Lake Effect Snow

     As stated the past few days , Lake Effect snow should impact some areas. The band is starting to re-intensify and should continue to increase in coverage. The band has been rather weak , because of high wind shear. This is now changing , but this has limited the snowfall amounts thus far.


     Here is the placement of the two main bands. The most southern one is very weak , but should strengthen. The band near Syracuse should be the main band and will be the strongest, will contain snowfall rates over 2in/hr. Some areas may still see totals pushing 14-15in, but in general snow totals out side of the persistent band should be lower than forecast due to the increased wind shear early this morning

 
      Another important piece, which is just starting is an Upstream Connection. Here is the Visible Satellite Imagery, this shows clouds and other important features. The upper lakes help add moisture to the Air which then gets even more moisture from Lake Ontario. This is something to watch , because as we head into the evening bands usually become stronger because the  air becomes colder and increase the Lake to Air temperature difference.
