Surface & Upper Air
Surface Analysis
January 22nd 8:15 PM EDT: The Cyclone began its rapid evolution on the Carolina coasts. Courtesy: WPC's Surface Analysis Archive |
January 23rd 5:27 AM EDT: The cyclone worked its way North on the East coast. Courtesy: WPC's Surface Analysis Archive |
January 23rd 11:39 AM EDT: This is when mass accumulation of snow began in South Central PA. Note the occlusion that took place in the cyclone. Courtesy: WPC's Surface Analysis Archive |
Surface Wet Bulb Temperature (SWBT)
1/22 7PM to 1/23 7PM EDT: Note the very prevalent cyclogenesis. The low pressure cyclone deepened dramatically as it moved North up the East coast. This is classic Nor'easter behavior. Surrounding isobars tightened up, allowing for the wind speeds that justified the blizzard title. Strong Northeasterly flow that punched moisture into regions of lower heights was the perfect formula for dense and wet snow. Courtesy: SPC Mesoanalysis Archive |
