Dense fog will once again impact parts of the region tonight into Sunday morning, with the best chance for impacts in the Red River Valley of ND and MN and across northwest MN generally along and north of US Highway 10. Where dense fog occurs with sub freezing temperatures slick spots could develop on roads, sidewalks and other surfaces. Use caution if traveling tonight as conditions could quickly become hazardous.
Warm temperatures will be accompanied by fog tonight, which will persist into Sunday morning. A fast moving system Sunday evening will produce a light wintry mix north of US Highway 2. Meanwhile, temperatures on Sunday will rise into the 50s across southeastern ND. More fog may develop Sunday night.
A winter storm will impact the region late Tuesday into early Thursday. Uncertainty remains in where the system will track. The track will have major implications as for how far north warm air is able to push, which will determine where the rain/snow line sets up. Check back the next several days for updates as the forecast is refined.
