Temperature Roller Coaster Will Take U.S. Northeast for a Ride

  • Enjoy the warmth in the East while you can, forecasters say
  • April could be starting with a chill from Minnesota to Georgia

Winter’s grip is reluctantly giving way to spring from New York and Boston to Toronto and Chicago.

From Wednesday to Friday, temperatures in Central Park will swing from the mid-30s to near 70 degrees Fahrenheit (21 Celsius) as winds from the south bring warm air and a tantalizing taste of spring, according to the National Weather Service.

It won’t last. The Arctic’s frigid hand will reach down Saturday from Canada and send temperatures across the eastern U.S. tumbling as much as 30 degrees below normal. Upstate New York and most of New England have at least an 80 percent chance of colder-than-normal readings through the first full week of April, according to the U.S. Climate Prediction Center in College Park, Maryland.

“The next few days will be pleasant, so if you get an opportunity, get out and enjoy it,” said Dave Hamrick, a meteorologist with the U.S. Weather Prediction Center in College Park. “By the time this weekend will get here, there will be a much more pronounced change.”

The chance for cold also stretches from Minnesota to Georgia, although the odds aren’t as high, according to the Climate Prediction Center.

This week’s temperature roller coaster is partly the result of the storm that dropped upwards of a foot of snow across Wyoming and threatened severe thunderstorms across the South, said Rob Carolan, owner of Hometown Forecast Services Inc. in Nashua, New Hampshire. As that system tracks up into Canada, colder air will be drawn south, producing the “extreme” changes.

Boston Snow

The cold will linger. Lows in New York, Philadelphia, Chicago and Washington are forecast to reach into the 30s, Tuesday, according to MDA Weather Services in Gaithersburg, Maryland. Boston could fall to the 20s and Toronto to 17, according to Environment and Climate Change Canada.

Computer-forecast models are hinting there could even be snow in the air for Boston and southern New England, Carolan said.

A little something to look forward to.
