It seems that America’s tornado drought is not going to last for longer and if we're getting any luckier then this might just end as early as this weekend. The potent weather system is slowly moving towards the Mississippi River Valley and this is expected to kickstart a set of a severe weather outbreak which will encourage thunderstorms capable of producing tornadoes through Saturday, Sunday and Monday. 2014’s tornado tally is currently residing in record low terroroty but if this onset of crazy weather does hit for real then this potential tornado outbreak would boost 2014’s tally.
The chief of operations at the Storm Prediction Center in Norman, Okla., Bill Bunting, has revealed to Mashable that the elements which need to be present for a severe weather outbreak are likely to make their appearance from Saturday in the High Plains states. Some of the elements which trigger the fierce weather include strong low-pressure area in the upper atmosphere because this causes the the development of a surface low in the Plains, as well as abundant low-level moisture and winds that vary in speed and direction with height. To be more precise in this weather explanation, the counter-clockwise circulation around the surface low is going to attract the moisture from the Gulf of Mexico northward and this will be coupled with the strong winds at altitudes of about 10,000 to 20,000 feet above ground level which give rise to the wind shear which is necessary for a tornado to form.
According to Bunting, it is time that people from Omaha to New Orleans start keeping a close check on the weather and should start preparing for shelter. “We are on track for at least a 3-day round of severe weather,” he said. “It’s difficult to say at this time just how significant” of an event this will be, Bunting said.
