The November 26 – December 3, 2019 North American blizzard was a major winter storm from the Rocky Mountains to the Northeast as well as a record-breaking windstorm along the West Coast (particularly California and Oregon).
Moving ashore on the night of November 26 near the Oregon/California border, the storm produced a record low pressure reading of 973.4 millibars (28.74 inHg) in Crescent City, California.
The combination of cold air, moisture and high winds produced a wide swath of blizzard conditions from Colorado through western South Dakota, including the Denver area.
As the first major winter storm of the season in the northeast, it dumped 22.6 inches (57 cm) of snow in Albany, where it was the heaviest snowfall since the 1993 Superstorm.
[2] Over the following three days it merged with the subtropical jet stream as it trekked slowly eastward over the Rockies, High Plains and Midwest.
Following the recent drought and wildfires, the ground had reduced ability to absorb rainwater and so the NWS warned of the possibility of flash floods and debris flows.
Freezing levels fell below 3,000 feet (910 m), meaning that high elevation suburbs of Los Angeles like Palmdale and Victorville received accumulating snow.
The snow was disruptive to Thanksgiving travelers, as it weighed down and snapped tree limbs and closed I-5 at Parker Road and the Grapevine.
[7] In Duluth, Minnesota, 21.7 inches (55 cm) of snow fell at the airport, where wind gusts frequently exceeded 35 miles per hour (56 km/h), meeting blizzard criteria.
[10] In Albany, 22.6 inches (57 cm) of snow fell, making the storm the eighth and fourth-worst overall and for December, respectively, and the most intense since the 1993 Superstorm.
