Interesting but far from certain forecast over the next few days.
Based on the NWS Forecast Discussion:
The first wave brought the rain to all but northwest Georgia today. Indications are that the next wave and surge of precipitation tomorrow (Thursday) into Friday/Friday night, will be similar in distribution. Difference will be the temperature profiles and therein lies the uncertainty. Click here for current forecast.
Right now it looks like we start out Thursday through much of Thursday night with a cold rain with some wintry mix — snow mixing in across west-central and north Georgia by Friday morning.
There is some potential for accumulations along and north of the I-85 corridor by sun-up Friday, but that area should be seeing fairly light precipitation amounts in that time frame.
We will need to keep a close eye on how the future runs come together. As of the time of this blog post, confidence is not high enough in the next 36 hours for any advisories or watches. Click here for current advisories.
Looking more long term, the main focus clearly has been on the front end of the forecast period with wintry mix (rain/snow) transition potential. This potential is along an enhanced broad swath of SW to NE moisture and the interaction of a cooling airmass driven by a ridge to the NW and upper trough amplification to the west. The GFS/Euro models are still supportive of a zone where some low accumulating snow amounts generally through the daytime period Friday.
The resultant first stab at snow totals with high uncertainty is a slightly modified area of 0.5-1 inch oriented along the I-85 corridor which includes the Atlanta Metro area.
While the situation doesn`t warrant a watch/advisory at the time of writing, there is a Special Weather Statement issued.
Changes are likely as the next several model run trends are key in honing in on a more definitive area. This snow zone could shift north or south and have higher amounts accordingly.
Otherwise the other points of mention will be any black ice potential into early Saturday as subfreezing temps are likely to come in behind whatever precip occurs. Click here for current forecast. Then the cold amplified trough lingers across the area with a possible clipper system impacting the area Tuesday/Wednesday. Also uncertainty on timing and extent of moisture with this but could be another shot of wintry precip potential with this feature. From NWS Forecast Discussion dated 12/6.
