ROANOKE, Va. – Update
The Weather Authority Alert Day issued for Friday, July 5 has expired.
4:10 PM Update
Heat advisories have expanded west this afternoon and now include the Roanoke Valley. Again, feels like temperatures will be in the triple digits for some this afternoon/evening. The advisory is in effect until 8:00 PM Friday night.
Today’s Weather Authority Alert Day is two-fold due to the impacts of dangerous heat and strong to severe storms in the late afternoon.
Temperatures in parts of the Southside and Lynchburg areas could approach the 100 degree mark today, with heat indices above 105 expected from these high temperatures and significant humidity.
Most of the region will have temperatures in the mid 90s, but again, when combined with the humidity, will feel a lot hotter. Be mindful of your pets as well if you’re taking your furry friend out for a walk, as concrete and asphalt could reach scorching temperatures capable of burning paws.
The greatest heat index values can be found to the east, with a Heat Advisory in effect for the day as well for several counties in the Lynchburg and Southside zones. Be sure you stay hydrated, take breaks in the shade, and stay cool any way possible. Heat related illness can sneak up quickly, and anyone is susceptible to it.
The other part of our Alert Day is the risk of strong to severe storms in the afternoon and evening. Storms will initially fire up in the afternoon, but will strengthen throughout the day from the significant heat and humidity. As we get into the evening hours, frequent downpours and damaging winds are likely as storms pass through the area. Torrential rain could create instances of flash flooding, particularly in urbanized areas.
The SPC has put us under a slight risk (2/5) for severe weather. The greatest threat is damaging winds capable of knocking over trees and powerlines.
It’ll be important to secure any loose belongings outside, as they could easily blow away in gusty winds.
