Snowing here in Syosset with a temp of 35

Interesting.  Yeah that shading of slightly more snow right along the spine of the island w/less north and south - can't say I've ever seen a forecast map like that before. 

That was the high end forecast.  This is what to expect:

Why is Allsnow laughing ?

Who knows. That same model builds a ridge over the W as you advance it. Lining up with the 2/15 date Brooklyn was highlighting yesterday.

It makes me wonder sometimes if actual weather records are kept to a degree or to the nearest tenth of a degree.  Most of our personal weather stations keep track of temperatures to the nearest tenth of a degree.

Here's where it can create issues--

If my weather station records a low of 32.4 should that count as a freezing day? The low was technically above freezing-- because freezing is exactly 32.0

How does the NWS handle such issues? Do they round the temperature down to 32 or is a low of 32.4 considered a day on which it did not reach freezing?  Likewise does a day with a high of 89.5 get called a 90 degree day or not?  I always assumed that 32.4 is rounded down to 32 and 89.5 is rounded up to 90?

 

 

Yeah it's a big pet peeve of mine.  We have the technology now to be more precise using F.  Of course, C is more accurate but good luck moving our country over to metric.

seems like everything is coming together... Pacific jet is retracting and allowing for a strong Aleutian low to form, the NAM in the troposphere remains uncoupled from the stratosphere and favorable, and we should see blocking increase via wave breaking as we head into mid-December.

Think you meant mid-February, correct?  Nice write up!

Feb  3 - 5 looks quite cold as trough swings through and down the northeast.  

Looks like cold shots surrounded by warmth. If we can time the storms with the cold, we’ll get some snow perhaps. I posted the tweet in Feb thread, as I didn’t see Walt had started one.

I posted this in January thread, didn’t see we had a Feb one.  So reposting this since it’s for early Feb:

1.5” on my snowboard. Just got home & measured. Hopefully no compaction took place.

Anybody know why I can’t post a photo on here even with a screenshot

Is the attachment too big?  Otherwise, you should be able to.  I've had to delete old attachments posted since there's a limit.

the issue is unless you are under heavy rates, the thin cloud layer has allowed the suns energy to warm the blacktops. 

Yep, my blacktop driveway facing S (gets full sun on clear day) is snow covered in Syosset.  As is my road in untreated areas.

Light snow in Syosset

This MJO interaction with the El Niño is causing repeated  jet extensions which make it tough to sustain cold or more than a week at a time like we are currently seeing. 

 

If there’s a positive NAO, no muting that pac air.  Dr Lee doesn’t seem optimistic a negative NAO comes from this strat disruption.

2.3" in Syosset for this storm.

Flipped to light snow in Great Neck. 

Temp crashed, down to 28 in Muttontown & 29 in Syosset.

Sleeting in Great Neck now

County plow removing any slush from the county maintained road outside my office.  I'm sure they'll salt afterwards & road should be good.

Winds now NW and temp down to 31.3 in Syosset.  31.7 was the high.  Roads are wet and fine on drive to Great Neck.

31.3 now in Syosset.

Winds are still NNE. If it stays that way parts of nw LI into the city may never get above 32. But if it's around 32 any zr won't be an issue. Bigger concerns for black ice tonight though as temperatures fall. 

29.7 in Syosset with winds out of the NNE currently.

   Areas affected...Parts of the Mid Atlantic into southern New England

   Concerning...Winter mixed precipitation 

   Valid 161349Z - 161745Z

   SUMMARY...Locally moderate winter precipitation rates will spread
   northeastward this morning, with some modest ice accretion possible
   where freezing rain persists.

   DISCUSSION...A surface low currently off of the Mid Atlantic coast
   is forecast to gradually deepen as it moves northeast toward coastal
   southern New England this morning. Multiple waves of light to
   locally moderate precipitation are ongoing and will continue to
   spread northeastward in conjunction with the surface low. While
   interior portions of the Northeast will likely continue to see snow
   (with generally light to moderate rates) this morning, low-level
   warm advection will support a transition from snow to sleet across
   parts of southern New England, with freezing rain persisting over
   portions of the Mid Atlantic region.

   As the low deepens offshore, a modest uptick in precipitation
   intensity will be possible through the morning. While rates will
   likely remain light to locally moderate, antecedent cold conditions
   (with temperatures initially in the 20s F) may result in relatively
   efficient ice accretion in areas that transition to freezing rain.
   Pockets of moderate sleet/snow will also be possible into parts of
   southern New England. Low-level warm advection will support a
   gradual transition to rain along the Mid Atlantic and southern New
   England coasts, but subfreezing temperatures may persist inland
   through the morning.
