The National Weather Service has put out an advisory that temperatures are likely to soar above 100 over the next two to three days in Boise, with overnight lows in the high 60s or low 70s.
The forecast high for Friday and Saturday is 103, while Sunday is expected to reach 101, according to Weather Service meteorologist Aviva Braun.
The record high for July 8 (Saturday) is 103 — set in 1968 — so if we top that, we’ll have a new record.
How’s this early-July heat streak shaping up?
As of Thursday, Boise has had seven days in a row of days over 90 — and all but one of those days were 96 or above.
But we’re a long way from any sort of streak record.
To even break into the Top 10 of consecutive days over 90, we’d have to log more than 22 days in a row (which we did in July of 2006).
Here are the all-time Boise heat streak records:
90 degrees and above streaks
▪ 1. 50 days. Set in 1875, the streak ended Aug. 22.
▪ 2. 44 days. Set in 1994, the streak ended Aug. 20.
▪ 3. 40 days. Set in 1961, the streak ended Aug. 15.
100 degrees and above streaks
▪ 1. 9 days. (three-way tie)
Set in 2015, the streak ended July 4.
Set in 2006, the streak ended July 28.
Set in 2003, the streak ended July 23.
▪ 2. 7 days. (two-way tie)
Set in 1960, the streak ended July 21.
Set in 1931, the streak ended July 26.
▪ 3. 6 days. (two-way tie)
Set in 2012, the streak ended July 12.
Set in 2007, the streak ended July 17.
The hottest month of the year for Boise depends on how far back you go in the data. The hottest month is August if you go all the way back to the late 1800s, but in the past 30 years July has been slightly hotter than August, Braun said.
