Almost 5 years ago a massive outbreak of tornadoes took place in the Southern, Midwestern and Northeastern United States. This week I will look back at the events leading up to this outbreak.
The month of April had already been very active when 363 confirmed tornadoes occurred between April 25 and April 28.
Despite warnings that started one week ahead of the event, over 300 people were killed, with more than 2000 being injured.
SPC Day 4-8 Outlook of April 20, 2011:
PRELIMINARY THINKING IS THAT A MORE WIDESPREAD/ MULTI-ROUND SEVERE THREAT MAY EVOLVE THROUGH DAYS 6-8 MONDAY/TUESDAY/WEDNESDAY FROM THE SOUTHERN PLAINS EAST-NORTHEASTWARD INTO THE MIDWEST/MS RIVER VALLEY
Some of the tornadoes were so strong that even people taking proper shelter lost their lives. Thunderstorms on the morning of April 27 caused massive power outages, leaving large parts of the population without radio and TV when the strongest tornadoes struck later that afternoon.
Meanwhile, for 2016, something seems to be brewing for April 27/28 as well with SPC mentioning the possibility for a severe weather event with tornadoes, large hail and damaging wind for parts of Texas, Oklahoma and Kansas.
