Sometimes they do and sometimes they don't . Thanks though for being the teacher here. I definitely needed you to teach me.

Why so confrontational? All im saying is that its a good thing to keep in mind. And in general that is what occurs, the surface stays colder and the mid levels warm more. Forgive me for pointing something out. So much for the saying you learn something new everyday.

Looks like a fast mover on radar, that is for sure--I was wondering about forecasts that have this going to late day or early eve...

Yea im not so sure that precip will last that long, though this could be a worse thing for the tri-state as far as icing goes. Precip moves through while colder surface air is still in place.

It is the way you put it. What made you think I did not already know what you were saying? Sure, what I thought would happen did not happen the way I thought it would. It does not mean that I don't understand the workings of the processes.

Point and click fcst low for Central Park is 29F, yet it's 27F right now. I've noted similar differentials w/ other locations in the area. Surface temps right now seem to be underdone by a couple degrees, which could make all the difference at game time.

upton going for a high of 40 tomorrow for my area of southern queens.

Definitely, as i said before, this is such a tricky close forecast that differences like

1) HP +/- a few MB's

2) Track of N/S 5-10 miles

3) 1-2 Degrees +/-

... could make all the difference. Not so much as far is snow/rain goes but as far as icing versus escaping the icing goes.

And so far things are leaning(at least for this area) towards number 1 being a few MB stronger and 3 being a few degrees cooler

compared to RUC and NAM, they look right on track. both the 12 and 18z NAM text data has KNYC bottoming out at 25F around 10pm

Wasnt trying to call you out, i was saying id rather have that then the ice at this point. Heck i made a call that NYC would surely not see over 6" from the last storm and basically assured my job against it..... look how that turned out. Sometimes we win sometimes we lose, thus is the fun in meteorology. Apologies.

Same here. I did not realize that last incident was you. Ouch. Yes, this one did not turn out the way I thought it would, but really not that far off. The NWS pretty much busted in this area really bad today too, so it is not just us.

precip will likely move in quick and be done quick. I could see some parts of the tri-state area done with steady precip by late morning

Hmmm.....I was wondering about this, note the 2 highlighted statements.

SFC TEMPS WILL BE SLOW TO WARM LATE TONIGHT...AND AS PRECIP MOVES

INTO THE REGION...WILL GENERALLY EXPECT FREEZING RAIN WITH SOME

SLEET POSSIBLE. H8 TEMPS WILL WARM TO 0-2C ACROSS THE INTERIOR AND

TO 2-4C FOR THE SOUTH. WITH SFC TEMPS IN THE INTERIOR NOT WARMING

MUCH ABOVE THE UPPER 20S...THIS SETS UP FOR A PROLONGED FREEZING

RAIN EVENT. ICE STORM WARNING REMAINS UP FOR THESE AREAS...AS UP

TO 1/2" ICE ACCUMULATION IS EXPECTED. FOR THE REST OF THE AREA...

GENERALLY INCLUDING LONG ISLAND...NYC...COASTAL PORTIONS OF NE NJ

AND SOUTHERN AND EASTERN CT...ICE ACCUMULATIONS OF UP TO 1/4" ARE

EXPECTED BEFORE WINDS SHIFT TO THE EAST...AND ALLOW SFC TEMPS TO

WARM INTO THE MID AND UPPER 30S...POSSIBLY APPROACHING 40 IN SOME

SPOTS ON LONG ISLAND. SLEET AND FREEZING RAIN LOOK TO CHANGE TO

PLAIN RAIN WED MORNING ACROSS NYC/COASTAL NJ/LONG ISLAND AROUND

9AM...AND THEN AROUND NOON FOR SOUTHERN AND EASTERN CT. WITH SUCH

WARM AIR ALOFT...NOT EXPECTING SNOW DURING THE DAY...SO WILL

REMOVE FROM FCST. WITH PWATS APPROACHING 1 INCH IN THE

REGION...COULD EVEN EXPERIENCE SOME HEAVY RAIN AT TIMES DURING THE

DAY WED.

This may have been already posted or stated so my appologies.................here's what Mt. Holly is thinking..................Nasty if it verifies here in the NW Surburbs.

We're down to 23F already here in Parsippany,NJ.....................temps projected to go down to the upper teens to low 20s. recipe for some major icing here.

...ICE STORM WARNING IN EFFECT UNTIL 6 PM EST WEDNESDAY... ...THIS REPLACES THE WINTER STORM WARNING...

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS ISSUED AN ICE STORM WARNING...WHICH IS IN EFFECT UNTIL 6 PM EST WEDNESDAY. THE WINTER STORM WARNING HAS BEEN CANCELLED.

* AREAS AFFECTED: NORTHEAST PENNSYLVANIA AND NORTHWEST NEW JERSEY.

* PRECIPITATION TYPES: HEAVY FREEZING RAIN. THERE IS A CHANCE THAT SLEET OCCURS OVERNIGHT...ESPECIALLY IN THE POCONOS AND SUSSEX COUNTY NEW JERSEY.

* ACCUMULATIONS: GLAZE ACCUMULATIONS OF ONE HALF TO THREE QUARTERS OF AN INCH ARE EXPECTED BY 10 AM WEDNESDAY. IF SLEET OCCURS... GLAZE ACCUMULATION WOULD BE LESS BUT SLEET COULD ACCUMULATE ONE HALF INCH.

* TEMPERATURES WILL BE IN THE UPPER TEENS AND 20S THROUGHOUT THIS STORM

Has anyone felt their snowpack this afternoon? You need a light hammer to break through it. I broke off the top layer and the ice is about 0.2 inches thick. Not bad at all. I also placed a large piece of cardboard on my windshield so I don't have to sit there with the ice scraper tomorrow morning. arrowheadsmiley.png

current temperature is 25 degrees in Pompton Plains. Everything was covered in ice when I got home from work. Headed down to Newark now to watch my Devils play. I'm hoping the precip holds off till at least 11pm. Be safe everyone, expecting a catastrophic ice storm of 0.5" + here in Morris County.

There will certainly be melting and re-freezing but not sure if we'll get any real flash freeze. Temps drop below freezing by early evening but its not sudden or a sharp drop. The worst I remember is March of '05 where it was raining in the morning with temps in the upper 30s and by evening we were in the teens and everything turned instantly to ice.

Maybe a little flash freezing? A lot of puddles will likely rapidly refreeze as cold air quickly plunges in after things warm up during the day.
