A heavy fog descended upon Estevan Friday morning around 6:30 a.m.
There's no fog advisory in effect, and Environment Canada says that visibility is four kilometres as of 7:06 a.m.
The humidity is 97 per cent, and something of a repeat of Thursday night's thunderstorm that hit Estevan and the surrounding area could be in the cards. Environment Canada is calling for a 60 per cent chance of showers and a risk of thunderstorms during the day and night Friday.
