The September long weekend forecast for Edmonton is pretty bleak
The September long weekend is fast approaching, and if you were hoping to squeeze every last bit of summer out of Edmonton, the forecast isn’t exactly thrilling.
Heading into the final long weekend of what’s been a soggy summer season, the city is looking at a familiar mix of clouds and rain, with temperatures hovering around or below average.
According to Environment and Climate Change Canada (ECCC), Friday, Sept. 4, will reach a high of 19Ā°C with a 30 per cent chance of showers, with rain possible overnight and a low of 10Ā°C.
