We are off on a heck of a Memorial Day road trip. It’s going to take us 4 days to get to York, which is 1905 miles from Billings. The rapid pace of Montana will blend with the glacial Pennsylvanian speed limits, and we will have an average rate of 64.1mph… Looks like those pokey speeds in the east will win out. This means our first three days (the 4th will be shorter) will see us cover 513 miles. That’s not what we are accustomed to out west, but then, we aren’t spending a lot of time out west. Tally ho!
We’re going to be getting out of Billings just in time in the morning. A sharp upper level trough will aid in the development of a low over the northern Rockies tomorrow morning, and it will begin to kick up a few showers and thunderstorms over eastern Montana, advancing into western South Dakota as the afternoon rolls on. We will outpace the wet weather, however, reaching about Rapid City by the time the convection begins, and that convection won’t reach Rapid City until we are tucked into our beds or sleeping bags in Reliance, South Dakota, which lies just west of the Missouri.
Our second day on the road won’t be as fortunate, with rain overtaking us as we sleep in South Dakota, and won’t be too far away from us as we drive through Minnesota and Wisconsin. It doesn’t appear like thunderstorms are going to be too awful as we drive west, but this time of year, the threat is always there for a heavy storm. The best chance for that will be just as we start and as far east as southwestern Minnesota, but as we make our way towards Illinois, I think we will be fine. We will arrive in Marengo, Illinois, just before we arrive in Chicago.
the third day om the car, Saturday, will once again begin wet. Northern Illinois will have a few morning showers, but the entire system is going to be shunted north as we drive. There may be some afternoon thunderstorms in western Pennsylvania, but the drive through Indiana and Ohio will be fine. Warm and humid, but fine. Our day will end around Pittsburgh with an isolated shower cropping up in the high country of Pennsylvania
Finally, a day without worry! Hot, humid, wonderful Memorial Weekend weather will accompany us through Pennsylvania. Expect no problems as we thunder on into York in the early afternoon on Sunday.
