Hi Dave.
I read your "going way back to the 1990s" with both amusement ,as for me
that's not way back, and fear as I remember watching migration "trains"
of blackbirds that went on for hours in the 1950s and warblers really
dripping off of trees in large numbers. Even when stationed in the DC
area
All,
For the past few days there has been an upper level low pressure system
spinning about over the Ohio and Tennessee Valleys. This feature is cut off
from the main polar jet stream current which is flowing across Canada see
