Description: The photo was taken in the suburb of Zaprešić. The weather was mainly sunny with partly cloudy periods and an air temperature of already 20°C in the morning hours. The air pressure was mainly constant during the day while temperatures had risen to 27°C. Over the country there was a non-gradient pressure field with locally unstable atmosphere. In the early evening a thick, dark Stratocumulus opacus cloud appeared in the west and covered the upper part of the sun. The sun was piercing under the cloud. Stratocumulus and Cumulus clouds are situated in the front part of the photo. Cumulus vertical developments appear in the background. The Cumulus had grown during midnight to a Cumulonimbus that was followed by thunder and showers.
