Speaking of the heat, I know there's quite a bit of concern out there between the lack of rain across portions of Western KY and corn getting ready to head into some critical stages of development. Definitely not a combination we want to see right now.
Looking forward, we're dry today with continued hazy conditions. Rain chances start returning to the area on Thursday and Friday as we enter into something called a "ring of fire" pattern. In this scenario, storm complexes will ride the periphery of the heat dome to our west, passing NW to SE through the area. This pattern usually results in some sort of severe weather, mainly in the way of damaging winds and heavy rain. The problem is...it's hard to pin exactly when and where the storms will move until the day of the event. Models are all over the place. Bottom line, keep an eye on the forecast.
Going into the weekend, a frontal boundary looks to fall into the area and eventually stall, creating extra opportunities for rainfall. There's still question as to how the pattern evolves into next week, but showers/storms on the 4th are definitely in play. Given all the uncertainty in the forecast over the coming week, it's hard to definitively forecast accumulations. Saying that, we have multiple chances for rainfall. Hopefully Western KY hits more than they miss!
