The North Texas Snowstorm of 2022 was a historic snow event that buried the Southern United States , most notably North Texas, with over 2 feet of snow from January 16 to January 19. It had origins from a shortwave trough extending from British Columbia down to Baja California during January 14-15. A state of emergency was declared for 5 southern states on January 15, with blizzard warnings issued in 2 states. Over 15 million were affected by the snowstorm, including over 2 million who lost power. The storm also claimed 16 fatalities . On the RSI, the storm ranked as ''Category 4 Crippling''.
On January 14, a shortwave trough formed over British Columbia, Canada. During the next two days, it moved southward through the Pacific Coast region. The National Weather Service began monitoring it on the day it formed for possible storm development. On January 15, it became clear that it would soon develop into a storm. Forecasters in the Southeastern U.S. began predicting up to 8 inches of snow in certain areas. On January 16, the trough spawned a surface low over Baja California, a defined-low pressure area. At the time, the minimum barometric pressure was 1,004 millibars. The system then began to track towards the east while frontogenesis took place. As a result of that and other moisture coming in from the Pacific Ocean, rain began falling in Southern California and Arizona, becoming snow in mountainous areas. During the afternoon hours of January 16, the low began to weaken over the mountainous terrain of Central Mexico. However another weakening low pressure system in the Gulf of Mexico began feeding the original low. At that time, forecasters began upgrading their snowfall totals. By the afternoon of January 17, the system had absorbed all of the secondary lows energy while it was located over South Texas and bombogenesis took place . Subsequently, the system moved into the Gulf of Mexico and bombed out to 976 millibars while it was located 100 miles offshore of Houston, Texas. Afterward it began to weaken during January 18-19. By the morning of January 19, the minimum barometric pressure increased to 1,000 millibars as it moved ashore of Florida. After crossing Florida, the system then tracked off the coast of Georgia and the Carolinas, while precipitation totals decreased. It reached the Mid-Atlantic region on January 20 before turning toward the northeast. By January 21, the system had completely left the East Coast of the United States.
