This all began on January 21st. An Arctic High was located over the region, bringing unseasonably cold air into the Mid-Atlantic. At the same time, an area of low pressure was developing along the Texas-Louisiana border. By the next day, the low had moved off the Georgia coast. By that afternoon, it had moved into the DC metro area… with snow becoming extremely heavy across the entire region by early evening.

By the 23rd, the system had moved off shore-- but was still producing snow at rate of over an inch per hour.
