Jan 25th Winter Weather Discussion Thread

The #1 analog event showing up for this is 1/23/00....I don't know what you had there but ATL had roughly 6-7 hours of FZRA at the airport and even when they switched over they never got above 33.  The setup appears also that it would have favored precipitation mainly over NRN GA but it developed quite a bit more south as well.

That event was awesome.  I was living in Acworth and we had a somewhere between 1/4" and 1/2" of ice on top of a coating of sleet and snow.  I remember Glenn MF Burns saying all Saturday that it would warm up above freezing.  Finally he got on air at 6pm and said he was wrong and it would not warm above freezing until after the event.  We stayed 31 or below the whole system.  Didn't that event have more of a true CAD high?

i just hope we can get the precip to fall and early! Most of the time it lags back and i feel if that happends then game over. If i see anything ill be happy. But i do enjoy reading your thoughts hopefully this thing will work out seem kinda out of the blue. NWS had our temps friday in the upper 40's a day ago then changed it to 35 yesterday afternoon.

 

Yeah, I loved the article from the Atlanta Journal-Constitution this morning. They have edited it now (as WSB caved somewhat), but this morning it was FFC vs. WSB. Karen Minton said they didn't buy the models and had temps in the 50's with rain versus FFC's 30's and ice accumulation.

You can always pretty much count on the opposite of whatever wsb and crew forecast. But i will say as a kid i loved watching all the hype hoping for a day out of school! :popcorn:  Lets get it on!

 That was the first of the two ice storms that plagued this city that year, the second one was the one that has eliminated us from hosting a Super Bowl ever since.  Really annoying seeing as how the odds of that happening again are not high.  That being said, that second ice storm was nasty.  We were without power here in northern Gwinnett for almost the entire day.

If you think the kids want school cancelled you should see the teachers. I have to admit, since I've retired snow has lost a bit of its excitement for me. I'm off every day now so some of the thrill has gone.

I use to love the snow and cold. But living here and trying to find a little hope for a snow storm is getting old, and the company we run has to be closed if there is any snow or ice on the ground in fear of a dumb*** slipping and sueing. That being said i do think what we get will be frozen with this event, but just not Confident we will receive anything other than some showers which will probably freeze

You can see it here pretty clearly. It develops right after the precip starts. The gfs doesn't put down enough precip to even warrant a mention to be honest. (you have to click on image to see it all). The roads will be a complete sheet of ice if this transpires.

Looking at the surface analysis, it appears the high is actually quite a bit stronger this time

You are welcome. Problem is, what do you do about getting kids back home?? Roads should be nasty even by mid afternoon. And maybe even some power outages if enough ice accumulates...

Like Don said if that time frame verifies the school system will have a 2 or 3 hour delay and then if conditions get bad or are worse they can then close the schools. :snowwindow:

I seriously just want to see some snow fall. The shaft I endured last week was awful. Just heavy ole rain. I had friends ALL AROUND me reporting Thundersnow! I need a good snow quick! Forget ZR....I can do without. I survived 2001and it was NO JOKE! Hope you all are well (and your Families too!)

 No, actually it was a similar setup at the surface with a rather unimpressive looking CAD high of only 1026 mb at its center in VA (actually a bit weaker than this setup). Of course, that one was much wetter with over 1.5" of liquid falling in Atlanta. The followup storm of 1/28-30 had a more classic looking big CAD high.

yea I hear you.  ten minutes from me the ground was covered with snow as were the roads and all we got at the house was rain.  didn't see one flake of snow and was predicted 3-6.  2-4 inch snowfall would kinda mend some wounds from last week.

CAE keeps the same discussion from this morning......

And notice how EVERYONE got it wrong until the night before...

 

Steve,

 Looking back at my notes, ALL local ATL TV stations including Glenn Burns and the FFC NWS, indeed, called for a high near 45 on that Saturday and only a little sleet mixed with the rain at the onset. They also called for a low Saturday night down only to ~38 F. However, to be fair, Kirk Mellish did call during the day on Friday for a wintry mix to fall on Saturday. He needs to be credited with that and I give (and have given) him kudos for it.

 

 One thing to keep in mind is that whereas 1/22-3/00 was progged by no local other than Mellish to produce sig. wintry precip. in Atlanta with the significant wintry precip. all well to the north, it was progged to be much wetter in the Atlanta area than the current one. The big problem with the current one is the lack of progged moisture. I look at progged dry WNW 500 mb winds as a major hindrance to large amounts of moisture. Atlanta almost never gets very wet when the 500 mb flow is from the WNW. I base this on studying numerous old 500 mb maps. So, this time I haven't been expecting a major storm like 1/22-3/00. However, I was hoping for at least ~0.25" like the GFS had for a good portion of Atlanta metro at one point. I still hope that comes back. An earlier start to the more sig. precip., as was being shown on those wetter GFS runs, would help a lot.
