The old record of 100 degrees at Hobby was set in 2015.
In a tweet, the National Weather Service also said the temperature at George Bush Intercontinental Airport reached triple digits for the first time all year.
The new record comes amid a heat advisory that is in effect for much of southeast Texas until 7 p.m. Saturday.
If you plan on being outside today, make sure you're aware of the signs of a heat stroke. null
