Springlike warmth will pour from the Plains to the East before another winter storm unfolds at midweek.
After dramatically warmer air spread onto the Plains on Sunday, the rest of the eastern third of the U.S. will turn mild through Tuesday.
Highs soared to 80 degrees in St. Louis, Mo., and the 70s in Raleigh, N.C., on Monday as the warmth expanded eastward.
Temperatures returned to the 50s in New York City and Philadelphia on Monday afternoon, but Tuesday will prove to be the mid-Atlantic's warmest day of the week.
New York City will reach the low 60s, while Washington, D.C., climbs into the low to middle 70s on Tuesday.
Throughout the Midwest and East, the greatest amount of warming--in regards to departures from normal--will occur in the vicinity of I-80 and points southward.
Temperatures will return to normal or rise a few degrees above normal for a day or two across places to the north. In most of these areas, temperatures will dip below freezing at night, causing any wet areas from continued melting snow to turn slick.
Despite this taste of spring, winter does not appear to be willing to fully release its grip on the nation just yet. Colder air is destined to erase the warmup by late in the week.
Along the leading edge of this next cold blast, AccuWeather.com meteorologists continue to closely monitor a storm that will track from the Northwest and Rockies to the Northeast.
The storm will produce widespread substantial snow with the threat currently greatest from Chicago to northern New England from Tuesday night through Thursday.
