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.

Another surge of arctic air and freezing temperatures will arrive on Monday into Tuesday. The Houston area is projected to see temperatures as low as 26 degrees late Monday and 24 degrees on Tuesday,

Long-range models indicate the chance of another arctic blast early next week, which could bring the coldest air so far this season.

Warming buses will be located at five different locations along the 26-mile route Sunday, offering opportunities for runners to warm up. Free gloves also will be distributed during a pre-race event on Friday and Saturday.

The Houston area is seeing an increasing chance that a mix of wintry precipitation—including snow—is headed in its direction. Space City Weather meteorologist Eric Berger said there is a growing possibility (about a 50-50 chance) of snow or sleet beginning next Monday night and Tuesday.
