Thompson, Manitoba woke up to a dramatically different feel Monday as cloudy skies and a cool 9.4 C replaced the mainly sunny 20.6 C that residents enjoyed just a day earlier. The shift marks the arrival of an unsettled weather pattern that Environment Canada expects to deliver cooler temperatures and a series of showers through the middle of the week.
As of 1 p.m. Monday, the temperature at Thompson Airport sat at 9.4 C with a north-northwest wind at 18 km/h and humidity at 69 per cent. That is roughly 8 degrees colder than the high of 20.6 C recorded Sunday afternoon under mainly sunny skies and gusty winds. The federal forecaster’s seven-day outlook shows Monday and Tuesday struggling to reach a high of just 12 C, well below the normal June daytime mark of 20 C for this northern Manitoba hub.
Showers remain the main story heading into mid-week. Environment Canada gives a 60 per cent chance of showers through Monday afternoon and again on Tuesday, when skies are expected to stay mainly cloudy. Drier conditions are likely Wednesday and Thursday before rain probabilities pick up again Friday and into the weekend. Temperatures will gradually recover, with highs forecast to climb toward 17 C to 19 C by Sunday, June 21.
Such swings are typical of early summer in Thompson, where a subarctic climate means warm and cool air masses can collide quickly. June averages about eight rainy days and between 76 and 93 millimetres of rain for the month, making this week’s damp pattern right in line with what locals have come to expect. The city, located roughly 761 kilometres north of Winnipeg, serves as the largest community and service hub for Northern Manitoba’s 13,035 residents.
Forecasters from AccuWeather, The Weather Network, and other services align closely with Environment Canada’s outlook. All agree the coolest days have already settled in and that the region will see a gradual warm-up alongside intermittent wet weather heading into the weekend.
