Any idea why the soil temp would increase like that during a snowfall? I'm imagining something along the lines of latent heat release from melting and refreezing snow causing a feedback loop but that's probably way more complicated than the actual answer. 

Either way, most of my nearly 6" is already gone with swaths of bare grass opening up. I have one of the best radiating sites in the region and do pretty well in most snowstorms relative to surrounding towns, but living on a giant south-facing slope is the price I pay.

Freezing releases heat, melting sucks it up.  Otherwise you could heat your coffee by putting ice cubes in in it.

My only guess for the ground warming explanation is that as it got covered with snow, is that the snow insulated the surface enough for slightly warmer soil just below it to warm the surface soil.  That assumes the soil temp probe isn't that deep.

That's my guess as well.

On the train into the city and the amount of leftover snow increases steadily as you head west from wantagh. So there was definitly less snow in eastern Nassau. Even though numbers weren’t that dissimilar a good portion of the snow in eastern Nassau fell durning the final band when ratios were highest and thus melt the fastest

I think the delayed start from earlier guidance allowed the main band to set up a little further west than the forecasts on Friday.

For part of the afternoon rates became so light that we were actually losing snow since it was above freezing. Like you said, the ratios got better later at night and there was a clear difference in the consistency. I could see the difference in the layers when I was cleaning my car off. It was almost like it was two different snow events.

I was checking January 2011 daily obs and saw that the local climate data for the 25th-27th storm...It has 16.0" for the total storm and 32.0" for the month...

NYC local climate sight still has Jan 2011 with 36.0" of snow...

was the storm re analized and not noaa's sight?...

I am going to call it the great blocking shift of 2013. Dominant NH high latitude blocking switched from the NAO region to the EPO area. Something around the beginning of 2013 caused most of the extreme blocking to shift over to the NE PAC from the NATL.

The interesting thing is how this occurred on a dime.  It's like a switch got turned on (or off)

Where did you find the most fell?  You took the train from Lynbrook? I take that one too.

That said, the soil temps around me are pretty much the same that they were last week before the snowfall and there's snow on the ground now.  So the snow can certainly insulate the ground from the cold now which could keep the temps steady.  

Yes that's why the eskimos were smart and built igloos :) I actually feel warmer when it's snowing vs when it's raining and cold.  And dry and cold is the worst.

Yup as you go down the soil is quite a bit warmer.

The bright side is that the deeper soil is loosing heat to the surface soil...and snowmelt will carry off that heat from the surface.  

Ding ding you got it. The lower layers were transferring their heat upwards and subsequently cooling. One of the local mesonet stations the 10" depth is down 5 degrees and the 20" is down 8 or 9 degrees from yesterday morning and the 2" temp has stayed steady since it topped out yesterday afternoon. The other local station the 10" is down a few degrees but the 20" temp is insanely warm, warmer than it was 2 days ago actually which I can't explain.

Ha! Wantagh, hence heading west from Wantagh...

just messing with you. The most snow was at my destination 120th and Broadway. However there was noticeably more snow from about central queens on. Hopefully this isn’t a sign of things to come this winter for us

It still was a lot better than Dec 9, 2005.  Remember that horror show?  6 inches in Central Park, 3 inches at LGA, zippo from JFK east (for both the north and south shore!)

On top of all that, SNE had one of their most dynamic storms of all time, right down to the coast.

Unfortunilty i remember that one well. My ex gf was living on the Ues at the time and I remember taking the train in and seeing the snow from mid Queens on

All snowcover gone here, run up to 51F and a shot of moderate rain took care of what was left this morning.  

The record low temperatures that we saw on November 11-12 were timed well with the higher snowcover. We have seen a big reversal with very low values for December 11th.

Gone here too. What was left disappeared overnight. GFS is ugly in the long range. No more snow, bunch of rain storms through Christmas. Mid section of the country gets a lot of snow and ice though

Yeah it looks pretty ugly. Troughs keep crashing into the west coast, very Nina esque.

Plus you have a +AO/NAO and -PNA forming, so this won't be some 2-3 day relaxation pattern.

How is the long range a lock? The models have been all over the place. We could just as easily see a reversal again.

i don’t get the modelogy

Thanks. Am I missing something? Weren't we just talking about being cold through Christmas?

I guess this is where we get in trouble for hugging the models.

No we start moderating this weekend and go back to normal/above by next week. After that who knows, and I certainly don't trust anything more than 7-10 days out
