Increasingly warmer daily highs and extended warm seasons are helping a toxic ant spread northward into Washington and the Pacific Northwest, according to recent media reports. Considered “highly invasive,” the Asian needle ant is moving quickly in the U. S., with at least 20 states on alert due to the species’ potentially life-threatening sting. Asian needle ant spread in the U. S. (antmaps.org via OSU)What is the Asian needle ant? Originally from China, Japan, and the Koreas, the ant was first detected in the U. S. in 1932, but it is becoming an increasing problem as warmer temperatures help extend its range. It is small — only about 0.5 cm in length — and can be dark brown or black with orange-brown legs. According to the USDA, you can find the ant under stones, logs, or leaf litter in undisturbed forest. In human-populated zones, they tend to congregate near homes and businesses in sheltered spaces like mulch and landscape timber.

Cool temperatures slowed seeding progress across southeast Saskatchewan during the period from April 28 to May 4, according to the latest crop report from the Saskatchewan Ministry of Agriculture. Five per cent of the crop is now seeded in the southeast, behind the regional five-year average of 10 per cent. Provincially, three per cent of the 2026 crop has been planted.

Friday could bring mixed conditions and showers to the Greater Toronto Area and across southern Ontario. Environment Canada says the morning will bring a mix of sun and clouds with a 30 per cent chance of showers to Toronto, Mississauga, Brampton, Hamilton, Oshawa and the Niagara Falls area.

Published: May 07, 2026 at 3:22p.m. EDTCP24 meteorologist Bill Coulter provides an update on weather conditions in Toronto and parts of the GTA. A frost advisory has been issued for a wide swath of the GTHA ahead of overnight temperatures that could drop to “near or below the freezing mark.”Environment Canada has issued the advisory for most areas surrounding Toronto, including Mississauga, Brampton, Vaughan, Richmond Hill, Markham and Durham Region. For CP24’s full seven-day forecast follow this linkThe advisory is not currently in effect for the City of Toronto itself. “Patchy frost is expected overnight and Friday morning as temperatures drop to near or below the freezing mark,” the advisory states. “Damage to plants, trees, and crops is possible. Cover up plants, especially those in frost-prone areas.”Environment Canada says that the temperature in Toronto is expected to plunge from a high of 12 C on Thursday afternoon to an overnight low of 2 C. The cold, however, will be short-lived. The weather agency is forecasting a daytime high of 15 C on Friday and Saturday. That is still below the typical high seen at this time of year of 17 C but is much closer to seasonal norms.

Researchers from CSU’s Department of Atmospheric Science have conducted multiple projects using weather drones, largely to study cold pools that can destabilize aircraft, form new storms, and kick up dust. Precipitation falling out of a storm cools air as it evaporates or melts. This cooling creates dense air which spreads along the Earth’s surface as a cold pool and feels like cool, windy air underneath storms. Experts Leah Grant, Nick Falk and Russell Perkins – all research scientists – shared 10 details about working with drones in the field: Drone sensors measure wind, temperature, atmospheric pressure, relative humidity/water vapor, and particulate matter. The drones also collect filter samples for analysis in the laboratory. Through field campaigns, researchers have perfected a strategy using at least six drones to take measurements at multiple vertical and horizontal locations. They call the resulting formation the flying curtain.  Researchers use remotes to control drones to measure a stationary position above the ground. These stationary measurements complement ground measurements and moving measurements onboard balloon launches or other manned aviation.

In Harriet Clark’s debut novel, The Hill, a nun explains what it’s like for babies born in prison. “They don’t know that they are in prison,” she says, “but they know when we force them to leave.”The book’s child protagonist is Suzanna, whose mother has been serving a life sentence for as long as she can remember. There is no expectation that Suzanna and her mother will have a relationship outside the prison’s walls. And yet, they do have a sustained relationship within them. The same was true for Harriet and her mother, Judith Clark, who she visited in prison for the better part of almost 40 years. Freedom, Harriet tells me, “never existed on the horizon for me and my mother. I didn’t hope for it. I didn’t treat it as the great dream for her and for me. I knew that as long as I knew my mother, I would just know her in that room.”Judith Clark was sentenced to a minimum of 75 years in 1983 for her involvement in a robbery of a Brink’s armored truck that resulted in the death of three men: a guard and two police officers.

Flooding across the province led to a close call for one man and his passenger, after Highway 335 collapses because of excess water. Hallee Mandryk reports. LAKESIDE, Sask. – Leslie Fetter’s backyard looks more like a body of water after a late snowmelt flooded several parts of central Saskatchewan. Fetter lives in the rural municipality of Lakeside, about 175 kilometres east of Saskatoon. The area is one of more than 20 communities under a local state of emergency due to torrent flooding. “There’s concern. I mean, there’s a lot of water and you can’t control it,” Fetter told CTV News. The water reached its peak over the weekend, submerging dozens of Fetter’s belongings. Vehicles, campers and machinery are all ruined. “It was a mess,” he said. “There were a lot of things floating around. I lost a lot of things.”Saskatchewan extreme weather floods Leslie Fetter stands in his flooded backyard in Lakeside, Sask., on May 6, 2026. (CTV News) Fetter waded through the water to retrieve fuel barrels, tires and fence posts that had floated away in the current. He’s managed to move some of his machinery, including snowmobiles, out of the water.

Thursday could bring showers to the Greater Toronto Area and wind gusts up to 40 km/h in parts of southern Ontario. Environment Canada says the morning will see a mix of sun and cloudy conditions in Toronto, Mississauga, Brampton, Hamilton, Oshawa and the Niagara Falls area.
