A slider system will bring a rain/snow mix to northern Iowa later tonight with some thunder dynamics followed by strong winds on Thursday so read on for details…
A low pressure system will dive southeast out of Canada later today bringing a risk for rain and snow to the northern half of the state tonight. We should start to see rain showers with possibly some thunder around 6-7 pm this evening across northwest Iowa. This threat will gradually press east overnight into Wednesday morning as rain changes to snow. Below is the forecast radar valid tonight through Wednesday AM.
Snowfall accumulations of a trace-2″ expected with main accumulation on grass and elevated surfaces. Temperatures throughout this event will be in the low to mid 30s making it tough for snow to accumulate in the southern areas of the light blue shaded zone. Snow forecast valid tonight through Wednesday morning.
A second storm system will move across the northern plains Wednesday night into Thursday with Iowa being on the southern edge. I wouldn’t rule out some flurries for the north central to northeastern counties by Thursday morning but that will be it precipitation wise. After the front passes…northwest winds will become fairly strong Thursday afternoon. I do believe a wind advisory will be needed during this time. The enhanced zone is for wind gusts of 30+ MPH and the moderate risk is for wind gusts of 40+ MPH.
