The arctic blast that gripped much of the central and eastern U.S. last week and into the weekend is on its way out and a significant warm-up is on the way to much of the eastern half of the country.
A large warm-up is expected to thaw out much of Midwest to Northeast early this week.
The warm front that lifted through Chicago, Indianapolis, Detroit and Pittsburgh, bringing an ice storm over the weekend, will usher in the milder air.
Temperatures will rise into the upper 40s in Chicago and 50s in Indianapolis by Monday afternoon.
Though some rain and fog may linger through the day on Monday, the real mild weather is expected on Tuesday as highs approach the mid-50s in the Windy City and near-record levels in Cincinnati and Indianapolis.
Farther to the East, the aforementioned warm front moved through Washington, D.C., and Philadelphia on Monday morning. Some snow, sleet and freezing rain fell at the onset, before a changeover to rain in these cities.
The significant warm-up will take until Tuesday to get into the Carolinas and mid-Atlantic, when temperatures rise into the 60s all the way northward to the Mason/Dixon line.
The 70s will be common as far north as Fayetteville, N.C., on Tuesday.
Even residents of central and northern New England who haven't experienced a 32-degree temperature in over a week will turn much milder Tuesday into Wednesday.
High temperatures in NYC, Boston, and Albany will rise into the upper 50s and near 60 degrees on Wednesday.
However, similarly to areas farther south, this warm-up will come after another period of frozen precipitation. Some icing will be possible on Monday across central and northern New England as the warm front lifts through, and that could lead to significant travel problems during the morning commute.
The warm weather will end across the Midwest Tuesday night as a potent cold front moves through with one more warm day expected in the East on Wednesday before the cooler air overtakes the region by Thursday.
The big clashes in air masses will lead to other problems. AccuWeather.com Meteorologists are also concerned about a potential severe weather outbreak beginning late Tuesday in the lower Mississippi Valley and continuing through Wednesday in the Southeast.
A storm will bring snow and ice that will lead to slippery travel along a 1,500-mile swath from northern Arkansas and Georgia to Maine early next week.
Spring of 2016 could rank in the top 10 warmest on record for Canada.
