If we dig any further, we'll truly bring Venezuela up here.

Funny. You're not saying that on the thread.

The density and structure of snowflakes are influenced by wind. Strong winds can cause sheer forces and collision forces that can break up delicate snowflakes and cause damage to them before they fall to the ground. When a snowflake breaks up, it will typically become much smaller and denser than an intact snowflake because the intact snowflake has significant amount of air trapped within it, which enables snowflakes to be stacked on top of each other. When snowflakes are broken up due to wind, they will lose their structure, making it impossible to stack them. Therefore they will not develop the same amount of height per volume of water as intact snowflakes due to density. As a second point, strong winds often contain turbulent airflows and sublimation. Because they contain a high ratio of surface area to mass, smaller fragments of snowflake are more likely to be partially sublimated away or lifted into the upper atmosphere than intact snowflakes. Thus, much of the snowflakes created by strong winds won't reach the ground where we measure snow accumulation. Thus, the end result is a classic example of meteorological misrepresentation. When looking at radar images and the equivalent liquid from the snowfall, they may appear to be large amounts of moisture, but the awash in total in the ground will be relatively small when compared to the amount of snow that fell as part of the event. This is why windy events tend to produce low totals even when the snow continues to fall steadily.

So would we!

We are following the trend on a group of computer models. If only one of them said this, once, then you would be correct to throw it away. As it is, several models have shown this for a substantial period of time.

And your professional credentials that make you smarter than a global computer model using AI are...

Really seems to be three components here: How strong is the high pressure to the north and when does it move north? How strong is the surface low to the south? How do these two interact? Could we get in between them? If so, we could get some insane winds out of these and if enough snow falls, we could in fact get blizzard conditions.

This is a very encouraging sign.

My man... you go back and forth with every model run. Following weather is not live by the model, die by the model. It's the trend. You follow trends made over multiple days by multiple models. You also look at WHY, exactly, the GFS went south. Does it make sense or did it do something wrong? This is why we're on a forum with professional meteorologists. If it hits, it hits. If it doesn't, it doesn't. Either way, we get extremely cold, dense air.

There's nothing showing that the high pressure gets much stronger or moves south. All show that the high pressure leaving saturday into sunday.

Alright. I'll do that. Hope I'm not pissing off any mods.

The hype machine doesn't end until the middle of April. There's always that mid-february/early march storm, the mid march storm, the moderate event in the beginning of april... still a shot at snow around easter... Every year. I think we got a shot toward the end of next week though. We'll see.

I do not think this weekend will give several inches of snow. It will be extremely cold, yes. I think we will get some snow, another nickel and dime event. But then... into next week... that's our shot. Should I start a thread on the threat 12 days away? (ducks)

I'm learning from the best.

A 1053 mb Arctic high to the north absolutely guarantees cold and it does press the baroclinic zone south, but it does not automatically choke off coastal systems. In fact, highs of that magnitude often enhance the setup by sharpening the thermal gradient and strengthening the coastal front. Suppression becomes a real concern when the high is not only strong but also poorly positioned, centered too far west with confluent flow flattening the downstream wave. That is not what this pattern suggests. Here, the high acts more like an anchor than a lid. Cold air is locked in, the storm track is displaced south and east, and lows tend to ride the boundary offshore rather than cut inland. That favors snow and keeps systems close enough to matter. You can still miss if a wave stays too far offshore, but that is a track issue, not classic suppression. With a high this strong, the outcome is not rain or nothing. It is snow or a near miss, and NYC sitting near the gradient is exactly where small adjustments can pay off.
