We are on track to end the month with an open storm window which means several opportunities for precipitation. A quick round of light flurries/scattered snow showers will work through northern Iowa tonight. Then colder temperatures will arrive Friday ahead of our next chance of snow. A low pressure system will be centered over Colorado on Saturday which will develop snow across Iowa during this time stretching into Sunday. Latest thinking with this round is light to moderate snow accumulations at most. So this will not be anything major. We will have sustained winds around 10-15 MPH during the period so some light blowing of snow is possible but nothing like the recent clipper system we had earlier this week. The higher end snowfall amounts in the MODERATE scale will likely be found across the 1 to 2 northern county rows of the state.
Then all eyes are going to turn to Sunday night into Monday. My in-house model grids are all over the place with this one right now so what I will say is confidence is not very high at the moment but It’s possible that a second system can follow the first one to end the weekend and open the work week. I will carefully continue to monitor this trend and update then.
