The city of Dallas has a humid subtropical climate (Köppen climate classification: Cfa) that is characteristic of the Southern Plains of the United States. Dallas experiences distinct four seasons. July and August are typically the hottest months, with an average low of 76.7 °F (25 °C) and an average high of 96.0 °F (36 °C). January is typically the coldest month, with an average low of 37.3 °F (3 °C) and an average high of 56.8 °F (14 °C). Located at the lower-end of the Tornado Alley, it is often prone to storms.
A couple of times each year, warm and humid air from the south overrides cold, dry air, leading to freezing rain, which often causes major disruptions in the city if the roads and highways become slick. On the other hand, daytime highs above 65 °F (18 °C) are not unusual during the winter season. Extremes in weather are more readily seen in Dallas and Texas as a whole than along the Pacific and Atlantic coasts, due to the state's location in the interior of the United States.
Spring and autumn bring pleasant weather to the area. Vibrant wildflowers (such as the bluebonnet, Indian paintbrush and other flora) bloom in spring and are planted around the highways throughout Texas. Springtime weather can be quite volatile, but temperatures themselves are mild. The weather in Dallas is also generally pleasant between late September and early December, and unlike springtime, major storms rarely form in the area.
In the spring, cool fronts moving south from Canada collide with warm, humid air streaming in from the Gulf Coast. When these fronts meet over north central Texas, severe thunderstorms are generated with spectacular lightning shows, torrents of rain, hail, and occasionally, tornadoes. Over time, tornadoes have perhaps been the biggest natural threat to the city.
