Recap of Severe Weather June 9th, 2018

Tornadoes

The Enhanced Fujita (EF) Scale classifies tornadoes into the following categories:

EF0 Weak 65-85 mph	EF1 Moderate 86-110 mph	EF2 Significant 111-135 mph	EF3 Severe 136-165 mph	EF4 Extreme 166-200 mph	EF5 Catastrophic 200+ mph

Flooding

Abundant moisture was in place with this system, with Precipitable Water values over 1.75 inches. An upper level disturbance was also strengthened across the region from the overnight storms across northern Illinois. The combination of the abundant low level moisture and the slow moving upper level disturbance resulted in high rainfall rates and flash flooding. The heaviest rain on Saturday occurred across south central Lower Michigan where radar estimated that around 5 inches of rain fell across the south central portions of Cass County Michigan. As a result, flash flooding occurred near Edwardsburg, Michigan. The heavy rainfall on Saturday continued an active pattern of the previous 2 days. Pockets of heavy rain over the last few days can be seen on the radar estimated rainfall amounts below.

Environment

Visible Satellite Imagery from around 2pm. Note the curl in the clouds coming out of northeast Illinois. This was an mesoscale convective vortex (MCV) from earlier storms across northern Illinois that aided in renewed thunderstorm development.	850 mb RAP analysis from 5pm. Note the small scale cyclonic circulation across northern Indiana associated with the MCV moving out of northern Illinois.	850 mb RAP analysis from 5pm of 850 mb moisture transport. Notice weak axis of low level moisture transport into northeast Indiana at this time.

RAP analysis from 5pm of precipitable water (PWAT). Note a bullseye of very high PWAT's across far northern Indiana/southern Lower Michigan of 1.8+ inches.	RAP analysis of effective shear from 5pm. Note the pocket of slightly higher effective shear across northeast Indiana (25-30 knots).	RAP analysis of 0-3 km storm relative helicity (SRH). Note the pocket of slightly enhanced 0-3 km SRH values across northeast Indiana.

RAP analysis of Lifting Condensation Level (LCL) heights from 5pm. Note the relative minimum in LCL heights across southern Lower Michigan/extreme NE Indiana. Lower LCL heights provide a favorable environment for tornadoes.
