Your RV Weather Road Trip Forecast for Tuesday May 12, 2026

Planning to travel today or this week? Here’s what could impact your route – and what you should do.

Strong winds across southern Oregon and eastern California today. Widespread strong winds across the west north of I-40 on Wednesday.
Blowing Dust hazard for central Illinois this afternoon and evening.
Isolated severe thunderstorms possible today across the Florida Peninsula and parts of the Midwest & Great Lakes.

What this means for your trip

Consider avoiding driving in the High Winds from the Great Basin, into the Northwest and Northern Rockies, and across the northern Plains, on Wednesday and Thursday.
Avoid central Illinois dust-prone areas during the midday-to-evening window. Sudden visibility drops on the Interstates can be extremely dangerous.
For eastern routes, fog this morning (Mid-Atlantic), then scattered severe storms later today (mostly Florida) may bound your stress-free driving time. Good driving conditions today though from San Antonio to Boston.
