Clouds will break up along the Black Sea coast on Sunday, but will be thicker over the south coast in the afternoon. A moderate east wind will keep highs between 11C and 13C, the National Institute of Meteorology and Hydrology (NIMH) said.
Cold air, which the institute had already reported on Saturday, 14 November, will spread across the whole country overnight.
On Saturday, 14 November, the national weather institute forecast Sunday highs of between 7 and 12 degrees across the country and around 8 degrees in Sofia.
Waves at sea will reach 2-3 on the sea-state scale. The water is 13-14C off the north coast and 15-16C off the south. Air pressure will fall during the day but stay above the average for the month.
Saturday night will be cloudy in most regions. Rain, including in south-east Bulgaria, will weaken and stop, and the wind will die down in most places. Lows will be between 0C and 5C, and about 1C in Sofia. After midnight, fog will form in places and cut visibility, mostly on the Danube plain and in enclosed valleys.
By noon on Sunday, visibility in foggy areas will improve, and cloud will briefly break up and thin out. The sky will then cloud over again from the west, with a moderate east-south-east wind. Daytime highs across the country will be between 7C and 12C, and about 8C in Sofia.
It will be cloudy in the mountains. At lower levels the wind will be moderate from the south-south-west, while higher up it will briefly turn strong from the west. Temperatures will be about 7C at 1,200 metres and about 3C at 2,000 metres.
Sunday night will bring a few showers in places in western Bulgaria. Monday will be mostly cloudy, with fog on the plains and almost no wind, or a light south-south-west wind. Towards Tuesday, rain will move from west to east and reach many places, and the west-north-west wind will strengthen. On Tuesday morning the rain will stop quickly, cloud will break up and briefly thin out, and the wind will ease. In the western half of the country, a south-west wind will pick up again and temperatures will start to rise.
