The cold temperatures and heavy rains yesterday made many of us wonder if we might not have yet returned to the dead of winter as we turned on our central heating – in May – through curses and clenched teeth.
If the uninterrupted rain flooding the sidewalks wasn’t bad enough, the city’s weather observers got a little scared of what appeared to be the sight of some sort of “tornado” a few miles north of the city. in the Campsie Fells region.

They showed a strange yellow circle forming north of Glasgow in the area between Fintry and Lennoxtown, with a strong purple band circling it in a circular fashion like an eye – which caused people to joke that it looked like In the Eye of Sauron from The Lord of the Rings.
While speculation surfaced that the Campsie Fells might have witnessed a small tornado or funnel cloud spinning in the sky, the reason for the bizarre “eye” formation appearing on weather maps was due to weather radar located in the area.
Glasgow Live contacted the Met Office for comment on the photos, and we were told they were caused by the radar located at Holehead in the Campsie Fells north of Lennoxtown, with the bright colors on the radar images until a “light bandage “.
A spokesperson said: “In this situation, the brighter colored ring extends in a circle around the location of the radar and results from the intersection of the radar beam with a layer of slush or hail. .
“Radars give an indication of where there is precipitation and the intensity of precipitation is indicated by the strength of the radar returns. they are bigger than raindrops).
