Peter Forister, NOVA Storm Chasing
Denver Murray, Virginia Weather Action
Since our previous update Monday evening, the storm risk has migrated southward. However, this is still a serious situation for Southside Virginia and portions of Hampton Roads. The strongest storms will be along and south of Highway 460 where multiple supercells are expected to develop with damaging winds and isolated tornadoes. Further east, along I-95, strong storms with damaging winds will be the greatest threat, but an embedded tornado can not be ruled out.
Dynamics NORTH of Interstate 64 will be severely limited by ongoing clouds and rain. Areas impacted by drizzles this morning will have *much* lower chances for storms this evening. However, south of the rain, cape levels are expected to exceed 4000j/kg and shear will be 30-40kts through the bulk of the effective layer. These dynamics are more than enough for numerous strong storms starting in the mid-afternoon.
FUTURE RADAR: THIS AFTERNOON & EVENING
FUTURE RADAR: US Route 360 & 460 SOUTH to US 58 VA/NC will be the focus area from 2 PM through 10 PM. Another area of storms will develop after 5 PM across Southwest Virginia. Damaging wind gusts and isolated tornadoes are the main threat. #VAwxPosted by Virginia Weather Action on Tuesday, August 13, 2019
