MD 1830 CONCERNING SEVERE POTENTIAL...WATCH POSSIBLE FOR EASTERN IOWA...NORTHERN ILLINOIS...SOUTHERN WISCONSIN
Mesoscale Discussion 1830 NWS Storm Prediction Center Norman OK 0509 PM CDT Mon Aug 05 2024 Areas affected...eastern Iowa...northern Illinois...southern Wisconsin Concerning...Severe potential...Watch possible Valid 052209Z - 052315Z Probability of Watch Issuance...60 percent SUMMARY...Severe threat to increase this evening. Damaging winds, large hail, and a tornado are possible. DISCUSSION...Surface analysis shows a front extending across the upper Ohio River Valley into portions of the Midwest. Visible satellite shows cu development along this boundary in eastern Iowa and northern Illinois, with a few cells now on radar south of Chicago and north of Davenport. The environment in this region is characterized by MLCAPE around 2000-2500 J/kg and deep layer shear along and north of the boundary around 40-45 kts. The 19z sounding profile from DVN further supports this, with around 2300 J/kg MLCAPE. Shear profiles are somewhat weak in the low-levels, with around 25-50 m2/s2 0-1km SRH in surface objective analysis. However, low level shear should increase through time to around 100-200 m2/s2 per RAP forecasts. CAM guidance suggests a few supercells could develop, with potential for large hail, damaging wind, and perhaps a tornado. A watch may be needed to cover this threat for portions of this area in the next 1-2 hours. ..Thornton/Smith.. 08/05/2024 ...Please see www.spc.noaa.gov for graphic product...

A few tornadoes possible Scattered large hail likely with isolated very large hail events to 2.5 inches in diameter possible Scattered damaging wind gusts to 70 mph likely SUMMARY...Thunderstorms are forecast to intensify this evening with several supercells expected to evolve from the initial thunderstorm activity over southern Minnesota.
