After a stretch of cool, rainy weather, summer is set to arrive in full force across the eastern United States, with a significant heat wave expected to begin this weekend and persist through at least the middle of next week.
In southcentral Pennsylvania, temperatures are forecast to climb into the 90s starting Sunday, marking the region’s first heat wave of the season—and the first time this year the mercury will hit 90 degrees. The National Weather Service predicts a high of 93 degrees on Sunday, while AccuWeather.com anticipates 91 degrees on Saturday and 98 degrees on Monday.
Forecast models suggest the heat could challenge long-standing records. In York, a projected high of 97 degrees on Sunday is just one degree shy of the record set in 1988. Monday’s forecast could break the record of 96 degrees set in 1943.
High humidity will exacerbate the already extreme conditions, with heat indices potentially reaching 105 degrees. A strong ridge of high pressure will anchor itself over the region, keeping skies clear and conditions hot and dry.
With temperatures expected to remain in the 90s through the week and potentially into the following weekend, meteorologists are urging residents to take precautions. Prolonged exposure to high heat can lead to heat exhaustion or heat stroke, particularly for vulnerable populations.
To stay safe, the National Weather Service recommends staying hydrated, avoiding strenuous outdoor activity during peak heat hours, wearing light clothing, and seeking air-conditioned spaces whenever possible.
