just so I'm clear--I was really just teasing about the brine. I think its useless regardless. But it always makes me feel good to see those trucks on the road.

The regional models look great, the globals not as much. I should just assume whatever models show the least snow will be right, so I should be battering down for T-2". However, I'm a weenie so I can't do that.

That's probably really good, actually. After looking at all of the guidance and trying to be fair and objective about it, a T-3" is probably a good guess for most areas with maybe 4 to as much as 6" in the north central coastal plain area. Over to the Triangle, going to be tough to get more than 2-3", even as good as some of the higher resolution models look. The HRRR and GFS not being cold, along with the NAM creeping north with the warm layer are flags.

I'm hoping overrunning overperforms like it has all winter. But it probably won't now since we're talking snow now instead of rain and mother nature is out to get us.

I'm going to hug Webber's and Alan's call maps and the NAMing.

Meh, I am starting to sense a huge bust potential with this system. (and not that good kind) I don't like what some of the short-range models are showing. I am normally optimistic about storms, especially with it being less than 24 hours out. But there are just so many options on the table. I fear a lot of us may end up highly disappointed. I hope that's not the case though. I cannot believe it's 2020 and we still have this much model inconsistency. It blows my mind! And to boot, not one county is under a watch or advisory of any kind. It's almost laughable.

i think at most we see an inch

Just make your own model like that one fool. You can make it do what ever you want.

I've come to the conclusion this is going to be a best case "March" type of event, just a couple weeks early. Wet snow generally will be falling, some accumulation on grassy/elevated surfaces will take place, but mostly just slushy on streets due to surface temps. You hear the gutters draining throughout the event.

Afterwards, reporters on TV will show kids sledding down hills that are mostly brown from all the mud, and these sad little snow men will pop up everywhere. Schools will be on a 2 hour delay on Friday to accommodate for the black ice the next day just to be safe. Then we all move on to Spring where according to Larry we'll probably have another March event in a couple weeks! lol.

A real possibility. Given the timing, for at least part of the storm we are going to be battling sun angle (more so for CLT given the timing), above freezing BL temps (for many), and warm soil temps. Without consistent moderate/heavy rates, accumulations will be hampered quite a bit by that. We need heavy rates like the short range models show, then it won't matter as much.

I don't want white rain.

I really hope we are both wrong. I really do!
 
The NAMS/RGEM/RAP all show cold enough solutions for ~northern half of NC; while the HRRR/GFS and others are either warm or too dry in other locations.

Will the NAMs et al get the initial conditions right? Will the WAA/FRONGNSIS produce heavy rates and help cool the atmosphere from the top down? If it does snow, will it be able to snow heavy enough during the daytime hours to overcome sun angle/warm ground/pavement? Lot's of questions abound. I like the odds for those in the northern half of NC to see near or at warning criteria snow.
 
I'd assume the NWS is working closely with the state emergency departments, and it wouldn't require a public watch, advisory, or warning for them to start treating the roads.

The problem is, issuing all those things public start costing people money. Business closings, school closings, etc. If it doesn't do anything, guess what? They're mad.
 
I don't think they can brine the roads as long as it's raining/drizzling. It will wash off.

That's good analysis right there.... too good for the whamby thread.
 
Less than 24 hours from go time and the models keep holding strong or even look better with each run for my area. Gotta love how things look now for a decent to great winter storm.
 
man i wish this would move in tomorrow night would be so much better for down this way

So, um, RAH has to at least hoist WWAs this afternoon, right??? No way we at least don't get WAA criteria...No WFO in the SE have posted any advisories yet, though.

My guess is you will see some with the western Offices this afternoon and I would not be surprised if Rah didn't hold off until the night shift.

For the western offices, they are waiting till all 12z guidance comes in. EURO is last one to look at then some advisories will be issued.

Anyone have any thoughts for north Georgia?

Far far North Georgia might get 1-3in from what I’ve seen. Maybe some snow showers and flurries as far south as north metro. Doesn’t looks like anything crazy to me at this point. This is a Tennessee to North Canadina storm.

This image says it all for MS, AL, GA. All that warm air in TN is just brutal. Unless that changes (which is unlikely at this point) it is rain.

But we can hug this until verification:

No way forecast offices don't start issuing advisories this afternoon, not a single model with non-impact winter storm

I was just thinking that...WSWatch are going to be hoisted very soon by RAH you would think. Then will it be an advisory later or a warning. The globals are 3-4"...probably can reduce that an inch or two...so 2-3" would be a good bet I would think.

Yea we got ours 1st and now it’s there turn. Hopefully Alabama and South Carolina can get something in the next 3 weeks before we say hello to Sprummer.

If the models hold through 0z tonight and even increase slightly I'd bet Warning just to cover the potential high end amounts..... maybe?

winter storm watch? or winter weather advisory?
Click to expand...
I think a Watch, they can decide if it's advisory or warning criteria with the overnight package but for public info I'd be surprised if they didn't do the watch just my .02
 
I have a flight Friday morning at 6 am. How likely is this to be delayed or cancelled given what we know now?
