Once cooler air presses into the northeastern United States during Friday and this weekend, there are no signs of heat returning to the region through the end of May.
Following the hot weather through Thursday, some people will be trading shorts and short sleeves for jackets and long-sleeve attire as they have done so often this spring. A few may have to tap the thermostat to turn on the furnace for a few hours.
The leading edge of cooler air will be marked by showers and locally gusty thunderstorms from late Thursday into Friday.
Heat will get hacked away from north to south in the Northeast as the week draws to a close.
Temperatures will be slashed by 20 to 50 degrees Fahrenheit from the peak of the daytime heat through Thursday to the bottom of the nighttime chill this weekend and next week.
In Boston, daytime highs will be slashed 30 degrees from a high in the middle 90s on Thursday to a high in the lower 60s on Saturday. Highs in New York City will be slashed by 20 to 30 degrees during the period.
“An east to northeast breeze and/or cloud cover will add to the dramatic cooldown along much of the Interstate-95 corridor and the immediate coastal areas,” according to AccuWeather Chief Meteorologist Elliot Abrams.
These conditions can result in AccuWeather RealFeel® Temperatures 5 to 8 degrees lower than the actual temperature during the daytime.
Even areas as far south as Maryland and Virginia can expect a significant change.
In Washington, D.C., a heat wave to end the week will be followed by multiple nights with lows in the upper 50s and some days with highs in the 70s this weekend into next week.
“In the Ohio Valley, from Pittsburgh to Cincinnati and Indianapolis, the main thrust of the cooldown will be delayed until early next week,” according to AccuWeather Long-Range Meteorologist Max Vido.
