DALLAS-FORT WORTH — Relief from a relentless stretch of heat is finally in sight for North Texas, with cooler air and rain chances arriving midweek next week. A weak cool front and a decent upper-level disturbance are expected to bring 50 percent rain chances on Tuesday and Wednesday, with highs dropping into the 80s by Wednesday. The change comes at the end of what will easily be the hottest September on record for the Dallas-Fort Worth area.
Dallas-Fort Worth Heads for the Hottest September on Record
This September has been unlike any before it in North Texas, as the area has never had a September without a high in the 80s until now. Day after day of hot readings have kept temperatures well above normal throughout the month.
That persistent heat has locked in this month as easily the hottest September on record. The long-running summer pattern has refused to let go, stretching typical summer conditions well past the point when cooler days usually begin showing up.
High Pressure Shifts Into Mexico as a Weak Cool Front Approaches
The pattern responsible for the heat is finally expected to break down next week as the ridge of high pressure moves south into Mexico. That shift opens the door for weather systems to move into Texas after weeks of being blocked.
A decent disturbance paired with a weak cool front is forecast to reach North Texas by midweek. By that time, average highs at DFW sit near 85 degrees, meaning the incoming cooler air will finally bring temperatures back closer to seasonal norms…
