Areas affected...Southeast Wisconsin

Concerning...Tornado Watch 109...

Valid 142307Z - 150000Z

The severe weather threat for Tornado Watch 109 continues.

SUMMARY...The risk for tornadoes (possibly strong) and destructive
hail will continue with two supercells moving towards the Milwaukee
metro region.

DISCUSSION...Two supercells are tracking eastward toward Milwaukee
and nearby suburbs. These supercells have a history of producing
large to very-large hail in Madison. The KMKX VAD shows ample
low-level shear and near 50 kts of 0-6 km shear. With steep
mid-level lapse rates, large to very-large hail will remain
possible. The tornado threat is greatest with the lead supercell
with KMKX showing periodic increases in low-level
inflow/organization. Tornadoes, potentially strong, are also
possible.
