Seasonal Driving Considerations
The Midwest corridor of this route is susceptible to rapid weather changes. Severe thunderstorms and tornadoes are a real threat from April through June, while winter brings heavy lake-effect snow, ice storms, and dangerously low wind chill. Flat terrain means high crosswinds can affect vehicle stability year-round, especially for taller vehicles. Spring flooding can also close highway underpasses and low-lying road segments.

For medium-distance drives like this 426-mile route, consider starting in the early morning to arrive before afternoon storms develop. Check the 7-day forecast above to find a day with favorable conditions along the entire route.
Driving Strategy
A 426-mile drive from Webster Groves to Gatlinburg takes a significant part of the day. Plan at least one fuel and rest stop along the way. If your route crosses elevation changes or state lines, expect weather conditions to shift mid-trip. Monitor the segment-by-segment forecast rather than just checking destination weather. Starting early in the morning typically avoids afternoon storm development and rush-hour congestion near urban areas.
