UPDATED: After-School Activities Canceled as Area Awaits Possible Snow

Updated 9:35 a.m. Tuesday: Forecasters at the moment are saying the Tucker area could get a little more than an inch of snow and sleet accumulation over the day and night.

DeKalb County Schools were open Tuesday, but after-school activities were canceled.

Early today, the National Weather Service expanded a winter storm warning to include the entire metro area, along with areas of the state along I-20 on both sides of the city.

The new warning, in effect from 9 a.m. Tuesday through 7 a.m. Wednesday, called for “light to moderate” snow with accumulations of 1 to 2 inches across the metro area.

"Snow is expected to begin as early as mid morning and last into tonight," NWS said in its warning. "Although the snow will end close to midnight Wednesday, snow-covered roads will make for hazardous driving conditions through Wednesday morning."

The NWS has this forecast for today for ZIP Codes 30084 and 30085:

"Snow before 4 p.m., then freezing rain and sleet likely between 4 p.m. and 5 p.m,. then snow, freezing rain, and sleet likely after 5 pm. High near 33. North wind 5 to 10 mph, with gusts as high as 20 mph. Chance of precipitation is 80%. Little or no ice accumulation expected. Total daytime snow and sleet accumulation of around an inch possible."

For Tuesday night:

"Snow likely, mainly before 1 a.m. Cloudy, with a low around 18. Northwest wind around 10 mph, with gusts as high as 20 mph. Chance of precipitation is 70%. New snow accumulation of less than a half inch possible."

"A winter storm warning for moderate snow means severe winter weather conditions are expected or occurring," NWS said. "Significant amounts of snow are forecast that will make travel dangerous. Only travel in an emergency. If you must travel, keep an extra flashlight, food and water in your vehicle in case of an emergency."

The latest winter storm warning extends through Wednesday morning. Wednesday will be mostly sunny, with a high near 36. Northwest winds will be around 10 mph, with gusts as high as 20 mph. The low will be around 16.

"Decisions regarding school for students on Wednesday will be made following updates from the National Weather Service and consultation with the Inclement Weather Team," the school district posted on its website. "Parents, teachers and District employees will be notified of any closings or delays through the District website, social media, local news media, phone trees and emails."
