No hot weather or Fall-like weather to start August
Friday, August 1, 2014, 12:10 PM -
Our weather feels more like summer again just in time for the long weekend. While we do not have any truly hot weather in our forecast, we are finished with the fall-like temperatures for at least the next week.
For Friday afternoon and Saturday we do have the threat for scattered showers and thunderstorms, but most of the time it will not be raining. High temperatures both days will be in the mid 20s with a humidex in the lower 30s.
We cannot rule out an isolated shower or thunderstorm on Sunday, but overall Sunday will be the drier of the two weekend days across Southern Ontario.
The Civic Holiday on Monday will start off with some sunshine, but showers and thunderstorms will develop well north and west of the GTA (including Cottage Country). Late in the day, these storms will approach the GTA, so this could have some impact on late day travel and fireworks.
A slow moving cool front will cross southern Ontario Monday night and the threat for showers and thunderstorms will continue into Tuesday, though we should see clearing during the day, especially to the north of the GTA.
Wednesday and Thursday will be mostly sunny with just isolated showers and thunderstorms and temperatures in the mid 20s – not hot, but considerably warmer than this past week. Our next chance for seeing widespread rain and thunderstorms will come late in the week or next weekend.
Looking ahead to the month of August, it looks like the overall weather pattern will be similar to what we saw during July. The map below is a forecast generated by a model which is in general agreement with where we expect to find warmer than seasonal vs. colder than seasonal temperatures during the month of August.
This forecast is very similar to what we actually saw during July. The map below shows temperatures during July relative to each location’s average temperature. The various shades of blue and green highlight areas that were colder than seasonal during July. This shows that much of Southern Ontario, including the GTA was one to two degrees below seasonal.
While it looks like August temperatures will average out a degree or two below seasonal, summer certainly is not over just yet. We do expect a few periods of warm weather with above average temperatures at times. Also, there are signs that we could see a warmer pattern in Ontario as we head towards September.
