That is, just because a SLGT risk is forecast does not necessarily mean that the thunderstorms within the risk area will be slightly severe. This is because the synoptic situation producing the violent tornadoes may be confined to a relatively small area. Another SLGT risk area may cover several states in which only one or two tornadoes may develop. Some HIGH risk situations are expected to result in a large number of severe reports, but not necessarily tornadic or extreme in magnitude. Remember that almost any thunderstorm can, at some point in its lifetime, produce severe or nearly severe weather .
Any thunderstorm can kill.
SPC severe weather outlooks, though, are keyed to the well-organized severe weather events most capable of damage and injury. Convection of this type, and isolated severe storms with marginal intensities or short durations, will likely not be included in a risk area. When an unusually dense or large area of marginally severe reports is anticipated, though, the area of concern will probably be included in a SLGT risk. General thunderstorm outlooks are meant to be guidance to local forecasters to alert them to the possibility of more than very isolated or brief thunderstorms in or near their areas. Also, the lack of a severe risk within a general thunder outlook does not imply there will be zero severe thunderstorms.
