- Dense fog may develop in portions of eastern North Dakota and northern Red River Valley tonight into early Thursday.

..Fog potential tonight into early Thursday

Confidence is medium in the occurrence of fog somewhere within eastern ND, although confidence greatly diminishes where this occur with more precision. Driving the fog production is a weak cold front moving into ND from Canada, bringing with it ground- scraping low clouds behind the front. Confidence remains low in more precise locations, with uncertainty mainly stemming from questions on influence of mid level cloud cover.

There remains a low chance for embedded lightning this afternoon into early evening in southeast ND into west-central MN, although confidence was not high enough to include into TAFs.
