After a brief break from high humidity, oppressive summer heat is returning to much of the eastern United States this week.
Forecasters say temperatures will climb into the upper 80s and 90s across major cities from Washington, D.C., to Boston, with heat index values expected to push conditions into uncomfortable territory. The return of high humidity levels will make it feel hotter than actual readings, particularly during the afternoon and evening hours.
The heat resurgence follows several days of more comfortable weather brought by a passing cold front last week, which lowered humidity and provided a temporary break from the sticky conditions that have dominated much of July. Meteorologists warn that the renewed heat dome settling over the East could linger through the weekend, raising concerns about heat-related health risks.
Officials are urging residents, especially the elderly and those with underlying health conditions, to take precautions by staying hydrated, limiting outdoor activity during peak heat, and checking on neighbors who may be vulnerable. Cooling centers are expected to open in several metropolitan areas if temperatures climb further.
Nighttime lows will also remain elevated, offering little relief after sunset. Combined with the increase in humidity, the hot and stagnant conditions could also worsen air quality in urban areas, prompting potential ozone alerts.
While a few scattered thunderstorms may provide localized cooling in parts of the Mid-Atlantic and Northeast, most areas are likely to experience continued warm, muggy weather into early next week.
Meteorologists advise that the current heat pattern is typical for late July but still poses risks if proper precautions are not taken. Residents are encouraged to stay aware of local forecasts and heat advisories as conditions intensify.
