Scattered showers and thunderstorms will arrive by about 1 PM. We’ll see these on and off throughout the afternoon until it finally picks up and moves to the east before midnight.
Look Closely at this HRRR model
Notice the motion of the atmosphere? How it’s moving in a counterclockwise fashion?
These storms are in direct contact with, not only a stationary frontal boundary, but also an upper atmospheric low pressure system. Winds always flow counterclockwise around a low pressure system, hence the flow of these showers and storms in the model
Much of Tennessee will be situated under a trough (area of low pressure) this afternoon that will move eastward before midnight.
Our afternoon hit-or-miss storms come from multiple directions due to the turning fashion of the low pressure system above. We’ll get hit from the south first, then tonight the storms will hit us from the north.
And with all this rain we’ve been getting, remember: Turn Around, Don’t Drown.
Rainfall Totals Until Sunday Have Not Changed
We’re ending our last bit of rain this afternoon and in total, WPC shows about 1-1.5 inches accumulated by Sunday.
On the other hand, the Euro shows a little less that 1.5 inches.
