Brief surge of mild air to pour into northeastern US this week

Topic driven playlist

After a cool start to the week across the northeastern U.S., milder air will settle in across the region through Thursday.

The change to cooler weather was especially noticeable across interior sections of the Northeast.

By Wednesday, places like Buffalo and Elmira, New York; Pittsburgh, Pennsylvania; and Morgantown, West Virginia, will experience highs in the 70s again.

Evening temperatures will rise as well. Many locations from northern New England to the northern Virginias dipped into the 20s and 30s early Tuesday morning. It will not be as chilly on Tuesday night and low temperatures will generally be in the 30s and 40s.

On Thursday, high temperatures will reach into the low 70s in Washington, D.C.; Philadelphia; New York City; Hartford, Connecticut; and Providence, Rhode Island.

It will still be cool enough during the evening and morning hours to warrant a jacket or sweater. It will be warm enough during the afternoon that most people will be comfortable with short sleeves during outdoor activities.

This warmup will arrive ahead of a cold front that will move through the Northeast on Thursday and bring showers to the region.

While the rain is not expected to be heavy, wet roads can slow travel times.

The rain will be welcome to an area that is in the midst of a drought. However, this front will not produce rainfall amounts that are needed to put a dent in the drought.

This front will bring another shot of cool air in its wake on Friday. Cool air will then continue to settle into the Northeast.

"There will be cold fronts leading in the cool air masses but the bulk of these will have little rainfall as most upper-level energy lifts into southeast Canada," AccuWeather Long-Range Meteorologist Jack Boston said.

Boston added that high pressure areas will move into the northeastern U.S. from the west and northwest behind each front. Overall, these will leave daytime highs near normal, but nights may average below normal.

For those looking to venture out this weekend to check out the fall foliage, the Northeast will be under the influence of one of these areas of high pressure. This will promote dry, sunny and seasonably cool conditions.
