Two confirmed tornadoes have happened in SLO
The past few weeks have seen a marked increase in the number of tornadoes east of the Rocky Mountains. Around 245 tornadoes were reported last week, with North Carolina probably being the hardest hit.
April and May historically have the greatest occurrence of these violent storms. Tornadoes nearly always develop from thunderstorms, especially from a class of thunderstorms known as supercells.
This type of thunderstorm can be seen over the Central Plains when warm and moist air moving northward in the lower to mid-levels of the atmosphere from the Gulf of Mexico runs into cold air moving southward from Canada.
