Seven-Day Outlook: What's Coming for the Northeast, South, and Plains

A volatile week of weather is taking shape across the eastern two-thirds of the country, driven by a strong cold front pushing southeast out of Canada and colliding with the stubborn heat dome that has dominated the South for much of July. Here is a region-by-region breakdown of what to expect through next Monday, July 28.

NORTHEAST: Relief is on the way. After a sticky start to the week — highs of 91°F in New York, 89°F in Boston, and 93°F in Philadelphia on Monday and Tuesday — the approaching front will sweep through Wednesday evening, dropping temperatures sharply. By Thursday, expect highs in the mid-70s from Washington to Portland, Maine, with low humidity and clear skies. The pleasant stretch should hold through the weekend, with overnight lows in the upper 50s to low 60s. If you have outdoor plans, Thursday through Saturday is your window. Enjoy it; models suggest the heat rebuilds early next week.

SOUTH: No relief in sight. The heat dome anchored over the Gulf states shows no sign of budging. Daily highs of 98–104°F are expected from Dallas to Atlanta through the entire seven-day period, with heat-index values — what it actually feels like when you factor in humidity — reaching 110–115°F during peak afternoon hours. The National Weather Service has extended excessive-heat warnings through at least Friday for most of Texas, Louisiana, Mississippi, Alabama, and Georgia. Limit outdoor exertion to early morning and evening. Stay hydrated. Check on elderly neighbours. This is dangerous heat, and it will not let up this week.

CENTRAL PLAINS: Severe weather is the headline. The collision between the advancing cold front and the warm, moisture-laden air surging north from the Gulf will set up a multi-day severe-weather outbreak across Kansas, Oklahoma, Nebraska, and western Missouri from Wednesday through Friday. The Storm Prediction Center has already flagged Wednesday evening and Thursday afternoon as the periods of highest concern, with the potential for supercell thunderstorms producing large hail, damaging straight-line winds of 70 mph or greater, and isolated tornadoes. Friday brings a secondary round of storms as the front stalls and a low-pressure wave tracks along it. If you are in the threat zone, make sure you have a way to receive warnings — a weather radio, a phone alert, or both — and know where your safe room is before you need it.

PRECIPITATION: Rain chances are minimal across the Northeast after Wednesday's frontal passage — perhaps a stray shower on Sunday as a weak disturbance clips northern New England, but nothing organised. The South will see scattered afternoon thunderstorms daily, as it always does in July, with locally heavy rainfall possible but no widespread flooding expected. The Plains will pick up 1–3 inches of rain from the severe-weather complex, with locally higher amounts where storms train over the same areas — flash flooding is a real possibility in low-lying terrain and urban areas with poor drainage. Keep an eye on creek and river levels Thursday and Friday.

TROPICS: A disorganised cluster of thunderstorms over the central Atlantic, roughly 1,200 miles east of the Lesser Antilles, is being monitored by the National Hurricane Center. As of Sunday evening it has a 30% chance of development over the next seven days. No immediate threat to the U.S. coastline, but interests in the Caribbean and along the Gulf Coast should keep an eye on it. We will update if anything changes.

PLANNING AHEAD: For the Northeast, this is the week to catch up on yard work, outdoor dining, and anything that requires comfortable temperatures — the Thursday-through-Saturday window of highs in the 74–78°F range will feel like a gift after the past two weeks of heat. For the South, this is a week to stay indoors during the afternoon; schedule any necessary outdoor work before 10 a.m. or after 6 p.m. For the Plains, keep plans flexible Wednesday through Friday and have a backup for any outdoor events during the severe-weather window.

We will have forecast updates daily at 6 a.m. and 5 p.m. Eastern. Stay safe out there.
