A mix of rain and snow is expected across Iowa late tonight through Wednesday. National Weather Service meteorologist Frank Boksa says travel conditions could be poor tomorrow morning as some snow and ice accumulations are possible. Temperatures are expected to rise above freezing later in the day.
“During the day, the warmer air pushes in and our precipitation will change from the mix over to rain for pretty much all of the state by Tuesday afternoon,” Boksa said. “But we do introduce some instability in the atmosphere, so we’re looking at the potential for thunderstorms as well Tuesday afternoon and into the evening hours.”
A couple of the storms could also produce small hail. The precipitation is expected to change back to snow Tuesday night into Wednesday, but only light accumulations are possible – mainly across northern Iowa. “It’s mainly north of Highway 20 where we’re looking for an inch or two at most,” Boksa said.
A Winter Weather Advisory is posted for far northwest Iowa Tuesday through noon on Wednesday. Strong winds are expected on Wednesday. More rain and/or snow is possible across the state Thursday and Friday. High temperatures throughout the week are expected to be in the 30s and 40s.
