Thunderstorms possible along the foothills on Monday
After an active weekend of weather in and around Calgary, Monday began with calm and clear conditions.
Unfortunately, this period of mild weather is not expected to last for long with most of this week including a risk of rain, potential thunderstorms and a rapid drop in temperatures.
A number of low pressure systems in the upper air patterns within the north Pacific basin will merge together as the week progresses, but rather than track along the typical west to east pathway along the polar jet, this new larger low will remain stuck along the western coast of B.C.

This synoptic setup will enhance instability on the Alberta side of the Rocky Mountains and potentially lead to heavy rain and intense thunderstorm development in the first half of this week.
The first hint of that is on Monday with thunderstorms possible along the foothills, including Calgary. The greatest threats will be medium-sized hail and strong wind.

More persistent rain and cooler temperatures are expected by the weekend, with the high on Saturday closer to the average overnight low.
Calgary could see some form of precipitation most days this week but the heaviest accumulations are likely Friday and Saturday.

Manitoba weather: When will thunderstorms hit Winnipeg?
Colleen Bready has your current conditions and updated weather forecast for June 16, 2025. After relatively stable conditions in southern Manitoba lately, this week is shaping up to bring much more atmospheric instability. It all kicks off Monday with showers and thunderstorms crossing the region. A thunderstorm passed through Brandon late in the morning. Winnipeg is likely in line for showers this afternoon, with the risk of thunderstorms. Environment and Climate Change Canada assesses the city at low risk for poor air quality today until at least Tuesday night.

The precipitation would be welcomed, but lightning strikes would not. Wildfire zones in the north and other northern regions of the province Monday will be sunny or see a mix of sun and cloud with relatively light winds, although they will come from various directions. Tuesday brings a role reversal with sunshine and dry conditions in the south, while the chance of showers shifts to the north. The next meaningful chance of showers or thunderstorms in Winnipeg is on Wednesday. At this point, the potential is much lower, but showers or thunderstorms can't entirely be ruled out Friday or Saturday in the city, with higher odds on Sunday.

LIVE @ 1:30: Sask. to provide wildfire update following week of repatriation, strong fire response
Saskatchewan provides wildfire update after week of repatriation, strong fire response. Watch LIVE here. The Saskatchewan Public Safety Agency (SPSA) will provide an update regarding its wildfire response at 1:30 Monday afternoon, following a positive week that saw many evacuees repatriated and crews gain ground on multiple fires. According to the SPSA's website, 13 wildfires are burning across the province Monday morning. Five are considered not contained. The update can be watched live at the top of this article. The SPSA did not hold any updates over the weekend, however on Friday SPSA president Marlo Pritchard said that all but five evacuation events had ended and more than 10,000 people were being repatriated. The province said it will be working to prioritize getting a $500 payment to all evacuees 18 and older. Pritchard also said that a backlog of people calling the province for help had been addressed, adding that evacuees who call the province for assistance would now be taken care of immediately or within a day. While a provincial fire ban remains in effect, the province also announced that a ban on ATV and UTV vehicles lifted Friday at 5 p.m. The province continues to encourage the public to come forward with information regarding intentionally started wildfires. On Friday the SPSA said it has determined that 30 wildfires have been intentionally set this year. That includes the Ditch02 fire near Weyakwin where RCMP have laid two arson charges. 'We ask for public assistance if they know anything of any of those intentional acts that were conducted. If you know anything, please call Crime Stoppers or your local police jurisdiction,' Pritchard said on Friday. The SPSA also confirmed on Friday that approximately 400 values have been lost to the fires, adding that work is underway to determine more details. Saskatchewan remains under a state of emergency that will stay in effect until June 29, with the province able to extend it at that time if needed. More to come…

Fire evacuees begin returning home to Manitoba First Nation after cool, wet weather
Trees burned by wildfires in northern Manitoba are shown during a helicopter tour in the surrounding area of Flin Flon, Man. on June 12, 2025. THE CANADIAN PRESS/Mike Deal-Pool WINNIPEG — A First Nation in Manitoba is welcoming residents back, almost three weeks after the community of more than 6,000 people was evacuated due to wildfires. The chief of Pimicikamak Cree Nation says a fire in the area is now largely contained and the community has begun a gradual repatriation of evacuees that includes flights today from Winnipeg. Chief David Monias reposted a video on social media showing a steady rain in the region. He says the community's infrastructure is intact and water systems have been tested by health officials. Elsewhere in the province, people in Snow Lake, Sherridon and Herb Lake Landing were allowed to return on the weekend. Officials with the City of Flin Flon say those running critical businesses there have begun to re-enter but the general community will have to wait, as there are no health services and limited fire protection is available. More than 21,000 people in Manitoba had to leave their communities due to this year's early and severe wildfire season.
