ST. LOUIS — Statistically, it's the wettest month of the year in St. Louis. That usually means we always have some sort of rain chances around Memorial Day weekend. Depending on when this weekend falls, it can also be a little cooler. We have entered the time of the year when, by looking at the standard phone app, it looks like it's going to rain every day, and probably every single second of every day. I can assure you, that's not the case.
