The overall trend will be towards cooler weather, with an increasing chance of showers and thunderstorms Wednesday. In fact, it is the best chance of measurable rain we have seen for a while.

Drier air will be moving into the region today, so evening thunderstorms will be less likely. A few isolated storms could still pop up especially in areas to the East and South of Billings. High temperatures will be mainly in the upper 70s to lower 80s today and again tomorrow.

A weather system moves through the region on Wednesday, increasing the chance of showers and thunderstorms. With cooler temperatures and less wind, the chance of getting some moisture to seep into the ground is better than it has been recently.
