June temperature outlook
May was yet another cool month for parts of the Prairies and wet month for the West Coast, but summer-like temperatures and storms appeared in the eastern part of the country. For some areas, including Ottawa, Earlton, Montréal and Sherbrooke, there were three consecutive days of temperatures reaching or exceeding 30 °C between May 12 – 14. This has never happened before so early in the season. In Atlantic Canada, the overnight temperatures were below freezing at the beginning of the month, but by May 13, the mid to high 20s were setting daily maximum temperature records.
The most notable storm of the month happened on May 21, when a very strong line of thunderstorms moved through southern Ontario and central Quebec. Peak wind gusts were as high as 132 km/h in Kitchener-Waterloo in Ontario and 144 km/h in Lake Memphremagog in Quebec. Sadly, fatalities and injuries occurred and significant damage to properties and infrastructures was reported.
Here is the forecast for the “temperature anomaly” for the month of June. The temperature anomaly is the “difference from normal temperatures” for the entire month.
The forecasts are categorized as follows:
- blue indicates the probability that temperatures will be below normal;
- grey to purple indicates the probability that temperatures will be near normal; and
- yellow to red indicates the probability that temperatures will be above normal.
This is a prediction of the anomaly of the mean daily temperature at 2 metres (i.e. at standard temperature observation height). It is not a forecast of the maximum nor of the minimum daily temperature.
