Halloween Forecast: This year's trick-or-treating could be the warmest in decades for the Northeast

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

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

In Boston, temperatures could reach 80 degrees, potentially making it the second hottest Halloween on record, just shy of the 81-degree record set in 1946. The average for this time of year is about 57 degrees.

Philadelphia is expected to reach 81 degrees, which would also make it the second hottest Halloween on record, behind the 82 degrees recorded in 1946. The city's typical temperature in late October is around 61 degrees.

New York City can see highs of 75 degrees, which would rank as the sixth warmest Halloween. The all-time high of 81 degrees from 1946 still stands, while in four other years temperatures reached 76 degrees. Typically, the average temperature in New York during this period is around 59 degrees.

In Washington, DC, temperatures could reach 80 degrees, marking the third warmest Halloween holiday.

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

Strong to severe thunderstorms, including damaging winds, are possible late Thursday from Indianapolis south to Shreveport, Louisiana. Rain is also expected for western cities such as Seattle, Portland, Boise, Idaho and Redding, California on Thursday evening.

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 expected in the higher elevations of the Cascades and Olympics in the Pacific Northwest.
