Peak of heat wave expected today.. thunderstorms likely Wednesday with cooler and more comfortable conditions by Thursday..
The heat wave which has been affecting southern Manitoba since Saturday is expected to peak today with afternoon temperatures of 35-38C forecast, along with humidex values in the mid 40s. In Winnipeg, highs of 36C are forecast which would be a record for the day (currently 34.4C in 1967), and likely the city's hottest day since Aug 19 2003 when we hit 35.9C. Today should be the hottest day of the heat wave before a cold front pushes through Wednesday bringing some welcome showers and thunderstorms that will likely be accompanied by locally heavy rainfall. Cooler and more comfortable conditions will follow in the wake of the front by Thursday with seasonable temperatures and lower humidity.
