January 30-February 1, 2021 winter storm

NOTE: The pressure and wind observations, as well as the rating, is based on what occurred in northeastern Madison County, Indiana, and not nationwide. In late January and into early February of 2021, one of the most significant winter storms to impact Indiana in several years moved across the region, providing anywhere from 2 to 4 inches further south to over 10 inches further north on just the night of January 30 alone. The sixth major winter eventof the Winter of 2020-21, this event was well forecast, with the National Weather Service issuing winter storm warnings about 20 hours before the onset of heavy snow across the region.

Near-whiteout conditions were reported at times on the night of January 30, and winds gusting to around 30 mph allowed for blowing snow to develop. After about 8 inches of snow overnight on January 30, an additional ~2 inches on January 31 allowed snowfall totals to round out to around 10 inches. This made this system a Category 4 snowfall event. The snow accumulated from this snowfall event melted only about a quarter of a inch by the time of the onset of the even more significant Valentines Day-Presidents Day winter storm, which produced an additional foot of snow on top of the 10 inches of snow that had already accumulated.
