   Areas affected...eastern Minnesota into far northwest Wisconsin

   Concerning...Heavy snow 

   Valid 311549Z - 311845Z

   SUMMARY...Heavy, wet snow may lead to continued snow accumulation
   through early afternoon.

   DISCUSSION...An area of moderate to heavy snow has developed within
   a deformation band across south-central and eastern Minnesota this
   morning. Temperatures are marginal with observed temperatures around
   32F to 34F within the snow band and ground temperatures well above
   freezing. However, webcams across south-central Minnesota show that
   snowfall rates are heavy enough for accumulation. Continued
   accumulation is expected where snowfall rates are the heaviest
   through early afternoon. Precipitation rates will start to lessen by
   mid-afternoon as the surface low starts to occlude. Thereafter,
   while snow may continue to fall, more significant accumulation is
   less likely due to the slower rates over warm ground temperatures.
