As meteorological summer begins, the Eastern US will experience cooler-than-average temperatures due to a surge of cold air from Canada and Greenland. This pattern may lead to fewer extreme heat days and increased flood risks in drought-stricken areas, while the West anticipates above-average heat and potential drought conditions.
- 01Cooler temperatures in the Northeast and Mid-Atlantic will keep daytime highs in the 60s and 70s, with nighttime lows in the 40s and 50s.
- 02The cooler start may reduce the number of 90-degree days and air conditioner usage in the Northeast this summer.
- 03The Pacific Northwest is forecasted to experience above-normal temperatures, with cities like Seattle and Portland likely to see more frequent hot days.
- 04Flood risks are elevated in the Southeast due to potential downpours, particularly in cities such as New Orleans and Atlanta.
- 05Marine heat waves in the Gulf of Mexico and the Pacific could significantly influence summer weather patterns, increasing storm intensity and precipitation.

As the transition to meteorological summer occurs, the Eastern United States is set to experience an unseasonably cool start, with temperatures expected to remain in the 60s and 70s during the day and drop to the 40s and 50s at night. This cooler air is moving southward from Canada and Greenland, potentially leading to fewer 90-degree days and less reliance on air conditioning. In contrast, the Pacific Northwest is predicted to see above-average temperatures, particularly in cities like Seattle and Portland. The Southeast, meanwhile, faces increased flood risks due to anticipated heavy downpours, especially in drought-affected areas. Marine heat waves in both the Gulf of Mexico and the Pacific Ocean are expected to significantly shape summer weather patterns, potentially enhancing storm activity and precipitation levels. This unique weather scenario is linked to the developing El Niño phenomenon, which is characterized by warmer ocean temperatures and could lead to an active hurricane season.
