The nerd-word of the day is "Diurnal" Temperature Change. That's the change in temperature from day to night. As we transition from Summer into Autumn, we typically see a greater range between the overnight low and the afternoon high for a brief period. Tonight and tomorrow is a good example.
The above graph was created on our new computers at KAIT. It shows the latest run of StormCAST, which is our in-house run computer model. That data you typically see at 10:00 is newer than the data you see at 6:00. We constantly run new loads of data and I have been very pleased with the results!
Anywho, notice that it shows the overnight lows dipping into the low 60s tonight, but bouncing back into the low 90s for tomorrow afternoon. That's a 30 degree swing. So tomorrow morning, it will feel great in the morning... but a little toasty in the afternoon.
By the way, the lower dewpoints that we see during this time of the year allow for the temperatures to drop farther! :)
Stay cool. A few showers arrive on Thursday.
