Friday – Central Plains
NUMBER OF TORNADOES EXPECTED: 2-5 – CONFIDENCE: Normal
Tornado Hot-spot: None
Pros: Moderate to high instability, good low-level directional shear and speed shear, decent upper-level support.

Saturday – Central Plains, southwestern Midwest
NUMBER OF TORNADOES EXPECTED: 3-8 – CONFIDENCE: Normal
Tornado Hot-spot: None
Pros: Moderate to high instability, decent/good low-level directional shear, decent/good speed shear, decent upper-level support.
