Anyone who’s accidentally brushed against a searing seat-belt buckle this week knows: summer has hit the broiler setting in North Texas, and it’s just going to get worse.

The National Weather Service has issued a heat advisory through Saturday and says the next week will feel as hot as 109 degrees. Some forecasts have triple digit temperatures for the next 15 days.

Is sweater weather around the corner?

Expect a cooldown overnight across North Texas. On Saturday, temperatures could be up to 20 degrees cooler. Temperatures could fall into the 50s in parts of Dallas-Fort Worth during the early morning hours. (Best bet for that is in Denton County and to the counties west and north of Denton, the National Weather Service reports.)
