After one day of milder temperatures on Friday, bitter cold has returned to Billings and the region through the early part of this coming week, the National Weather Service says.
The NWS issued a hazardous weather outlook for portions of central Montana, south central Montana and north central Wyoming starting this morning. Temperatures will be in the single digits and lower teens for highs over the next few days.
In addition to posing a threat for young livestock, the prolonged cold temperatures are increasing the amount of ice on area rivers, the NWS said, and increasing the risk for ice jam flooding.
