Record breaking cold temperatures are expected to move into the area tonight and into Tuesday morning.
"We should have record breaking cold, the temperature could go as low as 10 below zero in Altoona," said AccuWeather meteorologist John Dlugoenski. "Wind chills will be in the 30-40 degree below zero range with the wind."
The record low for Altoona for Jan. 7 is 1 below zero in 1942, Dlugoenski said.
A cold front is expected to move across the area this morning and it is possible there could be some slick roads for the morning commute as rain showers could change to freezing rain or snow showers, said National Weather Service meteorologist Craig Evanego.
Temperatures are expected to drop throughout the day and will drop into the middle teens by the end of the day, Dlugoenski said. Winds could gust 40 to 45 miles per hour.
"It will be an amazing cold air mass," Dlugoenski said.
Tuesday's high is expected to be zero and Tuesday night's low about two below zero, Dlugoenski said.
People should stay inside if at all possible.
"If you go outside bundle up, it doesn't take very long for exposed skin to freeze," Dlugoenski said.
However, the cold air will not last.
Partly sunny skies are expected Wednesday with a high in the low 20s. Thursday could have a high in the low 30s.
