On 23 December, GOES-16 Day Snow-Fog RGB images (below) displayed a long but narrow plume of HCRs that originated over the southern end of Lake Manitoba — which crossed the US/Canada border and streamed across far northeastern North Dakota and northwestern Minnesota. Surface visibility was reduced to 1/4 mile at some sites in Minnesota where the HCR signature was observed; wind gusts as high as 52 mph were reported across that area.
