With support from the upper levels of the atmosphere, deep low pressure will continue growing to our Southwest throught day. As it tracks closer, that storm center will drag a massive amount of Gulf moisture Northward. Look for showers and some thunderstorms to develop during the day today. That precipitation really kicks up in intensity overnight tonight, into Thursday and Thursday night, and lingering into Friday. During this period many locations could pick up between 2 and 4 inches of rain. With that much on top of all the liquid from last week we're going to need to be on guard for potential serious flooding. It's worth noting that the record for April's monthly rainfall in Milwaukee is 7.31 inches back in 1973. We've already picked up about 4.27 inches. If this pattern persists, this could be a record setting month for precipitation.
Have a great Wednesday and get ready for the rain!
