You’ll want to keep your umbrella handy on Wednesday.

The National Weather Service is forecasting that a first round of scattered showers and thunderstorms will occur during the morning, with the system exiting the region around 10 a.m. The meteorologists say there is the potential for some localized street flooding, but the risk is lower than previously forecast.

A second round of storms is also predicted during the afternoon, along with “summer-like temperatures and humidity,” the service said.

While the later rain and storms are expected to be more “hit or miss,” forecasters say they could be more severe.

“This afternoon, there is the possibility of scattered strong to severe thunderstorm activity, which may produce strong to damaging wind gusts,” the service said.

Other than the wet weather, meteorologists are predicting a “typical summer afternoon” with high temperatures in the mid-to-upper 80s and dew points in the low 70s.
