Moderate snow all surfaces are caving here cars have about 0.25" 32.2f humidity 88% dewpoint 29f.

Moderate to heavy snow here 33.3 humidity 85% dewpoint has gone from 19 at 12:32 to 29f now wow!

Light snow temp down to 33.4f humidity 78% now dewpoint 27 wind ENE 14 mph. 

Looks like another area of lifting gliding north from northern Maryland headed this way. 

Light snow now temp 34.2f falling humidity skyrocketed to 72% from 51% in like 10 minutes dewpoint 23f. 

HMMM looking at radar there is a heavy band leaving Baltimore rising quickly towards the Mason Dixon Line this has to be the secondary band setting up like the NAM had it.  

Also, wind has picked up here noticeably looks like ENE now definitely shifted.

Maybe you can get past 8" lol. I guess this is like lake effect LOL.

Snow brothers lol

 

So amazing! Wow!  Only 42 miles away. 

Just wow how dramatically different here.  LOL

Good News though I have a few pity flakes and my humidity rocketed up to 61% dewpoint up to 23 and temp 35.0f now. 

What the hell snow stopped here all cars whitened melted 36.0 humidity 52% dewpoint 20f 

LOL Shazam light snow all cars are white lol temp 36.4 humidity on the way up 51% dewpoint 20f 

12:32 am first flakes all stats still the same 36.4f humidity 50% dewpoint 19f pressure 29.85 falling.

No real surprises so far....snow blossoming along mason dixon line across N MD and SC PA

That's ticketed right for here nice.

I'm worried about getting dry slotted here in the Delaware/Chester County area.

 

I think that it may be the case humidity here ticked down to 50% here after being up at 53% dewpoint was 20 back down to 19 our thing is will, we get the lifting a bit later on. You can clearly see the heavy bands setting up just south of Allentown west to east. 

Guess we gotta pray another band pops up along the Mason Dixon line and drifts north then moves east we shall know soon. 

36.2f humidity 50% dewpoint 19 pressure 29.87 falling wind ese 4 mph

Cloudy temp up a degree to 36.4f humidity 52% dewpoint 20 wind ESE 2 mph pressure 29.87 falling.

Snow began at 10:40pm

32F

0z GFS looks like the FV3

 

Yea but from the total QPF it clearly shows that band of subsidence in southern PA southern Chester County right into Delaware Count to the Delaware River and across I mean if that is correct, we will barely crack 2" and we have a Winter Storm Warning.  I guess we just cannot know yet where these precious bands are going to set up with 1-2" snowfall rates.  I will check back at 2:30 am.

Cloudy Temp 36.4f humidity 50% dewpoint 19 wind calm.

My bar here is 2.3" I have a bad feeling about a split here band north band south and caught in subsidence.

Best lift continues to tick N. Keep this coming and it ends up over the S LV by the time it starts snowing

 

Nah keep that centered right over Delaware County please stop the north trend but I am sure it will lol.

Wow.  Front passed through here and temp shot up to 51°.  Compressional heating on a 35 mph west wind.

Wow what a difference from here to there it is currently 32f here.

Did not expect it to be this cold this morning. 23 degrees. 

 

After the light event Saturday, looks like we're down 7 with one time out and they got the ball with less than 5 minutes to go... Or... we're down 3 going into the 9th.

 

GFS still shows the apps runner on the 23rd. CMC has it at the M/D line then cuts north.  Euro says what storm?  

 

Fantasy land has your typical "In like a lion" storm/.

Bottomed out in Media at 21.4f

Does anyone remember this post from page 1 in here? Hope everyone is having a happy Vday blizzard. @Ji 

 

Actually, not bad from that lead it was only off by about 100-150 miles at most, and intensity was like 981 mb leaving Ocean City Maryland.  Not bad at all. Temps are ugly though obviously a much colder look.

Yep, follow the trend.  Oh and again this is not a clipper the is a west coast storm coast to coast.

Hi-Res FV3 looks good

Yea I think as we get into tomorrow runs we are going to see an uptick with more lift and some more temperature gradient stuff just a hunch. Bottom line I think we work ourselves into a 3-6" event over a wider area.

Good point on elevation as it's always important, but I think the main reason areas 10-20 miles and more NW of 95 got a lot more snow with this system was that precip amounts were much greater not that they were at elevation; much of the 95 corridor from Trenton to NYC got stuck in a subsidence zone for 2-3 hours with much less snow falling, as per the radar in real time and the graphic below shows the stark difference of 0.4-0.6" QPF falling from 1 am to 1 pm (precip was over for everyone by then) for the whole 95 corridor from CNJ through NYC vs. 0.8-1.2" QPF for most of NEPA, NWNJ and the Hudson Valley. 

And this difference was even worse from 8:30-11:30 am, which was the prime time for heavy snow and we got only 1.5" during that time, which was less than we got during the one hour from 7:30-8:30 am (1.75" of snow) - I easily would've had 9-10" instead of 6" if I had gotten the precip amounts those NW of me got and I think the same is true for much of the 95 corridor locations from CNJ through NYC/NENJ - we would've kept snowing heavily and accumulating, if only we got the precip, but we didn't. 

Where elevation and temp certainly played a difference was the timing of the changeover to snow, as it was colder, earlier, further NW (not unusual in these setups).  We lost a few tenths of precip to rain before changing at 4:30 am, whereas areas well NW, changed 2-3 hours earlier, getting probably 1-2" more during that time (precip wasn't as heavy).  Also if it was just elevation playing a role, then why did so many locations SE of the fall line (I'm about 8-9 miles SE of it) even get 5-7", as in Middlesex/Somerset counties?  

As an aside, lack of precip intensity is almost certainly why areas from Philly SE through SNJ got very little snow (an inch or so near Philly and little to no snow SE of there.  The precip wasn't heavy enough early on to dynamically cool the column (plus they changed oer to snow even a few hours later than we did) and then by mid-morning, when temps were finally cooler, the precip still wasn't heavy enough.  

ou

100% agree with this here in Media we had 2" an hour from basically 6:30 to 8:00 am then it slacked off from 8:30 to 9:15 or so and those further north and west continued onward with their 2" an hour rates a little disappointing, but honestly it was all rain for us lowlanders 15 hours prior so take what you can get!
