Areas affected...Southern Indiana into southwest Ohio
Concerning...Tornado Watch 70...
Valid 302235Z - 310030Z
The severe weather threat for Tornado Watch 70 continues.
SUMMARY...The severe risk will continue spreading eastward across
southern Indiana (in Tornado Watch 70) and eventually into Southwest
Ohio . A downstream watch will be issued by 23Z.
DISCUSSION...A northeast/southwest-oriented QLCS is tracking
eastward across central and southern Indiana at around 40 kt. Along
the southern portion of the line, an organized line segment is more
favorably oriented to around 50 kt of southwesterly deep-layer
shear, and this activity has produced severe wind gusts up to 70
mph. Given the organized linear mode, severe gusts upwards of 70-80
mph will be the primary concern. However, some deeper/rotating
updrafts embedded in the line, along with isolated/discrete cell
development immediately ahead of the line, will be capable of
producing hail up to 1.75 inches and a couple tornadoes.
With time, these storms will continue eastward into southwest OH,
where a continued linear mode should favor primarily severe wind
gusts. While severe wind is the primary concern, a couple embedded
tornadoes will also be be possible, especially given a stronger
low-level jet and larger clockwise curved hodographs (around 200
m2/s2 effective SRH) into southwest OH. A downstream watch will be
issued by 23Z.
