To elaborate... 288 FXUS62 KFFC 211620 AFDFFC Area Forecast Discussion National Weather Service Peachtree City GA 1120 AM EST Tue Jan 21 2025 .UPDATE... Issued at 1107 AM EST Tue Jan 21 2025 This morning the main question has been where will the dry air win out. We are doing an 18z sounding to get a better picture of this line and will have more of an update as that comes in. Currently there is a deep layer of dry air at 850mb but our dendritic growth zone is almost saturated at this point. We have been receiving reports of flurries despite this and are seeing a potential moisture surge coming in from Alabama. This along with the 12z models coming in gives us a little more confidence that the 850mb layer will moisten up but we will know more with this sounding. Have just slightly upped snowfall totals to account for this trend but only by a couple tenths of an inch. Will keep an eye on that though. &&

Took the dog out a few mins ago and occasional flurries falling. 24.6° / 10.8°

22 with a dew point of 4. Incredibly dry air mass in place. .

And more overall moisture

12z NAM was a decent run for a lot of this forum. Expectations with this storm got WAY too high, WAY too early.

Yuck.

ICON out to 72 and a bit more north and a bit more moisture. Minor on both accounts. Not a good look for most of the viewing area. Dry and sheared

I predict they get on board soon. As per usual, the mid/long range outlook on the extreme cold (and heat in the summer) is moderating out thus the base of the trough not digging as far south as earlier modeled.

I think that is where we ultimately end up when all is said and done. The GFS has started working towards it today.

Canadian model DEEP into the Crown Royal tonight.

The GFS has trended NW with every run today. I'd expect that to continue as we go into the weekend.

0z ICON nearly identical to 18z out to 108

Just puzzling what the GFS is spitting out compared to the other models.

Last 3 GFS runs have shown only that a storm is there. Absolutely zero consistency with details.

18z GFS HR180 with heavy, wet snow in Houston, TX Storm WAY slower to eject
