So much for global warming

Emily Babay has an article at Philly.com about the weather:

Philadelphia-area residents woke up to spring-like temperatures this morning, but that warmth is about to turn to potentially record-breaking cold.
The temperature at Philadelphia International Airport had reached 59 degrees by 6 am. In the next 24 hours, the mercury will drop fifty degrees, forecasters say.
The National Weather Service says to expect low temperatures in the single digits, likely around eight or nine degrees, overnight into Tuesday morning. The high Tuesday is expected to reach just twelve degrees in Philadelphia.
Those temperatures could set new records. The lowest ever recorded temperature for a 7 January in Philadelphia is seven degrees, and the lowest maximum temperature for the date is twenty degrees.
The wind will bring an added chill Tuesday, with fifteen to twenty mph winds expected, and gusts of up to thirty-five mph. Expect wind chill values as low as thirteen below in Philadelphia, and as low as minus thirty farther north in the Poconos, the weather service says.
Wind speeds should decrease gradually Tuesday night into Wednesday and the temperature will rise, though Wednesday is also expected to be cold. Forecasters expected wind chill values as low as eight below in the morning, with highs in the twenties expected for the afternoon.
The Arctic-like blast comes as a low pressure system and associated cold front moves in from the eastern Great Lakes region. The cold and potentially dangerous wind chills will affect much of the United States, the National Oceanic and Atmospheric Administration says. Nearly the entire country, including areas as far south as Texas and Florida, is expected to see sub-freezing temperatures.
As many as 117 million people are under wind chill warnings, advisories and watches, according to the Red Cross.
The widespread cold accompanies a storm that dumped snow on the Midwest, where frigid temperatures are already in place. Crane Lake, Minnesota has posted the lowest temperature in the country over the past 24 hours, according to AccuWeather: The mercury there has dropped to minus 38. In Chicago, the temperature began falling by about two degrees an hour from midnight through this morning, the Chicago Tribune reports, reaching minus twelve by 5:30 am and hitting a record low of minus sixteen around 8 am.
The cold coming east could "bring the coldest temperatures some have experienced in twenty years", AccuWeather says.
The weather service warned of several problems the frigid temperatures could spur: Standing water will freeze tonight as the temperature drops, and roadway chemicals become less effective in the cold. Water pipes could freeze and burst amid the very low temperatures expected Tuesday and Wednesday mornings.
The weather is already causing problems for travelers: All flights at Philadelphia International Airport were stopped for part of the morning due to wind, and the airport was reporting numerous delays and cancelations. Peak wind gusts at the airport this morning reached 45 mph, the weather service said.

Rico says he'd hoped to never hear the phrase 'twelve degrees' again...
