The snow swaths — which appeared as brighter shades of green in the RGB images — slowly melted during the late morning and early afternoon hours.<\/p>\n

Note that Mandan (located just west of KBIS) was reporting “precipitation of unknown type” with an air temperature of 32\u00baF — indicating that this feature was a lake effect cloud band which was producing light precipitation (predominantly snow).<\/p>\n
