Charleston, WV – A migrating heat dome is set to push temperatures into the mid to upper 80s across West Virginia within days, bringing early-season heat and repeated storm chances that could disrupt travel through the first full week of April.
According to the National Weather Service Climate Prediction Center, a 70 to 80 percent probability of above-normal temperatures will dominate West Virginia from April 3 through April 9 as strong high pressure builds across the Southeast and Mid-Atlantic. Highs in Charleston, Huntington, and Morgantown are expected to run 10 to 20 degrees above seasonal averages, with some locations nearing 90 degrees. Overnight lows will remain mild, limiting relief.
West Virginia sits along the northern edge of the heat dome, where warm, humid air will interact with passing disturbances to fuel repeated rounds of showers and thunderstorms.
Rain chances increase statewide, especially during afternoon and evening hours. Heavier downpours could impact major corridors including I-64, I-77, and I-79, leading to reduced visibility and water-covered roads during peak travel times, particularly in mountainous terrain.
Residents are urged to stay hydrated, limit strenuous outdoor activity during peak heat, and avoid driving through flooded roadways.
This pattern is expected to persist through April 3–9, with additional advisories likely as storm timing and rainfall totals become more defined.
