We are transitioning into a wetter pattern the next several days

Michiana is accustomed to ever changing weather patterns through the seasons. But do you actually know why that is? Or why we see long stretches of dry/wet weather? 

Weather systems around the world are primarily driven by the jet stream. Storm systems develop and ride the jet from west to east here in the northern hemisphere. When we see long stretches of dry weather here in Michiana, that typically means our jet stream is further to the north, and most of the Midwest is dominated by high pressure. This is when we primarily deal with sunny, dry, and somewhat humid weather, just like what we have seen this past week.

As we head into the weekend and next week, we are tracking more of a wet pattern for us here in Michiana. This means that our jet stream sinks further to the south and positions itself over our area. Now round after round of low pressure will travel along the jet with its associated fronts. These fronts will interact with lots of moisture that moves in out of the south to provide daily rain chances.
