WINNIPEG - Humidex values reaching 38 are expected.
A prolonged period of hot weather will develop over portions of southern and east-central Manitoba today and persist into next week.
Southerly winds will push hot and increasingly humid weather into Manitoba today. Daytime highs will climb into the low thirties with overnight lows rising into the upper teens or low twenties.
These hot temperatures will be joined by humid conditions next week which will increase humidex values into the upper thirties. Notably, the high humidity will likely result in several nights of overnight minimum temperatures in the low twenties. The heat will begin to break through the latter half of next week.
On Sunday, in southwestern Manitoba, a strong cold front will produce a sharp temperature change from highs in the low thirties to its east to highs in the mid-twenties to its west. There is a chance that this front will slide east of Brandon and the Turtle Mountains; if it does those areas may see an early reprieve from the heat.
For most regions in the heat warning, daytime highs may dip a couple degrees on Monday into the upper twenties. Overnight lows will not be impacted by this and daytime highs will climb back into the low thirties for Tuesday and Wednesday.
