Freeze warning issued for Atlanta, cold day ahead

Posted: Updated:

It will be another chilly day! We'll see sunny skies today as highs reach the mid 50s. Tonight will not be as cold, as lows only drop down to the lower 40s. Tomorrow we'll see increasing clouds and a slight chance of rain. The chance of rain will continue through Monday.

Here are the latest updates on the arctic blast!

Wednesday evening update

Athens breaks record low that stood for over 100 years!

The temperature dropped to 23 degrees in Athens Wednesday at 5:48 a.m.  This broke a new record which was previously 24 degrees from 1911.  That was over 100 years ago!

WeatherBug shows lows in the teens!

The official low in Atlanta was 28 degrees (taken at Hartsfield-Jackson airport), but our exclusive WeatherBug network is showing even colder lows from Wednesday morning.

The advantage of our Weather Bug network is that we place the thermometers at schools, fire stations and other buildings in the actual city where you're more likely to be!

Atlanta sees first freeze of the season

The temperature in Atlanta dropped to freezing at 12:52 a.m. Wednesday for the first time since March 28.  We eventually dropped to a low of 28 degrees at 7:45 a.m.

This was the first freeze of the season in Atlanta, which was right on schedule.  We typically drop to freezing for the first time each year on Nov. 13.

Another Freeze Warning Thursday morning

Another freeze warning has been issued for all of Metro Atlanta.  It'll be just as cold Thursday morning as it was Wednesday morning. 

The good news is that the wind won't be as strong taking a little bite out of the air.

Tuesday evening update

When does it freeze in Atlanta?

Do you think this cold snap is earlier than normal?  Interestingly, Atlanta will hit freezing on the exact date we typically see freezing temps each year!

Click here for a special post I wrote on "first freezes" in Atlanta.

8 PM Temps - Metro Atlanta in the 30s!

Temperatures were already in the 30s across much of Metro Atlanta as of 8 p.m. Tuesday.  Canton was near freezing!

Cold weather tips

The first freeze is the worst!  Here are a few basic tips to prepare you for the cold:

- Cover your plants and flowers

- Wrap outdoors pipes!

- Bring pets indoors

- Don't forget to turn off the sprinkler system!

5 PM Temperatures

The cold air is moving in!  As of 5 p.m. it's near 70 degrees in Eatonton, but down to 37 degrees in Ellijay!

New alerts

The National Weather Service has issued two alerts for Metro Atlanta, as expected. 

A Freeze Warning is in effect until 10 a.m. Wednesday morning for temperatures that will drop below freezing.  Another freeze warning is also in effect for Thursday morning.

A Wind Advisory is also in effect for Metro Atlanta until 1 a.m. for gusty winds.


Monday night update

The latest models, including Futurecast, are even drier for North Georgia with this system.  As a result, there should be no precipitation in Metro Atlanta at all, but it will be very cold!

As mentioned below, we'll see freezing temperatures Wednesday morning for the first time in over 7 months.

In addition, you can expect gusty winds Tuesday afternoon and Tuesday night.

A Freeze Watch has been issued for Metro Atlanta for Tuesday night and Wednesday morning.  This will likely be upgraded to a Freeze Warning which basically means to expect freezing temperatures.

I've included images of lows for Wednesday morning along with the Freeze Watch below!


Monday morning update

Just looked at the morning model runs which continue to show very cold air moving into Atlanta after Tuesday, but also keeps Atlanta drier than the weekend models.

Monday morning's models keep the slight chance of flurries in the northeast Georgia mountains. 


Sunday afternoon update

Snow?

I'll start with the chance of snow first (since that's what you want to read about).  Arctic air will be moving into Atlanta Tuesday.  Typically this very cold air is accompanied by very dry air, but in this case the models continue to show a band of moisture moving in after the cold front.

This could produce a brief period of rain and snow showers as far south of Atlanta Tuesday night.  The best chance of this happening will be after 10 p.m. Tuesday, and if any flurries fell it would be over by Wednesday morning with no accumulations in Metro Atlanta.

There is a slight chance that colder temperatures in the northeast Georgia mountains could produce a trace of snow for Wednesday morning.

Moisture moving in after the cold air Tuesday night

Slight chance of showers and flurries as far south as Atlanta, but the only chance of any accumulating snow (about a trace) will be in the northeast Georgia mountains.

Cold Air

Due to the arctic air, we'll see the coldest temperatures of the season starting Tuesday night, which will include Atlanta's first freeze.  The last time we saw freezing temperatures in Atlanta was over 7 months ago on March 27.

 


Thursday's original post

Forecast models are showing the coldest air of the season possibly moving into north Georgia by the middle of next week.

A cold front will move through Tuesday night into Wednesday morning and likely produce freezing temperatures across much of North Georgia by Thursday morning.

Snow?

One of the more reliable medium-range models (the European) is brining the rain in after the cold air which would mean the chance of snow, particularly in the north Georgia mountains Wednesday.

The other model I'm looking at (the American GFS) shows a slight chance of quick rain Tuesday night with the cold air moving in afterwards on Wednesday.

At this point, I'm inclined to believe the American GFS model, because its forecast for next week is showing exactly what has been happening so far this season -- we've had cold and dry move in immediately after our cold fronts this fall.

Having said that, the European has historically been better at forecasting winter weather.

Stay tuned! I'll keep updating this blog with newer developments.
