• All forecast times are displayed in GMT. It is 4 hours after the Eastern Time (ET).
  
• The forecast system is based on WRF ARW V3.3.1 and the Penn State (PSU) EnKF with 60 ensemble members for data assimilation.
  
• There are three triply nested WRF forecast domains with grid spacing of 27km, 9km and 3km, respectively.
  
  
• ANPS: PSU 3-km forecast with no airborne Radar assimilation deterministic forecast
  
• GFS: NCEP Global Forecast System
