New York City woke up to a sticky start Thursday, with clear skies, muggy air and official readings near 73°F paired with about 90% humidity. A Heat Advisory is in place from noon Thursday, June 11, through 8 p.m. Friday, June 12, with heat‑index values expected to climb into the mid‑90s to around 100°F across many inland and urban neighborhoods. Scattered showers and thunderstorms could pop up after 5 p.m. Thursday, and a better shot at more organized storms arrives Friday evening that could briefly tangle up the ride home.
Heat Advisory And Air Quality
Forecasters are urging New Yorkers to take it easy outdoors during the peak heat, with seniors, infants and people who work outside facing the highest risk. According to NWS Upton, much of the city falls under the advisory, and heat‑index readings may push toward 100°F in neighborhoods away from the immediate coastline. On top of that, the New York State Department of Environmental Conservation has issued an Air Quality Health Advisory for the metro area from 11 a.m. to 11 p.m. Thursday. People with asthma or heart disease are urged to cut back on prolonged outdoor activity and can follow updated guidance on the DEC AQI page.
Storms Tonight And Friday
Showers and a few thunderstorms may start to bubble up after about 5 p.m. Thursday, with the best chance for stronger cells late in the afternoon and into the evening. Widespread severe weather is not expected, but any isolated to scattered storms that do form could bring damaging wind gusts, brief heavy downpours and small hail, along with localized flash flooding where storms repeatedly track over the same areas. West winds are forecast to increase into the teens with higher gusts later in the day, so commuters should be ready for sudden downpours and possible short delays during the evening rush.
What To Do This Week
Plan around the heat and the flip‑of‑a‑switch skies: move strenuous outdoor work into the morning hours, drink plenty of water and keep weather alerts close for fast updates. If you do not have air conditioning, call 311 or use the city’s Cool Options map to track down an open cooling center and check in on vulnerable neighbors. Boaters and beachgoers should keep an eye on a moderate rip‑current risk and follow marine guidance until conditions improve.
