Arctic outbreak will bring freezing temps

• The state's power grid operator, ERCOT, issued a notice on Monday warning of potential emergency conditions during the cold snap.
• "ERCOT is closely monitoring the weather conditions moving across Texas this and next week," the organization told Axios in a statement. "Grid conditions are expected to be normal, and ERCOT expects to have sufficient supply to meet demand."

What's happening: The frigid air is associated with a polar vortex event that is slated to break off from its Arctic origins and blast southward.

• Lows might be in the mid-20s Monday morning before bouncing up to 40 degrees — and then diving back down to the upper teens overnight and Tuesday morning.
• The rest of this week will remain mostly sunny and windy before temperatures drop.

What they're saying: "It's going to be a little breezy with this front," Fogarty says, "with pretty low windchills making it feel like less than 5 degrees in parts of the city."

Between the lines: Forecasters are not anticipating precipitation with this storm, which is good news given Texas' recent experience with ice storms.

• The 2021 winter storm left millions of households and businesses without electricity and killed 246 people.
• Plus, last year's ice storm saw frozen, falling tree limbs leading to widespread power outages throughout Austin — and, ultimately, a massive shakeup in City Hall leadership.

Of note: Staying ahead of the storm, Mayor Kirk Watson and other Austin officials are warning residents to be prepared.

• The city opened cold weather shelters last night, which are activated when temperatures are expected to reach 32 degrees or colder overnight.
