Front cover: Cumulonimbus calvus and Cumulonimbus capillatus (with the mature anvil of the latter, showing some weakly defined mammatus (supplementary feature mamma ), occupying the top half of the image) clearing rapidly eastwards after the passage of a line of heavy, wintry showers, late in the afternoon of 11 March 2021. The showers produced gusty winds and small hail (~5mm diameter or less) mixed with rain and sleet. Viewed looking north‐northeast from Stoke Hill, near Exeter (Devon). (© Matt Clark) image
