I-70 Weather

When planning a drive along I-70, keeping a close eye on I‑70 Weather can mean the difference between smooth sailing and stuck in a snowdrift. Stretching just over 2,150 miles from Cove Fort, Utah, to Baltimore, Maryland, I‑70 traverses ten states and a wide range of climates. In Colorado’s high country, sudden snow squalls and subzero temperatures around the Eisenhower Tunnel are common even in spring, while the wide-open Kansas plains can spawn severe thunderstorms, hail, and summer dust storms. Further east, you’ll encounter humid heat and pop‑up storms across Missouri and Illinois, and the rolling Appalachian foothills bring their own winter ice and fog challenges.
