Lots of rain right now. I expect there to be a very quick response in the Huron River today (considering how much of a leap happened yesterday when there seemed to far less rain). If you look at the below graph of river discharge in the Huron River at Ann Arbor, you can see that over the course of a few hours of heavy"-ish" rain, there was a four-fold increase in discharge (unfortunately, I don't have the rain gage data for yesterday). I would expect that today's rain will create a discharge of over 1000 cfs (9 times greater than the median discharge of the day - of course, I do understand that a single day's anomalous weather has little impact on the median value of a series, but it is still amazing! For this reason, this calls for some expletive! OMG!!!
Also, there will be photos of people running through the rain, and (if I can figure out how to put up some short video) a clip of people trying to wade through or pursuing a futile effort to walk around a large puddle that blocks the entire pavement. (It always causes a problem when there is a lot of rain, and becomes downright deadly when the weather turns cold enough to freeze puddles into a vast plain of slippery death.)
