01/12 Arctic Front Observations

Remember, good waiters get good tips!

This system is losing some steam but there's still 3 full days of changes that could reinitiate the enhancement along the coast. There's a lot of upper level vorticity along the Arctic front.

Certainly cant disagree with that.  My hope is that the moisture depiction is underplayed and the warm atlantic will enhance things..a little.  That prob wont be well modeled until the hi res short range models take a look or even nowcast if that theory holds at all.  Most likely it would only benefit areas north and/or east of NYC

The Atlantic temps will not effect us much since the flow is heavily out the the W/NW. It should not have any effect on the precip shield, or moisture content of the air mass.

Ryan there will be a baroclinic zone associated with the frontal passage. Also Check the 850mb vorticity maps. There def could be isolated areas of enhanced lift which would be aided by the baroclinic zone established. If there is an enhancement I would expect it to be isolated, the warmer ocean temps could in theory aid in enhancing the baroclinic lift under one of these isolated areas of mid level vorticity.

I'm not sure how much significance it will make in such a dry atmosphere; this is not a highly dynamic system. The only way I could see your original theory working is if the bulk of the precip shield and its dynamics is not disrupted by the mountainous terrain. 700mb/850mb VV are quite strong, yet weaken drastically once east of the Apps. While there are pockets of high vorticity and vertical velocity modeled now, which would subjectively cause pockets of higher intensity precipitation, I was talking more area wide, when you reference more micro-scale areas now; which in that case I agree with your thought's.

Its basically a fropa with the center of the LP far to our north meaning a very short duration of precipitation, models have trended drier and we dont have a lot to work with here. We've seen these clippers many times. A squall looking front of snow that drops a quick inch over the course of a few hours and its done. Nothing impressive but will whiten the ground until the sun comes up the next day lol...

Completely non exciting!!! Shows how bad this winter has been

Positive vibes moving forward

I wouldn't write it off just yet.

Word. I may be grasping at straws, but there are still 3 days for trends one way or the other.

Agreed

Listen a squall line of one inch with 1-4 to 1-2 mile visibility for 20 minutes and some are complaining?? Are u fricking kidding me! Go back 2 weeks ago and you can have that. The potential upcoming is s9 me thing we have not seen in 5 years so.

Never write these off they are in sparse data regions of the NH and will now more by Mon.

Im not complaining, taking anything to tally up the season total which is a pathetic .1 so far...

Mugs you are correct squall clippers can have intense snow rates in heavier bands theyre nice small little events but in terms of impact or major accumulation they often turn out negligible.

The NAM got it in its LR but it looks a little goofy, I sure like it though lol.

Some mood flakes late Tuesday it looks like.

LOL this may be the most perfect snowmap Ive ever seen, thank you 18z NAM.

If that happens THIS year I would never day another word about BDB.

00z GFS still on board for a few flurries Tuesday night.

A few flurries on the Euro as well

Can we shut this thread down. It's depressing. We're borderline excited for flurries when 2 days ago 1 to 3" was possible?

Yea, this is really a non event at this point. Flurries aren't exactly exciting imo, but that's just me.

Depressing that another chance at decent snow is done.

It's not over yet.

lol as I said earlier the closest I am getting to snow flakes at the coast is by looking at snow's avatar .. hope our luck changes in the very near future.....

Let's look at 4he RGEM which does a good job with thwse systems as dies the gfs.

00z NAM really doesn't give anyone an accumulation from this except maybe a dusting for CP and Doc.
