Crisis averted, but expect more brrr

Greater Houston was largely spared from icy perils this weekend, though freezing temperatures will again set in Monday and Tuesday.

Why it matters: With the cold sticking around a little while longer, officials are urging people to continue staying home and off the roadways through at least this evening.

Driving the news: Temperatures will rise to the upper 30s in the Houston metro by Monday afternoon and drop to the mid-20s again overnight, National Weather Service forecasters say.

• That means any water still on the roadways could thaw during the day but refreeze overnight, making any driving dangerous.

Zoom in: The city of Houston will continue to operate a dozen 24-hour warming centers for vulnerable residents until further notice.

• 940 people checked into the city's warming centers Saturday night, Mayor John Whitmire said Sunday.

What they're saying: "We were blessed by mother nature and blessed by preparation," Whitmire said.

• "Everyone needs to keep their guard up until at least mid-afternoon (today)," he later said.

What's next: The region will start to thaw tomorrow with temperatures reaching the mid-40s, forecasters say.

• Highs will likely reach the mid-50s by the end of the week before another round of rain and cold temperatures this weekend.
