Daytime highs are expected to drop slightly as the heat wave moves out, but those in the area can expect a daytime high of 28 C by Saturday afternoon. The nighttime will bring cooler temperatures than the city has seen in a while. The mercury could drop to a low of 17 C. By Sunday, those in the Greater Montreal area can prepare for a high of 28 C once again, with similar conditions expected to continue into next week.
