While some may delight in the chance for snow, Dunwoody residents will face the dangers of frostbite and hypothermia if they don't take precautions on Monday and Tuesday.
The area will be under a wind chill advisory from 11 a.m. Monday to 1 p.m. Tuesday that's been issued by the National Weather Service in Peachtree City. Wind chill readings will be as low as 10 degrees below zero.
Whenever you head outside you will feel the affects of northwest winds of 10 to 20 mph, with gusts up to 35 mph.
A wind chill advisory means that very cold air and strong winds will combine to generate low wind chills. This will result in frostbite and lead to hypothermia if precautions are not taken. The National Weather Service advises that if you must go outside, make sure you wear a hat and gloves with the rest of your cold weather gear.
The Weather Channel forecasts a 90 percent chance of snow tonight. Light rain will develop around late afternoon. It will remain cloudy with temperatures steady near the mid 40s. Winds are south-southeast at 5 to 10 mph. A 20 percent chance of rain is forecast.
A steady rain this evening tapering to showers and becoming mixed with snow overnight. The low will be 24. South winds will shift to west-northwest and increase to 15-25 mph. The chance of snow is 90 percent, but don't expect too much. Snow accumulations will be less than one inch.
More worrisome will be the sleet and freezing rain that will come before and even during the snowfall. Travel will be dangerous with icy roads likely on Monday morning.
And it won't get warm enough to be sure any slick spots are gone for the evening commute. The warmest it will be on Monday is 24 degrees, with a low around 4 Monday night. It will be very windy with some morning flurries and mostly sunny skies in the afternoon.
We won't get any break from the cold on Tuesday, with the high only reaching 22 and a low Tuesday night of 13. The wind will be mostly out of the northwest, but will drop to 13 mph during the day and down to 3 mph at night. That will ease the wind chill.
Starting on Wednesday it will begin to warm up, with the high near 41. By the weekend the highs will be in the 50s and the lows above freezing.
