Region Missing
Does anyone know how to view the forecast for the Lake Superior region of Ontario? When I type in names of towns along the north shore of Superior I get directed to this Southern Ontario page for some reason. I can't seem to find the Northern Ontario regional forecast page.

It does not seem that the May weather is happening as forecast. We live in Barrie and it has been ..thus far..much cooler than predicted. Would be nice to be able to plan outdoor activities and be reasonably confident that if the forecast is shown as warm and dry .. that it will be.
Huh?
It says in the farmer's almanac will be above average for May. In Toronto, it says it's going to be a high of 4 degrees tomorrow (May 8). Isn't it EVER gonna warm up or is this as warm as it's ever gonna get? Does it have anything to do with the coronavirus? Needless to say, 4 degrees and a few other single digit high days in a row does not sound like above normal. I am also concerned if it will be 30 degrees this month. May 11-21 says that it will be turning hot. Maybe they mean hot like 24 or 25 degrees, I mean, I don't consider that hot.
Wow 3 degrees above normal
Wow 3 degrees above normal for May. The weather network says cooler than normal. I think summer will be cooler not hotter. Also, you did great with your winter forecast which was mild.
May weather
May won't be above normal, at least the first week of May will be cooler than normal.

So far spring has not sprung.......too much snow left!
Northern & Southern Ontario
Here in Ontario the north starts as you enter the Nipissing Parry Sound District which is south of Sudbury not north of Thunder Bay. Anything in Southern Ontario is one to two weeks ahead of Northern Ontario (north of Parry Sound) in terms of warming up in the Spring. You really need to get your calendar fixed!
Temp
I have to be honest you guys were way off about this month of March. Most of the month is foretasted to be above normal and you have it several degrees below normal.
