We are tracking a storm system that will move in Saturday. This system has the potential to produce pockets of heavy rain, thunder, lightning, gusty wind and even the threat for a brief spin up tornado. We don't anticipate a wide spread threat for severe storms, but I want everyone to be aware that a few of these storms could turn severe.
Storm risk: The main storm risk will be in Alabama and Mississippi. That's where there is a "slight" risk for severe storms. That's level 2 out of 5. There will be a better chance for severe storms there.
As this system approaches Georgia, it becomes a "marginal" risk. That's level 1 out of 5. There will be a chance of only isolated storms in the green shaded region.
Here's the timeline: Showers roll into the area Saturday morning These will be just general light scattered showers. Then, in the late afternoon hours, we will begin to see the line of thunderstorms moving into NW Georgia between 4-6pm, through metro Atlanta from 6-9pm, and east of Atlanta after 9pm. We will keep monitoring the timeline and impacts.
The rain is caused by a cold front which will be followed by very cold air, possibly the coldest since January 2018.
As the temperatures fall overnight Saturday into early Sunday and the moisture moves out, it is possible for some snow flurries over parts of north Georgia Sunday morning. We don't expect any problems with this. IF there are any accumulations, they would be very light over far north Georgia.
We'll likely hit our high temperature very early Sunday as temperatures are expected to fall through the day.
That gives way to a windy and cold Sunday night and Monday morning. Lows during this period look to range from the teens in the North Georgia Mountains to the 20s in Atlanta. But a breezy NW wind will make it feels like the teens to single digits further north.
Highs Monday look to hold in the upper 30s to lower 40s, at least it will be sunny.
Tuesday will be warmer and mainly dry.
Showers, and possibly some thunderstorms, look to move in on Wednesday into Thursday. Highs in the upper 50s to lower 60s
