Northeastern US warmup to continue into Monday as wet weather returns
A big upswing in temperatures is underway in the northeastern United States into Monday.
Temperatures into early this week will be the highest they have been since the last day or two of March.
"Temperatures in the mid-Atlantic and parts of the Northeast will average 6-12 degrees above normal through at least Monday," AccuWeather Lead Long-Range Meteorologist Paul Pastelok said.
Temperatures may climb high enough in parts of the Southeast and southern mid-Atlantic that cooling demands will increase.
Following widespread highs in the 60s and lower 70s to end the weekend, some areas will get even warmer at the start of the week.
"While temperatures may be trimmed around Boston, even warmer weather is on tap for the mid-Atlantic on Monday," according to AccuWeather Senior Meteorologist Kristina Pydynowski.
"Highs well into the 70s can be anticipated in nearly every community across the mid-Atlantic with temperatures in Washington, D.C., and Baltimore cracking the 80-degree mark," she added.

The spring air will provide an ideal setting for outdoor barbecues and cookouts, as well as other outdoor activities such as hiking, biking, fishing and golfing.
However, some areas will have to dodge wet weather.
A quick-moving storm system will bring showers and even a few thunderstorms back to the mid-Atlantic on Sunday night and Monday.
There is the potential for storms to pulse to localized severe levels in portions of the Delmarva Peninsula and into southern Virginia and the Carolinas.
By the time the rain reaches northern New England, it will change over to snow and sleet as the warmth will get cut off before reaching Vermont, New Hampshire and Maine.
A broad swath of 6 inches or more of snow is expected to target Maine, including around Bangor and Caribou.
While several inches of snow may fall across parts of Maine on Monday with steadier rain in southern New England, showers and storms should be more isolated in nature across the mid-Atlantic and only temporarily dampen outdoor plans.
The warmth should hang on across the mid-Atlantic into Tuesday before more seasonably cool weather returns by midweek.
No more long-lasting bouts of chilly air are expected to reach the mid-Atlantic this spring, although it will take until early May for any meaningful warmth to reach northern New England.
