WWUS43 KDMX 041942 WSWDMX URGENT - WINTER WEATHER MESSAGE National Weather Service Des Moines IA 142 PM CST Sat Jan 4 2025 ...ACCUMULATING SNOWFALL OVER SOUTHERN IOWA TONIGHT THROUGH SUNDAY EVENING... .A winter storm will arrive later today and bring accumulating snowfall to southern Iowa from tonight through the day Sunday before ending Sunday evening. The highest snowfall will fall near the Missouri border in southwest and parts of south central Iowa. Very dry air will be moving into Iowa from north to south with winds from the north averaging 10 to 20 mph. This will cause a very sharp gradient in snowfall amounts with lower amounts in the northern part of a given county and higher amounts in the southern part of the same county. Any shift in the predicted storm track will therefore have significant impacts on forecast snowfall amounts, so continue to monitor the forecast for the latest updates. Finally, the winds will cause at least some minor blowing and drifting snow where the new snow falls.
