It looks like rain chances start to increase starting Saturday with a 30% chance of rain with high temps reaching about 86 degrees. We could see an isolated shower or thunderstorm with daytime heating. For Mother’s Day the chance decreases just a hair to 20%, while the high temps will be about 86 degrees as well.

We are watching for a possible increased chance of thunderstorm activity for Monday, as we have about a 50% chance of rain that day. What we are in particular watching is the SPC now has us outlooked for a chance of severe weather for Monday (Day 5).

When outlooked on days 4-8, the SPC believes there is a 15% probability of seeing severe thunderstorms within 25 miles of a point. I-65 and west are within this yellow area.

It’s still five days away, so we will watch to see how this develops. Until then, just be aware that Monday could start of with some rain and maybe some severe weather. We’ll keep watching it.
