The latest 12z NAM model guidance is just coming in, and is
certainly still on board for heavy wet snow potential later
tonight within and near the current winter storm watch area. A
quick look indicates it is trending stronger with the coastal
low and a bit colder, with more dynamic cooling and heavier
precipitation (snow) within a deformation band along the I-81
corridor and points east....lingering into Friday morning. Will
wait to see the rest of the 12z guidance before making any
changes to the current winter weather headlines. These trends
make sense as the coastal system is already looking very well
defined, with a baroclinic leaf and developing comma head on the
latest GOES-E hi-resolution 10.35um infrared satellite loop.
Another shortwave which will add energy to the system is evident
over Central Indiana at this time, and the final piece of
energy will rush in from southern Canada on Friday to further
strengthen the system over New England. This is a complex
weather system, with the potential to produce large amounts of
precipitation (and snow) across our area.
This is the only reason I don't go postal when you guys South and Easy of me get the coastal storms while we smoke cirrus up here in Clarks Summit! Love the October/November and March/April elevation events.
