| Episode Narrative | A storm system moved from southern California into the northern Rockies and northern Plains. Very stable conditions ahead of the storm system created several days of very dense fog from the 18th through the 22nd of January. This fog created significant delays of commercial and general aviation flights, as well as emergency medical flights having to be grounded. The freezing fog and rime ice, and some light freezing rain accumulated on power lines, causing the lines to snap starting on the 20th and 21st of January. As the storm approached, snow quickly spread from south to north across the area on the afternoon of the 22nd. When the main cold front finally moved through late on the 22nd and the 23rd, the winds switched from the east to the north and northwest with speeds from 25 to 40 mph, resulting in blizzard conditions. Widespread road closures and whiteout conditions kept power crews from being able to restore power, and many residents were without power until January 25th and 26th. Snowfall measurements were difficult to obtain east of Valley and Garfield counties due to the strong winds. |
| Event Narrative | Freezing fog lasted for four days, causing commercial and general aviation delays and cancellations. |
