Above is an image comparing the 2 tornadoes that impacted the city of Tuscaloosa on April 15th and April 27th.

We look back to this day in history, 5 years ago, when a deadly tornado outbreak happened in Alabama. This was a record breaking event, where several people died and numerous people were injured. Only a week and a half later, April 27th would beat the April 15th records by far. This would be the first of two events to produce a tornado in Tuscaloosa. In Tuscaloosa, the April 15th tornado was rated EF-3 and the April 27th tornado was rated EF-4. Several other towns across Alabama were hit twice by these two historic events. Below is information on the April 15th event, put together by the National Weather Service in Birmingham.

April 15, 2011 Tornado Outbreak:
A POTENT STORM SYSTEM AFFECTED A LARGE PART OF THE CENTRAL AND EASTERN UNITED STATES. SIGNIFICANT SEVERE WEATHER OCCURRED FROM THURSDAY APRIL 14TH THROUGH SATURDAY APRIL 16TH. TORNADOES WERE REPORTED IN KANSAS, OKLAHOMA, TEXAS, LOUISIANA, MISSOURI, ILLINOIS, MISSISSIPPI, ALABAMA, GEORGIA AND THE CAROLINAS. ADDITIONALLY…DAMAGING STRAIGHT LINE WINDS AND LARGE HAIL OCCURRED.

NUMEROUS LONG-LIVED SUPERCELLS DEVELOPED ACROSS CENTRAL ALABAMA FRIDAY APRIL 15TH. THESE SUPERCELL PRODUCED CYCLIC TORNADOES THROUGHOUT THEIR LIFETIMES. THOUSANDS OF TREES AND POWER LINES WERE BLOWN DOWN AND STRUCTURAL DAMAGE WAS SIGNIFICANT.

A surface low, which had developed across the Central Plains on Thursday, the 14th, deepened as it moved into the Mid-Mississippi Valley.  In response to this deepening, surface dew points in the middle to upper 60s surged northward into Central Alabama and deep vertical wind shear increased.  By the morning of Friday, the 15th, it was evident environmental conditions were going to be perfect for tornadic supercell development.  The Storm Prediction Center issued the first Tornado Watch for Central Alabama prior to 8 am and supercell development began just after 11 am across central Mississippi.  These storms crept across the Mississippi and dropped multiple damaging tornadoes.  The first tornado warning in Central Alabama was issued at 11:52 am in Marengo County and warnings were issued until 1215 am the next morning.
