Time to hit the road again, this time on a 3 day excursion through the heart of Appalachia. The trip will cover 1510 miles and will be at a pace of 64.5mph, or 516 miles a day. The drive should be a scenic one. Will it also be a wet one?
DAY ONE (Sunday)
The beginning of our travels on Sunday won’t be much problem at all, really. High pressure developing across the mid Atlantic will squash any remnant showers by the time we hit the road from Barnstable. It will be rainier today in the Appalachians, but we won’t have to deal with any of that activity. Just know that it will be warm and humid, but free of precipitation throughout our day on Sunday. Expect our day to end in Martinsville in eastern West Virginia.
DAY TWO (Monday)
Precipitation will be mostly nonexistent during our Labor Day travels as well. The drive through the two Virginia should be dry, however by mid afternoon when we cross into eastern Tennessee, some clouds will begin to crowd our horizon. The biggest threat will be from isolated orographic thunderstorm activity, which means that the best chance for rain will be at the southern exposures of the highest terrain of far eastern Tennessee. I think the best threat for rain will be between Kingsport and Morristown, and again in the southern suburbs of Knoxville, but high clouds could squeeze out a drop anywhere through the region. We will make a sharp turn to the west and end up in Crossville, Tennessee to finish the day.
DAY THREE (Tuesday)
The shower activity won’t really be a problem anywhere along our route outside of the easternmost part of Tennessee. Expect things to clear out by the time we have passed through Cookesville, with generally sunny conditions all the way through the remainder of Tennessee. The NAM suggests that rain may be spilling into Arkansas by Tuesday afternoon associated with a wave emerging from the Upper Midwest, though the GFS still has this energy and resultant moisture as far north as Iowa. The NAM is at the end of it’s forecast period by Tuesday night, and I suspect it’s a bit scurrilous. Let’s just say that it will probably be mostly cloudy when we arrive in Pine BLuff, but probably not raining.
