I'm yet holding at least a little bit of hope for the 2/3 event. IMHO there is really only 1 or two minor preventing at least a bit of snow. Ensambles give out hope.f114.gif

Is there some type of freezing line on this?  Is it that dashed blue line?

The tan line. Dashed blue is -10°C 850mb and the orange is +10

Yea, people seem to be getting hung up on op runs verbatim at long leads. The front is coming. It's pretty much a lock. Will it rain its eyeballs out before the cold and shut off? Sure is possible. Can the boundary drape and slow while impulses ride it? Just happened in Dec.

Trough axis looks like the boundary will take its time pushing off the coast. This is a good thing. If it blasts through there won't be any time for meaningful precip.

I'm interested in the period but already know the risks and flaws.

It's worthy of meaningful disco and not thoughtless hit and runs.

Yes. Thank you and wxmeddler for posting. I was feeling lonely. There's too much disagreement in those ensembles at a relatively short range to think there's a set in stone outcome.

I think I crossed signals with amped. I was speaking about the 6-7 timeframe.

As for thurs, we need the global ops to start tonight and keep going. I'm pretty bearish.

The NAM has the 850 low well north of us at 84 hrs with the 850 temp already above freezing.  It's still pretty bad run. 

yet Wes, it has the vort max well south and diving SE toward the base at 84 hrs.....that make sense the 850 low would be so far north along with the slp?

idk, just asking because I thought the vort max would have been further north

Meddler, look at the 21Z sref ensembles at 850 mb, all the members have the 850 circulation north of us.

Prob nor much chance at getting it underneath us at this stage.

Any thoughts on the arctic front early next week? Looks to be a good precip maker one way or another. Possibly multiple waves running up. I suppose it's our next chance at anything.

only thing I really saw was with the arctic air we could have temps 20-30 below normal
