Virginia Weather Forecast: Heat Wave Timeline to 'Feels Like' 107 Degrees

Sunday will be another hot day across the region, but the real threat will come Monday, when we could see record-breaking temperatures.

Before this heat wave is over, we'll see the heat index, or "feels like" temperature, reach 107 degrees, according to the National Weather Service.

If the actual temperature hits 100 degrees, it would be the first time since July 2012, according to The Weather Channel.

For Sunday, the main threat is coastal regions to our north and south.

But the D.C. and Baltimore areas won't get the same break on Monday.

The heat index will climb to 100 degrees by 10 a.m. and reach 107 degrees for most of Monday afternoon.

Here's a timeline for the "feels like" temperature, through Monday:

Sunday

11 a.m.: 93 degrees

noon: 97 degrees

2 p.m.: 99 degrees

3 p.m.: 98 degrees

7 p.m.: 96 degrees

8 p.m.: 94 degrees

Monday

9 a.m.: 91 degrees

10 a.m.: 100 degrees

11 a.m.: 103 degrees

noon: 106 degrees

2 p.m.: 107 degrees

5 p.m.: 105 degrees

6 p.m.: 103 degrees

7 p.m.: 101 degrees

8 p.m.: 97 degrees

Temperatures will cool slightly Tuesday, but it'll be some time before we feel "cool," according AccuWeather Meteorologist Kyle Elliott.

"With no strong pushes of cool air from Canada on the horizon, people from the mid-Atlantic to the Deep South can expect virtually no relief from the high heat and humidity," Elliott said.
