Patchy fog will slow you down this morning, especially in northern and southern Iowa. Some spotty light rain showers will move across the northern border of the state off and on today. Today will begin warm but a cold front will arrive late in the day. This will lead to falling temperatures Tuesday night through Wednesday. Wednesday will be cold and blustery with mainly cloudy skies and a few flurries. Highs by Friday and Saturday will not be able to rise out of the teens. There is another chance of snow on Sunday.
