Record highs were set across the Northeast on Wednesday as temperatures surged into the 80s and even the 90s. New York City even tied its record high of 90 degrees, which was set back in 2001. It’s also the earliest point in which the city has reached 90 degrees since 2010, when it happened on April 7th. Boston got close to their record high of 91 degrees with an actual high of 89 degrees, while 91 degrees set the record high in Washington, DC.

This heat will continue into Thursday and Friday as a strong upper-level ridge, coupled with a Bermuda High, continue to push warm and moist air in from the south and west. High temperatures on Thursday will range from the 60s and 70s in the Great Lakes region, Ohio Valley, and interior Northeast, to the 80s for the remainder of the region. Most of the Eastern US will experience highs in the 80 degree range, and even rise into the 90s in West Texas, the Rio Grande Valley, as well as portions of the I-95 corridor. Major cities at risk for 90+ degree heat in the Northeast on Thursday include: Portland (ME), Boston,  New York City, Philadelphia, Baltimore, and Washington, DC. Some of these cities, or surrounding areas, may experience temperatures as warm as 95 degrees. Nearly two dozen climate locations in the Northeast are forecast to either tie or break their record daily high.

Following these high temperatures, on Friday a cold front will begin to approach from the west. The combination of this frontal passage with rain and thunderstorms will keep high temperatures down in the 70s for the Great Lakes, much of the Ohio Valley, and the interior Northeast. Much of the I-95 corridor will experience highs in the 80s from southern New England, to the 90s in the Mid-Atlantic.

Beginning on the weekend, the intense heat will move offshore to the east, though temperatures will remain around 5 degrees above average in the Northeast on Saturday. This translates to actually high temperatures in the 60s and 70s for most locations. Further in the Midwest, highs will be up to 10 degrees above average and up to 25 degrees above average in the Central and Northern Plains.

On Sunday, cooler than normal temperatures will invade the Great Lakes region and interior Northeast, most of these areas will be around 5 degrees below average. The rest of the country will continue to experience above average temperatures, including the intermountain West now that the trough of low pressure has lifted off into Canada. High temperatures will be slightly above average for the East Coast ranging from 10 to 30 degrees above average for the Western and Central US.

Looking ahead to next week, a brief dip in the jet stream will bring slightly cooler than normal air to the Northeast, Ohio Valley, and Mid-Atlantic on Monday, however warmer temperatures will begin to creep back in on Tuesday. Overall, next week will feature seasonable temperatures for the East Coast while above average temperatures will dominate the Western and Central US. Another round of highly anomalous heat may return back to the Eastern US beginning next week.
