Tracking lingering smoke, summer storms Tuesday

Air quality won’t be as poor as it was Monday afternoon

ROANOKE, Va. – Storms Monday evening helped to improve the air quality in parts of the New River Valley, Roanoke Valley, Highlands and Lynchburg area.

That said, some smoke may linger in areas along and south of US 460 Tuesday, leading to ‘Moderate’ air quality levels or levels considered ‘Unhealthy for Sensitive Groups.’

At the same time, we’re tracking a boundary that could trigger isolated morning showers. Once the heat and humidity of the day get going, additionally scattered showers and storms will fire up after 3 p.m.

Scattered storms re-develop Tuesday after 3 p.m.

These chances last into the night as a cluster of storms dives from west to east.

Once again, that leaves behind a boundary for more scattered activity Wednesday. A few of those storms could be on the strong side east of the Parkway.
