MD 2259 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR COULEE REGION INTO CENTRAL WISCONSIN
Mesoscale Discussion 2259
NWS Storm Prediction Center Norman OK
0507 PM CDT Tue Oct 24 2023
Areas affected…Coulee Region into central Wisconsin
Concerning…Severe potential…Watch unlikely
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.
