We’re continuing to track downpours and embedded thunder moving into southern New England. In addition to localized street flooding and minor river flooding, there could be some strong to severe thunderstorms.
New this afternoon:
The Storm Prediction Center has placed RI and southeastern MA under a marginal risk for severe thunderstorms.
The timing looks to be between 4pm-9pm. Here’s the RPM Simulated radar around the time of the evening commute.
The main threats with any storms today would be:
- Torrential Downpours
- Damaging Wind Gusts
- Dangerous Lightning
- Brief Tornado (though unlikely, it’s not impossible).
As for the flood threat… for most of us, the main issue will be heavy rain leading to brief and localized street flooding. Once the rain tapers off, the flooding quickly subsides.
For those near the Pawtuxet, Pawcatuck, Wood and Taunton Rivers, minor flooding is possible. The river water levels will continue to rise as run-off drains into the streams and tributaries. That means the rivers will likely crest after the rain has ended. In fact, the Pawtuxet is forecast to crest early Friday morning. At this point, significant river flooding is not expected.
As we head past 8pm, the rain will taper off, with lingering fog into the early part of tonight.
