The severe weather threat for Tornado Watch 186 continues.
SUMMARY...Supercell with a strong tornado to persist eastward across
southern Mississippi south of US84 and will be approaching the I-55
corridor soon.
DISCUSSION...A supercell has strengthened rapidly and is currently
producing a strong tornado (estimated wind 135-180 mph) near
Meadville, MS. This storm is moving within a volatile environment of
moderate to strong MLCAPE increasing low-level SRH (around 200-250
m2/s2 from DGX to HDC). Effective STP is analyzed to the south
around 2-3. It is likely that this storm will persist downstream to
east with potential for continued strong to intense tornadoes.
MOST PROBABLE PEAK TORNADO INTENSITY...140-170 MPH
MOST PROBABLE PEAK WIND GUST...55-70 MPH
MOST PROBABLE PEAK HAIL SIZE...1.50-2.50 IN
That biggest tornado has already been on the ground for 40 minutes. Not good.
