   Valid 021834Z - 022230Z   
      
   SUMMARY...Heavy snowfall rates between 1-2 inches per hour remain   
   likely across southern New York into portions of New England this   
   afternoon.   
      
   DISCUSSION...Latest radar mosaics show the development of a snow   
   band across portions of south/southeastern New York in response to   
   strengthening frontogenesis between the 925-850 mb levels across the   
   Mid-Atlantic/New England coast. Surface observations and web cams   
   under this band are reporting visibility reductions between 1/4 to   
   1/2 mile, which given weak winds across the region, are likely being   
   driven primarily by moderate to heavy snowfall rates. Broad-scale   
   ascent ahead of an approaching upper wave and more focused mesoscale   
   ascent within the warm advection branch of an intensifying low-level   
   cyclone (augmented by frontogenetical responses) will remain   
   favorably phased through the remainder of the afternoon over the   
   greater New England region. This will continue to favor widespread   
   light/moderate precipitation and the maintenance and/or development   
   of heavier precipitation bands. Consequently, snowfall rates between   
   1-2 inches/hour will remain likely for areas north of the surface   
   freezing line. Nearly isothermal temperature profiles from the   
   surface to around 850 mb suggests that areas near the surface   
   freezing line may continue to see rapid fluctuations in   
   precipitation type between snow, sleet, and potentially freezing   
   rain.
