Every May it seems we get the over-the-top heat. And it happens fast... like as soon as any semblance of cold vacates Quebec and Ontario, it’s almost instantly in the 80s. Could be snowing one week, then bam the gates of Hades open up and heat goes from Midwest up into N. Quebec. Last year was the big deal where it snowed May 11, then was setting all-time ASOS records in mid-90s a week later it seemed. Even summits MWN and Mansfield were setting all-time high temps after a frigid first two weeks of May.
Today... already 80F at spots like BML, MVL, BTV while BDL, ORH, CON are upper 60s.
