There were actually people who said this could rival last January's cold ? This won't even be close. At least 5-7 degrees warmer for both the highs and lows compared to early January last year. This is really just your typical January arctic air. Not even close to record cold. We see this kind of cold almost every January. In a typical winter, our lowest temp is around 12 degrees or so. 

I don't live in Carrollton Georgia but I bet you 100 bucks that you can count the number of 12 degree mornings in the past decade on one hand!

This station has similar readings to Carrollton.  There are six below 12F in January of 2014 alone.

What's up everyone...sorry I haven't been active on this thread over the past day or two, I've got too many irons in the fire right now and don't have much time to do anything without going to something else.

First off...I hope everyone in the Southeast is ready for the next 48-72 hours. This does not look to be as cold as last year but it will be nothing to sneeze at...

I think a problem we run into sometimes is shortly after witnessing a once in a generation type of outbreak like we did last year, we tend to go into this phase of dismissing succeeding events as being nominal. I've noticed that with some of the comments on here at times which is unfortunate...we live in a part of the country that just cannot handle a sustained period of abnormal cold without some inconveniences or disruptions occuring...so I hope everyone takes that into consideration when it all comes down to it.

As far as my specific area, the North Carolina Foothills, I think our numbers will enter the single digits on Thursday morning, may 7 degrees or so...but you won't have to jump very far in elevation to go at or below zero for air temperatures...I think anyone above 2500 ft has a shot. Wind chills will drop to or just below zero for a small period in the foothills with -10 to -20 above 3000 ft...I would be shocked if there are not some school delays in Western North Carolina on Thursday...will those delays cover the entire southeast like it did last January? Maybe...maybe not?

Again, thanks to everyone who have taken part in this thread...please post your Thursday morning low and afternoon high temps in here so we can see how well this event verified...

Under a hard freeze warning and wind chill advisory.

Currently sunny and 59 outside.

It will be interesting if it actually does snow along the FL coast tomorrow. GFS has been on this one for about a week now. 850s are cool enough to support snow and it temps will be in the upper 30s to low 40s. That what the temps are usually when flakes are flying in FL.

Must be gonna get cold in GA... ;)

 

SCHOOL DELAYS: We're starting to get reports of some schools delaying opening tomorrow due to the forecast cold weather: 2wsb.tv/14on9lU

 

Wind chills around 0 to -5 are expected here.  Up in those mountain counties temps should be near 5 with wind chills approaching -10 to -15 I would imagine. 

 

In other news, pretty sure I just hit the high for the day at around 40.  Winds have picked up over the last hour....  Looking for about 12 tonight.

Potential for some light freezing rain tomorrow night???

NWS Jacksonville

A COASTAL TROUGH WILL BEGIN TO DEVELOP

OVER OUR ADJACENT COASTAL WATERS BY LATE IN THE DAY AND THIS COULD

PROVIDE ENOUGH LIFT TO PRODUCE A FEW LIGHT COASTAL

SHOWERS...REMAINING MAINLY OVER THE WATER...WITH ONLY A 20% CHANCE

OF A LIGHT RAIN SHOWER ALONG THE IMMEDIATE COAST OF ST JOHNS AND

FLAGLER COUNTIES THURSDAY AFTERNOON. THERE WILL ALSO BE AN

INCREASE IN STRATOCU CLOUDS ALONG THE COAST LATE IN THE DAY WITH

PORTIONS OF THE COAST BECOMING MOSTLY CLOUDY BY LATE AFTERNOON.

THE TROUGH WILL CONTINUE TO TIGHTEN UP THURSDAY NIGHT AND CLOUDS

WILL CONTINUE TO INCREASE AND COULD SPREAD FARTHER INLAND BY LATE

THURSDAY NIGHT. A SLIGHT CHANCE OF AN ISOLATED LIGHT RAIN SHOWER

WILL EXPAND UP THE COAST TO INCLUDE THE COASTAL COMMUNITIES OF

NASSAU AND DUVAL COUNTIES. TEMPERATURE PROFILES DO NOT SUPPORT ANY

WINTER PRECIPITATION ALONG THE COAST.

IT SHOULD BE NOTED THAT THE STEERING FLOW JUST ABOVE THE SURFACE

WILL QUICKLY VEER TO THE SOUTHWEST AND INCREASE THURSDAY EVENING.

THIS WILL RESULT IN SOME ISENTROPIC LIFT AND MODEL SOUNDINGS

INDICATE A FAIRLY DEEP LAYER OF LOW LEVEL MOISTURE DEVELOPING

BETWEEN 1000 AND 6000 FEET THURSDAY NIGHT. THIS PATTERN COULD

BECOME CONDUCIVE FOR A STRAY LIGHT SHOWER OR TWO ACROSS OUR INLAND

AREAS. THE NAM IS MOST AGGRESSIVE IN DEPICTING THIS SCENARIO AND IF

THIS HAPPENS THIS WOULD BE SOMEWHAT CONCERNING BECAUSE TEMPS COULD

INITIALLY BE AT OR BELOW FREEZING ACROSS INLAND AREAS OF SE GA.

THERMAL PROFILES DO NOT SUPPORT SNOW BECAUSE THE VERY DRY AIR

ALOFT WILL NOT SUPPORT ICE CRYSTAL FORMATION NEEDED FOR SNOW TO

FORM. SO ANY PRECIP WOULD REMAIN IN THE FORM OF RAIN BUT IF THE

SURFACE IS FREEZING THEN WE COULD INITIALLY SEE SOME LIGHT

FREEZING RAIN PERHAPS ACROSS PORTIONS OF SE GA. ALTHOUGH A MAJOR

OUTLIER AT THIS POINT...THIS SCENARIO IS NOT COMPLETELY OUT OF

THE QUESTION. FOR NOW WE WILL CONTINUE TO CLOSELY MONITOR THIS

POTENTIAL BEFORE ADDING THIS TO THE FORECAST.
