How low can it go?
The Philadelphia region set a frigid record Saturday recording a high temperature of just 15 degrees, three degrees chillier than the previous record of 18 in 1942.
At least another record was expected before this wickedly cold weekend's end. A temperature of zero is forecast for 6 a.m. Sunday. The region hasn't seen a temperature that low or lower since Jan. 19, 1994, when the thermometer hit 5 below – and we're not talking the discount retail store.
If Saturday felt colder than 15 degrees, that's because it was! The wind chill had it feeling more like minus 1 and will make the forecasted zero feel like minus 11.
The National Weather Service has a wind chill advisory in effect until 10 a.m. Sunday. It warns that frostbite can happen in as little as 30 minutes for exposed skin.
