We have one final day of extreme heat ahead for most of us in Southern Manitoba on Tuesday as once again, temperatures are expected to climb as high as 37°C.

There is some relief on the way for the region, though, with cool air expected to start pushing southward Tuesday evening and bringing single digit overnight low temperatures to almost the entire province. This might not be quite enough to cancel the Extreme Heat Warning for all of Southeast Manitoba. This area could still see temperatures in the low 30s on Wednesday, particularly around Steinbach and eastward.

This cool down will bring single digit high temperatures back to much of Southern Manitoba later in the week and overnight Friday, temperatures could even dip below the freezing mark. With a low pressure system developing over the region to end the week, we could even see the return of some mixed precipitation with these subzero temperatures. It will definitely be a case of weather whiplash this week!

Monday will mark the second day of our heatwave in Southern Saskatchewan and Manitoba. We will once again have a large area expecting temperatures above 30°C, and above 35°C temperatures are possible in a small pocket of Southern Manitoba that includes Winnipeg. Extreme Heat Warnings remain in place from Environment Canada for parts of Southern Manitoba for daytime highs up to the mid 30s and overnight lows only dropping down to the mid teens.

With extreme heat, it’s important to limit strenuous outdoor activities, if possible, or take multiple breaks and drink water often to protect yourself from heat exhaustion and stroke. Early signs of heat exhaustion include: headache, nausea, dizziness, thirst, dark urine and intense fatigue. In the presence of these symptoms, stop all activities and hydrate. Heat stroke, on the other hand, is much more serious. Heat stroke is most identified by confusion and loss of consciousness so make sure to seek immediate medical condition if someone is showing these symptoms.
