The latest 250mb Velocity plots show a very clear split flow in the jet stream as of late, with the Mid-South caught in the middle of it, which usually leaves the area high and dry, and that is not the best of news considering the hydrological situation in the Commonwealth, especially along the Ohio River.
The chances for rain this week look very slim; however, there is the chance, mainly for western portions of Kentucky and Tennessee and into South Central Kentucky and Middle Tennessee toward mid week as a low tracks from the Nation’s Heartland and into Dixie. Because the low will be tracking to the south, and it isn’t the most potent of systems, this will by no means be a drought buster. However, it is a sign of the pattern beginning to change back to a Ridge/Trough pattern, as illustrated by model guidance. However, much like the last time the Mid South saw this pattern, it will once again be near the base of the trough, with the East Coast getting much of the action. So the only thing that will really change with this pattern change are the temperatures, with highs back down into the 70s and lows down into the 40s.
