ARCTIC COLD: Another blast of arctic air is descending upon north Georgia with the possibility of record low temperatures and dangerous wind chills. Lows Thursday and Friday will drop into the 5 to 15 degree range. The record low in Atlanta Thursday morning is 13 set in 1958, and the record low Friday is 16 set in 1934. Both have a chance of being broken or tied. Along with the brutal cold winds will be coming out of the northwest at 10-20 mph creating wind chill readings in the -5 to +5 range here in metro Atlanta and in the -15 to -5 range across the higher elevations of the mountains.
In these types of conditions it is important to not leave you skin exposed to the cold, and dress in many warm layers.
WINTRY PRECIP: By Friday the focus will shift to another storm system moving in from the Southwest that could initially spread a wintry mix across north Georgia late Friday and early Saturday. Right now it appears that the initial precipitation will be light. By late Saturday as the heavier moisture builds in temperatures will warm to the point that all precipitation turn to rain. A Winter Weather Watch has been posted for Friday afternoon through Saturday Afternoon.
Another surge of arctic air is on it’s way Wednesday bringing with it some of the coldest, if not the coldest, air of the season. The winds will also increase out of the northwest at 15-25 mph which could cause additional tree, and tree limbs to fall in areas that received the ice.
Temperatures by Thursday morning will hit the single digits and teens with highs only reaching into the 20s. Record low maximums will be broken on Thursday across most of north Georgia. Look for wind chills to drop to near zero and below early Thursday morning as well.
Once we get through the bitter cold on Thursday we then shift our focus to Friday and the possibility of snow by the afternoon and evening. Right now the confidence in this happening is low. It is just showing up on the computer models and the solution will change over the next few days. So just a heads up that snow Friday afternoon is a possibility.
Winter Storm Watch has been issued for all of north Georgia from late Sunday night through Tuesday evening.
A wintry mix of rain, sleet, snow and freezing rain will make travel difficult beginning Monday afternoon.
Accumulating ice on trees and power lines could cause power outages. Some snow will accumulate in areas north of Atlanta with 2 or more inches of snow possible.
Meanwhile a strong cold front will sweep into north Georgia tonight bringing another shot of cold air and windy conditions into early Sunday morning.
WIND & COLD: A cold front will move across north Georgia later tonight bringing very cold temperatures to all of north Georgia.
Lows in the mountains will dip into the teens to near twenty, and that combined with winds out of the NW at 10-20 mph will create wind chill readings near zero. Be sure to wear hats and gloves if headed outdoors. The rest of north Georgia will see overnight lows in the low 20s.
By Sunday afternoon we will see lots of sunshine, but highs will only climb into the mid to upper 30s.
WINTRY MIX: An area of low pressure will develop late Sunday in Texas and push eastward across the Gulf Coast on Monday.
Cold enough air will be in place to support mainly a sleet and rain mix that may transition to snow at times here in the metro Atlanta area north of I-20.
South of I-20 expect just a cold rain. In the north Georgia mountains mainly snow will fall with accumulations likely.
Right now it’s too early to give specific amounts. A slight jog north or south of the storm as it moves across the Gulf Coast could change thing dramatically. Surface temperatures will be cold enough area wide to support some ice accumulation on the roadways overnight Monday into Tuesday.
This could have a major impact on travel. Again this storm is still developing so check back often for updates on the forecast.
Bitter cold air returns from the Arctic later this week, and will eventually cover the entire eastern half of the country. By next week parts of north Georgia may even see a wintry mix of rain, sleet and snow.
BITTER COLD: Very cold air will start to arrive by Thursday with the coldest air getting here by Sunday. Daytime highs can generally be expected to be in the 40s with highs Sunday only in the 30s. Overnight lows will be in the 20s Thursday through next Monday with the coldest morning on Sunday with lows in the teens.
WINTRY MIX: By next Monday moisture will start to move in from the southwest as cold air continues to linger to our north. As the rain moves in late Monday night there is a good possibility that the initial precipitation will begin as a mixture of rain, sleet and snow before finally changing over to all rain. The most likely area would be in northeast Georgia.
By Tuesday temperatures will be above freezing with just rain falling across the Southeast. By late Tuesday and early Wednesday colder air will push in behind the front. If there is enough moisture left over then we could see some snow as the system comes to an end. Certainly something that we will be keeping an eye on quite closely.
Showers move in and then colder air by the end of the week.
RAIN: Showers will develop along a cold front as it moves into north Georgia overnight. Isolated activity will increase slightly toward sunrise just in time for the Monday morning commute. Although the rain will not be heavy it will be enough to wet the roadways and surely slow down traffic. Allow yourself extra time on the morning commute. By the afternoon some clearing will take place and then lots of sunshine will return for the rest of the week.
COLD: Mild temperatures will remain in place through Wednesday with highs in the upper 50s to lower 60s. By late Wednesday a strong, but dry cold front will plow through the Southeast bringing another shot of colder air. Highs will drop into the low to mid 40s both Thursday and Friday with overnight lows dropping into the 20s. Milder air will return for next weekend.
Milder air returns on Wednesday, and then a slight chance of isolated rain and snow showers early Thursday morning.
TIMIMG: Two storm systems will be moving toward the Southeast in the next 24 hours, one bringing mainly high clouds and the other a brief chance at a few rain and snow showers mainly in the northwest corner of the state early Thursday morning. The first system to our southwest will bring abundant rain to the Gulf Coast through Thursday while only spreading high clouds into North Georgia.
The second system is a much drier system pushing south out of Canada, and will arrive Thursday morning as a cold front capable of producing isolated rain and snow showers in northwest Georgia primarily along and north of a line from Rome to Ellijay. Since the system does not have much moisture do not expect to see much of either rain or snow. The most likely timing for that to happen would be between 5am and 8am Thursday morning. The next system on Sunday will be similar in that there wont be much moisture, and it will be much milder so that whatever falls will be just rain late in the day or evening.
IMPACTS: With the first round of showers early Thursday morning we don’t expect any road problems because a) the system is very dry and won’t have much moisture so the precip will be very light and b) the surface temps will be above freezing. The temperature aloft will be below freezing so this should be enough to support some snow, but again it would be brief and light.
WEEKEND WEATHER: The weather will drastically improve this weekend with milder air building in for both Saturday and Sunday. Highs both days should climb to near 60 with overnight lows dropping into the 30s Saturday morning and near 40 by Sunday. The milder weather should hold at least through the first part of next week. Also look for a slight chance of showers late in the day or evening on Sunday.
