This Halloween could be one of the hottest on record in parts of the Great Lakes, Northeast and Mid-Atlantic Oceans as a warm front pushes in from the Southern Plains.

Nearly 50 daily high temperature records could fall on Thursday, with temperatures rising more than 20 degrees above normal, resembling late summer conditions, rather than Halloween.

In Boston, temperatures could reach 80 degrees, which could potentially be the second hottest Halloween on record, just shy of the record high of 81 degrees set in 1946. The average for this time of year is around 57 degrees.

Philadelphia is forecast to reach a high of 81 degrees, which would also place it as the second hottest Halloween on record, behind the 82 degrees recorded in 1946. The city’s typical temperature for late October hovers around 61 degrees .

New York City could see a high of 75 degrees, which would rank as the sixth hottest Halloween. The all-time record of 81 degrees, set in 1946, still stands, while in four other years the temperature reached 76 degrees. Normally, the average temperature in New York during this period is around 59 degrees.

Washington, DC, could reach 80 degrees, making it the third hottest Halloween.

Some trick-or-treaters in other parts of the country may need a raincoat to accompany their costumes, as rain is expected on Halloween night across much of the Upper Midwest to the Ark-La-Tex region.

Strong to severe thunderstorms, including damaging winds, are possible from south of Indianapolis to Shreveport, Louisiana, late Thursday. There are also likely rain chances Thursday evening for western cities like Seattle, Portland, Boise, Idaho and Redding, California.

Others may need to add snow boots or other winter gear to their costumes. In Duluth, Minnesota, rain will turn to snow after 4 p.m., and snow is also likely in the higher elevations of the Cascades and the Olympics in the Pacific Northwest.
