Mammatus Cloud in Durham on 6th February 2022


The following was observed just after the passage of a very potent shower on 6th February 2022. The ‘cows udder’ appearance of Mammatus Cloud is due to intense updraughts in the base of the cloud, effectively throwing precipitation back upwards. They can be intensely turbulent, and aircraft are best advised to avoid them.

The cold front that passed through actually resulted in a sleet shower and snow was observed on the high ground in the County further south and west.
