Dubuque, Iowa – Above-normal precipitation combined with near-normal temperatures may increase snow chances across northeastern Iowa from Jan. 3–9.
According to the NOAA Climate Prediction Center’s 8–14 Day Outlook, northeastern Iowa is favored to receive above-normal precipitation during the first full week of January. Temperatures are expected to remain near seasonal averages, a pattern that supports snowfall potential across the region, especially during overnight and early-morning periods.
The outlook reflects a 33–50% probability that precipitation totals exceed early-January averages. While this long-range guidance does not identify individual storm systems, it suggests a weather pattern favorable for multiple snow events rather than a single major winter storm.
Colder nighttime temperatures across northeast Iowa increase the likelihood that precipitation falls as snow rather than rain. Rural areas and higher elevations along the Mississippi River bluffs may see more consistent accumulation, while brief mixed precipitation is possible during marginal temperature periods.
Travel impacts are possible along U.S. Highway 20, U.S. Highway 52, U.S. Highway 61, and Interstate 380, as well as secondary rural roads that can become snow-covered quickly. Commuters, agricultural operators, school transportation, and freight drivers should be prepared for slick roads and reduced visibility during snowfall events.
The Climate Prediction Center emphasizes that 8–14 day outlooks represent probability trends, not guaranteed outcomes. More detailed forecasts, including snowfall amounts, timing, and potential winter weather advisories, will be issued by the National Weather Service as individual systems develop.
Residents are encouraged to monitor updated forecasts, prepare vehicles for winter driving, and remain alert for possible winter weather advisories or warnings as early January approaches.
