On Thursday and Friday, a low-pressure system from the central Mediterranean will bring rain across nearly the entire country. Specific forecasts indicate that on Sunday, Macedonia will experience clouds with local showers and possibly isolated thunderstorms, especially in the afternoon. In the rest of the country, sunny intervals are expected with passing clouds and localized showers in the afternoon in mainly mountainous inland areas, possibly on Ionian islands and northern Aegean by evening. Winds will vary between 3-4 Beaufort, with northerly winds reaching 5-6 Beaufort in the Aegean. Temperatures will range from 20-23°C in the north to 24-26°C elsewhere. In Attica, sunny intervals are predicted with passing clouds mainly in the afternoon, northerly winds up to 5 Beaufort with some weakening, and temperatures from 14 to 26°C.
