Planning to travel today or this week? Here’s what could impact your route – and what you should do.
- Strong to high winds across Montana, Wyoming, and the northern Plains today. Hurricane-force wind gusts possible in parts of Montana.
- Severe thunderstorms with hail and severe wind gusts expected today into tonight across Kansas into western Texas.
- Severe storms with large to very large hail and severe wind gusts will be possible Friday afternoon and evening in parts of the central Plains and lower to mid Missouri Valley.
What this means for your trip
- Delaying or adjusting departure times may be the safest option across Montana, Wyoming, and the northern Plains where strong winds create crosswind problems for RVs and trailers. Today is the windiest day. Conditions start to improve on Friday and winds decrease significantly by Saturday.
- Severe storm corridors from the High Plains into the Midwest favor avoiding afternoon and evening travel windows where hail, damaging winds, or tornadoes are possible. Significant severe thunderstorms are possible this coming weekend into Monday.
- Fog near southeast Georgia and northeast Florida may slow morning travel and reduce visibility on coastal and northeast Florida routes.
