During the day on Wednesday, thunderstorms will be most intense in Central and Eastern Bulgaria, gradually easing by evening as precipitation moves eastward and clouds begin to clear. A northeast wind will prevail, shifting to a northwest wind in Western and NW Bulgaria later in the day, bringing cooler air.
