High pressure is gradually weakening while moisture is increasing, allowing a rain threat to return to the region. Daytime heating along with additional moisture will be the driving factors for developing showers and storms favoring the mid to late afternoon hours for Tri-Cities. Storms will initially develop over the Blue Ridge Mountains where the air rises quicker. Showers and storms that develop will lead to additional showers and storms through the afternoon and evening hours, drifting northward in and around the Tri-Cities. It will not rain everywhere and not all day long, so scattered really is the best description of the activity today.
Late Week Outlook
Additional showers and storms will be scattered Friday with warm summer-like conditions. A few heavy downpours, gusty wind and small hail will be possible as well.
A stronger storm system is expected to arrive Saturday, with widespread rain and storms more likely Saturday afternoon and evening. With a higher storm risk Saturday, there could be a few strong to severe storms late in the day.
