Some thundershowers Wednesday dropped just a touch of rain on Moose Jaw but it was enough for the region to produce a thick fog to start the new day.

Officials have issued a fog advisory for Moose Jaw and Regina, down to Assiniboia over to Swift Current and then up to the Battlefords. The warning says there are some patches of zero visibility and caution is advised.

As things start to warm up, the fog should move out allowing for some sunshine this afternoon.
