Frigid temperatures are expected to descend on Houston during this weekend, according to the National Weather Service

Freezing temperatures are exspected during Chevron Houston Marathon. Wind chills could make it feel like 19 degrees on early Sunday morning, just before thousands of people line up to start the Chevron Houston Marathon, meteorologists said.

Meteorologists said that race day will be partly cloudy and freezing, with wind chills in the morning. Wind speeds will be between 15 to 25 mph.

Sub-20 temperatures are anticipated around 6 a.m. All participants will officially be on course at 7:01 a.m.

The cold weather is expected to remain under 25 degrees for hours, meteorologists said. A hard freeze is possible.

The weather is typically warmer on race day, with previous temperatures averaging 54 degrees, according to the marathon. Runners experienced near-freezing conditions last year, although that wasn't nearly as cold as is expected this weekend. 

27,000 people have signed up for the marathon and Aramco Houston Half Marathon on Sunday.
