March DISCO/OBS: Please End It

You guys didn't ask me but re the operational majors.

The GFS typically lags behind the others during the winter into spring seasonal change.   It's a subtle issue with that guidance ( not very obvious ...) but it tends too end up with a surplus of cold heights out in time.  I've even mused at times that it seemed to do so at the same rate the complexion of the hemisphere should be gaining heights from solar forcing and normal migration.  It's like its bias almost proportionately offsets spring's advance.  

That's why if anyone's bothered to remember how the model has behaved during this time of year, over the years ..., you might recall that it tends to end up with longer ranges that look like winter synoptics at oddly late times.  Say you are looking at a May 8th LR outlook from April 25th, and it's ending up with blue dipping lines S of Chicago with turbo jet strengths... Meanwhile, the other guidance are already hinting at Sonoran/SW heat releases.  

Anyway, there's a pretty obvious multi-guidance ens sourced   -WPO/+PNA  ( EPO's a little flat... but whatever ) between the 23rdish and the 30thlike ...  Uh, not a good look for spring/warm enthusiasts.  So both these colder correlations, and the GFS doing so anyway ... are concurrently true.

There's a lot of reasons to suspect that we won't max as cold as the correlations would fit, however - rabbit hole.   You know ...we just went through almost 10 days of -NAO, much of which was even west based, yet put up positive departures for the period in March.    Correlations have been getting stressed over the years ...  That look, -WPO/+PNA showed up during this winter on a couple of occasions.  Yet, only unrelenting poor performance drove many of us to divorce our ambitions for the seasonal intercourse so to speak, so now in spring? It gets even uglier.   We'll see, but to me the GFS should be suspect when given any excuse to validate it's masturbatory habits with the N stream.  While at the same time ... -WPO/+PNA ... could still perform when we least expect it to do so, thus ... abasing the veracity of this clad reasoning in lieu of enabling fuckery.

This always happens as we get into April.

More times than not, yes.  And this is the problem- especially in NE, we get the first few days of 60-65 in March, and everybody is all giddy with spring warmth fever, and then we settle into the doldrums of overcast and 46 with a raw breeze, and sprinkles/drizzle, for weeks on end as March wears on. And then April continues the crap; with a nice day or maybe two mixed in if we’re fortunate.  But it’s mostly crap.  That’s why I don’t understand the rush to that kind of crap. 
 

 Sure we have nice springs sometimes too, but get ready for the crap this go around it seems.

Frankly ... I like the UKMET's look for Friday the best.  It really  this should do jack shit.   I could see it smelling like snow cold mist as it ends more than actual snow in the air.  

It's a progressive system in a pattern foot that has never favored anything deepening/developing  in time since 2015 so -

Underrated event began 12 years ago this evening. One hell of a SWFE. Had about 10" in Dorchester..pretty sure Ray had about a foot.

The St Paddy 2007 event was nice...11" of paste in Wilmington and 13" of powder on the other side of the CF up at UML.

I don't think its anyone rushing to that crap, but I do agree that these great days early in the season can sometimes make us forget how shitty spring can and usually is. but I don't think its anyone rushing to this...its more about knowing there will be these type of days mixed in and trying to take advantage of them. It's also a sign that, yes while we have crap, we are going through the tunnel and be out of the crap soon enough.

Interesting, my average here is only 4” less than you but my sample size is only 12 years. I am 15” behind you season to date but I can’t remember the storms that we missed that you got? That’s a decent variation for not a ton of latitude/climo gain. I was up at saddleback this weekend and the drive home through weld, Peru, Hartford was interesting, more pack hanging on in those hills as of yesterday than rangeley area. Seems like your area may have been the sweet spot in this unremarkable season for interior Maine.

Things started off great, with 8" Thanksgiving night and 9.3" on Dec 5, the two biggest snows of the season.  We had recorded 24" by Dec 10.  From then on, it has been a bunch of itty-bitties, other than the Feb 16-17 event which matched the T-Day's 8".  We've had only 2 warned storms, tied with 2015-16 for the fewest; median WSW is 6. (Dec 5 was an overperformer, forecast was 3-6.)

Midlevel warmth spoiled it up here.  Started with 7" powder then 3" IP from 1.1" LE at temp in upper teens, capped with some ZR.  Total LE was 1.92", an 18-20" potential turned to 7.5".

Some kept saying they wanted out in late February…that’s rushing.  And you rush to more lousy weather than good weather most of the time.  But yes…this is the tunnel that we have to go through here…we know this.  


But being out of the crap soon enough…ya it’s a long tunnel from here(3/18) if the weather is lousy.???

No doubt that tunnel can be long. I mean we've certainly had some terrible weather well past Memorial Day. It's a crap shoot around here.

It's funny he refers to it as a "tunnel"  because that's precisely what gets stuffed by it

 right up the tunnel !
