Tornado-like events have been spotted near Lincoln after 4pm on June 4.
Readers sent to The Lincolnite photos of what look like tornadoes, visible from North Hykeham, Welton, Scampton, Belton, Witham St Hughs, Carlton Le Moorland and even as far as Pinxton near Mansfield and Alkborough in North Lincolnshire.
Tornadoes form when the weather is unstable and showery, according to the Met Office.
They are narrow, spinning columns of air that reach the ground from cumulonimbus (thunderstorm) clouds.
As they develop, funnel shaped clouds extend from the base of the cloud, and it is only when these funnel clouds touch the ground a tornado is formed.
