Areas of dense fog have formed this morning in northwestern MN and far northeastern ND. Exercise caution if traveling, and be prepared for rapidly changing visibilities.
Rain is expected to change over to snow late Tuesday night into early Wednesday morning. Changeover timing is still uncertain; however, there is the potential for very heavy snowfall rates of 1+ inch per hour just after the transition occurs. Low visibility and travel impacts are likely.
