Areas affected...Coulee Region into central Wisconsin

Concerning...Severe potential...Watch unlikely=20

Valid 242207Z - 250000Z

Probability of Watch Issuance...5 percent

SUMMARY...Isolated marginally severe hail (1-1.5 in.) and perhaps
strong/damaging wind gusts will be possible with weak supercell
structures before storms cross the warm front. A watch is not
expected.

DISCUSSION...Low-level warm advection continues across parts of the
Upper Midwest. While most storms have generally remained north of
the warm front, a few storms have developed where greater surface
heating has occurred within the Coulee region. A storm or two has
shown some weak supercell characteristics east of La Crosse, given
the belt of stronger mid-level flow across the area. Storms will be
capable of marginally severe hail (1-1.5 in.) and perhaps a damaging
wind gust prior to crossing the warm front into more stable air. The
overall threat should remain marginal as mid-level lapse rates are
not as steep as earlier today.
