A Hudson high acts to compress the flow in a way similar to a block! It’s why there is a whole subset of snows I found when breaking them down that look a lot like (looks up) THAT! Problem is they’ve gone extinct lately! This setup used to work a lot! Lately they seem to all end up warm or north. But I guess we can roll the dice again. Had to work eventually right?

Yep. There should be a nice band on the northern edge.

Steady very light snow. 36/28. Expecting about an inch here.

Philly thread is full of posters currently reporting snow all the way to the Delaware River.

Don S posted a link to a good paper discussing the change in storm tracks that had a hand in greatly diminishing snowfall across PA and the northern half of our sub. Worth a read imo. Open question is will arctic amplification contribute to more -AO that might later benefit us?

mPING reports of snow falling in parts of Berks and Lehigh Counties. That area could actually see a couple inches.

In 1312 i would have had 6” from this.

Like I said to CAPE NW loses its advantage if it’s too warm when it’s warm! When it’s truly cold the odds of a wave hitting here v DC or Richmond is pretty even. I used to her more (and state college) because it used to snow in bad patterns a lot more up here. I can list sooo many 3-5” snows during pac puke warm regimes that were rain for 95. Those have gone away, hence our advantage is significantly muted. Not gone. I still her more. But recently the spread between here and CAPE isn’t as big as it once was. Same phenomenon is affecting state college. You have to get up into New England to get steady snows doing bad patterns now.

your/you're is another one

Ha. Me too. PHX-JFK. Very bumpy for a bit. .

I don’t think the phenomenon is purely Nina. You’re right WRT average places SE or 95 are doing better. But the issue is the season places NW had an advantage wasn’t in cold patterns. When it’s arctic cold the odds of you getting snow are actually similar to me! I might eke out slightly more from upslope but it’s negligible. The reason I average so much more is because I’m supposed to have a HuGE advantage RIGHT NOW! Today is supposed to be a rainstorm for 95 and a 3-4” snow up here. The advantage here is in bad patterns we eke out snows that 95 SE can’t! But the last 10 years those aren’t happening. In bad patterns it’s so warm lately they don’t work! So we snow the same amount as you when it’s cold and we don’t snow at all just like you when it’s warm.

Insignificant flakes here too. 36F/DP 29F

Sierran storm still on track. Snow will begin early Mon morning about 2am Pac Standard Time. It will ramp up and strong winds will create whiteouts. The day by day snow forecasts are wild. Just feet upon feet right thru Thursday. There are warnings for snow all the way south to the Bernardinos and then clear up to west central Oregon. This storm is gonnabe HUGE and super frigid, extremely low snow levels. Some places high up will exceed 8 feet of new snow by Thursday. Don't be a tourist caught out in this. There will be no rescue for days and very low temps, extreme deep snow and blowing drifting snow from torrential snow and blowing masses of snow from off the ground by winds easily exceeding 50-60mph. Shasta already getting snow from this: https://www.skipark.com/winter/mountain-cams About 6 inches, they are progged to get 6-8 feet.

I grew up there and went to school at PSU. It’s diminished for sure. Hard to ignore. Although a lot of people seem to be very good at doing just that lately. Willful ignorance.

Temp has fallen to 37 here as rainfall has surpassed 1/8". Radar is blossoming as rain picks up in intensity. I'll be damned if I'm going to bed tonight before seeing some flakes fall through the night sky.

Southerly winds now,temps up a degree to 35/28f. 73%rh. Air is juiced already. Precip is building towards nyc atm.

Theres an old climate map/document from the 1970s discussing West Virginia's winter climate and it had several of its peaks reaching 160in+ snowfall amounts. I wonder how much that has changed in the meantime.

The delmarva and even points S have done fine, more than fine, during recent winters with the nina base state. Some winters even beat climo down that way. However, the further NW one goes, the worse winters have performed relative to local climos (save for the higher elevs). My winters here have been alright except for 22-23, but still fell short of my 20-22” local climo. Last year I got close. And when you get up to a place like State College, PA, they’ve done dramatically bad relative to their climo. What used to be 50” easily, they’re barely scratching their way to 20”. Like bad. Really bad. I’m just glad I don’t live there now, whereas I used to be envious that they were getting so much snow relative to the DMV.

I think that was another where I got a slight accumulation but noted in my head “what happened this should have been 3-5” why was it 34 degree slop” Was discussing this with @HighStakes the other day. He notices it too. Recently things that used to break into these little wet snow events up here are 35 degree rain. We’ve noticed so many examples the last 10 Years it’s kinda hard to keep sticking our head in the sand, especially when it coincides with our snowfall suddenly declining!

Drizzling. 35. Won’t take much to cool the air column.

Other than the ratter a few years ago I have been right around or just under the long term avg in recent winters. Ninas can tend to have colder periods and over here we can do well with late developing/offshore coastals. Lots of Ninas lately and not bad at all here wrt snowfall. Btw that 18.5" is for Denton, 10 miles south of me. Years ago when the CPC allowed the ability to look up historical data for many stations(free), I did Denton, Centerville, and Chestertown. IIRC Centerville was 19" and Chestertown about the same or a bit more. What happened to that? Is there any other resource where detailed historical weather data can be obtained?

I like the 61/31 with 9.5” of snow. Looks like a coop from elevated Utah or Arizona.

I remember the 2024 November elevation dependent storm as another example. I drove up to the Catoctins and the base of the mountain had white rain. After driving up to the trailhead you could see the areas further uphill had accumulations on trees/logs while even 100 ft below there was nothing. Hiking up the critical point was 1200ft where it went from barely anything to sticking to most surfaces coated. I could literally look uphill and see several inches more snow compared to downhill where it was barely a coating. Once past 1500ft it all turned into 5 inches of snow and howling winds. Crazy part is just 50-100 years ago you could move that elevation line down to around 500ft! That would've been a snowstorm for most of MD down to point of rocks! Instead, it was reserved for our few remaining mountaintops that had enough elevation to starve off the warmth.

Glad to see the salt washed away for sure.

I’m flying over it. Pretty bumpy
