First Alert Weather: Expected to be hottest day of year so far First Alert Weather: Expected to be hottest day of year so far First Alert Weather: Expected to be hottest day of year so far New York City faces another air quality alert Thursday, along with more of the surrounding area. The alert will be in effect from 11 a.m. to 11 p.m. for the city, as well as Long Island, the Hudson Valley and Connecticut. Much of the region was also under an air quality alert Wednesday, but Long Island was not included. Now, parts of New Jersey that were included Wednesday have been removed. CBS News New York Expect another day of hazy skies as smoke and haze continue to funnel in from fires burning in Canada's prairie provinces. The smoke and haze, along with rising humidity levels, will contribute to diminished air quality levels today. The good news is that the haze will gradually dissipate over the next few days, leading to improving air quality levels. CBS News New York The hottest day of 2025, so far, is likely to occur today, with highs reaching the upper 80s to low 90s. As the humidity creeps up, a stray shower or storm may develop to the north and west of the city in the afternoon. Air Quality Index (AQI) today CBS News New York An air quality alert is issued when the Air Quality Index exceeds 100. Today, it's expected to be around 108, slightly higher than Wednesday. The AQI measures air pollution and the associated health risks. The system has six ratings: Good (green): 0 to 50 Moderate (yellow): 51 to 100 Unhealthy for sensitive groups (orange): 101 to 150 Unhealthy (red): 151 to 200 Very unhealthy (purple): 201 to 300 Hazardous (marron): 301 and higher Sensitive groups include people with heart or lung disease, older adults, children and pregnant women. What makes the air quality so bad CBS News New York New York City's air quality often suffers in the summer, especially during heat waves, due to higher temperatures and humidity levels. Stagnant air traps pollutants from cars and factories, creating high levels of fine particulates that react to sunlight and lead to respiratory issues. Sometimes, though, air quality alerts have nothing to do with pollution. In June 2023, smoke from that season's Canadian wildfires blew directly into New York City, leading to an extremely hazardous AQI of 484 -- not only the highest ever recorded in the city, but the worst air quality in the entire world on that date. Tracking storms to end the week CBS News New York For tonight, clouds thicken, and it will be warm and muggy, with lows in the mid 60s to low 70s. As for Friday, another warm and humid day is expected, but not as hot as today. Morning sunshine will give way to afternoon showers and thunderstorms. The severe threat is low, though. A chance of storms lingers into Saturday, with even higher levels of humidity. Stick with our First Alert Weather team for the latest forecast, live radar and weather alerts.

Scotland marks hottest day of the year in long dry spell
Scotland has marked its hottest day of the year so far as temperatures in parts of the country rose above in South Ayrshire, and Tyndrum, in Stirlingshire, both recorded temperatures of 25.5C on beat the previous highest temperatures of the year on Monday by just 0.1C during the driest spring on record so far throughout the Scottish Environment Protection Agency (Sepa) said around half of the country was under a water scarcity alert. Forecasters have warned low levels of rain are ahead for large swathes of the country in coming rivers including the Clyde, Dee, Galloway and Nith are are subject to low water alerts. Sepa said the warm dry weather came off the back of a drier than normal winter and autumn last Johnson, Sepa's senior manager in water industry, said river levels were lower at this time in the season than in previous said the current alert meant people should be aware that water flows are beginning to "show some signs of pressure from the dry weather".Those who use water abstracts from rivers and lochs for business reasons should consider this before extracting it, she added. Ms Johnson told BBC Radio's Lunchtime Live: "We can restrict the amount of water that is taken but we would only do that when we've had really sustained dry periods and there are really low flows in the rivers."We've had below average rainfall throughout the winter and last autumn as well, and spring has been fairly dry."So we have come into the summer season with flows than we might expect to see. It has been very warm and dry."She added: "They are lower at this time in the season compared to other years." Will we ever see the rain? So is Scotland now a dry country, albeit in the weather sense?In Leuchars, Fife, it had not rained for 24 days as of Tuesday a whole, the UK is only running at 80mm of precipitation – making it the driest spring on record so Scotland weather presenter Kirsteen MacDonald said parts of the country were going into their fourth straight week without said "scarcely any" rain is forecast for the coming days, but some areas could see heavy showers over the weekend."High pressure will dominate our weather throughout the rest of this week and into the beginning of next week, resulting in settled conditions with lots of sunshine," she said."Temperatures will remain significantly above average for many too."By Sunday, we are likely to have some heavy, thundery showers break out in central and south western areas. "However, this is some way off in terms of forecasting, so the detail is subject to change."
