COASTAL AREAS: 6 PM TO MIDNIGHT
The Storm Prediction Center has areas along and east of I-95 in a SLIGHT RISK (Level 2) for severe weather on Wednesday. Some storms could be severe with damaging wind gusts.
The NAM 3km (North American Model) shows thunderstorms developing across the Shenandoah Valley early Wednesday afternoon, with additional development east of the Blue Ridge.
The concern is there for these storms to form one strong to severe line as they push across the Piedmont and into the I-95 corridor, near the evening rushhour. Storms will eventually move to the coastline by late evening.
While damaging winds (60 MPH) is the primary threat, the risk for torrential rain continues, as this remains a very humid and soupy environment. There could be a period during the early to mid-afternoon where flash flooding needs to be monitored, especially across the Shenandoah Valley. Storms will be slow-movers at first, but will gradually pick up speed as they head towards the east by evening.
