This is not a dream period imo. Storms will not come easy nor easily be all snow. It's a good pattern during primetime but it's several levels below a really good winter wx pattern.

EPS is pretty weak for the d10 deal. Majority of solutions that have a storm are too far east. There's a couple good hits but small minority. Safe to say there is little to no ens support for a blocked coastal.

EPS is pretty much unanimous of at least some frozen but as posted above it cut back. There's still an equal mix of a trace/2-4/bigger event like the GFS type solution. Spread indicates that it's too early to jump to any conclusions though.

EPS acts like a hive most of the time at shorter ranges. I'm expecting the ens to support the op. If 0z comes back colder/snowier the EPS will flip as well. OTOH- if the EPS is more consistent with what the GFS is showing I'll toss the op no problem.

I'm not going to sweat 1 run 4+ days out. There's been a notable trend for a colder/souther solution the last few days across the ops and ens. Still enough time for relatively large shifts. No way this tracks under us but there is a path to a real storm. the euro isnt as bad as i thought...it didnt get warmer...it just got lighter on the qpf with the north shift....but 18z saturday is still frozen precip so we just need to adjust the low track. It seems like cold air wont be an issue...i dont think it rains on the euro...it just stops lol Late to the party with a late lunch but WB GEFS has about 80% of its Members with a decent hit for the DMV. Interesting to see what the EPS has to offer. Seems like MLK weekend is bonus snow if it pans out since many, including myself were worried the flip in the pattern could take a little longer to develop. Not saying it can’t be right but the op euro has been over amplified several times lately, including last week when it had that storm cutting to Erie 5 days out. Glad you mentioned this. It's obviously not the big trend everyone wanted to see, but to act like it's a disaster is really odd. I'd call it just a tick in the worse direction, but I like the way the temperatures are trending. Op euro in the coastal camp for the storm next week. Weak surface reflection but this is a cows fart in the right direction away from a big storm!

The wobbles have commenced. Euro broke the trend so we probably know less than we did 30 minutes ago. lol

Like I've said before. Looks like a bread and butter west track/eroding CAD situation. Odds favor some frozen precip. Whether or not it's a memorable or "good" event will depend on how much QPF hits while the column works. Euro is stepping back but it's going to wobble around every 12 hours for a few days. We'll know by Wed if it's going to be a decent snow event or a quick small hit that gets washed away.

Yea, that and the track is a little further north than 0z so could cancel out improvements with the antecedent airmass

Euro ticking colder/stronger with the high leading into the 18th. Very noticeable by hr96. Should be a decent run (famous last words)

@psuhoffman Good analysis on the next window. I do find it comforting that even if that window sucks.... ens guidance looks sweet AF down the line. This is a cold/stormy/active look. Progressive flow but great height pattern in the atlantic to fight off cutters. Of course anytime the NAO is + a cutter can happen but if we aren't going to have a block I'll be perfectly happy with this look through mid March.

What a weenie run... lol

Looks good to me and room to improve...

All ops are converging on a colder start to the storm next weekend. The 0z EPS ticked up quite a bit with # of solutions that have snowfall in SW VA. Now the ops are agreeing with that. We're getting close to locking in some sort of winter wx event now. By this time tomorrow if everything holds or improves it's probably game on here. Warm fronts can be modeled decent 3-4 days in advance so these op runs are at least believable.

That "weird brief warmup" that the gfs op keeps showing is actually supported by the ens now. EPS really picked up on it on the 0z run. Makes sense as the pattern change is a step down process and not like Feb 2015 where winter blew in violently with a single front. Our change to better conditions this time looks more like a multi step process.

I'm not even sure this is an ice sounding. That's not much of a warm nose at all honestly...

This is slowly morphing into a bread and butter west track with 2-6" of snow before ice/dryslot. It's looked like that general setup since d10. Nice to see us better off today than the past couple.

Notable overnight shift with deeper CAD leading in and not just the surface. Always a good sign with a west track when ROA gets snow from a warm front.

diggin these incremental shifts with better confluence/less latitude gain. ICON continues @ 12z.

My guess is if the warm front hits us it will be mostly or all frozen before dry slot and rain. That's our typical climo for this general setup. How much qpf falls is a question. These parts of a storm generally don't drop more than .5 qpf when the low tracks so far west. The juicy cad tracks are up the apps. This one is almost certainly tracking further west than that.

Not going to matter. Storm is slower and weaker this run. We need precip in here as fast as possible. If the storm ,keeps slowing down we'll need incremental improvements north of us

Northern stream creating more confluence on the 0z gfs later this week. Improvement starts early and by hr84 it's obvious

I'm biased. Wxbell is all I use nowadays. All paid services have their pros and cons. Wxbell kills it with variety and great/clean graphics. Has all the euro/eps data you can handle. I've used accuwx (sucks), stormvista (good but antequated), and wxmodels (old style wxbell) Navigation on all paid sites have a learning curve and will frustrate you at first. Wxbell just re-did their interface and I was lost for a minute after having the entire site memorized. All good now. It's month to month billing. Just chip in 25 bucks and have some fun for a month. It's a time suck.

It's a good setup for a good cold shot. D9-10 850s on the eps were -10C. Pretty big departure for that far out in time. If we have a persistent -epo like the ens want us to believe... we could get quite a few cold shots. Quite the turnaround from the last 6 weeks.

I loved the 06 storm. 05-06 would have been a total dud without it. I remember not needing a jacket the next day. I'd have to look it up but my brain remembers 15" in my yard and it was not high ratio snow. Mashed potatoes

After weeks of butt ugly analogs...some interesting ones showing up now...
