Good Saturday, everyone. We have a nice blast of heat and humidity moving into the bluegrass state this weekend. Temps and heat index values kick if up a few notches, but a cold front is on the way. That front will usher in a significantly cooler pattern. The arrival of this is a week later than I originally thought a few weeks ago.

Highs today will be in the low and mid 90s west with around 90 in the east. Most areas hit the low and middle 90s for Sunday with heat index values reaching 100 or better. Both days will feature a scattered storm, with Sunday having the best chance.

Showers and thunderstorms increase Sunday night and Monday as a cold front sweeps in…

GFS 2

Some strong storms will be possible during this time.

Another disturbance follows that up from the northwest by the middle of the week, and can produce scattered shower and thunderstorms…

GFS 3

These systems look to have much more of a push than the front of the past week. Anytime a front hangs up right on top of you, nasty weather usually develops and we saw that with the severe storms and flooding rains.

Here’s the push of cooler temps showing up for Wednesday and Thursday…

Not only are the operation models on board with a cooler pattern, but the Ensembles are as well. The GFS Ensembles 5 Day average temperature departure into 4th of July weekend…

GFS 4

The same 5 days on the GEPS…

GFS 5

Is that a trend that holds into July? The CFS seasonal model thinks so…

Enjoy your Saturday and take care.
