Northeast Temperatures About to Plunge After Record Heat Wave

The summerlike heat that gripped the Northeast to start the week is going to disappear in an instant. The roller coaster weather pattern that has marked the spring season will take another dramatic dip on Wednesday, ushering in noticeably cooler temperatures to some of the nation's most populated cities. Read on for a look at when and where the temperatures will take a nosedive, as well as when they will recover.

Cooler Canadian Air Set to Replace Northeast Heat Wave

Another dramatic cooldown is heading to the Northeast. The change in the weather will feel even more pronounced on the heels of the record-breaking heat that was the story for the beginning of the week. A mass of cooler and less humid air is going to sweep in from Canada and the Midwest beginning on Wednesday, replacing the steamy conditions.

The hot and humid weather will be confined to the immediate Atlantic seaboard on Wednesday. Meanwhile, the cooler air mass will begin to push into the Appalachians.

Residents will need to swap out their shorts and tank tops for jackets and pants as the week progresses. While the weather pattern as of late may feel chaotic, this is quite common during the month of May when spring and summer duke it out for supremacy.

Communities that saw temperatures in the low 90s to start the work week will fall into the 70s for highs on Wednesday. By Thursday, the Northeast should expect widespread highs in the 60s. This chill will hang on through the early part of the holiday weekend.

While it will certainly feel chillier after the early-week heat, the good news is that there is no widespread threat of frost or freeze conditions. The exception to this threat will be in the northern reaches of New England and upstate New York. The average last frost date of the season is not until early June in this part of the country. The rest of the Northeast should prepare for overnight lows that dip down into the upper 30s to the upper 50s over the next few days.
