Harrisburg, Pa. – Unseasonably hot weather is expected to grip a wide swath of the eastern U.S. beginning June 22, with temperatures climbing 10 to 15 degrees above normal from Pennsylvania to South Carolina.
According to the National Weather Service, a strong high-pressure ridge will raise temperatures across the region for the last week of June. The probability of above-normal temperatures is 50% to 60% for most of the Mid-Atlantic and lower Ohio Valley, including central Indiana, West Virginia, Virginia, and the Carolinas.
Normal highs for this time of year are in the upper 70s to low 80s, but next week could bring highs in the mid-90s, especially in inland cities like Roanoke, Raleigh, and Harrisburg. Overnight lows may stay in the 70s, limiting relief and increasing heat stress, particularly for vulnerable populations.
Residents are urged to limit outdoor activity during peak heat hours, stay hydrated, and check on elderly neighbors and pets. Cities like Charleston, WV, and Greensboro, NC, could issue local heat advisories as conditions develop.
This early summer heat wave could stress power grids and lead to elevated cooling demands. Updates will follow if heat warnings or advisories are issued.
