Undated, AL – It will be cold Monday night. Weather forecasters expect some of the lowest temperatures of the winter season as Arctic air continues to push to the Gulf Coast. The National Weather Service reports temperatures may reach 11 degrees in parts of north Alabama. It won't be much better in southern Alabama with temperatures expected to drop as low as the low 20s. Weather forecasters are making the usual recommendations, and even the Birmingham Water Works is asking residents to take care. They suggest doing what you can to keep water pipes from freezing overnight. That includes covering exposed pipes, allowing faucets to drip overnight and setting heat thermostats no lower than 55 degrees.
