Charleston, West Virginia – Drivers along major Appalachian corridors could face water-covered roads and rapid visibility drops within the first full week of April as repeated rain systems move through the mountain region.
According to the National Weather Service Climate Prediction Center, the Appalachian region from Tennessee through West Virginia into western Pennsylvania sits in a 50–60% probability zone for above-normal precipitation through mid-April, with temperatures trending 40–60% above average. This pattern supports frequent rainfall enhanced by unseasonable warmth.
In eastern Tennessee, including Knoxville, and across western North Carolina, rain could create slick conditions along I-40 and I-26. Through eastern Kentucky and southern West Virginia, including Charleston and Beckley, runoff in steep terrain may quickly lead to rising creeks and localized flooding. Farther north into western Pennsylvania, Pittsburgh commuters along I-79 and I-76 could encounter pooling water during peak travel times.
Afternoon highs are expected to climb into the upper 70s and mid-80s across much of the region, increasing humidity and allowing storms to produce heavier bursts of rain. Mountain geography will further enhance rainfall rates in some locations.
Residents should monitor stream levels, clear drainage areas, and avoid driving through flooded roadways, especially in valleys and low crossings. Charge devices ahead of stronger rain bands that could trigger isolated outages.
This active and humid pattern is expected to persist through mid-April, with additional alerts likely as new systems develop across the Appalachians.
