Up, up and away once again. We won’t be covering the entirety of the United States with this trip, merely stopping 2/3 the way, in Kankakee. It will take us 4 days to cover 2125 miles, which means an hourly pace of about 65mph, leading to the three leading days being through after about 520 miles, leaving the change for Tuesday. Let’s climb the mountains and make our way east.
DAY ONE (Saturday)
There is a large system moving into the northwestern United States, and San Francisco Bay will be seeing some rain and wind by the time we hit the road tomorrow. This will follow us through the Sacramento Valley, but will really be tapering off by the time we reach Sacramento itself. The Sierras look good, and we will be dry through western Nevada, There will be some mountain showers and storms, but many are focused near Salt Lake City, which is too far east for our Sunday goal. Instead, dry weather, fairly warm, to be sure, will allow us to camp in an RV or tent around Deeth, Nevada, with no fear of rough weather.
DAY TWO (Sunday)
Guidance suggests a long stream of showers from the Baja to the Canadian Prairies with little variation from this swath. Expect it to be dry through Salt Lake City, with some rain chances picking up as we climb into the mountains. The best shot at rain will be from Summit Peak, east of Salt Lake, to Rock Springs Wyoming. It will dry out quickly on the way east, before we stop in what should be a quiet Walcott, Wyoming.
DAY THREE (Monday)
Strong surface low pressure will be developing in the far northern Plains as we head east, but won’t emerge far enough into the Plains to make too much of an impact. The boundary extending from local pressure minima in Saskatchewan and eastern Colorado will run through the North Platte area, bringing some fluffier clouds, and perhaps a stray shower (which, in this part of the world could always entail some thunder as well). Anything we see will be brief, which is fantastic news, and we will press onward to York in hot, sticky late August air.
DAY FOUR (Tuesday)
Guidance isn’t 100% sure, but it definitely seems possible that the drive through Iowa will remain dry, but with temperatures warm and the atmosphere soupy, it’s entirely possible that some lifting parcels breach the cap, and there could be a stray thunderstorm throughout the Hawkeye State. Northern Illinois will be even moister, which means more instability, so don’t be surprised to see a little more stratiform rain mixed in with the thunder. There will still be more sun than rain, and generally speaking, those school buses we pass as we arrive when we get to Kankakee will be upset they spent the whole day in school.
