Seriously, WTF is with this Weather?


Ride Delaware ?

The warmer it is, the more moisture the air contains...simple as that. It's why global warmer is actually making some areas of the northern Rockies like Jackson Hole even snowier as more snow is gonna accumulate when it's 20 degrees vs zero. Realize that the Lehigh valley only averages 30 inches of snowfall per year but in a ten year period most winters are actually well below that with a few big years thrown in for good measure like 93-94,95-96, 02-03 and 13-14.

This, and a lack of elevation.

Elevation means nothing in over-running events like this right now it's two degrees warmer at Mount pocono than Allentown. Up at Stowe this will stay all snow...might stay all frozen up at elk for you. Dress warm prob go below zero up there Tuesday night.

I might go to Wicks after work today to look for a new board and bindings.  i dont really want to as i was hoping to make it through this year before getting new gear, but it looks like it may not work out that way

This belongs in the gear thread.

Elevation means a lot, it snows in Hawaii. You get up high enough, you will get snow. If the Pokes were over 8000FT, there'd prolly be snow.

Maybe I missed the discussion... but why the eff does it only precipitate when it's above freezing temps in Dec/Jan here?  Noticed this the past three seasons.  Upsets me greatly.  We'd have like 4 feet if all that rain was snow.

 

Because of the way the jet stream works and the 850mb line.

 

In PA if you want it to snow you need water, water comes from the southern stream, it also brings warm air which is bad news. Cold air comes from the north and due to the air density issue cold air tends to form a bubble. Therefore if you want big snows you need both at the same time, cold air from the north and southern stream energy that brings the water. This is always a long shot and half the time it goes OTS like the 12-16th storm.

 

The good news is when it does happen you get mega snows, blizzard of 93 was like 20 degrees out which is super rare for PA.

 

4 billion years ago proto earth got knocked on it's ass from a Mars size object, it was an oblique angle thank god or we wouldn't be here, This slowed our roll to 24 hour days and gave us axial tilt of about 14 degrees. Because of this tilt you get very little light at the poles, this creates a circling pattern of air movement, this is the Arctic Oscillation or the so called polar vortex. Most of the time it hangs out at the pole but if you get instability, normally warming of the upper atmosphere the oscillation starts to wobble and cold air spills out into the northern part of the US.

 

You'll hear about the AO going negative, this is super super key to NE weather because it's generally the only time you'll have the cold air. There is another oscillation in the North Atlantic referred to as the NAO. This provides blocking and helps storms ride the coast instead of going OTS. You also want this going negative.

 

Lastly while conceptually a little weird there is the Bearing Sea rule, basically if the EPO is going negative and throwing energy into the bearing sea, mark that storm in your books and it will pop up on the EC two weeks later. Obviously its not 100% but is generally true.

 

If the mountains in the east were younger and therefore higher 70% of the time you couldn't ride them. The rock pile ain't that high and you couldn't really do shit up there if it was 8k feet.

 

Another storm showed up on GFS for jan 21-23, follows bearing sea rule, gfs shows 15-20" for PA. One thing you have to understand about weather models in winter is that they almost always show a storm a week away, they simply say here's your chances, if we get it or not is a whole nother story.

I had to google like 4 or 5 things in this post. Good shit, man. Good shit.

Bad news - pretty much every possible storm has disappeared from the models, no snow on the horizon it seems.

 

Good news - Jan thaw is off the map, seems cold air for the rest of Jan...

that blip the past weekend in January's gone now? I was hoping something was gonna pan out for the infamous snorövr's triumphant return to blue.

Still there but a southern slider, has to come up the coast one to hit us and two to drop it's load on land. Last two days models show it sliding out to sea and dropping it's load in the Atlantic.

 

Still got a chance but it's now a real long shot.
