Stay hydrated, seek AC, limit activities
This prolonged period of extreme heat can lead to heatstroke, dehydration, and other heat-related illnesses, particularly among vulnerable populations such as the elderly, children, and those with chronic health conditions.

Cold front bringing cooler, drier air
Fortunately, relief is on the horizon. A cold front is expected to move through the region by the weekend, bringing cooler and drier air. This weather shift will cause temperatures to drop 5–20 degrees below normal across much of the East, providing much-needed respite from the oppressive heat.
Take precautions, heed warnings, enjoy respite
Weather forecasters advise residents to remain vigilant and continue to take precautions until the cold front arrives. Stay informed about local weather updates and heed any warnings issued by local authorities. Once the cold front passes, enjoy the cooler temperatures and take advantage of outdoor activities, but remember to stay prepared for potential changes in weather conditions.
