Forecast Last Updated at Wednesday, July 18, 2018 at 6:19PM
Cooler and drier high pressure has moved into the region and stays in control of the weather through Friday. The result is for a generally pleasant stretch of days until the weekend with slightly lower temperatures and lots of sunshine. The hiccup is a modest southeasterly flow which could aid in the development of a stray pop-up shower Thursday and Friday afternoon.

In most regards the forecast is pretty easy right on through the middle of next week. That doesn't mean it's boring, the devil is in the details. First up, high pressure is in control through Friday afternoon. Dewpoints come down as a result so it will be less muggy, but they don't come down enough to preclude the mention of a stray PM shower Thursday or Friday. A southeasterly upslope flow makes that mention necessary, but most of us stay dry.
This weekend an upper level low moves south from the Upper Midwest and becomes parked over the Ohio Valley and southern Appalachians. Scattered showers and thundershowers become the new normal beginning Saturday and persist through the first half of next week as the upper low forces a pattern shift to a more active East Coast upper trough configuration. On paper July is the wettest month of the year (just barely) and it hasn't played out that way this season. Now it's time to catch-up.
It's tough to say which day is the wettest and get into the details of timing. However, showers won't be limited to just the afternoon or evening hours Saturday and Sunday as the upper low tightens and gets closer. We think as the low opens up into an upper level wave by Monday most of the action becomes anchored to daytime heating lending to mainly PM activity. The daily dose of showers won't slow down until the end of next week.
