Our focus now turns to the potential of record lows tonight. Many areas may wake up to thermometer readings below zero.
WASHINGTON (AP) - It's been so warm in the United States this year, especially in March, that national records weren't just broken, they were deep-fried.
Temperatures in the lower 48 states were 8.6 degrees above normal for March and 6 degrees higher than average for the first three months of the year. That's according to calculations by the National Oceanic and Atmospheric Administration and it far exceeds the old records.
The magnitude of how unusual the year has been in the U.S. has alarmed some meteorologists who have warned about global warming. One climate scientist said it's the weather equivalent of a baseball player on steroids, with old records obliterated.
