It's special because April has the highest number of tornado fatalities of any month, though strangely May has the highest number of tornadoes.
Tornadoes usually occur in spring and early summer while hurricanes usually occur in summer and early fall. However, tornadoes can occur at any time of year, and out of season hurricanes have occurred as well.
That is difficult to determine. The highest winds ever recorded in a tornado were measured on May 3, 1999 near Oklahoma city. However, most tornadoes don't get their winds measure so its entirely possible, even probably, that others were stronger. Candidates include the Tri-State tornado of March 18, 1925; the Xenia, Ohio tornado of April 3, 1974, and the Jarrell, Texas tornado of May 27, 1997.
Weak tornadoes are those rated EF0 or EF1 and cause damage that is considered mils to moderate. Typical EF0 damage includes some shingles and siding stripped from homes. Gutters and awnings may be taken down as well. Tree limbs will be broken and weakly rooted trees may be toppled. Typical EF1 damage includes severe damage to house roofs, and broken windows. Barns and outbuildings may collapse. Trailers can be overturned or very severely damaged.

There are many ways in which tornadoes can differ. They can differ in wind speed, winds may range from 65 mph to over 300 mph, though the lower wind ranges are more common. They can differ in diameter, ranging from less than 10 yards wide, to the record size of 2.5 miles. Distance traveled can range from several yards to over 200 miles (the record is 219 miles). Tornadoes can range from being nearly stationary to traveling at over 70 mph. Tornadoes differ in how long they last, ranging from a few seconds to over 3 hours. Tornadoes can even differ in structure. Some tornadoes are a simple single vortex while others have a downdraft moving down the center, this can produce multiple smaller vorticies within the funnel. All of these factors combined with where and when a tornado hits influences how much damage occurs and how many deaths and injuries there are.

It is unusual. The months of April, May, and June are generally the most active. Looking at those 3 months in the years 1990-2011 shows that only 4 of them had 400 or more tornadoes: May of 2003 with 542 tornadoes May of 2004 with 509 May of 2008 with 462 April of 2011 with a record 758 tornadoes. June of 1992 and May of 1999 came close, with 399 and 392 tornadoes respectively.
The record for tornadoes in a single month (at least for the U.S.) is April of 2011 with about 750 tornadoes. Tornado activity usually peaks in May.
The three most active months for tornadoes in the United States are April, May, and June.
Tornadoes usually form in "Tornado season", or somewhere in the spring. The 3 months are April, May, and June.
