Temperatures will slowly rise toward climate-normal levels this week. But another strong arctic cold front will blast through on Saturday.

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.

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

Houston weather next week includes chances for freezing rain, sleet and even snow beginning late Monday and lasting through Tuesday. Here's the forecast.
