Multiple supercells moved east/northeast across the area during the evening hours of the 28th. One supercell in particular was quite strong producing multiple long track tornadoes. The first tornado began northwest of Perryville, MO and was on the ground for just over 1 hour, traveling 50 miles into Jackson and western Franklin counties in Illinois. After merging with a storm coming out of Williamson County, the supercell storm took some time regaining its strength. It eventually produced another tornado in White County Illinois near Crossville, that moved into Gibson and Posey Counties Indiana before dissipating some 50 minutes later near Oakland City, IN. This tornado path was around 44 miles long. This supercell storm entered our forecast area in western Perry County Missouri about 7:45 PM. It then proceeded east northeast, before exiting our forecast area in Pike County Indiana about 11:15 PM.
The line of storms that raced through the area during the early morning hours produced widespread damaging winds, in particular across western KY. A brief tornado developed along this line affecting the Cuba, KY area shortly after 5 AM. This line of storms entered our far northwest counties, Jefferson and Perry Illinois, about 3:15 AM and exited our forecast area in western Kentucky around 6:45 AM.

Environment (Click images to enlarge them)
SPC Severe Weather Event Feb 28, 2017
An upper level disturbance was moving out of the Rockies during the day, which induced a broad area of low pressure to develop, and a cold front to form which stretched from eastern Iowa into northwest Texas by Tuesday afternoon. This front progressed eastward toward our area during the evening and overnight hours.
6 PM Analysis:

| 500 mb Height, Temperature, & Wind at 6 PM | 850 mb Height, Dewpoint, & Temperature at 6 PM | MSL Pressure and Surface wind at 6 PM |
The environment became very conducive for severe storms to develop as ample moisture (surface dewpoints into the low to mid 60s) streamed north from the Gulf of America, along with moderate instability (MLCAPE values over 1000 J/kg), and strong deep layer and low level shear (effective bulk shear values were over 70 knots). The Significant tornado parameter which assesses the ingredients available for tornadic storms, exceeded a 4 across southern Illinois at 8 PM. This was very concerning, indicating an environment that was very favorable for tornadoes to form within any of the storms.
