A storm is moving into eastern Iowa and will lead to accumulating ice, rain and even thunder across the area.
ROUND 1: Monday morning
Temperatures will stay in the 30s in the north and climb into the 40s in the south. Rain will start to spread across much of the area through the morning. In the far north (Chickasaw, Allamakee, Winneshiek counties) there will be freezing rain. A glaze will be possible today which could create some slick streets.
Showers and isolated thunderstorms will continue down to the south - leading to accumulations of around a half an inch. There will be a break in the precipitation in the evening, after 6 pm.
ROUND 2: Monday night/Tuesday morning
A second round will move in after about 10 pm Monday. As cold air moves further south the threat for freezing rain will be more widespread. Freezing rain will be possible from Tama northeast to Elkader with the higher chances near and north of Highway 20. In this area there will be the potential for a tenth to a quarter of an inch of ice accumulation. This will lead to icy roads and even the potential for some sporadic power outages with ice building up on power lines. There is still some uncertainty on exactly where the heaviest ice accumulation will be but slick roads will be likely through Tuesday morning's commute.
Further to the south rain showers will continue with the potential for some heavy rain at times and isolated thunder.
Precipitation will start to wind down midday Tuesday, but slick roads will continue to be an issue with cold air in place.
Wednesday will be cloudy, dry and cool with temperatures in the 20s. Thursday temperatures will be in the upper 20s to low 30s. A weak disturbance will move in and lead to a wintry mix.
Temperatures will be in the mid 30s Friday through the weekend. There is a slight chance for some light snow/wintry mix on Saturday.
