ROANOKE, Va. – It’s another muggy start to our Wednesday morning, with temperatures mainly in the 60s. This gives us a head start on the day, as high temperatures reach the 80s in the New River Valley and Highlands and upper 80s to lower 90s in Roanoke, Lynchburg and Southside.

While widespread storms aren’t expected, some pop-up storms will be possible during the near-record heat of the day.

Given the heat, these storms can grow tall and possibly become strong-to-severe. While we don’t expect an outbreak, we’ll have to watch for a few stronger storms between about 1 p.m. and 7 p.m. Wednesday.

High temperature forecast for Thursday, May 27th, 2021

The bulk of any severe weather will stay in the Plains and Upper Midwest Thursday, but this all comes with our next front. Showers and storms will increase late Friday afternoon and linger into the night. Given the moisture and wind around this system, we could see a few strong-to-severe thunderstorms during that time frame. Keep checking back for updates.

Some showers will be left over Saturday, with clouds, cooler air and lower humidity Sunday.

Tracking humidity levels this weekend

It’s not out of the question that we see some patches of drizzle Sunday, with cooler air being wedged into our region.

With lower humidity in place and high pressure taking over, expect Memorial Day to be pleasant. We’ll start out cool - in the 40s and 50s - before temperatures rise into the 70s during the afternoon.
