Really cool by JB. Like Colonel said, the forum is full of a bunch of new englanders, but usually has good maps and discussion. Also, stumbled on this story from JB.

 

I joined just to get updates and see maps. They seem pretty knowledgeable and less weenies.

Yup, the period between Thursday and the end of the month could actually eclipse February 2010 if it all pans out. Everything seems to be a direct hit for the area right now. Amazing. With March opening on the cold side, we might now be seeing bare ground until at least the start of meteorological Spring.

Creek behind my house is going to be running high and fast after this snow melt.

I'm not worried about details re: storms in the long-range, but the potential is about as good as it can possibly get.  Now we just need everything to fall in line.

Ha! Be careful what you wish for. If it does truly wind up being another "Snowmageddon" period like they typical hypesters are saying (JB and Margusity verbatim), do you really think we'll also be blessed with the ensuing "slow melt" we had back in 2010? Do you have any idea of the flood disaster that was averted that year by nothing more than dumb luck? 2-3 feet worth of heavy, wet snow in this region miraculously melted over a 2-3 week period with almost no rain, sunny to partly cloudy skies, and normal temperatures. If you want my honest opinion, THAT was more notable than the snow itself. If this little Snowmageddon fantasy comes true over the next couple of weeks, I guarantee it's inevitable erasure isn't gonna go nearly as smoothly as it did in 2010, so be careful what you wish for. Unless you enjoy flooding and raw sewage running through the streets, incalculable property damage, etc.

I'm a member there. Never posted, just read. You're right....good maps & discussion, but boy do they argue with each other. It's pretty funny at times.

Still no dice for the storm next week.. We need to see something on the models soon or I think we can just toss that "favorable" period. After that its an a torch again for a few days and we see what if anything can materialize from that windows around the 22-24th.

I think they are starting to come around.  UKIE and German took steps in right direction for 12z.  GFS and CMC took baby steps.

Will there be a next one? The end of the month we torch. 


Go back and read that article that I posted from JB. Not that he is always right, but I like his methodology. Should be another window in Feb and even to begin march. Even with the models not showing it.

I think the rule to live by this winter is "follow the NAM."  While ordinarily that doesn't seem like a great idea, models in the long-range have been even worse than normal.  Don't bother looking beyond that 60 to 84-hour timeframe.  Not a stretch to say it has been a total waste.

Also it makes total sense in this winter to throw away a decent setup.  Not to say that will happen in the end, but it would fit.

Not really sure what I am entirely doing with reanalysis. I figured i would try it out and here was my best shot. If anyone has any suggestions, I'd appreciate them.

 

I figured I would take a look at the ENSO readings since 1950 and find which years were coming out of a weak La Nina and moving towards a neutral phase. I found the years 1965, 1972, 1985, and 1996. I ran a reanalysis on february and march 500 mb geopotential heights. This is the graphic is spat back. 

Decent evidence to not quite give up on the season just yet. According to this, looks like we still have a window of opportunity to score on some decent snows.

March is usually the month we get a quick hitter almost similar to the one we just had. I still wouldn't give up on this week's but gotta see some big changes tonight.

I'm not ready to give up on this week either. A very small change in the positions of energy can make a big difference.

If the energy in Texas can get out ahead of the energy just north of us, i bet they phase and go up closer to the coast instead of OTS. 

One of the analogs of this set up shows a nice snowfall for us. Not saying its likely, but still trying to keep some hope on this week.
