Lets not get Wolfie started today…yesterday was brutal.

Sun angle is ever so slightly higher than it was yesterday .

Should be more melting today in the sun since it will be 22.

Might get a 1-2” refresher here tomorrow. Gonna need it for sun angle season now.

As we thought.  Deep winter.

Where do you get the snow depth data?

ORH seems to just have a series of M’s 

BOS doesn’t seem to show it

That’s a nice shot with the plane at final approach on runway 270.

Most airports don’t do snow depth anymore. Consequence of getting rid of full time weather observers and going to ASOS in the 1990s. Airports that still have an observer on site will have snow depth. Guess BDL has one again. For a long time they didn’t.

You mean.... Longest! Lol

Ha, at least you stuck to your guns and went down with that ship! I'm sure we all secretly hoped for a last minute change

Logan is lucky they have someone who measures never mind snow depth.

Some NWS offices call and ask the tower to measure, but not all seem to do so.  Mt Holly always gets measurements from TTN/ABE though neither has an observer anymore.  NYC though does not do the same at GON/HVN/FOK/FRG despite the fact probably they could get TWR staff to do it.  BOS/PHL/DEN/DTW all do not measure on the field for whatever reason so they never have SNINCR remarks or 4 groups.  My assumption is that none of them have good spots on the field to measure snow accurately.  They all use someone just off the airport grounds to do it.

Does this cold pattern bleed into spring and summer?  We have had a number of hot summers in the past 10 years.  Wondering if the mini split gets a rest this year.

Most developing El Nino summers are cool in the East.  I'd expect if we see the expected transition to at least a weak-moderate El Nino this summer would be below normal

I love it!  keep it comin' 

Yeah, so, you know all this, but for the general audience.   Feb 9th is the closer approximation time 45th parallel exits of the solar minimum.  About the 8th at 42... 

It's an interesting aspect of celestial mechanics that these time windows do not correspond with the seasonal calendar. These human inventions handed down from antiquity are actually irrelevant to astro-dynamics.  The first day of spring in terms of planetary orbital mechanics should be on or about the date the sun switches from nadir to gaining.   The first day of summer should be on or very near May 8th...  Autumn should begin on August 9th or so and so on.  Winter is November 8th.   

Thing is, the year is split up in to 91.25 days per temporal quarter. That makes up 365 days total.  However, there are some numerical idiosyncrasies baked in that make it not exactly 91.25 days per max vs min, vs the two transition solar seasons.   For one, the orbit of the Earth around the Sun is not a perfect circle.  The planets spends slightly more time in summer max than we do in winter min ... because it is closer in its pass to the sun in the winter. Such that by a small amount the orbital velocity is faster than the summer.  So the solar max is actually about a couple of days longer on each end...  I think the solar max actually begins around May 4th or 5th... then running out to August 10 or 11.  But for simplicity, we just figure a roughly 91 and change days goes into each quarter.   So Nov 8 to February 9 to May 10 to August 11 then reset at Nov 8.   

When we pass through these virtual boundaries in space, you don't really notice much difference at all. But if one looks around they may detect.  Example, as others are noticing, we are already sensing some warm direct sun exposure sensation just 41 days past the Solstice now.   But, that sensation will be noticeably stronger by the 15th of February.  That's sort of how these boundaries are blurred as they pass.  I have ruminated in the past how hopping in your car at the end of a work day having parked it in the sun, the interior is noticeably warmer from solar bake on or about February 10, noticeably more so than February 1.   There are some specialized physical settings where these transitions may evince.   Also, snow packs facing the sun will start to shard appearance no matter what the ambient temperature is by February 15.  That's the intensifying solar radiation heating darker embedded particles and then the melt back through. Micro effects.

Euro drops a couple inches in SNE Friday night/ Sat

Bombs clipper late but would still drop some snow 

[Cyclone-68]

They should make sun angle season a national holiday. Much like the Pagans at Stonehenge

Hopefully we can rack up a good dozen D-2” events in a row now. I’m getting tingles thinking about clearing my driveway 5x a week 

[Torch Tiger]

Stein right through mid-month on the 12z gfs. Rapidly approaching Spring by then!

BDR'S reports come up as Official NWS Obs. I assume that means they have an observer on site? Seems they have a good observer as I work in the area all the time and they seem spot on.

In the Arctic they have dark winter and light winter. It's cold as hell for both of them but down here we feel the sun.

You can really see it increasing on my small 1.2 kw solar array facing due south in full sun all day....

For some reason it’s just BOS and ORH not reporting depth in the region. If they can contract someone to report daily new snow you’d think they can make a 7am depth measurement daily too.

Official NWS obs can come from ASOS too. All the ASOS sites are “Official nws obs” since they are maintained jointly by NWS and FAA.  

It’s just ASOS-only sites won’t give snow depth.

EPS likes 2/7 and then again a week later in the 2/13-14 timeframe. We’ll see if we can get a stronger signal as we get closer.
