What's the earliest and the latest it has ever hit 100 degrees in SLC?? I see by the almanac that it was 100 degrees on this date in 1979. Can we breathe a sigh of relief and be confident we won't see 100 degrees again this year?? While we're at it..... What's the earliest and the latest it has ever SNOWED here in SLC??

It appears we are in the clear at least for the next couple of weeks (mid Sept) as far as the 100 degree heat goes. We had 9 days of 100 degree temperatures this summer in Salt Lake.

The earliest date to hit 100 in Salt Lake was June 7, of 1985. The latest date of 100 degrees was September 8, 1979. It's unlikely we'd see 100 degrees again this fall in Salt Lake, however September does usually have 4 days with temperatures at 90 or above.

The earliest date of measureable snow would be September 17th of 1965 where 2.2 inches of snow was measured. Measureable snow is snow of .1 inches or greater. Also on the 18th was the coldest day in September with a low of 27 degrees. There probably have been several days of snow of .1 inches in September though. The latest date of measureable snow was on May 18th 1977 with .5 inches of snow.
