IF we get anything out of this possible event, make sure you enjoy every minute of it!  For many in this forum it looks like the last chance until December!

You’ve been preaching this crap all winter. Where’s our massive -PNA?

Sinners you are going to hell!!

I grabbed that because he updated today to say "still applies". Sorry.  

Here was today's update:

 

It seems like every meteorologist hedges every storm six ways to Sunday.  There's always some complicating factors that make this or that storm special and impossible to know what's going to happen because the setup is just so complicated every single time.  

 

I dream of the day when there's a storm 5 days out and the Mets say "oh this one is easy, blizzard in DC in 5 days, lock it in".

^look at the EPS 500mb anomaly chart for Sunday the 13th at 12z and tell me how that’s numerically a negative PNA.

I wish people wouldn’t focus on those charts so much. The NAO chart was positive when there was a block right over Greenland back in December.  Those things are calculated in ways that don’t always translate the same.   That said he isn’t posting in good faith anyways he is a troll.

@psuhoffman we were discussing whether the possibility exists for big model changes once we get within about 4 days. Was thinking about that and was thinking that if you’re talking temps I agree. It not gonna suddenly go from 40 and rain to 30 and snow. But when it’s delicate pieces that determine whether it’s dry or there’s 0.25-0.5 precip, then I think big changes can easily show up as you get close.

Mount Holly AFD.. we just cant know yet.

For Saturday and Sunday...Low pressure tracks well to our north, however a strong cold front is forecast to cross our area by late in the day Saturday. Southerly flow ahead of the front will maximize the low-level warm air advection and despite cloud cover, afternoon temperatures are anticipated to get well into the 50s across the coastal plain where even some low 60s will be possible. To the north and west of here, temperatures may be held down some due to more cloud cover and a possible earlier arrival of the cold front. There may not be much in the way of precipitation with the frontal passage as the main initial forcing for ascent lifts well to our north and the upper-level trough axis is still well to our west. Shortwave energy along with a favorable mid to upper level jet though may produce a ribbon of better lift late Saturday night especially across the coastal plain. It will turn much colder and drier Saturday night in the wake of the cold front along with a northwesterly breeze.

As we go through Sunday, our sensible weather will be determined from what develops offshore of the Carolinas. Temperature-wise it will be cold. Much of the guidance is in agreement that low pressure develops along Saturday`s frontal zone that is located offshore. This occurs as the large scale upper-level trough shifts closer to the East Coast. However the low pressure placement, track and intensity will depend on how far south and east the colder air presses and also if any interaction (phasing) starts to occur between the northern and southern stream energy. Some guidance now showing a sharper upper-level trough which results in a bit more phasing and therefore a closer to the coast placement of the surface low. The ensemble guidance offers variability and as a result there remains considerable uncertainty with the details. Despite the surface low tracking offshore, the positioning of an upper-level jet looks favorable resulting in a zone of enhanced forcing for ascent for a time Sunday, especially across our coastal plain, which could result in a period of snow. Given the uncertainty and accounting for some guidance shifting closer to the coast (the National Blend of Models, NBM, responding to this), increased the PoPs a little however we are still no higher than the chance range.

Depends what you call big changes. The fringe of a storm moving 50 miles isn’t big Imo. We know the edges and banding don’t get pinned until the very end. But we haven’t seen huge synoptic changes once inside about 100 hours.  We’re right at that now. And maybe we’re seeing convergence. Ukmet lost it’s crazy amped up solution from 0z. Gfs also trended a little south. Icon and Euro trended towards the Gfs. Toss the ggem as the outlier.  Maybe there is another curve in the next 24 hours but if not the consensus of all that guidance is likely close to the final outcome.
