NAM projects Up to 2.4'' to Fall in Chicago Tonight

The NAM is projecting up to 2.4 inches of rain to fall in a very narrow strip which includes Chicago in a 24 hour period. This is an extremely heavy amount of rain in such a short period- something that could cause a flooding event.
Because this is a very intense amount of rain, we have looked into the possibility of a heavy rain cell occurring over this area due to its locality.
It does appear that from tonight into the 10 am period tomorrow morning may have several yellow cells appearing on radar over the same area in a very eerie coincidence. Yellow is defined as moderate rain on radar reflectivity.
We will closely watch this solution this evening to keep you in the know.
