The Thursday morning map discussion video is on the server:

OVERNIGHT SNOW: Interesting to note the NWS in Huntsville had to issue a "Winter Weather Advisory" for Northeast Alabama late last night; for areas east of a line from Petersburg to Harvest to Arab. There was enough snow to cover cars in parts of Jackson County in the far northeast corner of the state.
NEXT ISSUE: No doubt we will have a big time weekend chill, but will the snow fans finally get what they want?
Snow lovers won't like the 06Z model runs; they are trending northward with the surface low for tomorrow night. They suggest the greatest chance of accumulating snow a little north of here, with the bulk of the precipitation falling in the form of rain Friday night, with a quick change to snow on the back side of the departing storm early Saturday morning.
The 06Z GFS is the colder model; the 06Z GFS runs the low from around Grove Hill to Macon. This would suggest perhaps a chance of some acumulation as far south as I-20 early Saturday as the rain changes to snow, but not much.
The 06Z NAM is faster and warmer; it runs the low up I-59 from Tuscaloosa to Chattanooga with only flurries on the back side.
Last night's 00Z runs (both of them) were farther south and colder. Generally speaking, old timers like me trust the 00Z and 12Z cycles more that the off hour cycles. I stilll lean in the direction of those 00Z runs.
What to do?
I am not a big fan of flip-flopping, so I won't change the package I wrote last night all that much. Everything will be adjusted northward a bit, however, with the best chance of a good snow cover closer to the Tennessee line. I still think we have a chance of getting a little snow on the ground down here. Look at the numbers; that is a whopping 1052 millibar high over Wyoming feeding the cold air.
AND, very cold air aloft and lingering moisture could set the stage for instability snow showers during the day Saturday; those things can make the ground white as well.
WEEKEND CHILL: The weekend will be very cold. I doubt if we reach 40 on Saturday or Sunday, and we will be close to 20 early Sunday morning, with teens in colder places. This will be the coldest air we have seen so far this season...
LONG RANGE: I still think the pattern favors one or two more systems like the one coming in this weekend. I know the GFS really doesn't suggest that, but I don't think it it correct.
I have a very busy day today; I will be taping a radio program with Don Dailey at WZZK this morning, and speaking at the Alabama Baptist Children's Homes and Family Ministries at midday. But, both places have good wi-fi and I will be cheking in with thoughts as the 12Z models roll in....
