Unexpected snow hits Marshalltown

The National Weather Service has issued a winter storm warning that will remain in effect until noon Wednesday.

As of 11:40 a.m., 4.5 inches of snow had already blanketed State Center, the closest city to Marshalltown that has sent in updates to the National Weather Service in Des Moines.

Kevin Skow, a meteorologist with the National Weather Service, said the storm traveled farther northwest than meteorologists had expected. The NWS had forecasted snow for southeast Iowa, but the low pressure front threw them for a loop when it traveled northward.

Skow said the storm will continue through Tuesday evening in spurts. Although the snow has tapered in Marshalltown over the noon hour, another bout of it is set to sweep in, adding another 2 to 3 inches in the next few hours.

In total, Marshalltown can expect another 5 to 6 inches of snow throughout the night. Winds are between 20 and 25 mph with gusts close to 30 mph, which will continue through most of the day, Skow said. Overnight, winds will taper slightly, ranging from 10 to 20 mph with gusts reaching 25 mph.

The Marshalltown Police Department put the city’s snow ordinance in effect as of noon, prohibiting parking on snow routes. Police scanner traffic indicates slick road conditions caused several minor accidents in Marshalltown and in rural areas. Police were unavailable with details as of 1 p.m.

All area schools let out early Tuesday.

The low for Tuesday is 28 degrees. Read tomorrow’s T-R for more details.
