Thousands of runners and walkers take to the streets of Houston this Sunday. Temperatures at the starting line will be in the mid-30s but it will feel like the upper-20s with the wind chill. Temperatures will warm to the lower-40s through the morning under sunny skies. It was actually colder last year.

Houston-area officials are urging caution among residents as the second arctic front of 2025 is set to bring a hard freeze and chances of wintery precipitation across the region starting on Jan. 20.
