| SPC mesoanalysis of Most-Unstable CAPE at 1 AM. Values analyzed in excess of 4,000 J/kg indicate significant energy for severe thunderstorm development and maintenance over northern Illinois. | SPC mesoanalysis of Effective Deep Layer Shear at 1 AM. Values were strong, generally around 35-40 kts, across northeast Illinois supporting organized, sustained thunderstorm development. | SPC Mesoanalysis of Effective Storm-Relative Helicity at 1 AM. Values were maximized mainly north of the Illinois state line, indicate a more favorable region for QLCS tornado development. |
