The Northeast will get its one day of warmth on Thursday ahead of possible severe storms later in the day.
Temperatures were bitterly cold to start the week, making it feel more like the heart of winter. New York City and Boston barely cracked the freezing mark on Monday, when their highs were only 33 degrees. That's about 15 to 20 degrees colder than average for late March.
But Thursday is a much different story, as temperatures should be about 10 to 15 degrees above average by the afternoon.
Most of the region will warm into the 60s and 70s on Thursday, which means it'll be over 30 degrees warmer than Monday in many cities.
Boston and New York are both forecast to reach the mid-60s Thursday afternoon. Philadelphia and Washington might top 70 degrees.
Highs should manage the lower 60s from the eastern Great Lakes and upper Ohio Valley to upstate New York, including cities such as Cincinnati, Detroit, Buffalo and Albany, New York.
However, along with the warmup comes the threat of severe thunderstorms Thursday afternoon and evening. Severe storms are possible from northern Florida all the way up to New York's Hudson Valley.
Damaging wind gusts will be the main concern with these storms, but a few tornadoes can't be ruled out. The Southeast has the greatest threat of a tornado or two.
Slightly below-average temperatures will return to the eastern half of the country Friday into the weekend behind the cold front responsible for Thursday's severe weather threat.
