Mesoscale Discussion 0883 NWS Storm Prediction Center Norman OK 0756 PM CDT Tue May 21 2024 Areas affected...Central and southern Wisconsin Concerning...Tornado Watch 281...282... Valid 220056Z - 220200Z The severe weather threat for Tornado Watch 281, 282 continues. SUMMARY...A developing squall line will quickly progress northeastward through the late evening hours. Damaging wind gusts up to 75 to 85 mph and embedded tornadoes will accompany it. DISCUSSION...Continued upscale growth has led to a north-south squall line developing across central WI. A few embedded mesovortices have been noted, along with a pair of embedded supercells on the southern flank near and north of Madison. The upstream low-level shear environment remains favorable for QLCS tornadoes where bowing segments can surge northward becoming more west to east oriented. In addition, deepening cold pools will continue to support severe damaging wind gusts. Marginally severe hail can't be ruled out, although waning instability and increasing MLCINH will likely keep the threat isolated. ..Barnes.. 05/22/2024 ...Please see www.spc.noaa.gov for graphic product...
