Heat and Humidity Then A Big Change

Good Friday to one and all. Heat and humidity continue to take hold of the weather into the weekend, but a major cold front is about to make sure that’s short-lived. This front will usher in a taste of September temperatures early next week. The transition between the two may fire up some healthy thunderstorms late Sunday and Monday.

Let me begin with a recap of something I wrote for yesterday’s post…

Friday and Saturday feature the hottest days of the summer. Daytime highs range from 90-95 in many areas with a heat index above 100 for many. I know there’s an Excessive Heat Warning (heat index of 110 or higher for 2 straight hours or more or 4 straight days of 105 or higher for 2 consecutive hours on each day ) out for many, but we seem to be lowering the standards for that. This is Heat Advisory material for many in central and eastern Kentucky and some may struggle to even get to that (105 for 2 straight hours or more).

The Excessive Heat Warning began Thursday and this was the end result on the Kentucky Mesonet sites…

Only 7 out of nearly 75 sites managed to hit 90 degrees for a high. This wasn’t even the hottest day of the past week, let alone something worthy of an Excessive Heat Warning.

Here’s a look at the Heat Index temps shortly before 4pm…

Those numbers weren’t even into the Heat Advisory criteria.

I digress.

Scattered showers and thunderstorms will try to go back up this afternoon and evening, especially in the south and southeast. Here are your Friday tracking tools…

The threat for a few storms will increase a bit on Saturday and that could play a factor in keeping temps down just a bit…

Showers and storms will become more widespread on Sunday and that is obviously going to keep temps down. Some of those storms may be on the strong side as a cold front drops in from the northwest. That front moves in here on Monday with more showers and storms around…

That’s also a setup that can put down some very heavy rains in our part of the world… Again.

The air coming in behind that is awesome and is straight out of September…

Highs are going to struggle to get out of the 70s for Tuesday and Wednesday as lows drop into the 50s. It was delayed by Barry, but it will not be denied. 🙂

Have a great Friday and take care.
