Americans in multiple northern states may have a chance to see the northern lights this week.
According to a forecast from the National Oceanic and Atmospheric Administration's Space Weather Prediction Center (SWPC), the aurora borealis could be visible in as many as 14 states over Tuesday and Wednesday night.
Why It Matters
While NOAA's forecast may not guarantee a sighting, it offers a somewhat rare chance for residents of states ranging from Washington to Maine to witness the celestial phenomenon.
What To Know
According to the SWPC's viewline forecast, the aurora borealis may be visible over parts of Washington, Idaho, Montana, Wyoming, South Dakota, Iowa, Wisconsin, Michigan, New York, New Hampshire, Vermont, and Maine on Tuesday night.
On Wednesday, the SWPC forecasts the northern lights could be seen over parts of Alaska, Washington, Idaho, Montana, Wyoming, South Dakota, Minnesota, Wisconsin, Michigan, Maine, and along New York's northern border with Canada.
The SWPC explains that the northern lights occur when electrons collide with the upper reaches of Earth's atmosphere. These electrons get a boost of energy in an area of Earth's magnetic field on the night side of the planet.
Once energized, they then traverse along the magnetic field toward the polar regions. When they hit gases like oxygen and nitrogen high in the sky, they transfer their energy to those gases, which "excites" them. As the gases calm back down, they release that energy as glowing light.
During "large" events, the aurora may be visible as far south as parts of the United States, Europe, and Asia. In "very large" events, it can be seen even further away from the polar regions.
In addition to clear skies, visibility can depend on factors such as low light pollution and the intensity of the aurora at any given time. Even in areas within the forecast's visibility band, cloud cover or city lights may prevent a sighting.

What People Are Saying
Space Weather Prediction Center operations chief Mike Bettwy previously told Newsweek: "General tips include viewing late at night, away from city lights, and taking pictures with your iPhone or other technology since the aurora may be visible on those devices even though the human eye may not always detect it."
The Space Weather Prediction Center says: "The aurora is not visible during daylight hours. The aurora does not need to be directly overhead but can be observed from as much as 1000 km away when the aurora is bright and if conditions are right."
What Happens Next
The SWPC issues frequent forecast updates. Anyone hoping to catch a glimpse of the aurora borealis should consult the latest outlook and head to dark, clear spots with a good view of the northern horizon.

Michigan among states that could glimpse northern lights. See map
Much of Michigan could see the northern lights on July 26, according to NOAA's Space Weather Prediction Center (SWPC) forecast. The northern lights, also known as the aurora borealis, may be visible in as many as 14 northern states tonight, according to NOAA's SWPC dashboard. According to NOAA, "view lines" Michiganders as far south as Grand Rapids, Lansing and Port Huron may be able to catch a glimpse of the shimmering lights in the night sky to the north. The lights could be overhead for people in parts of the Upper Peninsula. NOAA says a G1 geomagnetic storm, a worldwide disturbance of the Earth's magnetic field, is expected to produce a Kp rating of 5. Kp is an index used to indicate the severity of the global magnetic disturbances in near-Earth space, NOAA said. Kp ratings increase from zero to 9+. NOAA is predicting moderate and minor geomagnetic storm impacts. Some high latitude electrical systems could suffer damage, radios could be affected among other issues. When could the northern lights be visible? The northern lights could be visible in Michigan Saturday, July 26, according to SPWC. What are the northern lights? The northern lights, or aurora borealis, are waves of light created when the solar wind strikes the atmosphere, creating a display of moving lights in the night sky. Which states could see the northern lights? The NOAA says the red "view line" marks the southernmost extent where aurora might be seen on the northern horizon. While more than a dozen states have a chance to see the northern lights on July 26, Alaska has the greatest chance to see the spectacle, followed by parts of the following states: Idaho Michigan Washington Montana Wyoming North Dakota South Dakota Minnesota Wisconsin New York Vermont New Hampshire Maine Why do the northern lights have different colors? The color of the aurora depends on which gas is being excited by the electrons and on how much energy is being exchanged, NASA said. Oxygen emits either a greenish-yellow light (the most familiar color of the aurora) or a red light; nitrogen generally gives off a blue light. The oxygen and nitrogen molecules also emit ultraviolet light, which can only be detected by special cameras on satellites.

Millions Across 11 States Told To Stay out of Sun, Limit Activity
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Millions of Americans across almost a dozen states were instructed to stay out of the sun and limit outdoor activities, as the National Weather Service (NWS) issued a sweeping series of extreme heat warnings and advisories amid dangerous temperatures. Dozens of cities in 11 states throughout the South, Midwest, and Southwest face dangerous heat, prompting health alerts and safety guidance for vulnerable communities. Why It Matters The Centers for Disease Control and Prevention (CDC) warned that extreme heat is the deadliest weather phenomenon in the United States, causing more than 700 deaths annually. Vulnerable populations, including children, seniors, and people with chronic health conditions, face elevated risks of heat-related illness such as heat stroke and exhaustion. Rising temperatures also amplify ground-level ozone pollution, compounding risks for those with asthma or heart complaints. People drink water as they walk along the National Mall near the Washington Monument in Washington, D.C., on July 25, 2025, as a heat dome sits over the region leading to extremely high temperatures.

Getty Images What To Know According to the NWS Extreme Heat Warning map and recent reports, extreme heat warnings are in effect for 11 states—affecting hundreds of cities and millions of residents. The hardest-hit areas were parts of Iowa, southwest Minnesota, northeast Nebraska, and most of South Dakota. These regions are forecast to experience heat index values at or above 110 degrees Fahrenheit. In their statements on the heat warning, the NWS advised: "Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors." Officials reiterated not to leave children or pets unattended in vehicles, as car interiors can reach deadly temperatures within minutes. "For the Heat Advisory, warm and muggy conditions will continue early this morning. For the Extreme Heat Warning, dangerously hot conditions with heat index values 111 to 115 expected," the NWS said. Simultaneously, less severe heat advisories stretched across the South, Midwest, and Northeast—including Georgia and southeast South Carolina, where forecast heat index values routinely top 100 F. Cities across affected regions have opened cooling centers for residents without air conditioning, with officials encouraging people to stay indoors and avoid outdoor activities during peak heat hours. The exact temperature thresholds that trigger heat advisories vary geographically, but all current warnings indicate conditions that push the human body beyond normal heat tolerance limits. What People Are Saying The NWS in Phoenix, Arizona, said in a statement on Sunday: "Drink plenty of fluids, stay in an air-conditioned room, stay in the shade, and check up on relatives and neighbors. "Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes. "Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke." What Happens Next At the time of publication, the latest extreme heat warnings remain in effect until at least 9 p.m. CDT Thursday, with the NWS advising residents to stay informed as conditions may shift.
