   SUMMARY...Heavy lake-effect snow bands will continue through the   
   morning. Snow rates may approach or exceed 1-2 inches per hour on a   
   localized basis.   
      
   DISCUSSION...Cold cyclonic flow associated with a deep low over   
   western Quebec has generated several lake-effect snow bands over the   
   Great Lakes region. In particular, multiple snow bands are affecting   
   northern Lower MI this morning, with some apparent upstream   
   connection to bands across central Upper MI that are emanating from   
   Lake Superior. The KAPX and KMQT VWPs depict little change to the   
   low-level wind field over the last several hours, and guidance   
   generally suggests this northwesterly flow regime will remain   
   relatively unchanged through the remainder of the morning. This   
   should allow ongoing bands to persist, while some cooling aloft   
   (with 700 mb temperatures dropping to near/below -20 C) may   
   gradually increase snow-to-liquid ratios with time. Snow rates of   
   1-2 inches/hour (locally greater) will be possible within these   
   bands, especially if a dominant single band can develop. Wind gusts   
   of 30-45 mph combined with the locally heavy snow rates will result   
   in significant visibility reductions in and near the strongest   
   bands.
