This Hazardous Weather Outlook is for portions of southwest North
Carolina...east Tennessee and southwest Virginia.

.DAY ONE...This Afternoon and Tonight

Strong to severe storms will be possible this afternoon and
evening. The primary threat will be damaging wind gusts.
Additionally, localized flash flooding is possible, especially in
areas impacted by stronger storms the previous days. Flooding of
small streams, ponding of low lying areas, and street flooding are
all possible.

A heat advisory has been issued for this afternoon as well. See
product for additional details. If spending any time outside, take
frequent breaks in the shade and stay hydrated.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday

...A risk of severe storms exists for Thursday and Friday with
increasing coverage of Thunderstorms through the week...

Thunderstorm complexes will continue to move across the area for
Thursday and Friday. Some of these storms will likely become
severe with the main concern being damaging winds. Timing of the
these storm complexes is uncertain but confidence is high that
some severe weather will occur.

Besides the damaging winds, these storms will also produce
torrential rains with localized flash flooding possible. Flooding
of small streams, ponding of low lying areas, and street flooding
are possible.

Heat advisories may be needed again for Thursday and possibly
Friday across the central and southern Tennessee valley. Heat
indices of 105 to 108 degrees are possible.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed for today through Friday, mainly
during the afternoon and evening hours.
