Rain, Rain Go Away? Probably Not Entirely Until Another Day.

Madison had one big downpour today and may get another one, the National Weather Service says. The next one might be accompanied by thunder and lightning, according to the NWS.

So, if you've been waiting for the weather to clear to head out to the polls to , you might want to reconsider and head out now before it gets worse. It might not clear up entirely for another day or so. And, if it does clear up, and you've already discharged your civic obligation to vote, then you can go for a walk or do something else outside.

When you do head out, drive carefully, there is minor local flooding on some roads and on parts of the highway. And there is a flood advisory in effect, according to the National Weather Service. 

"Rainfall rates of up to one inch in one hour is possible with these storms. Excessive runoff  ... will cause flooding of urban areas, highways, streets and underpasses as well as other drainage areas and low-lying spots," the NWS said. "Do not drive your vehicle into areas where the wather covers the roadway. Most flooding deaths occur in automobiles. Turn around and find another route."

Polls are open until 8 p.m. Surf Club in the south end of town and Brown Middle School in the north.
