Weekend forecast: Calming down and drying out

/ at 6:38 PM

After several days of periodic, road-flooding deluges, a break is in store for the weekend as a front pushes south of the area. While we could see a few lingering storms on Saturday, we should see a little more in the way of sunshine through broken cloud cover as well. After a mid-70s start, temperatures will head to about 90° in the afternoon. Heat indices will not be quite the factor that they have been thus far in July, either: it’ll feel around 95° or so. Certainly not cool by any objective measure, but it’s not 105°, either.

Drier air pushes into the area on Sunday, and despite highs in the low 90s once again, it’s just going to feel a lot better as dewpoints mix out to the mid-60s in the afternoon. (We’ve been dealing with mid-to-upper 70s dewpoints for the better part of several weeks now, so this will be nice!) The drier air will help promote generally sunny skies with little to no chance of any rain in the afternoon. It’ll be one of the better outdoors days in recent memory, and dewpoints in the mid-60s essentially remove the heat index from the equation.

Enjoy this, because as we depart July and head into August next week, we’re back into a pretty standard summertime pattern with warm temperatures, mid-70s dewpoints, and afternoon storms.
