Warming centers have been opened across metro Atlanta in response to forecast low temperatures falling well below freezing, as a strong arctic air mass is expected to keep temperatures well below normal throughout the weekend.

Some parts of the metro area will see lows in the 20s Friday evening, while some parts of northeast Georgia may see the mercury dip into the teens by Tuesday morning.

Highs will be in the low 50s on Saturday and Sunday with dry conditions. Another shot of Arctic air arrives on Monday and Tuesday. Highs will be in the mid 40s, lows will be in the 20s. On Tuesday and Wednesday mornings, the subway could get into the teens.
