A high-pressure system has moved into the Ohio River Valley. It’s working to suppress our rain chances. We suppose a shower or two today is remotely possible, but we think that’s really unlikely. We remain hot, with temperatures in the upper 80s, and humid, with dewpoints in the mid to upper 60s.
Showers and storms are possible again today, but they will be hit or miss for us in Williamson and Davidson Counties.
If we get a shower, rainfall could be as high as an inch again today because the PWAT (precipitable water) values are expected around 1.6″ to 1.7″.
Our short streak of 90 degree days continues today: 92º. If we get there, it will tie the May 14 record set in 1881.
Humidity remains high with dew points be in the mid-to-upper 60s. Keep an eye on the little ones — their bodies don’t regulate heat well, and they’re not yet acclimated to this summertime airmass.
The models think today will be sun-filled, less humid, with a high temperature at 81º and falling dew points in the 50º range.
However, our atmosphere remains the same as it was yesterday. We remain on the back side of the system that brought us gusty winds, heavy rain, lightning, and small hail yesterday and last night. This afternoon and tonight, most storm ingredients will be there. Plenty of instability. Dry air aloft and “cold pools” sitting atop us, both help storm development.
