| Rain shower during late afternoon lasted only 10-15 minutes but had caused minor street flooding by the time it ended with water running down the street but did not get over the curb. Some pea sized hail mixed in that came after rain started. Sun was out at least part of the time during the event as the rain came down from the back (west) end of the cloud and the sun was farther to the west, if that makes sense. I did not send in an alert to NWS |
