I checked the forecast for NorthHampton and Williamstown, and unfortunately the arctic temperature are expected to lose much of their impact by the time they get that far east--a relatively mild 5 to 10 below zero in your area, which may not be cold enough to kill hemlock wooly adelgid. Our high temperatures have been well below zero for the last three days and will be today as well. The coldest overnight temperature report I have found in MN so far is 48 below zero in Babbitt, but I have not seen the reports yet for Tower and Embarrass, which usually have the coldest temperatures. I'll bet they made 50 below last night or might tonight. I was on public radio this morning talking about how this prolonged fairly deep cold spell, although not quite the magnitude of historic cold waves in Minnesota, will nevertheless be a blow to populations of insect pests in Minnesota Lee > > --~--~---------~--~----~------------~-------~--~----~ Eastern Native Tree Society http://www.nativetreesociety.org You are subscribed to the Google Groups "ENTSTrees" group.
