Areas affected...Central and southern Wisconsin
Concerning...Tornado Watch 281...282...
Valid 220056Z - 220200Z
The severe weather threat for Tornado Watch 281, 282 continues.
SUMMARY...A developing squall line will quickly progress
northeastward through the late evening hours. Damaging wind gusts up
to 75 to 85 mph and embedded tornadoes will accompany it.
DISCUSSION...Continued upscale growth has led to a north-south
squall line developing across central WI. A few embedded
mesovortices have been noted, along with a pair of embedded
supercells on the southern flank near and north of Madison. The
upstream low-level shear environment remains favorable for QLCS
tornadoes where bowing segments can surge northward becoming more
west to east oriented. In addition, deepening cold pools will
continue to support severe damaging wind gusts. Marginally severe
hail can`t be ruled out, although waning instability and increasing
MLCINH will likely keep the threat isolated.
