This week's scorching heat will be followed by torrential rains and a significant cool front, leaving some to wonder when summer will end and what will fall 2025 feel like? Here's what AccuWeather and the Old Farmer's Almanac have to say about autumn.
Accuweather meteorologists are warning of torrential downpours, strong thunderstorms and life-threatening flash flooding across the Northeast on July 31, including Delaware. This follows blazing high temperatures and humidity earlier this week and also comes ahead of a forecast that will bring noticeably cooler and less humid air for a change.
An overall warmer-than-average fall season has been predicted by the Old Farmer's Almanac for 2025 for the United States and Delaware.
Along the Atlantic Corridor, average temperatures will be 70 degrees in September and 55 degrees in October, according to the Almanac. Expected precipitation levels will be three inches in September and four inches in October.
"Cooler overall with scattered showers, brief warmth mid-month, and heavy rain followed by a cool finish," was the forecast description on the Almanac's website.
Cool temperatures and below-average rainfalls could also translate into beautiful fall foliage in the Northeast.
