A backdoor cold front is expected to cut across the Northeast late this week and into the weekend, bringing quick relief to record heat in the region.
"At the beginning of this week, this cold front looked kind of wimpy," FOX Weather meteorologist Britta Merwin said. "But now it's looking a little more substantial, a little more of a temp drop. For several cities, there could be a 20-degree temperature drop for a few of you."
The FOX Forecast Center said highs will soar Friday, easily topping off in the 80s and 90s.
FOX 29 in Philadelphia reports dozens of public schools in the city aren't equipped with air conditioning or have inadequate units. Nearly 100 of those schools will hold a 2-hour early dismissal Friday due to forecast extreme heat.
Temperatures in Philadelphia are slated to exceed 90 degrees on Friday, with uninterrupted sunshine that could make temperatures feel even warmer.
The district warned that excessive heat could cause heat-related illness, FOX 29 reports. They advised students during the upcoming summer months to stay hydrated and dress in light-colored clothes.
The 96-degree high in Burlington, Vermont, on Thursday not only broke the record of 90 degrees in 2011, but it was the warmest it has been there since June 7, 2021.
The FOX Forecast Center said the city has not seen a temperature above 96 degrees since August 2018 when it reached 97 degrees. It was also the earliest 96-degree day ever recorded since 1884.
Heat bakes the Great Lakes, Northern Plains too
Elsewhere, high temperatures will continue to trend 10 to 20 degrees above average from the Northeast to the Great Lakes and Northern Plains as upper-level ridging hovers over the region.
The heat will be spreading from the north, whereas during the summer we typically see record heat due to impressive surges of warm and moist air from the south.
Temperatures come crashing down over the weekend
The heat will be quickly replaced with highs in the 50s and 60s this weekend, as a backdoor cold front pushes south from Canada into New England later on Friday.
The National Weather Service said the front will bring a surge of cool and damp air into the region, along with an expanding area of showers and embedded thunderstorms across New York and central New England into Saturday morning.
On Sunday, temperatures in New York City and Washington, D.C. will drop to the 70s, while Boston, Bangor, Maine, and other areas in the Northeast will see temperatures plunge to the 50s.
