes as far north as southern Michigan.
