Ahead of today's winter weather event, local cities have enacted their snow ordinances.
— The City of Oskaloosa's snow ordinance goes into effect at 6 p.m. today. Parking is prohibited on city streets during the snow ordinance, and vehicles must be moved off the streets until the snow is stopped and plows have cleared the full width of the street. Parking on streets is unlawful until the ordinance is lifted. Sidewalks are to be cleared of snow within 24 hours of the snow stopping.
— The City of Knoxville's snow ordinance is in effect. Residents should not park on the streets until the winter storm has ended and street has been plowed.
— The City of Pella's snow ordinance will go into effect at noon today and remain in effect until further notice. Vehicles remaining on the street or in public parking lots are subject to ticketing and/or towing.
Mahaska and Marion counties are under a winter weather warning today through Wednesday morning. Forecasters predict a heavy, wet snow will fall across Iowa, to be followed by freezing rain in the overnight hours. Afternoon, evening, nighttime and morning travel may be impacted.
There's a quick drop off in accumulations expected. The system shifted slightly east overnight, but most of Marion and Mahaska counties are in an area that's expected to receive between 4-7 inches of snow. Freezing rain could result in up to one-tenth of an inch of ice accumulation.
The Des Moines metro is expected to receive the same, and Cedar Rapids could receive between 6-10 inches of snow.
All of Iowa's 99 counties are under some type of winter storm warning, watch or advisory.
Snowfall will begin after noon on Tuesday and continue through the evening before switching to a wintry mix with freezing rain into the early morning hours on Wednesday.
The exact track of the storm system is still somewhat uncertain, forecasters said, meaning expected totals could still change.
