DOWNTOWN — The city's warm weather has broken at least one record this week — and it could break even more as the heat continues.

Chicago hit a record-breaking 92 degrees Wednesday, and it's expected to hit 92 degrees again on Thursday. If that happens, the city will tie its record for the highest recorded temperature for Sept. 21 — or it could even break the record if temperatures climb higher.

"The very hot-to-warm pattern is going to continue through the early part of next week, and then it looks like it's going to finally turn down after that," said Ricky Castro, a National Weather Service meteorologist.

Temperatures will stick to low 90s and high 80s through the weekend and into early next week, Castro said. The normal temperature for Sept. 21 is 73 degrees.

There will be some clouds through the weekend, Castro said, but no rain is expected, and the days are expected to be "pretty sunny."

"Take advantage, I guess, to go to the beach," Castro said. "Late season trip to the lakefront, you know?"

The downside is the humidity. It will be "fairly uncomfortable" the next few days due to higher humidity, Castro said.

It hasn't been this hot in Chicago on or after Sept. 20 since 1971, when temperatures hit 92 degrees on Oct. 1, according to the National Weather Service.

And there have only been five times in the city's recorded history when there were multiple 90-degree days on or after Sept. 20: in 1895, 1931, 1937, 1953 and once in 1971.
