East Coast winter storm, February 13th-14th, imminent (Part II)

I will preface this with the caveat that this is still a nice event just inland here in sne, but this epitomizes why I'd rather a mIller B.

1) More room to take an unfavorable track.

2) More time to occlude early.

 

Glad we have a storm, but these are the risks we run with a system born of the s stream.

I know that Steven will have plenty to say, but best case imo is when we have a Miller B with some moisture influx from the south, such as the blizzard last year.

These deals that get fully locked and loaded that far south are risky.

How is the snow gradient drop off looking for PWM? I'm still seeing forecasts of mixed precip for this in Portland

Going to be dicey for us, I think. I'm hoping that we're saved by dynamic cooling (one of the all-time weenie standbys) and the cold SSTs.

There is definitely going to be a warm tongue in CT so Kevin may get close to 32, but for the most part I bet you can bet that Ray-Kevin and points NW are below 32. Maybe Ray gets to 33 for a few hours or something. It may not be a doozy like some models had, but a good front ender for the interior.

Sometimes that happens, sure... Now? I don't think so... Usually you need more a closed slower mover to pull that off. This is moving to fast.

Thanks Tip. Just looked like it when it goes severly neg at BOS latitude. Maybe the change back to snow from sleet is more sw to ne?

Any chance of squeezing a call out of you?

Maybe to climo sites?

My thoughts

ORH 8-11

PVD. 3-5

BDL. 4-6

BOS. 4-6

I think the front end is going to be a huge paste job for some..esp BOS and just inland.

If the GFS verified I would think even out towards ORH it would be 8" of paste, then maybe brief sleet/34F drizzle.

 

edit: I'm more referring to lower elevations E of ORH. I doubt ORH itself gets above freezing.

I am liking the call of 10-14 here still.  Ultimately GFS is too warm and if we stay all snow then I think that range is reasonable...

I'll have some thoughts after I take care of a few things. Gotta feed the weenie in training.

 

Decent numbers I think except maybe like 6-9 at BDL.

nah, still has the look to me of a mix line punching NW, then collapsing rapidly SE when the core of the heights rides over and the winds back aloft.

Someone in N-central Mass over to Springfield and there abouts is going to get annihilated by a thundering meso band in this run.  

 

This definitely should bring some TSSN with it..

 

I'm ~8 miles NE of Springfield. Don't get me excited.

Yeah. There's good lift and snow growth for interior regions but the QPF isn't there. The forecasts I've been seeing are bullish for the interior.

You don't think 1" of qpf modeled (even as much as 1.5 on gfs) would give 15+ in some areas in lucky bands? I agree 10+ won't be common but to say NO totals higher then 10" seems a bit extreme IMO.

Would that also apply for N & W of I-84?

 

More or less..it will prob go to rain there..and perhaps to ORh, but it wouldn't last too long I don't think. There could even be a thin area of marginal icing.

 

My gut tells me though that if the mid-level centers track where they are progged to track, that this will end up a bit colder as we get closer. A lot of these coastal huggers like 12/25/02, 1/3/03, 1/12/96, etc have a very difficult time actually being all rain in the interior.

I wouldn't call my statement extreme...okay so somebody gets 11-12" after good banding, cool, but to say widespread 10-14" is what I consider extreme. 8-10" with isolated 11-12 is more appropriate.

I suspect it wont be until tomorrow night until we might have a better indication of whether or not we deal with mixing issues. I think we (Coastal Cumberland County) happen to be in a spot where a very minor shift in track could make a huge difference in our snowfall totals.
