The coldest air of the winter so far has arrived over the northern Plains and Midwest and will cause temperatures to plummet in the Northeast in the wake of today's disruptive snowstorm. The wave of arctic air may lead to frozen pipes in some households and eventually broken water mains in some communities. Furnaces and heaters will be working hard in coming days, and you will get the bill for it later in the month. Actual temperatures may do no better than the single digits for highs today in Chicago and Milwaukee. The Great Lakes will modify the air slightly so that temperatures will manage to climb into the teens around Detroit today through the weekend. However, northern New England will make up for its lack of nasty cold so far this winter. Temperatures at Burlington, Vt., and Caribou, Maine, will struggle to reach zero degrees for a high Sunday. Even a swath from the central Plains to the Ohio Valley, southern New England and northern mid-Atlantic will have episodes of nasty cold. From St. Louis to Cincinnati, the coldest day will be today, with highs mainly in the teens, followed by a modest recovery Saturday and Sunday. Over the central Appalachians from Pittsburgh to Scranton, Pa. and Binghamton, N.Y., both days of the weekend will be bitterly cold with highs in the single digits and teens, depending on your elevation. For coastal areas of the mid-Atlantic and Northeast from Baltimore/Washington to Philadelphia, New York City and Boston, expect three days of January's finest cold. Highs will range from the teens in the north to the 20s in the south. The coldest days and nights will occur with relatively light wind. However, as the cold air first sweeps in from west to east, AccuWeather.com RealFeel® temperatures will be 15 to 30 degrees lower than the actual temperature. After the arctic cold has settled in, even a slight breeze will be painful. By the way, as cold as it will be by day, this air mass will produce temperatures of minus 20 degrees Fahrenheit from the Upper Midwest to northern New England at night. A number of locations may even get colder than that under clear skies and calm conditions. Temperatures in International Falls, Minn., plummeted to minus 44 degrees early this morning. That broke the day's record low of minus 41 degrees from 1954. The pattern will erase the above-normal temperatures experienced in northern New England since December (Caribou, Maine, was +9.4 degrees F above normal since Dec. 1., while Burlington, Vt., was +0.2 degrees and Portsmouth, N.H., was +1.8 degrees for the same period).

At least it shut Al Gore up permanent.

Does cold weather disprove global warming?
http://www.skepticalscience.com/global-warming-cold-weather.htm
Since the mid 1970s, global temperatures have been warming at around 0.2°C per decade. However, weather imposes it's own dramatic ups and downs over the long term trend. So we expect to see record cold temperatures even during global warming. Nevertheless, who hasn't heard someone on a cold day mutter "what happened to global warming?!" It's human nature to remember unusual events: record heat waves and freezing cold spells. Mentally calculating long term statistical trends doesn't come quite as easy as recalling that cold morning a few winters ago or that sweltering heat wave last summer. However, we can learn something about climate trends from those record hot and cold days.
Consider a record daily high to mean that temperatures were warmer on that day than on the same date throughout a weather station's history. As time passes, the number of record high and low temperatures will diminish. This is because as the years roll on and records accumulate, it becomes increasingly difficult to break a record. A new paper (Meehle 2009, see press release) examines the record highs and lows since 1950. Figure 1 shows the number of record high temperatures (red dots) and record low temperatures (blue dots). If temperatures weren't warming, we would expect the number of record highs and lows to be roughly equal. Instead, the highs and lows diverge over time with gradually more record highs than lows.
To examine this further, the ratio of record highs versus record lows were calculated for each year. Figure 2 shows the yearly ratio as black dots. The solid green line is the smoothed trend. During a period of global cooling in the 1960s, there were more record lows than highs. However, when the global warming period began in the 1970s, the ratio of highs to lows began to increase. Over the last decade, daily record high temperatures occurred twice as often as record lows.
