Tornado Watch by 5pm ???

From Mesoscale Discussion #0492

"considerable sunshine and boundary layer moistening have enhanced
instability across much of srn ga/nrn fl. 17z sounding from tlh
clearly depicts cap that has suppressed warm sector
development...though isolated showers are now deepening across swrn
ga suggesting steepen low level lapse rates have eroded inhibition
greatly. increasing warm advection across ga will enhance supercell
threat...especially along warm front. additionally...multiple
long-lived potentially tornadic storms will approach wcntrl ga over
the next few hours. tornado watch will likely be required by 21z."

21z = 2100 Zulu = 5pm ET
