I was thinking the same thing.  The Maine storm was really dense--and more of it.  We'll be fine there because of that.

My pack is pretty icy, so may survive.

My town uses the liquid brine stuff on the main roads, but then the greenish colored salt mix on our side roads.     They will probably be plowing during the rain anyway, digging up our wrecked road

Same here on the brine, They usually pre treat a day or two before an event.

Nuisance to moderately severe urban ponding is very likely to develop by mid-day Monday as temperatures rapidly rise into low 50s with this expected rain, in particular s CT could see near total melt of existing snow pack but any large snowbanks created by plow operations will survive (partially) and acr as dams for rapidly accumulating meltwater. Some drains will be blocked which will prolong the nuisance. This will be followed by a rapid freeze Monday night and any slushy cover will become solid icy glop. Despite differences in lat-long we have had this same cycle here about three days ahead, first the 4-8 inch snow cover, then the rain and the flash freeze. We lost most of our snow pack even with a peak temp of 40 F in the rainfall. It then fell to 15 F and everything has frozen solid, our partial snow cover looks like snow but is frozen solid, any slush not removed from parking lots or driveways is now a solid frozen mess. Obviously further north into n CT and w/c MA there will be less total snowmelt but there will probably be some urban ponding anyway and a similar cycle will develop without full removal of snow on ground.

Have rebounded nicely up to 36F down here, icing issue canceled?

[dendrite]

Even 32° here with full sun. Nice afternoon. 

[Lava Rock]

39f. Relative torch.

Only 19F at MVL in sun.

Its 37-39F at our two sensors top of FourRunner Quad and Gondola.

20 degree difference is impressive during sunshine.

37 here. Ground is warming nicely. Snow melting on the sidewalks

28.6 warmed up quick today. Looks meh for ice

Not sure, @CT Rain posted not too long ago and sees potential still overnight;you have a better shot than most

Meh on qpf.. can't get ice without that 

[VivaManchVegas]

We rebounded to 38 from a low of 6.  Impressive. Milky sky.  Revised GYX forecast had us topping out at 36.  Sundown temperature of 32.  Calling for about 0.4" of freezing rain followed by 37 degrees and 0.25" of rain, hopefully enough to minimize the power outage threat before the winds move in tomorrow night.  

[WxWatcher007]

Ice canceled here by BTV. Went from .35 expected to .08 lol. 

[Go Kart Mozart]

Paging Wiz...what do the post-storm winds look like?

[wxeyeNH]

I just noticed that the NWS upgraded my area to a Winter Storm Warning.  I know Dendy was not overly impressed yesterday and Tip for several reasons was not impressed earlier.  It is currently 34/14F.   Any changes in thoughts or basically just some slippery roads and some glazing but not enough for power concerns etc.

29 here under cloudy skies.

Color me shocked.

One of the shortest lived storm threads evah.

They bit on the HREF icing. I’m still taking the under.

No need to...  
the cold you are referring is particularly low level, and not substantive in the mass loading into this system's preceding environment.  The "real" synoptic cold is still low ... 22-ish with DPs of 10 or so, but with such limited +PP ( positive pressure pattern (high pressure) ) situated N, a 20 to 25 kt sustained 925 mb low arriving flow will change the setting very quickly.   
These metrical limitations on this system are not going anywhere.   They are a predicament/detriment to this system's ability to maintain froze or freezing profiles.    
Lemme tell you something ... in late January 1994, we awoke one faithful morning to Winter Weather Advisory headlines in place, a temperature of 9 F on the weather lab's tele, and periodic flurries/grits coming down in the dim blue light of dawn throughout the Merrimack Valley.  Deep winter was in place.   By noon, sleet pellets had broken out, there was a south breeze, and the temperature had risen to 23 or so...  By 3 pm, it was 31 F with steady freezing rain.  By 6pm, it was 53 F with wildly swaying tree tops, and ice fog rolling off the snow pack and piles.  By 9pm, it was 61 F with 55 mph gusts. Student around the campus had spilled into the commons and down town streets of Lowell's pubs, in short sleeve shirts that seemed to finalize a defiant mockery of winter...  
9 to 61, in 12 hours.   
All because a cutter went through BUF-ish, and had no antecedent +PP to protect from the arriving WCB ( warm conveyor belt ) -related wind field.  
Now, this situation doesn't have a 65 kt 920 mb jet core fire hosing at it...no.  But, the 40 kts with no leading surface high is going to still reverse the tables and do it probably at a speed that comes to some surprise to people, even in the valleys.

GYX going aggressive. Might be a few fender benders on 93 tomorrow morning.

[Damage In Tolland]

Now that’s  a lotta damage

lol…that’s like 70% of the euro qpf in the Merrimack Valley. We’re not getting a half inch of accretion

Down to 28 off a high of 29.

Warmed up to 37 Here and got some melting on the driveway.
