OSKALOOSA — Mahaska and Marion Counties are included in a winter storm warning issued by the National Weather Service ahead of a Tuesday snow event.
Forecasters say a wet, heavy snow is coming for central Iowa and could lead to power outages due to the weight of the snow on trees and power lines. Some freezing rain could fall late Tuesday, making road conditions even more slick.
About 5-8 inches of snow are expected in Knoxville, Pella and Oskaloosa, as well as the Des Moines metro. Northern Mahaska County, and most of Jasper and Poweshiek Counties, may receive up to nine inches of snow.
Precipitation can begin as soon as Tuesday morning, but snow is expected at a higher rate beginning in the afternoon hours on Tuesday. Precipitation will continue through the early morning hours of Wednesday, with a wintry mix beginning late Tuesday night.
Forecasters remain uncertain about exact totals as they pinpoint the exact track of the system. The system that will bring the snow was in California as of the last update Monday morning, still yet to make its way over the Rocky Mountains to the midwest, and Iowa.
Heavy snowfall is forecast to begin after noon on Tuesday across the Herald's coverage area.
The winter storm warning will go into effect at 9 a.m. Tuesday and continue until Wednesday at 6 a.m.
Every county in Iowa, except for Lee County, is included in some type of winter weather advisory or warning ahead of Tuesday's snow event.
Road reports will be available through 511ia.org. The National Weather Service recommends traveling with a winter weather emergency kit, which would include an extra flashlight, food, extra blankets, boots, mittens and warm clothes.
