The US National Weather Service in Shreveport has released the following statement:

The likelihood of an Arctic air intrusion across much of the CONUS appears to be increasing for early next week. This may result in an extended period of sub-freezing temperatures across our region, in addition to some wintry precipitation starting late Sunday through Monday. 

Temperatures will plummet into the teens in the region. A gusty north wind will accompany this Artic air, possibly resulting in single-digit wind chills. 

An extended period of freezing temperatures will be possible beginning Sunday night through Tuesday. Snow/sleet/ice accumulations cannot be ruled out on Monday into Monday night.

Take precautions and begin preparations now for a hard freeze. Protect pipes, plants, and pets. Check on your elderly neighbors.
