Thunderstorms likely this afternoon and tonight, 7/11/19

max_weisenfeld

There's a flash flood watch associated with the thunderstorms forecast for this afternoon and tonight.  Heavy rain from localized storms may cause low lying areas and poorly drained roads to flood.

Thunderstorms later this afternoon (after 3pm) through tonight may cause locally heavy downpours with areas of 1 -2 inches of rain.  This could lead to flooding and road ponding in areas that often experience flooding.

Details of the watch in the first comment below.

You should monitor later forecasts and be prepared to take action should flash flood warnings be issued.

Thank you for posting this!  I saw it just a few minutes later and was able to make a (hopefully advantageous) flight change before United sent out a notification of waived change fees, so I got in ahead of the crowd.  That being said, I am now sitting in the airport looking at the pouring rain and the new, earlier flight is also delayed.  So far, I think I'm still better off being on a delayed 3:30pm flight rather than a delayed 8:30pm flight.  We shall see.

This evening's Prospect Street walk through is advertised as rain or shine.  We shall see.

Off by 15 minutes (rain started at 2:45) but I'll take it.

FWIW, that was 1.5 inches in 45 minutes
