A total of 3.0 inches of wet snow fell from about 11:00 p.m. Thursday until about 6:00 a.m. Friday. Snow cover at noon Friday in Arlington Heights was 3.0 inches on grassy areas and unplowed pavement areas. The snow was wet and good packing. The snowfall ties the one-day snowfall for the season, but is short of another total storm snowfall when 3.75 inches fell from about 1:00 p.m. Thursday February 7, 2013 until 1:00 a.m. Friday February 8, 2013.
Photo of snowfall accumulation with the angle of the camera and parallax making the snow depth appear to be less than the actual 3.0 inches.
At noon Friday, radar showed a very light band of precipitation passing from southwest to northeast over Cook County, DuPage County, and Lake County (Illinois). Very light snow flurries were associated with the radar image. A Winter Weather Advisory remains in effect until 6:00 p.m. Friday.
