First off, welcome our special guest on the video for the summer!
Speaking of summer, that "feeling" is back full-on the next several days.
The humidity and heat is building west of I-65 first...slowly spreading east over the next 24 hours. At the same time, there will be a boundary near I-70 later today/tonight that could spark a thunderstorm.
The environment is not great for them to survive very long within the boundaries of WAVE Country. Having said that, our northern edge (Lawrence, Jackson, Jennings) are just unstable enough that any thunderstorm that does develop could move into your area. So heads up on that potential.
And that piece of the forecast is important when it comes to Friday's setup. Whatever develops later will likely push a weak boundary south into southern Indiana Friday. Once the sun heat that up, new develop could pop. Otherwise, another hot day ahead.
Saturday will depend on Friday's boundaries (see a pattern here?). But it does appear something will be draped across WAVE Country so I think this is the day that will get a bit more active with thunderstorms morning and night. We will likely see thunderstorms near dawn that will fade at lunch, then re-develop in the afternoon. Exact locations for both rounds is just too difficult to say just yet. But everyone is at risk. And some of the afternoon stuff could get rather strong with wind and hail. We will need to watch that.
Signs are still there that this "southward trend" of the boundaries should keep going into southern KY Sunday or even Monday. If so, this may give northern sections a break. Stay tuned for more info on that.
The "boundary zone" will then lift back north next week with more thunderstorms and heat.
Here is today's video update to explain all of this plus an update to the TROPICS.
