For late May, it’s harder to get much quieter than this. Aside from Friday and Saturday, tornado threats over the next seven days look pretty minimal.
1-3 Day
Tuesday – Eastern Southeast
NUMBER OF TORNADOES EXPECTED: 3-8 – CONFIDENCE: Normal
Tornado Hot-spot: None
Pros: Moderate instability, good speed shear, decent low-level directional shear.
Cons: Somewhat weak upper-level support and clouds and rain already in the threat area could limit tornadic storm development, storm mode will be mostly linear due to unidirectional mid-to-upper level winds.
Wednesday – Eastern Southeast, southern Virginia
NUMBER OF TORNADOES EXPECTED: 2-6 – CONFIDENCE: Normal
Tornado Hot-spot: Carolinas
Pros: Decent/good low-level directional shear, good speed shear, decent/good upper-level support.
Cons: Unidirectional/backing mid-to-upper level winds, low instability.
Thursday – Central High Plains
NUMBER OF TORNADOES EXPECTED: 1-4 – CONFIDENCE: Normal
Tornado Hot-spot: None
Pros: Low to moderate instability, good low-level directional shear.
Cons: Unidirectional mid-to-upper level winds, fairly weak low-to-mid level speed shear, questionable storm coverage and storm mode.
