  1. Rates here are good but not spectacular. Nowhere near enough to overcome the pavement. With the looks of things I think I'll be lucky to get 2", more likely about and inch and a half which will bust way lower than the 5-8 LWX has. Not a big deal but the speed of this and lower QPF ended up getting us here. Trends mean something and just like Monday, it's gonna bust low. 

    On to the next, if there is one.

  2. Meso discussion from SPC, would seem to support there's issue with drier air.

       Areas affected...Northeast West Virginia to western New Jersey
    
       Concerning...Heavy snow 
    
       Valid 170333Z - 170730Z
    
       SUMMARY...A swath of moderate to heavy snowfall will continue to
       spread east across parts of the Mid-Atlantic over the next several
       hours.
    
       DISCUSSION...A swath of moderate snowfall continues to spread east
       from the upper OH River Valley region into the Mid-Atlantic based on
       recent regional reflectivity composites. Transient organized snow
       bands continue to be observed within this broader zone, resulting in
       visibility reductions from 1/2 to 1/4 mile and steady snowfall
       accumulations based on recent snow reports from the region.
       Favorable phasing of synoptic ascent ahead of the approaching
       shortwave trough and strong isentropic and frontogenetic lift within
       the 925-700 mb layer, which has been driving this activity so far,
       is expected to persist as the system pushes towards the East Coast
       over the next several hours. Latest forecast guidance depicts
       reasonably high probability in snowfall rates between 1-2 inch/hour
       across portions of the Mid-Atlantic region (and possibly as far east
       as the NJ coast) through 08 UTC. Based on observed trends, this
       depiction seems fairly reasonable. One caveat is a lingering
       warm/dry layer below 850 mb sampled by regional 00 UTC soundings and
       noted in surface observations across northern MD, southeast PA, and
       into western NJ, which may limit snowfall rates in the near term.
       However, a combination of evaporative cooling and persistent
       mesoscale ascent along the warm frontal zone should support adequate
       low-level saturation/cooling to allow for moderate to heavy snowfall
       in the coming hours.
