Isolated pop up showers develop around the middle of the day.
These continue to grow through the afternoon with increasing coverage. Some of these storms could pack a punch, and feature gusty winds and small hail.

Excessive heat warnings are in place for Halifax, Charlotte, and Appomattox counties until 8 PM tonight. Excessive heat watches are in effect for the Roanoke, Southside, and Lynchburg Zones until 8 PM tomorrow night.
Tomorrow showers and storms will pepper the region as moisture is moved into our atmosphere. This will give us some slight relief from the heat.

Sunday Morning Update
Temperatures will climb into the 90s and 100s Monday afternoon, but will feel even hotter...
A large area of high pressure and a very warm airmass are situated over the eastern half of the Country. Hot and humid conditions will exist for much of the week.
Here is a look at temperatures across Southwest Virginia Monday afternoon.
The level of humidity will be high. High levels of humidity make it harder for our body to sweat and cool off. This is why it is crucial to stay hydrated and cool during heat wave events.
When you factor high temperatures and humidity together, you get the heat index or real feel. Most of the area will be feeling well above 100°.
This large area of high pressure will keep in place for several days. Heat impacts will be felt across the Northeast, Mid-Atlantic, Southeast, South, and Upper Midwest.
One of our biggest concerns during extreme heat events is heat exhaustion. Here are some tips to mitigate.
Remember, this will be a multiday event. The hottest time of the day will be during the afternoon hours.
A reminder that if you are hot, your pets are likely hot. Please take of yourself, others, and pets during this event.
