Accumulating snow chances return to Iowa on starting late Tuesday afternoon through Tuesday evening. Snow accumulation of 1 to 2” are expected for most, although some areas over far northern and northeastern Iowa may see amounts closer to 3 inches. Snow may lead to slick travel, use caution if driving.
We see slightly more seasonal temperatures through mid-week, before much colder air returns to end the week with wind chill values dropping into the -20s to -10s. Light snow will be possible over northern Iowa late Tuesday then again on Wednesday. Breezy winds on Wednesday may lead to reduced visibility in snow showers.
