This unusual weather phenomenon will dump TORRENTIAL rain on Sheffield TODAYÂ
Sheffied is set to get a soaking later today due to a not often seen weather phenomenon.Â
Later today a '˜squall line' is set to pass over the city bringing an intense burst of torrential rain and strong winds.
A squall line is a thin band of intense rainfall and high winds which sometimes forms ahead of a cold front. The phenomenon can sometimes lead to frequent lightning, tornadoes and waterspouts. It is also known as a quasi-linear convective system. The line of bad weather is running down the length of the country and is moving from west to east.
A squall line hasn't passed over Sheffield for nearly a year.
On January 24 this year a squall line passed over Sheffield during the morning rush hour bringing a short spell of torrential rainfall.Â Â
