The 1988 Raleigh tornado outbreak of November 28, 1988 was the most destructive of the seven tornadoes reported in northeastern North Carolina and southeastern Virginia between 1:00 AM and 5:45 AM The Raleigh tornado produced over $77 million in damage, along with four fatalities (two in the city of Raleigh, and two in Nash County) and 154 injuries. The damage path from the storm was measured at long, and wide at times. == Synopsis == A surface-level pressure trough was located east of the Appalachian mountains and extended from Maryland to Georgia. A warm front previously located in the coastal plains had moved into the piedmont, separating air with temperatures and dew points in the 50s to the northwest from southeastern air with temperatures in the 70s and dew points in the 60s. A large upper level progressive amplitude trough stretched from the Great Lakes to the Mississippi Gulf Coast, and an also large amplitude ridge was situated over the western Atlantic with an axis extending from Bermuda to the Canadian Maritimes. A subtropical jetstream axis extended from the Gulf of Mexico to the Savannah River Basin. A polar jet stream was located over the Ohio River valley. Positive buoyant energy was estimated at 1200 j/kg over the Raleigh area 〔http://www4.ncsu.edu/~nwsfo/storage/cases/19881128/〕
