It is unclear what is meant by the average risk. A large portion of the Mississippi and Ohio valleys was under a 2% or greater risk for tornadoes. About half of that area was under a 5% risk.
Yes. The Storm Prediction Center has mentioned the potential for a few strong tornadoes.
Potentially. Much of north North Carolina is at a risk of severe thunderstorms, and tornadoes have been mentioned as a threat for that day.
It is too early to tell for sure, as there is always uncertainty in these outlooks, but the fact that there is a moderate risk outlook and the potential for tornadoes has been mentioned, a few strong (EF2+) tornadoes may be possible. However, the oulook states that the primary threat is expected to be hail.
It is not likely. Currently the moderate-risk outlook has been issued for hail, for which the SPC does not issue high-risk outlooks. Only slight-risk outlooks have been issued for wind and tornadoes.
In general, Idaho is at very low risk for tornadoes Boise, ID , in particular, had their largest tornado in 1956, it is considered a low risk area for tornadoes..

Yes, tornadoes can occur in Illinois. Illinois experiences an average of 54 tornadoes per year, making it one of the states with a higher tornado risk in the United States. Tornadoes can happen in any state given the right weather conditions.
The SPC did not include a hatched area for tornadoes for March 25, which would indicate a 10% or greater chance of strong tornadoes within 25 miles of a given point. In fact, only a 5% risk area was defined for tornadoes overall. In most cases, this would suggest that strong tornadoes are unlikely, but it does not rule out the possibility. That at least one strong tornado (EF2 or EF3 by the looks of the damage) occurred shows that there was indeed such a risk.
Probably not, though it probably can't be ruled out either. Typically, when a moderate risk outlook has been issued, the previous outlook had a relatively large area under a higher degree of slight risk (such as a 10% outlook for tornadoes). The 10% tornado outlook in this case is not that large, but again, an upgrade to the outlook probably can't be ruled out. That said, even if a moderate risk outlook is not issued, the SPC has mentioned the potential for strong tornadoes, and violent tornadoes have occurred under similar circumstances. SPC outlooks should be taken with a grain of salt, as a slight variation in weather conditions can make a significant difference in how an event will play out.
The lowest risk of tornadoes is generally in regions located near the equator, such as the equatorial regions of Africa, Asia, and South America. These areas experience less tornado activity due to the lack of significant temperature variations and weather patterns conducive to tornado formation.
Yes. The outlook for April 14, 2012 mentioned some risk for violent tornadoes, referring to tornadoes of EF4 and EF5 intensity.
