(Bloomberg) --
The air quality is in the moderate range across most of the US Northeast and parts of Canada, including New York, Quebec and Ontario this morning, with worse conditions in Alberta and Saskatchewan where more fires are burning.
Smoke from the Canadian fires has drifted across the Atlantic and is now in the skies over western Europe, according to AirNow.gov maps. The plume, however, is well above the ground.
New York can expect scattered showers throughout the day and the US Storm Prediction Center said there is a marginal risk that severe thunderstorms could pop up during the day, accompanied by downpours, winds and hail.
“Compared to previous days there is hardly any smoke across the Northeast,” said Bob Oravec, a senior branch forecaster at the US Weather Prediction Center.
It doesn't mean that will last. An upper level low is forming over the Great Lakes and that “is looking to act as a tap to bring more smoke,” he said. Late spring has been marked by these powerful low pressure systems that have kept conditions cool and helped funnel smoke from Quebec's remote forests across the urban areas of Canada and the US.
“As long as those fires are still burning there are going to be chances for some kind of smoke coming south,” Oravec said.
As of June 11, there were 435 active fires across Canada, according to the Canadian Interagency Forest Fire Centre. So far this year, 2,487 fires have burned about 4.8 million hectares, the agency said.
