    Ended up using this to be the 'last Thursday' part.  Not sure if ther is a more elegant way for it but it does the job.

    case
    when DAYOFWEEK(CURRENT_DATE())=1 then CURRENT_DATE()-3
    when DAYOFWEEK(CURRENT_DATE())=2 then CURRENT_DATE()-4
    when DAYOFWEEK(CURRENT_DATE())=3 then CURRENT_DATE()-5
    when DAYOFWEEK(CURRENT_DATE())=4 then CURRENT_DATE()-6
    when DAYOFWEEK(CURRENT_DATE())=5 then CURRENT_DATE()-1
    when DAYOFWEEK(CURRENT_DATE())=6 then CURRENT_DATE()-2
    when DAYOFWEEK(CURRENT_DATE())=7 then CURRENT_DATE()-3
    end
