Summary of Aug 19 rainfall

               Issued 825 pm CDT Sun Aug 19 2012

   Looking at radar estimated rainfall from our new Dual Polarization capability and the legacy calculations, it appears that about 70-80% of the southern WI area received rainfall today.  Some of the heavier amounts, likely exceeding 1 inch, are in the green shades on the images below.  Rainfall above 0.50" appears in the blue shade.  Some spots that received the heavier amounts include eastern Marquette County, northern Green Lake County, eastern Fond du Lac and western Sheboygan Counties, along with eastern Dane County.  Another area with heavy rainfall and quite a bit of hail was in central Ozaukee County, where golfball hail and about 1.5" of rain was observed near Grafton. 

The 1st image is the Dual Polarization estimate from the past 12 hours, while the 2nd image is the legacy Doppler rainfall estimate.
