Winter Storm: Travel Impacts & ALERT DAY for Southern Minnesota/Northern Iowa

Winter Storm Alert: Travel Chaos Looms for Iowa and Minnesota

A significant winter storm is barreling towards Iowa and Minnesota this weekend, promising a messy mix of snow, ice, and strong winds. Residents are bracing for potentially hazardous travel conditions and significant disruptions.

Storm Development and Track

The storm will develop on the eastern side of the Rocky Mountains, strengthening as it moves into the Central Plains. It’s forecast to track northeastward, impacting western and central Iowa. This positioning will place much of the region on the cold, wintry side of the system.

Moisture flowing northward from the Gulf of Mexico will fuel the precipitation, beginning with a chance of snow on Saturday. However, the situation becomes more complex Saturday night and Sunday, with a higher likelihood of a wintry mix – freezing rain, sleet, and snow – continuing through Sunday night before tapering off.

Uncertainty in Forecast: A Wintry Mix Complicates Matters

Recent data suggests a slight northward shift in the storm’s track. This shift introduces uncertainty, potentially pushing heavier snow accumulations north of Highway 14 into east-central Minnesota. Simultaneously, the chance of a wintry mix near and south of Highway 14 could reduce overall snow totals.

However, if the transition from a wintry mix to snow occurs earlier than anticipated – by midday Sunday – snow amounts could significantly increase. The forecast remains fluid, requiring close monitoring.

High Winds to Amplify Impacts

Adding to the challenge, winds will increase throughout Sunday, with gusts potentially reaching 40 to 45 mph or higher. These strong winds, combined with precipitation, will create dangerous conditions, especially in open and rural areas, potentially leading to near-blizzard conditions.

Alert Day Declared: Prepare for Significant Travel Disruptions

Given the potential for hazardous conditions, an Alert Day has been declared. Snow accumulations of 2-6 inches are likely for areas near the Minnesota-Iowa state line and along the Highway 14 corridor. Further north, accumulations could reach 6-12 inches, with isolated areas potentially exceeding one foot in east-central Minnesota.

These amounts are subject to change depending on the development and timing of the wintry mix.

Temperature Plunge Following the Storm

Following the storm’s departure, temperatures are expected to plummet. Highs will be in the upper 30s on Saturday, near 30° on Sunday, and then drop significantly early next week, with highs likely in the teens on Monday and around 20° on St. Patrick’s Day (Tuesday).
