An extremely warm day in the western Balkans yesterday, Apr 18th. The foehn effect of southwest winds from the Dynaric mountain range into the plains to its east has pushed the relative humidity very low, while the temperatures climbed significantly. Most of the countries have reported temperatures much above the 25 °C threshold, many were in the upper 20s. While the weather station in Bitola, North Macedonia reported even a hot day – it was +31 °C in the afternoon!
