+ New 12Z model data generally supports the forecasts that are current. The ETA, now called the NAM, positions a high from New York to Charlotte at 12Z (6AM) Saturday with rain over virtually all of Alabama (best amounts over East-Central Alabama) Temperatures at that time 30-32 so the risk of light freezing rain still out there...mostly east and NE Alabama.
+ The infrastructure still relatively warm so the possibility of icing may be mainly on bridges and overpasses but not entirely.
+ The "wedge" plays a big part in this as cold air spills down from the East Coast high pressure area on the east side of the mountains and then spreads westward across South Carolina and Georgia into Alabama...this sets up a temperature profile of colder east/warmer west. It is sometimes called a "backdoor cold front" and it is difficult to deal with.
+ I feel sure that God created the "wedge" to keep us honest and to remind us weather humans who's in charge.
+ A few spot forecasts if you are traveling east of Alabama:
ATLANTA
Good chance of light rain and freezing rain Friday night continuing Saturday morning. Low Friday night about 28, high Saturday afternoon 38.
GREENVILLE-SPARTANBURG
A mix of snow and sleet Saturday morning with a mix of freezing rain, sleet and snow in the afternoon...continuing Saturday night. Moderate snow accumulations possible. Low/high Saturday 25/32.
CHARLOTTE
Chance of snow mixed with sleet Saturday. High near 32. Mix of freezing rain and sleet Saturday night, temperatures hoovering near freezing.
+ Be sure and check James Spann's video update later this afternoon + his additional posts here...also the afternoon discussion on the 3340 weather page around 2:30 or so.
