A slow moving warm front lifted across the middle Ohio River Valley and central Appalachians on the 30th. Additional support was provided by several mid level shortwave troughs and a weak surface low. A high moisture atmosphere was in place, and slow moving showers and storms produced very heavy rainfall through the afternoon and evening. In the areas of heaviest rain, which stretched from Huntington northeastward to near Elkins, 2 to 4 inches of rain was common, and several gauges indicated more than 4 fell.  In fact, two gauges around Grantsville measured 5.12 and 5.04 of rain. A second, more localized, area of heavy rain fell in Tazewell County, VA northward into the headwaters of the Dry Fork of the Tug River in McDowell and Mercer Counties. Runoff from this heavy rain flowed down the Dry Fork of the Tug River overnight causing flooding.
