At 7:30 a.m. Wednesday morning, the National Weather Service issued the following update:
A strong wedge of cold air continues to spread in across the forecast area from the east this morning… with ample overrunning moisture resulting in widespread rain… snow… sleet and freezing rain across much of the forecast area this morning as expected.
Warnings/Advisory: No significant changes were made to the forecast concerning expected snow and ice amounts… if anything they were increased slightly for some areas. Therefore… no changes were made to the Winter Storm Warning… Ice Storm Warning… and the Freezing Rain Advisory. Their locations and timing remain unchanged from Tuesday evenings issuance.
Temperatures: We’ve been receiving reports of snow… sleet and freezing rain across much of North Georgia since midnight and current observations show freezing temperatures have now spread in across most of north Georgia to include the Atlanta Metro area. Although the far western sections of North Georgia around Rome… Cartersville… Dallas and Carrollton to name a few are still around 33 to 34 degrees… expect even these areas to see freezing temps by 6-7 am this morning. The freezing temps are still expected to spead as far south as La Grange to Thomaston to Macon to Dublin and Swainsboro by late this morning. This while precipitation continues to spread northward from a surface low pressure system along the North Central and Northeast Gulf Regions.
Threats: Still expecting mainly snow from Rome to Cleveland and northward… and although Cherokee County is currently seeing mainly freezing rain this morning with numerous power outages reported… we still expect the freezing rain to transition over to mainly snow across at least the northern portions of Cherokee county sometime this morning as a deeper layer of cold air spreads in from the northeast.
Freezing rain remains the main threat for areas along… north and south of the I-20 Corridor from Carrollton to Atlanta to Augusta… with latest model runs showing just over 1/2 inch of ice in Atlanta… and 3/4 to 1 inch or more east of Atlanta from around Covington and Madison to Augusta, generally along the I-20 corridor but with the most significant impacts anywhere between I-85 and I-16 east of Atlanta. Many areas will see crippling amounts of ice with wide spread power outages still likely.
Freezing Rain Advisory: A light glaze of ice… sleet and possibly some light snow is still possible through early Thursday morning across the far southern counties in the advisory area… and mainly between 10pm this evening and 9 am Thursday morning when temperatures fall to around freezing. Black ice on bridges and overpasses still appear to be the main threat tonight in this area… but will monitor potential for more widespread accumulations of ice closely today as freezing temps try to surge further southward.
