2011’S APRIL MAY BE ON TRACK TO BECOME THE WORST APRIL EVER FOR
TORNADOES
During the past 30 years, the United States has averaged 135 tornadoes in April, the
highest number being 266 in 1974 (National Climatic Data
Center)
THE CAUSATIVE STORM: APRIL 14, 2011
CHRONOLOGY
• FROM THE PACIFIC TO OKLAHOMA, TO ARKANSAS, TO MISSISSIPPI AND ALABAMA, TO NORTH CAROLINA, AND POINTS IN BETWEEN.
This storm system, which first developed over the
Pacific, intensified when it got to the central Plains on
Thursday where the dry western air collided with the
warm humid air from the Gulf of Mexico.
From there, the storms developed as expected over
Oklahoma, with double vortex funnel clouds in some
cases..
Overnight, the storms merged into a fast-moving front
crossing Arkansas and into the Mississippi River Valley,
drawing fuel from daytime heating, before moving on into Mississippi and Alabama and
the Appalachians on Saturday.
Then the storm strengthened again as a
result of the daytime heat for the third day of tornadoes that hit North Carolina hard..
