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.

Scattered mainly light rain showers Wednesday with the best chance south of I-10 near the coast. Thursday will be partly sunny and mainly dry with a 10% rain chance. For next week, long-range models indicate the chance of another arctic blast early next week which could bring the coldest air so far this season!

New week in Houston is going to be very cold and windy with a high chance for either sleet, ice or areas of snow.

Freezing rain, sleet and even snow are all possible next week, but the extent and impact of ice is still uncertain due to extreme disagreement among models. Here's what we know.
