Iowa – Snowflakes thicken across central Iowa as traffic slows and tires hiss on icy pavement, a clear signal that winter has taken control. This is a high-impact weather day, with snow followed by dangerous cold.
A Winter Weather Advisory remains in effect for Des Moines and much of central Iowa through mid-afternoon. According to the National Weather Service in Des Moines, 2 to 4 inches of snow are expected, with pockets of heavier snowfall reducing visibility to near one mile at times. Snow accumulation on roads will make travel slick, especially during the morning and midday hours.
Drivers on I-35, I-80, and Highway 65 should plan for slower speeds and sudden slick spots. According to Iowa DOT guidance, conditions may change quickly in heavier bands. Allow extra stopping distance and avoid unnecessary travel if possible. Snow tapers later today, but hazards do not end when flakes stop falling.
A Cold Weather Advisory follows this evening through Sunday morning. Wind chills are expected to plunge as low as 30 degrees below zero. According to the National Weather Service, frostbite can occur on exposed skin in as little as 30 minutes. Flash freezing is a major concern as melted snow refreezes rapidly once temperatures drop.
Sunday turns sunny but brutally cold. Highs reach only the lower teens, and wind chills remain below zero through much of the day. Outdoor plans should be limited, and pets should remain indoors. Emergency kits, blankets, and charged phones are strongly recommended for anyone traveling.
Relief begins Monday as highs rebound into the mid-30s, with sunshine helping roads improve. By Tuesday, temperatures climb near 40, starting a thaw. Refreezing remains possible at night.
This storm marks a decisive December shift into winter. How slick are roads where you are right now?
