DOWNTOWN — The city's hot weather broke another record on Monday, marking the sixth record-breaking day in a row. 

In all of Chicago's recorded history, this is the latest there has been six days of 90-degree weather, according to the National Weather Service. In fact, this could end up being one of the city's warmest Septembers on record.

The fall heat wave started Wednesday, when the city hit a record-breaking 92 degrees. Records for high temperatures have been broken every day since then, and Saturday even tied for being the warmest day of the year when it hit 95 degrees.

The streak continued Monday, when Chicago hit 91 degrees.

The city is "well above" the normal temperature of 64.6 degrees this September, said Ricky Castro, a National Weather Service meteorologist. The normal average temperature for the month was about 3.8 degrees warmer than usual going into Monday morning, and that could rise by the end of the month since Monday and Tuesday will be in the 90s, too.

That means Chicago's just 1.6 degrees cooler than the warmest September on record, when Castro said the month averaged 71.2 degrees in 1931. If temperatures don't fall too much after Tuesday, it could be one of the 10 hottest Septembers in the city's history.

The month isn't just unusually warm: It's also among the driest on record, Castro said: It's on pace to be the fourth-driest September in city history. Just .32 inches of rain have fallen so far.

The heat wave is expected to end Tuesday night, with the city seeing temperatures in the low 70s by Wednesday.
