Yea...nobody even knows I follow a weather board haha...except my girlfriend who recently found out and thinks it is...interesting...

My wife feels the same way. She teases me about it and I ignore it at this point, lol. I followed Weather boards before her (starting with Weather Channel's Winter 2000 board, met her November 2002) so she can tease all she likes will not make a difference to me, lol.

I tell my wife I'm the only guy that spends this much time behind a computer and it's not for porn.

Is that really true, I have heard of that before but I wasn't sure if if was true or not.

Yeah. High clouds out ahead of a storm system, particularly during the baroclinic leaf development stage. Thin high clouds contain ice crystals, which refract sunlight but let some through the cloud deck.

Probably more useful for 18th century mariners. Now that we have radar/satellite and weather models, we don't need to rely on generalized associations.

The high resolution models are probably the best bet right now rather than the globals considering we're near nowcasting mode, though it looks as if the Euro held serve for the most part.

How about them old coastal NJ boundry layers? Does the EC show the low furthur E than say the warmer 12Z NAM and GFS?

My wife is totally ok with it too... until I start telling her that I need to start hugging the European models at around 1:00 AM every night

Yea the real kicker was when she told me she wanted to spend the blizzard with me...we just moved in 2 weeks ago...and i told her it might not be fun for her...she had no idea i would be watching the radar half the time and not sleeping much...she calls it my other girlfriend when i follow a storm and neglect her

This is doubtful. Models appear reasonable as is. Gulf moisture connection to our region appears minimal. Precipitable water is modest. At issue is the intensity of lift, and to a lesser degree its duration. That's how we get more snow out of this. Strong lift, slightly longer duration, good ratios.

With many areas under snow right now reporting heavier rates and higher accumulations why wouldn't this be the case? I understand the lift issue and duration but why wouldn't that additional gulf feed need to be possibly factored in?

Hope so, GFS and NAM but seem to hold temps right around the freezing mark or a hair below for the duration

Looks like the true arctic air finally moved in...dewpoints have dropped significantly over the past couple hours. Now in mid to upper teens for most, with temps right around freezing. Should be good temps tonight for the snowfall...

Back in September/October when the oaks around here started dropping acorns like rocks I told everyone it looks to be a snowy winter. Something I picked up from my Grandmother. Radar wasn't showing anything back then ;)

An early Congrats Jay. Hoping all goes well!

thanks much! :thumbsup: my first... my wife is obviously waiting for just the right storm for me to drive her to the hospital.. I think she might be trying to hold out for the miller A potential next week.... that's my reward for hugging european models.. anyhow.. sorry for being off topic.. i'm in a joking mood today. I'll post the birth announcement in the off topic area when it happens.

Maybe it could set off a line of showers in the gulf states. But I don't think the flow is suitably oriented nor do I think we have enough time to transport gulf moisture to our region. I think the lifting mechanism will operate primarily on the in situ atmospheric moisture with some help from the southerly flow off the Atlantic.

I haven't seen the reports from the midwest, but I suspect the obs are primarily due to lift and temp lining up favorably as opposed to high QPF.

I saw a few reports of 7 to 8" amounts around KC area, seems like a general 3 to 6 in S. IL/IN/KY

edit: a 10" report around Boonville, MO

Hey earthlight...

The 12z NAM looks a little further south with the trof and associated vortmax, no? But the "phase" is still imperfect and a little disjointed. Surface low modestly strong and tucked close to LI. And it hammers New Brunswick!

Maybe relative location is more important than a "perfect phase" on occasion?

:P

Hexagonal plate crystals in high altitude cirrus clouds. They cause sun dogs too.
