Recap of the January 1st - 3rd Snow Event

A deep upper level trough of low pressure which set up over the eastern U.S. brought an arctic outbreak complete with a light snowfall to eastern Kentucky from Tuesday January 1st through Thursday January 3rd, 2008.  The surface chart below and radar imagery shows the strong high pressure over the Plains and low pressure over the Canadian Maritimes.  This setup produced strong northwest flow bringing Great Lake moisture down from the north.   Several upper level disturbances, and the upslope winds, worked on this moisture to produce a light snowfall for the area.

Snowfall amounts varied quite a bit from location to location due to the showery nature of the snow.  The highest amounts generally fell over the higher terrain near the Virginia border, as is usually the case in a northwest flow upslope snow event, but most locations across eastern Kentucky received an inch or more of snow.  The map below is an estimation of the snowfall amounts from late Tuesday afternoon January 1st through around 7 am Thursday morning January 3rd, 2008.  The map was derived from reports received from area cooperative weather observers and highway garages...
