If you watched last night I showed how an upper low would come out of the west and move across the front as it came down our way. Well, the boundary came down slowly. We got warmer than we expected today and it was very muggy. Our winds had a southerly component while the winds behind the front in Indy were out of the north. That convergence area of the front where the southerly winds bumped into the northerly winds is where we got some lift. There isn’t much steering so the storms just drifted east and then slowly south as the convergence line..the front..drifted south as well.
If you look at the above shot of late evening, you can see the winds out of Bowling Green out of the sourh whereas all of the winds to the north are out of the north…..keep in mind the northerly breeze in Louisville is due to local effects of storms. Anyway, the upper low in this shot is lifting up activity from our southwest and should run into the frontal boundary slipping down from the north. When they meet, that is worth watching. Probably nothing will happen but if it does, it will be there.
This stuff clears out and we get nice weather for the next few days. More humid on Friday and Saturday with a front Saturday afternoon perhaps causing some excitement.
I’ll see if I can’t find something good for this date in history.
