Charleston, West Virginia – Sweltering conditions are set to grip West Virginia starting Sunday, with heat index values in the lowlands climbing to 105°F and offering little relief overnight.
According to the National Weather Service in Charleston, high pressure will lock in dry, stable air today before a surge of heat and humidity builds this weekend. From Sunday through at least midweek, lowland areas will feel oppressive, with actual highs in the mid to upper 90s and muggy nights that keep conditions dangerously warm around the clock.
Daytime highs in the mountains will reach into the low 90s, especially Monday and Tuesday, compounding the heat risk for outdoor workers and vulnerable groups. The risk of heat-related illness is elevated due to prolonged exposure and minimal overnight cooling. Residents are urged to avoid strenuous activities during peak afternoon hours, hydrate frequently, and rest in air-conditioned or shaded areas.
While isolated thunderstorms could return mid-to-late next week, the sustained heat may strain energy usage and public health systems.
Dangerously high heat indices remain possible through at least Tuesday. Additional advisories could follow if the pattern persists.
