After a cool start to May, many have been left wondering… where is the classic May summer warmth that we are used to seeing? It certainly has been absent thus far. Average temperatures in the Greater Toronto Area are hovering about 5C BELOW the monthly norms for this time of year. It will take quite a bit of warmth to erase this deficit.
Finally however the ensemble and operational models are aligning showing widespread warmth to invade beginning next week. Here’s how its going to look:
MONDAY May 15th: Temps will rise into the high teens for most of Southern Ontario which is seasonal for this time of year. A few reports of 20C can’t be ruled out in the usual warm spots.
TUESDAY May 16th: Seasonal temps will remain across Southern Ontario with highs again reaching the upper teens, and 20C in the classic warm spots including SW ON. This will be the warmest weather felt in many regions since April.
WEDNESDAY May 17th: Finally the warm spreads NE and encompasses all of South (and East). Widespread 20-25C weather across all of Southern and Eastern Ontario with plenty of sunshine.
THURSDAY May 18th: Widespread 20-25C temps remain, a few spots even hitting 26-27C is possible. It will feel like summer.
FRIDAY MAY 19th: Widespread 20-25C temps remain, similar to Thursday.
At this point its looking like next weekend (May 20-21st) could have the core of the heat with highs in the 25-30C range across Southern Ontario. Some humidity could work its way in pushing RealFeel temps into the low to mid 30’s.
