Houstonians eagerly anticipating an end to the relentless summer heat may find a sliver of relief during the Labor Day weekend. A weather front is expected to pass through the region, bringing with it modestly cooler and drier air. While not a dramatic shift, this front could lower nighttime temperatures into the mid-70s, and in some areas, even the upper 60s, offering a welcome respite from the sweltering conditions that have persisted for months.
