The problem here is that we are talking about small features until the main trough/front comes through on Monday. Models do not handle them well. One subtle difference here or there makes a big change in the weather on the ground.
What forecasters need to do is look at the set up and use the general model date, but throw out the specific details for a specific location forecast. With a strong trough digging to our west, our flow will back around and turn from the NW to the W and SW. This will result in an energy in the atmosphere to travel more W to E. It seems unlikely that it will go SE of our area.
This should result in a chance for some showers/thunderstorm in the morning on Sun, but more likely late afternoon/evening and into the overnight. There could a couple rounds of storms. Some could bring hail, strong winds and of course heavy rain and lightning.
Conclusion: Saturday should be good. Maybe a stray shower ... but very unlikely. Sunday will be cloudy to start with some rain possible, then at least some partial clearing, becoming hot, humid with some more storms erupting in the afternoon to our west and then moving east late. Highs at least to 86, with enough sun to 90.
Keep an eye to the sky on Sunday. Then prepare for some really refreshing air for most of next week.
