hmm, to chase I think I'm going to need at least 18

if this trends longer duration and 18+ looks doable, and anyone chases this in the M.A i would advise not to stay in ORH as a first choice, it's not a nice city, (at least not the city areas)  and  most of the hotels are no where near the 1k that the airport is ....more like 450-550. 

 

Rte 2 (west of fitchburg) where the elevation rises sharply to 900+ over western 1/3 of the town to say templeton offers a nice 10 mile stretch of hotels for storm chasing. ie westminster, gardner. may not be a bad area.

My reasoning is we are late in the season with cold waters relatively speaking..we do have a high(though not necc. in the ideal position), and a storm that is dynamic,, with crashing heights even to the coast...and a block. Now if we didn't have a block or if any of those other tangibles we missing..then there's no doubt we'd see rain into the deep interior. 

 

But we do have all the necc pieces in place to keep this a mainly colder ptype scenario ..Again..maybe they aren't ideal...but they are there in one degree or another. 

 

i just have a hard time buying the GFS scenario of driving all that rain almost to ORH given what we have in place preceding the storm.

 

maybe I'm crazy..but that's how I see it.

Climo argues for a a BM or just inside track.  I think you will be fine, typical 84 hr gonzo on the bongzo from the GFS.  The airmass is marginal, but dynamics BZ and much warmer waters to our southeast will ensure a track out that way.  0z will tickle that way, 6z make a major move.

 

You will be fine KW........enjoy the snow.

Well I agree that the GFS, even if that track happened, is too warm so yes..I don't agree about rain to ORH for hours. You are right about the other factors, but when we have a borderline situation..a few tweaks here and there mean 4" or 14". IMHO, I think you'll see some good snows. Maybe not 18", but I think they'll be fairly significant.

This will probably juicier than MLK 2010 was...there was a tight gradient right near the pike on that one. Megan was up visiting from NJ at the time and when she drove back she said the snow diappeared rapidly as soon as she hit 84 south from the pike. It was like 10" near me and just north and maybe 3-5" in Sturbridge. The qpf should should be more expansive to the north too.

 

Hmm, the archived BOX PNS from 1/18/10 only had 4.3" at ORH. Bad measurement? I was actually out of town for that event, but remember returning to about 2-3" of hard packed sleet here.

 

 

Not really, that was like 2" at my house down low but only about 5"  up in Shelburne/Colrain.  I recall my disappointment when i thought I was going to have a big ski day out in the woods.

 

 

Oh well, I stand corrected. ALY and BOX PNS statements were pretty paltry from that event across SNE.

Its amazing that we will likely have almost 3 identical sat pics from the last three storms and they all will have gotten to that spot in different ways........climo is strong this time of year, perhaps stronger than at any other time of year. Late Feb into mid March is snow time.

Saturday: Mostly cloudy with a 50 percent chance of snow. Highs in the lower 30s.

Saturday Night And Sunday: Snow. Lows in the upper 20s. Highs in the mid 30s. Chance of snow 90 percent.

Sunday Night: Snow likely. Lows in the lower 20s. Chance of snow 60 percent.

 

Sorry, you live too close to me. The low will go up the NY/NE border and we'll get rain. You watch. ;)

You are a meteorologist. Why wouldn't you look at an 18Z model run? Doesn't mean you swallow it whole, but it is data and I would assume you would want to see it. As for me, I just wait to be told when I should get excited.

The point of a 6 / 18z run of a global model is simply to use up spare compute cycles while we wait for the next round of upper air reports. In practice it just provides another full-resolution ensemble member as the physics are being dominated by very similar initial conditions. Considering the scales of typical background error covariances in the data assimilation system, there is very little novel information on a synoptic scale. (Using the words "data assimilation" is where we queue the ECMWF vs NCEP discussion.)

What a night...next storm might be nudging further north, and currently getting ripped with 2" per hour upslope for the past 2-3 hours.

Trying not to be a weenie but my gut thinks this stays where it is or ticks NW closer to the primary low near the Great Lakes. Plenty of times this season I've given up hope for up here with a strong block but I think this one may have some tickles available.

I had about 7" in that one...ORH airport actually mixed with sleet for a time in that while I didn't 3 miles to the north. I do think the measurement was kind of low though. Don't forget another impulse rode through the next day and dumped another 2-3"...that was probably a separate system though. I sort of lumped the two together

I had 6.7".

The 18Z GFS is fantastic for this area. I'm not sure what the ENY peoplewere worrying about. Maybe ALB itself taints briefly, but mainly snow.

The chances of the 18z GFS verifying when everything else points colder is very very slim. Again..this is the model that gave me 6-12 inches of snow this past weekend from 18 hours out. I think I'm ok lol
