Ended up with 1.92" for the 3-day event (11/11 - 11/13) and it was interesting to watch the temps on Friday start dropping earlier in the morning than I thought would happen.

Looks like there will be an incoming in a few hours, from a line moving at an insane 60 - 70 mph which is out in W. PA at the moment!  Wonder if it might end up being classified as a derecho if it survives the whole way over.  Currently 60 and overcast.

Precip just started here..  Looks like the squall line has consolidated well on radar.  18z NAM has it staying together all the way to the coast.

Also it looks like Mt. Washington, whiteface and the northern green mountain spine are going to pull a couple feet from upslope and lake enhanced snow on the backside of this system.

No lightning here but getting pretty windy with some green transformer flashes off to the west and north.

Yeah I saw some transformers flashing in phoenixville a few miles to my north.  Saw some wild lightning too.  No visible bolts but the entire sky litup a crazy greenish blue and then a minute later the same thing but red/yellow.  Looked like daylight for a second.  Also disappointed in the wind but not complaining after all the tree removal needed from the seperate June 3rd Derecho and microburst events.

Not complaining here either, don't need more wood to cut up right now! Got about .22" of rain and it's calmed down a good bit.
