Mostly clear skies on Thursday allowed the sun to do some much needed snow removal work over northern Iowa. The clear skies also allowed various satellites to monitor the progress! The featured lapse is from the GOES-East satellite from about 8 AM till 7 PM on 19 April 2018. You can easily see the snow line creep north as the snow is melted away. The snow that remained overnight is helping to create record or near record low temperatures over Iowa on Friday.
