My, if this isn’t an interesting drive, one not often dreamt up in a place like this. We are going from Idaho to Washington, though that just requires a quick river crossing. What will be more impressive is the 6 hours it takes to cross the state. In total, the one day journey will cover almost exactly 400 miles at a pace of a mere 59.4mph. Hitch the wagons and tally-ho!
A developing low over the Yakima valley will make the typically dry eastern Washington area a little damper than is usual. On Memorial Day itself, much of the heavy rain will be near Spokane, so some of that may filter south towards Colfax before we turn east. It’s always a little turbulent when driving through coastal ranges when there is a system in the area, so grab the steering while tight around the Cascades. There will be some overcast, and maybe a spit of rain in Bellingham.
