Yesterday we talked about the "pattern shift" in the upper atmosphere that ridded us of that hot dome of high pressure and replaced it with a trough in the Ohio Valley.
This has brought a stationary front at the surface just to the north of Middle TN that will keep the showers and t'storms on the increase for the first half of the week.
That might hold temperatures down in the upper 80s for a few days, but it will still be quite muggy in the off and on rain.
However, by late Wednesday and Thursday, it appears that the front will shove southward and through Middle TN.
Changes are subtle with fronts this time of the year, but it should spell a slight decrease in the humidity, and even keep temperatures in the 80s for a few days in the sunshine on Thursday & Friday.
A stronger front should approach next Saturday with thunderstorms followed by a bigger push of cooler and less humid air behind it. That timing looks like next Sunday, but since that is 7 days out, we know things could change.
Either way, it looks line things will be on the move!
