  • Forecast scripts modified to use NDFD air temps and winds when available instead of ETA air temps and winds.
    • May 15, 2007
  • ice was turned off.
    • Mar 30, 2006
  • Lake Michigan was switched from 5km to 2km. The entire year was rerun using the new grid. Lake Michigan now also includes static river flow.

  • Starting today (0Z, 2/2/05), the GLCFS wave model runs (nowcast and forecast) will take into account the ice cover from the most recent GLSEA. This includes the grib wave files (mapped onto the awips227 grid) I am ftping to the NWS gateway. The waves are dampened as a function of the ice concentration.
