Sad reality. Models did back down some though. 

Yup just saw but it’s still a long duration event of 40-50mph even if the 50-60 don’t verify with the saturated grounds I think there’s gonna be a high impact

Lots going on here the next 24 hours, mesoscale Pres falls alter wind directions-hourly temps radically near the freezing line boundary I84 corridor with icing continuing well into the morning higher terrain there. Presuming it does rise into the upper 30s there this afternoon, ice on branches will drop and melt on you-cars, and helps limit bigger damage from the 50+MPH gusts coming late this afternoon into tomorrow morning.  The rapidly intensifying storm as crosses I84 or I80 (occluding) imo argues for the powerful winds and scattered power outages coming.  Not impossible to have SVR's issue mid-late afternoon I80 southward in the warm sector.  

I'll try to support with reports but after 2PM, probably a no show most of the time with GrandPa duties.

Wantage NJ: 610AM report... estimating radial glaze now about 0.15". its accumulated further top side and now bottom as well on rose bush branches. HARD ice on deck. temp briefly up to 30.2 around 4A but has since dropped to 29.7. fwiw: 350 meters without power near High Point NJ.

Sitting at 31 with freezing rain here near Campbell Hall. It's rough out there with at least .2 accretion on top of the 1.9” of snow I measured last night. Really hoping for that warm air to get in here long enough to get the ice out of the trees before the winds or we'll have a real mess on our hands. Not good out there right now.

Yeah? It better. I have .3" of ice and it's accumulating quickly at 30°. 

I am already above freezing here on the CT Shoreline with just plain rain. So this shows how hard it is these days to get a legit ice storm near the coast. We haven’t had one here since 2011, 2007, and especially 1994.

It's better than staying below freezing but I do t see how the short window of warmth is going to thaw much of this out. .3 ice accretion now. 

Its gonna warm but its looking more and more brief and then a flash freeze tonight. Not good either way with blk ice tonight all over.

Surface winds are draining cold air under an inversion at around 3,000' above sea level. Variable winds will likely continue to around noon or early afternoon.

NYC is in a sort of dead zone between a leading wave now over NE and the primary low in eastern Ohio. By early afternoon the primary will be near Albany and a coastal low will develop over NYC so I would expect 55-60 F air in warm sector to reach central NJ and fog-laden 47 to 50 F saturated air mass trapped between two fronts over lower hudson valley and LI, NYC, expect a thunderstorm or two in the region followed by partial clearing and strong westerly winds by 3 p.m. -- temps will then fall rapidly.

Whats interesting is the forecast temp is in the 50's but currently my dp's are dropping. They were 34/34.. .its currently 34/30f now with a nne wind.

Pressure fall modulations as wind blows into pressure falls if he ardent is not strong. Allows pockets of colder air nearly to to your north-northeast to return for a little while. Still 30.2F here in Wantage.  NAM3K and ECAI 2meters temps seems to have the east fit.

The main roads by me are fine but some of the back roads still have snow/sleet/ice on them. Looks like they were just salted and not plowed off. Hoping they plan on going out this morning and plowing them off because mid-40’s with no sun isn’t enough to completely melt them off later. If they refreeze it’s going to be a disaster tomorrow morning
