Make no mistake about it. The signs are there for all to see. The Midwest is entering an unusually wet pattern that raises concerns about excessive rains and flooding for some the next 7-14 days. Let's dig in. We'll start with the MJO. By following the dotted green lines you can see the long range forecast of the EURO MJO it's projected to spend much of the next 3 weeks in phases 1 and 2.

In fact all of the stations below are currently experiencing one of the top 10 wettest. That's quite a bit or real estate. These stations will have their all-time wettest summer.
