Areas affected...Western/central Wisconsin

Concerning...Severe Thunderstorm Watch 299...

Valid 101118Z - 101245Z

The severe weather threat for Severe Thunderstorm Watch 299
continues.

SUMMARY...An isolated large hail and damaging wind threat will
accompany a small cluster of storms moving into central Wisconsin
this morning.

DISCUSSION...Warm advection over the outflow from earlier morning
convection has promoted a few stronger/deeper thunderstorms within
the northern Coulee region. This activity is on the fringe of the
steeper mid-level lapse rates and effective shear (perhaps around
25-30 kt). It is not clear how far east this complex of storms will
progress as buoyancy and shear decrease with eastward extent and the
low-level jet will weaken. The current thinking is that isolated
large hail and perhaps strong/damaging winds are possible over the
next 1-2 hours. An additional watch is not currently expected this
morning.
