Austin weather: Freezing temps here, Winter Weather Advisory updated

The Arctic air has arrived.

Central Texas started Sunday with below-freezing temperatures, with the lowest being Mason at 18 degrees and the highest being La Grange at 31 degrees. Austin began Sunday at 26 degrees.

However, that wind chill drops the temps down significantly, even into the single digits in Burnet and down to 16 degrees in Austin and at Austin-Bergstrom International Airport.

Temperatures in Austin are expected to stay below freezing all day and even through Monday.

A Winter Weather Advisory has been changed to begin at noon Sunday (1/14) and run through noon Monday (1/15). The Advisory has also been expanded to include Edwards and Dimmit counties. NWS says that the changes were due to "isolated reports of frozen precipitation so far across the region."

Freezing rain is expected and could accumulate to a few hundredths up to one-tenth of an inch. 

The main concern remains the possibility of minor ice accumulation on elevated roadways like bridges and overpasses. 

If ice accumulates, the best chance will be Monday morning. Then, drier air filters in, causing the ice to disappear or sublimate (go from a solid to a gas state) Monday afternoon.

The biggest threat of this Arctic air mass is dangerously cold temperatures from Sunday-Wednesday afternoon. Feels-like temperatures will dip into the single digits on Tuesday morning and possibly negative numbers in some spots. 

Please stay indoors as much as possible, and if you do go outside during these dangerous freezing days, limit the duration and dress in layers. 

Also, if you have pets, bring them inside with you. If it is too cold for you, it is too cold for them, and these temperatures will be too cold for everyone. 

Stay safe, and stay tuned in for updates.
