You can see differences of 10+ degrees on Wunderground over the span of a few blocks.

With pws, that can be caused by 2m installations vs rooftop under calm/light winds. I see it with a station just a few houses away from me.

Got down to 15 here, up to 17 about an hour ago and back to 15.9 now.

I know it's gonna go up fast when the wind kicks up.  I don't use the south shore temps to gage what going to happen when the wind kicks up; I look at the temperature in Manhattan and the 100 meter temperature on the tower at BNL.

It's 30° in Manhattan.  On the tower, the current temperature at ground level (2 meters) is 14° and the 50 meter temperature is 28°.  For some reason the 100 meter sensor has been out a while; it's generally warmer than at 50 meters with an inversion.

So, a breeze mixing things up will get us close to 30°, but it'll take WAA to get us warmer than that.  With temps in the mid-teens for many hours, some surfaces may ice if the precip comes in early enough even if the air temperature is already above freezing.  Think of those red brick steps outside your front door, if you have them.

I'm back down to 17.

Up to 28 with a strong SSW breeze. Hoping for the temp to keep going up and minimal icing.

Take a drive into NYC tomorrow morning and let us know how you make out.  Maybe the models will be wrong.

Just did it.

Temps 32-34 from 2 miles north of Whitestone Bridge on down

 

Critical for icing, the 30 F line is cross county.

 

Hastings 28F

Freezing rain sprinkles have occurred Wantage. 27 at 714A. Manageable where treated, except a more careful approach I84 corridor. Not like Wednesday morning for NYC, I95.

[gravitylover]

Up another degree in 45 minutes. Here's to hoping

Classic CAD setup this morning with a light southerly wind starting to warm the lowest layers of the atmosphere especially along the coast with colder temperatures inland.  Temps along the south shore of the island have risen into the mid 30s while along the north shore they are in the lower 30s.  Temps in the city are in the low to mid 30s.  Just inland they are in the upper 20s.  WWA is up for places just to the north and west where temperatures are below freezing.  I am in the upper 20s with freezing rain as shown on radar almost on my doorstep.  Temps in western PA to the west of the spine of the Appalachians (a line drawn roughly from north to south from the State College area) are above freezing with rain.  This all aligns with the model projections from yesterday.  This looks to be a nasty day on the highways away from the coast with this setup.

[Brian5671]

33 here and partly sunny-looks like mostly rain with the later start and temps rising all morning

[Snowlover11]

thank god its takings its time.  should be a non issue here in lower westchester up too 33

[Cfa]

39 here w/ some peaks of sunshine. Low was 19.

[IrishRob17]

28/24 with freezing rain. mPING Reports are very useful on days like this and they are easy to submit. If you don’t submit mPING already I encourage you to do so. 

[Tatamy]

30/25 with light freezing rain.

[crossbowftw3]

29/27 with light ZR, sheets of ice everywhere. Definitely has accreted in the goalposts of the WWA by this point. Starting to see the icicles drip and melt which is a good sign but still three hours until I can pop above 32.

[nyrangers1022]

Seems like an awful lot of freezing rain the past few years.   Can't wait for the 90 degree days

[ForestHillWx]

28/23, precip is about to commence. 

[wishcast_hater]

Been light freezing rain with sleet pellets mixed in for the past hour. Everything is coated in ice. 28° here

[the_other_guy]

HPN popped above freezing last hour…which is good

SWF still 30F though

 

Newburgh-Stroudsburg-west of Allentown seems to be the problem line

[wdrag]

Wantage NJ 740' MSL going ups  degree an hour and 28.8 at 939AM. Ice even on shoulders of treated roads.

[Juliancolton]

29.5F in central Dutchess with steady light rain. My driveway is glazed over and probably not passable, so just taking it easy at home for now. 

[crossbowftw3]

30/29 now, probably going to pop above 32 within a few hours as the precip has come to an end for the moment 

[IrishRob17]

Just hit 32/28, really want to see temps above freezing for an extended amount of time as everything is iced over currently 

[Tatamy]

31/27 with light freezing drizzle.  Light icing on some untreated surfaces.

Yep. 2m temps mean little when the ground is still frozen if we cant get above freezing far enough or for long enough. 

[qg_omega]

Precip just took too long to get here, Wednesday was a few hrs earlier.  All the difference

Lets see what happens by us brother as the rain is falling near you = here in New City as I type

most of the big ZR events on the coast are in the early AM (like wed)  Still dry here and 37 now-solar insolation will help on the roads so looks like all rain here

[crossbowftw3]

Wunderground has 30.3, TWC showing 31; split the difference and it’s 31 here. On track to pop above freezing soon still. MSV still hovering at 27-28.

[psv88]

39 and cloudy
