4/10 - 4/11 Winter Storm (Update #2)

Once again with a strengthening trend to the system and increasing cold air returning from the northwest, the snowfall forecast has increased and thus changes have been made to advisories/watches and now warnings! Areas of Iowa along the Minnesota border have the potential for nearly a foot of snow by the end of Wednesday. Other areas in the northern third of the state will see over a half foot of snowfall during the same time period. Even along a rough line of Sioux City to Ames to Davenport and northward are expected to see over 3 inches of snow and are in some sort of winter storm advisory. Areas just south of that line may still see snowfall, however under 3 inches is expected and thus no advisories have been issued for them. Travel conditions even with small amounts of snowfall will be treacherous, as slick conditions will prevail.

Currently, rain showers over the southern half of the state are underway. While snowfall has continued over the northwest corner of the state, mainly moderate although in Sioux Falls heavy snow was reported at 4 PM. Expect precipitation to increase overnight, with areas in the northern third of the state to see this change over to snow overnight. The rest of the state will see a changeover to snow during the morning hours tomorrow, with continuing snowfall throughout the day.
