Smoke, heat and risk of thunderstorm in the Maritimes
CTV Atlantic meteorologist Kalin Mitchell has details on Thursday's heat and a risk of thunderstorms for parts of New Brunswick.
CTV Atlantic meteorologist Kalin Mitchell has details on Thursday's heat and a risk of thunderstorms for parts of New Brunswick.
As sunny and hotter June weather extends through the middle of the week, a risk of thunderstorms develops for parts of New Brunswick Thursday.
Haze in the sky
There is a very thin haze of wildfire smoke present high aloft of the Maritimes on Wednesday.
It is high enough to not impact air quality. There is a chance that during the night some of the smoke may start to mix down closer to the surface, especially in northern New Brunswick. I would still rate the risk of any impact to air quality as low. The presence of the smoke can produce sunsets with more orange and red hues.
The thin haze of smoke may continue to be present over parts of the region on Thursday.

Heating up
Temperatures stepped up across the Maritimes on Wednesday as a high-pressure ridge moved more directly into place.
High temperatures on Wednesday are expected to reach the mid-to-high 20s across much of the region with some communities in northern New Brunswick approaching the low 30s. Temperatures are more moderate on the Bay of Fundy coastline of New Brunswick and direct Atlantic coastal areas of Nova Scotia. Those locations are more exposed to the southwest wind coming in off cooler ocean waters.
It will be a warmer-to-milder Wednesday night with most low temperatures not expected to fall below the high-single digits and low-teens.
Similar hot weather is expected on Thursday. Spotty showers on Friday may cool parts of Nova Scotia and Prince Edward Island. A more widespread cooling of temperatures is expected on the weekend for the Maritimes.
Thursday
Hotter early June weather again on Thursday. A risk of thunderstorms in New Brunswick.
Risk of Thursday thunderstorms
The building heat and humidity will increase the energy available for thunderstorms to develop across western and northern areas of New Brunswick tomorrow.
A weak cold front moving in from the west will act as a trigger for the thunderstorms. The period of greatest risk extends from early afternoon through mid-evening, the hours of about 2 p.m. through 9 p.m. Any ongoing thunderstorms should be in the process of weaking 9 p.m. to midnight.
Front
The building heat and humidity combined with a weather front from the west triggering thunderstorm development in New Brunswick tomorrow.
Aside from lightning, which is dangerous anytime, hazards with the thunderstorms could include locally strong wind gusts, brief downpours, and small hail. When thunder roars head indoors, wait 30 minutes after the last rumble of thunder to head back outside. Environment Canada host a resource to keep track of lightning danger here.
The presence of wildfire smoke can sometimes inhibit the development of thunderstorms as, if it is thick enough, it can reduce daytime heating from the sun. Any remaining smoke above the Maritimes on Thursday is expected to be faint enough to not factor into the risk of thunderstorms.
Thursday storm
The risk of thunderstorms Thursday will be in western and northern areas of New Brunswick.

'It's unpredictable': Shifting winds bring fresh wildfire threat to La Ronge, Sask.
Social Sharing Strong winds pushing a wildfire toward the industrial park and Eagle Point areas, just northeast of the Town of La Ronge, triggered an alert for the region on Friday morning. The community is already subject to an evacuation order, but any people that haven't left those particular areas were told to get to a safe place. Tammy Cook-Searson, chief of the Lac La Ronge Indian Band, said the situation is serious and unpredictable. "The wind has shifted. It's coming in from the southwest right now and it's pushing the fire northeast," she said. Cook-Searson said the Pisew Fire, which began near Hall Lake, has since grown to threaten several surrounding communities. There's been significant structure losses in both Hall Lake, west of La Ronge, and Sucker River, north of La Ronge, due to the fire. "The fire is less than two kilometers just north of Sucker River and it's heading northeast," she said. "And then there's also the fire that has reached Cambridge, where the bridge has burnt and the structure has been lost there and it's moving northwest." Cook-Searson confirmed that both Highway 2 and Highway 102 are currently closed and impassable due to wildfire activity. Any people still in La Ronge are being directed to the Jonas Roberts Memorial Community Centre, which is serving as the local muster point. "Right now it's unpredictable," Cook-Searson said. "The flames were pretty big this morning just before 5 a.m. right behind the fire base on the Industrial Road in the town of La Ronge." WATCH | Crews focus on defence as several Prairie wildfires merge: Crews focus on defence as several Prairie wildfires merge 17 hours ago Duration 3:09 More than 30,000 people in Manitoba and Saskatchewan have now left their homes as out-of-control wildfires advance on multiple communities. On the border, several fires merged to nearly surround Flin Flon, Man., and Creighton, Sask. Cook-Searson said emergency crews are working hard to hold the line. "We are expecting rain starting at noon today," she added. "So hopefully it materializes and fingers crossed that we do get that rain — much needed rain — because the fires are burning out of control." Residents are urged to stay away from the area and continue following evacuation guidance from local officials and emergency services. Celebrating even through hard times Despite the hardship and danger, some evacuees have found small ways to stay hopeful. Some drivers fleeing La Ronge earlier in the week were forced to wait for hours on the highway due to smoke and fire. That's where Terri Roberts and others met up with a friend — whose granddaughter was having a birthday. They brought the cake along, and sang right there on the roadside. 'She was holding her cake and we all started singing 'Happy Birthday' to her outside of the car," Roberts said. "I've never experienced something like that, but it was pretty emotional." "She was just full of smiles and we could see she was quite appreciative of what we did for her." Roberts says they eventually made it south to safety.

Halifax police warn about ‘dangerous drug' seized during traffic stop
Police in the Halifax area are warning the public about a 'dangerous drug combination' seized during a traffic stop in April. Halifax Regional Police officers pulled over a suspected impaired driver near Sea King Drive and Albro Lake Road around 3:30 a.m. on April 20. Police say they seized and searched the vehicle and found an 'unknown substance' inside. The substance, described as a grainy powder grey/green in colour, was sent to Health Canada for identification. This week, Health Canada confirmed metonitazene – a potent synthetic opioid – was detected in the substance, along with fentanyl, caffeine and dimethyl sulfone. 'This combination of drugs is dangerous and may put users more at risk of an overdose,' said Const. Martin Cromwell in a news release. 'Even handling these substances can be risky without taking proper precautions.' Police are reminding the public that Naloxone can reverse an opioid overdose. Naloxone kits are available free of charge through the Nova Scotia Health's Take Home Naloxone Program. For more Nova Scotia news, visit our dedicated provincial page

First case of dermo disease detected in N.L. oysters
Federal food safety officials say they've confirmed the first case of dermo disease in oysters from Newfoundland and Labrador. It's a disease caused by the parasite Perkinsus marinus, and can cause significant mortality of both cultured and wild oysters, according to the Canadian Food Inspection Agency website. The first case in Canada was found in November in New Brunswick, and it has since been found in oysters from Nova Scotia and Prince Edward Island. The CFIA says the disease has now been detected in oyster samples from Notre Dame Bay, N.L. On May 30 CFIA issued a quarantine order at Notre Dame Bay Mussel Farms Inc. due to dermo's detection. "The company is cooperating and complying with all regulatory orders and is following government-approved policies for reporting," said the notice. The parasite doesn't pose a risk to human health or food safety, but the agency says the illness can cause increased oyster mortality and decreased growth rates as it can spread from oyster to oyster and also through water contaminated with the parasite. The CFIA says it's working with the province and Fisheries and Oceans Canada to increase oyster monitoring, control the movement of oysters in the area and look for the source of the illness.
