Morning temperatures will range between 1° and 6°, with around 3° expected in Sofia. During the day, maximum values will generally reach between 13° and 18°, with some locations experiencing slightly higher readings due to the influence of southern winds.

Winds will be moderate to strong, and at higher elevations and along northern slopes may become stormy, coming from the south-southwest.
