Triple-digit summers made hotter by acres of pavement, sudden winter freezes that catch idle furnaces off guard, and sticky Trinity River humidity that never quite lets coils dry out.

The strongest urban heat retention in the Metroplex, layered over the same 100°F-plus summers, flash freezes, and Gulf humidity the rest of North Texas gets.

Hot open-land summers with little shade over new rooftops, plus sharper, earlier northern cold snaps that push heat pumps through more freeze-thaw cycling.

Open-land heat with almost no shade, wide day-to-night temperature swings away from the city's warmth, and propane-fueled heating that behaves differently than gas in a freeze.

Full open-prairie sun with little windbreak, hot dry summers cracking the clay soil, and the same abrupt winter fronts that sweep down across North Texas.

Hot, sun-exposed southern-prairie summers, agricultural dust in the air, and industrial heat around Midlothian layered on top of standard North Texas extremes.

The widest temperature swings in the region, hot open days and cold clear nights, with rural dust and propane heating in the mix.

Lake-driven humidity along the Granbury shoreline, all-day occupancy that keeps systems running, and the standard North Texas heat and freeze extremes on top.
