From HPC....I suppose 'Heavy Snow' means accumulating snow, but not sure...(this is the Day 1 map...they haven't updated the Day 2 map since last night)

 

 

 

They have that "Heavy Snow Possible" shading pretty far west, FWIW.

 

I've been working all day. Can someone catch me up. Are we canceling or uncanceling this event? Or is it going to be recanceled, baked and undecanceled?

 

All of the above.

doesnt look drier to me? unless this is the 12z ensemble image?

 

 

It shifted the precip shield a bit further eastward.  GSO was in the 0.25-0.5" range in 12z and now it's been shifted ~25 miles further east.  Really, though, we're just splitting hairs at that point. It's pretty similar and QPF is always going to variate from run to run.

 

 

Looks very close to the 12z.

 

Well, it definitely looked drier to me and the axis is further out to sea as you can see upstream in the Boston area.  I wasn't trying to wishcast, rain on any parades, nor was I only focused on my back yard.  Here they are back to back:

I gotcha bro. It sucked for a while. But then there was more precip and we're looking good. But then there were boundary layer issues and the precip moved east by 25 miles. So we're back down. But then the RAP went negative earlier and the warm layer was shallower than we thought, so we're good again. But then the RAP stopped the negative earlier trends because the Tx shortwave got stronger and slower. Now we're down again. And that's where we are. At this point, count on some light rain with maybe a dusting or cloudy skies with highs in the 40s.

WOW!  That's a +1 on the synopsis of the thread.  I guess I'm not the only one that reads every post!

Respectfully though that was a totally different event and setup. That one didn't have -5 to -8 850's. 850's were always right around or just above 0. I think the bigger factor is going to be ground doing the damage on this one. Unless we see some really heavy returns for more than 30 - 45 minutes the ground temp may actually play a factor. Given how cold it is aloft though it should be easy to overcome the BL issues. 

 

 

850s are more than cold enough to support all snow... per soundings, 925s also support snow with anywhere from 0c to -2C which means the warm layer is very shallow

 

Burger is correct on the ground being the only limiting factor when inconsistent snow showers come down in some areas...

 

dominant p-type looks like snow... proper forecast is for flurries and snow showers most likely with some spotty light rain possible in areas where heavy precip doesn't develop

 

I'm tired of the little bullsh** systems (all we have had this winter is wanna-be systems)

Goes hand in hand with predicting snow around here.

Well I've read a lot forecast here and I've called for 1 to 2 inches for the RDU area. You were surprised at the lower prdeictions and saying nobody knows what's going to happen. I'm just curious what your forecast is? You've been around long enough to have an idea.

Just got in from cutting the grass(rye). Anyway one big plus is its clear as a bell and 0 wind. So we out to be able to maximize some radiation all cooling for a while. I've had 2 hard freezes the past couple of nights. Got down to 26 last night. Unfortunately hit 60 today. !atleast northeast nc is gonna go above their seasonal average in all likelihood after this one.

for the love of Pete, this ^^

 

just as MSUwx has also said, qpf is the concern... warm layer is very shallow (and very cold 850s look prime)

 

it's probably better to concentrate on the good when there are a tad more variables arguing for this tease of a system than negative variables arguing against it

 

regardless, nothing more than a dusting in spotty places looks possible to me, but I hope I'm wrong :lmao:

I've become less than impressed for this event here in Columbia, SC.  Looks like an annoying rain with some flakes mixed in before we could be cold enough at the surface.. by then the moisture will be gone.

The bulk will be right at peak heating of the day imo, and we should be above 40 degrees.

Question?

 

Can we combine the obs and disco thread for this one?

 

Leave it pinned, not like traffic is going to be exceptionally high, may help in moving the whole disco forward, rather than going back and forth.  Thoughts...  :snowman:

 

Sounds good to me.

Works for me, but it goes against prevailing trends.  More threads than a sock factory.

Great idea. I miss the old days when it was all under one umbrella. But times are different/busier traffic so I understand.
