Workweek Outlook: Heat wave history repeats: What 1946 can tell us about this fall

This week's record-breaking heat continues as temperatures climb into the upper twenties each day. A look back at the record books shows that the last time we had this many consecutive days in the upper 20s was 1946. So, I looked into the weather vault to see if it would reveal any secrets about what we might see ahead this Fall.

In September 1946, the heat wave didn't fall back to seasonal temperatures until the 24th, and that was the first morning that year that a frost occurred. Another frost occurred a few days later, before the end of that month. It's interesting to note that October 1946 had another heat wave with record-breaking heat before cooler temperatures finally returned for November and December.  Some long-range weather outlooks suggest the same for Ontario this year - it'll be interesting to see it all play out.

A few clouds Monday morning will give way to sunny skies and afternoon temperatures near 29°C. The record-breaking heat and sunshine continue into Tuesday, with daytime highs of 28°C.

The sunny, dry weather continues until the end of this week, with temperatures consistently reaching 27°C each day.

Some forecast sources suggest that the next chance of rain will be Friday; however, many other weather models suggest it could still be another 7-10 days without rain.
