North Texas braces for hottest days since August, cooler air arrives Monday

North Texas is experiencing unusually high temperatures for September, with some areas expected to reach triple digits. This weather pattern is reminiscent of August, which is atypical for this time of year. Last September, the region recorded eight days with temperatures at or above 100°F, marking a significant heat wave. The current heat is attributed to a dome of high pressure that is expected to dominate the area, making Friday the hottest day of the month. As the high-pressure system shifts eastward on Saturday, a slight cooling trend is anticipated, along with increased cloud cover. This change in weather is expected to provide some relief from the extreme heat. Long-range forecast models indicate that a cold front may move through North Texas late Sunday or Monday, which could bring rain and further lower temperatures. The National Weather Service has specific criteria for issuing heat advisories, which include sustained high temperatures over consecutive days. While the 'feels-like' temperature may exceed 105°F, the region has yet to meet the advisory criteria. The upcoming weather changes are significant as they signal a transition towards more typical fall temperatures, coinciding with the official start of the season. Looking ahead, the 10-day forecast suggests a return to more seasonal weather patterns, with the potential for rain and cooler temperatures. However, current predictions indicate that rain chances remain low until there is more consensus in the long-range models. This evolving weather situation highlights the unpredictability of seasonal transitions in North Texas.
