#ROCKY MOUNTAIN POWER OUTAGES SERIES#

By April 29, a ridge of high pressure centered over the Atlantic Ocean, this helped focus high levels of atmospheric moisture rising from the Gulf of Mexico along the front, causing immense clusters of heavy rain and thunderstorms to slowly progress eastwards – also known as thunderstorm training. A few tornadoes touched down, including an EF2 that caused considerable damage near Cameron, Oklahoma. Shortly afterwards, thunderstorms erupted along the stationary front, which required the National Weather Service to issue some severe weather watches. By 21:00 UTC, a surface low with a central pressure of 1,003 millibars (29.6 inHg) developed in central Kansas. On April 28, a stationary front drifted across the central United States, associated with cloudiness and showers. Together, the two tornadoes caused four deaths and many injuries. The most significant and damaging events of the storm unfolded late on April 29, when two large, long-tracked, and powerful wedge tornadoes struck areas near Canton, Texas, the strongest being an EF4. Up to 3 feet (36 in) of snow fell on the cold side of the system, and up to a foot of rain fell in and around the central parts of the nation. It formed out of a disturbance in the Southwestern United States on April 28, and caused significant impacts, including a heavy snowstorm in the Rockies, and other types of severe weather.
