some other CT webcams (not many out there!)
- Simsbury CT:

this is amusing, what an undeserving storm for so much attention...

You probably have "catpaws" as they are often referred to...rain drops with an ice nucleus that hasn't completely melted yet as it falls through the warmer lower few hundred feet of the atmosphere. Temps in in the hills to your northeast are in the 33-34F range with even probably near freezing in Union...so I'm sure its starting as snow there.

precip shield making steady progess NE now.
i would think N worcester sees flakes within 15 min.
looks like exit 68 in ct. is snowing to me but not clear yet.

Well to be fair the weather has been so boring we haven't had this type of excitement in a while.

Its virga I'm pretty sure...if you zoon into BOX local radar you can see where its reaching...its possible I see some weenie flakes if the leading edge of virga starts to intensify a bit, but its probably going to be until at least 2:45-3am until the good stuff gets over here...but I'll gladly take sooner.

How much of the leading edge do you think is virga? When I looked at the radar then looked outside I was actually quite shocked to already see the ground fairly wet (it had to be precipitating out for at least a few minutes) and there was a mix of rain/flakes/a few sleet pings.

even virga would be more exciting

Hopefully you don't see a great deal of that dry air advect downward...I know eventually the column is going to saturate but if the dry air really begins to dig in that will in turn eat away at the precip. shield and could cut down on the amount of time people see snow

No we def want it in this instance. It would prolong the wintry precip here if we connect up with those dewpoints in Maine...I'm skeptical it happens anyway...but if it does happen, then it would mean a lot longer period of icing.
I do not think we are in any danger of losing much precip to dry air with this current slug moving north. Usually in cold storms where you are closer to the northwest edge of the precip shield is when you worry about advecting too much dry air into the region. In this case, the dry air would act as an evaporational cooling agent to keep the temps from rising as we go along in this storm. That is what happened in the Dec '08 ice storm...ice storms will self-destruct after 4-8 hours (depending on starting temp) if there isn't a physical process to offset the latent heat release from the freezing rain at the surface...that is why without it, you slowly warm until you hit 33F and rain and then stop.

I seriously don't know where I want to live.
It's all going to depend on where my first met job is (if that day ever comes).
I'm not even sure why I'm upset...I was not expecting more than a dusting or a coating of snow at most but I'm still upset...I guess it's like when your favorite team is in a BIG game and you expect them to lose and when they do you're still upset...even tohugh you expected it.

Thanks for the explanation. I would have never thought of it this way.
Speaking of Maine over the past few hours a very nice area of sfc frotongenesis has been developing from Maine and extending southwestward to eastern MA and back towards your area...something that could be of great benefit.
