The Balkans region experienced significant temperature variations last week, characterized by large diurnal ranges—substantial differences between daytime highs and nighttime lows. Clear skies and high pressure brought warm days, while the absence of cloud cover led to rapid cooling overnight in Montenegro. This phenomenon occurred as a low-pressure system started its movement towards the Aegean Sea. Forecasters predict this system will bring heavy rainfall to Greece. The temperature swings were due to heat escaping into the atmosphere unimpeded by clouds during the night. Further updates on this developing weather situation are anticipated as the low-pressure system progresses.
