Baby, it's COLD outside. An arctic front has arrived, putting the brakes on the mild weekend weather. In fact, the colder air may be around for awhile, with several fronts ushering in reinforcing cold air over the coming days and a chance of snow towards the end of the week. Temperatures are forecast to stay below freezing during the day tomorrow (Tuesday) and the next couple of nights, low temperatures will plummet into the teens. Forecast models show a milder pattern for next week, but one thing we know about the weather, it's all subject to change.
