Statistics show May was the peak month for tornadoes in Arkansas over a 30-year period. Numbers released Thursday from the National Weather Serviceâs Storm Prediction Center showed May as the month with the greatest number of tornadoes from 1981 to 2010. April came in second and November was third.
Tornadoes, however, can occur almost anywhere in the United States, including west of the Rockies and east of the Appalachians. Supercell tornadoes are most likely to occur between 3:00 and 9:00 in the evening. Current tornado warnings have a 13-minute average lead time and a 70% false alarm rate. Tornadoes have been known to destroy houses, but leave light objects like plates, glasses, lamps, and even paper undisturbed on tables.
