Flash Flood — Jul 18, 2025
A frontal boundary approaching from the north combined with a hot and humid air mass to produce scattered severe thunderstorms across southwest Virginia. Damaging wind gusts from these storms blew down several trees and power lines with one of the trees falling on to a house in Bedford County, and hail up to the size of quarters fell in Bedford and Henry counties.
Flood — Jan 9, 2024
A deep, negatively tilted upper level trough and associated occluded front passed from the central Mississippi River Valley on January 9th toward the lower New England region by the morning of the 10th. Strong southerly wind flow ahead of the upper trough carried deep moisture from the Gulf of Mexico northward into the Carolinas and the lower Mid-Atlantic. Precipitable water values ranged fro...
Flash Flood — Jul 15, 2023
A trough of low pressure was situated from Buckingham County, VA southeast through Alleghany County, NC during the evening of the 15th, while a cold front was advancing eastward across the mountains. A wave of low pressure passing along the front over western North Carolina served to increase low level winds into the 20 kt-25 kt range from the south, tapping into deep moisture. By 8 pm EDT, ...
Flood — Mar 23, 2022
A slow moving cluster of thunderstorms that lasted just over an hour passed near the City of Galax and the community of Fries in the evening of the 23rd. Despite modest instability of 250-500 J/kg of surface-based CAPE, an anomalously-high precipitable water estimate of about 1.2 inches created a healthy environment for strong rainfall rates embedded in convective systems. MRMS FLASH returns w...
Flash Flood — Aug 21, 2022
A warm front, drifting northward from the Carolinas across the lower Mid-Atlantic, triggered scattered thunderstorms with heavy rain. Strong heating during the afternoon supported surface-based CAPE values rising into the 2,000 to 2,500 J/Kg range, while precipitable water values ranged from around 1.5 inches along the Blue Ridge to in excess of 1.8 inches across the central Piedmont of Virgin...
