Daily briefing: Extreme heat continues for South

Low risk for isolated storms across the Northeast and the Northern Plains. The big news will continue to be the dangerously hot temperatures across the Plains and Southeast. All of this, along with today's tropical outlook, is included in the daily briefing, published every weekday at 5 a.m. ET.

A high-pressure system will dominate much of the southern central plains and parts of the southeast to start the week. The remnants of the moisture we were monitoring over the Gulf last week have finally moved inland, and better conditions now dominate the southern Plains. The temperatures will remain warm, especially across Texas, as this high-pressure system sets up camp and brings moisture from the Gulf, making the temperatures feel hotter than the thermometer indicates. Triple-digit Heat indices are expected for Monday.

Across the Carolinas, there’s a weak low-pressure system affecting the region. Still, it will continue to meander around and likely increase the rain chances across northern Florida once again for the middle of the week.  Temperatures will be dangerously hot across the Southeast on Monday, with regions like Columbia, S.C., likely to surpass 100°F. Atlanta will also approach triple digits on Monday afternoon. Much of the week will remain warmer than average, with temperatures 10 to 15° above normal across much of the East, extending into the Northeast. A cool-down is expected toward the latter part of the week, especially across the Northeast, when the highs will drop into the upper 70s. The low to mid-90s will stay put across the Southeast, but at least they’ll be closer to normal for this time of year.

For the West, a series of low-pressure systems will continue to affect much of the region. These storms will bring more clouds and shift the winds, allowing temperatures to stay slightly below normal at the start of the week. However, as the week progresses, especially toward the middle, the wind will shift, and temperatures will remain between three and eight degrees below normal for this time of year.

As for storms, we are not currently monitoring any significant severe storm threats across much of the United States. There could be a few isolated showers and storms pushing across upstate New York, as well as another cluster of storms across the northern Plains. This will be due to one of the low-pressure systems that will swing the moisture coming in from the Gulf, bringing instability and developing scattered showers and thunderstorms, especially during the afternoon hours.

Across the tropical Atlantic, we’re not expecting any tropical storm formation to start off the week.

Do you know our app that provides an Air Quality Index for your city? Summers can bring oppressive heat, but when a high-pressure system sets up camp, the sinking air is not only extra hot; other contaminants can also sink to the surface, affecting air quality. Check it out, here.
