7/25 - 12pm - More Heat and Scattered Storms

After a couple days of 96 degree weather in Louisville, we're on-track for a cool-down today. How much of a cool-down? Try four degrees. Yep, it's going to be another hot one today. With dew points in the lower 70's today, the heat and humidity will combine to produce heat index values at or above 100. No Heat Advisory will be issued, but it'll still be hot enough to cause problems if you're not hydrated. The other feature of our weather today will be the chance for some showers and thunderstorms around the region. A cool front that's situated just north of the Ohio River will provide a trigger for these scattered storms today, which should begin to form this afternoon. We're just outside of a Slight Risk area for severe weather from the SPC, but I think a few storms around the region could get strong due to increased atmospheric instability and a light touch of shear. A small daily chance for storms will exist through the rest of the week with temperatures hanging around in the lower 90's.

We may think the heat is bad here in Kentuckiana, but there's nothing like a warm July afternoon in Death Valley, California. Look at the forecast for that area today from the National Weather Service: 
Today: Mostly sunny and hot, with a high near 121. Calm wind becoming south between 4 and 7 mph.
