Shew...over it yet? Get ready for a long period of 90 degree heat. The only thing really to break the streak would be some afternoon clouds or a thunderstorm to knock is down for an hour or two.
The issue we will need to really what is how high the dewpoints get in the coming days. They look to average 70-75 degrees along and east of I-65 at times this weekend. And 75-79° to the west. The difference? The higher that number is, the higher the heat index can climb in relation to the air temperature. This means heat index values look to average out HIGHER the more west you travel.
Louisville is usually an exception with the urban heat island effect.
Poor air quality will also be an issue with the lack of decent wind aloft. The plus side to that setup is thunderstorm risk stays low.
The heat core still looks to shift east Sunday and Monday. But how much of the ridge will "ease" over us? That is the tougher part. I am leaning the forecast toward "very little" right now. It will still be our best shot at some scattered thunderstorms, but I don't think much relief from the heat will be noted at all.
In fact, I think we will coast through the 4th of July holiday into about July 10th with a stretch of 90s.
After that, signs remains of a breakdown that will allow for more clouds/thunderstorms and therefore slightly lower temps.
