Storms may continue to develop in southern Wisconsin and move into northeast Illinois, but the trend may involve a weakening of the thunderstorm cells. Some loud thunder with sporadic cloud-to-ground lightning was observed between 11:30 a.m. and 12:30 p.m. in the northwest suburbs. More severe thunderstorms crossed the area of DeKalb, Sandwich, Lake Holiday, Morris, and Channahon. A Tornado Warning was issued at 11:56 a.m. for Kendall County and La Salle County, Illinois and expired at 12:30 p.m. At 1156 AM CDT, a severe thunderstorm capable of producing a tornado was located near Somonauk, or near Sandwich, moving southeast at 45 mph. Radar indicated rotation, but the storm that prompted the warning weakened below severe limits. A Severe Thunderstorm Warning was issued further east near Joliet and Aurora.
Weather Radar (also nexrad.chgowx.com) shows the trail edge of storms over Arlington Heights at 12:40 p.m., but the leading edge of storms looks severe in Will County, Kendall and Grundy counties. The radar shows a bowing echo which indicates high winds are possible in Will, Kendall and Grundy Counties … and counties south and west of those counties. The SPC Day 3 Categorical Outlook issued May 14, 2019 put our area at enhanced risk of severe thunderstorms. Today’s outlook put us in a 2% Tornado Risk.
