ROANOKE, Va. – By technical definition (three consecutive days or more of 90° heat), the Roanoke Valley is going through its first heat wave of 2023. The heat continues into Thursday.
Any storms - similar to Wednesday - will be very isolated, as there’s nothing around to trigger our heat and humidity.
Come Friday, the heat and humidity will be the same. This time, there will be a weak front passing through the region. This will fire off scattered afternoon and evening storms. Most of these will form along and east of the Roanoke Valley.
We’ll be in between weather systems on Saturday, resulting in only an isolated storm chance during typical hours.
A better chance of storms arrives Sunday as moisture levels increase. We won’t be quite as hot either.
