Areas affected...portions of central Wisconsin
Concerning...Severe potential...Watch unlikely=20
Valid 272307Z - 280030Z
Probability of Watch Issuance...20 percent
SUMMARY...The severe risk associated with an ongoing multicell
cluster across central Wisconsin should gradually decrease over the
next 1-2 hours. Isolated large hail and damaging wind gusts remain
possible in the meantime, however.
DISCUSSION...A multicell cluster with a embedded supercell
structures continues to track southward along and west of the I-39
corridor in central Wisconsin having produced several reports of
hail up to 2" in diameter and damaging wind gusts in the Wausau,
Wisconsin, vicinity over the past 1-2 hours. Expectation is for this
cluster to persist for another hour or two as it propagates
southward along an east-west oriented cold front and to the west of
a weak, north-south oriented lake breeze. Latest objective analysis
indicates that available buoyancy generally decreases with southward
extent. Coupled with the gradual onset of nocturnal low-level
cooling/stabilization, this should yield a gradual weakening of this
cluster with time. Modestly steep mid-level lapse rates and around
30 kts of effective shear amid moderately strong northwesterly flow
aloft (as sampled by the GRB VWP) will continue to promote a risk
for large hail with the strongest updrafts in the meantime, however.
Steep low-level lapse rates west of the lake breeze boundary will
also support a continued threat for isolated damaging wind gusts.
