Spring in the Northeast...get out your shovel!

   It is definitely debatable for whether or not Spring exists in the Northeast, especially after this forecast.  That's right, snow and temperatures in the 30s!! Not very spring-like.
   Wednesday a low pressure system will be moving over the Northeast region.  Currently some snow and mixed precip is moving into southern New York, but it won't be reaching the Rochester area until around 2am.  Current IR satellite images show this system stretching from Montana to Connecticut.  Its currently bringing heavy snow to the Northern Plains region and some severe t-storms and rain to the Midwest.  As this system in the Midwest meets up with another, weaker low pressure system currently in the Virginia/North Carolina region, it will strengthen.  This will occur as the system nears our are and the Great Lakes.
   So what exactly will this mid latitude cyclone be bringing our way? Snow!!! Although majority of the more intense precip will take place south of New York, we will still see a decent amount of snowfall here in Upstate New York.  Both the NAM and the GFS appear to be in pretty good agreement that the Rochester are will see 3-5" of snow with localized areas receiving around 6-8" (i.e. areas closer to the lake).  Areas south of the city could receive some sleet.  This snow will not be the fun fluffy stuff, but rather the ugly, heavy, wet snow.  After this system temperatures will remain in the mid 30s for the res of the week.  Things should hopefully warm up again later next week.
     I will attempt to update this forecast tomorrow! In the mean time get that shovel out again! This is Rochester!
