Winter Forecasting Problems

• Heavy snow - amount, location, duration
• Icing - freezing rain, ice pellets, fog
• High winds - blowing/drifing snow, wind chill
• Lake effect snow
• East coast "bombs"
• Cold air damming
• Orographic influences

Significant Satellite Features

• Jet streaks/dry slots
• Vorticity maxima
• Deformation zones/shear zones
• Subsidence regions
• Baroclinic leaf (cyclogenesis)
• Convection in areas of WAA/isentropic lift/CSI
• Cold cloud top regions
• Cloud phase (glaciation)
• Moisture return/moisture plumes
• Snow pack/ice pack boundaries
