March Medium-Long Range Discotheque

I'm still not sold on a storm at this range (just too far out), but all I see is wave after wave of arctic cold and low after low tracking up the coast or down out of Canada on the GFS. Just need one pair of those to coincide and we get a storm. Two of them look promising this morning for snow, around 174 hrs (glancing blow) and 300 hrs are the big ones. A few clippers are in there too, mainly in the 180 to 300 hour period.

 

So when will spring start? We're looking 3 weeks into March and still no sign of warm weather.

I'm all in for cold and snow but as I see it we had our season finale on Monday. I'll even take a 93 rerun next week. However past next week it's gotta be done. Nothing sucks more than a frigid opening day at Oriole Park. The month between winter and spring is the worst. At least the month between summer and fall has football.

Not a model expert by any means, but it appears the storm isn't indicated on this GFS run. New England gets smoked though.

It all depends on the track of the vort/slp. Euro ensembles are mixed. If the vort/slp tracks below us through southern wva/va then we would get some snow. Very much unresolved. Op runs of the globals will continue to flip around for days.

Yeah, GFS is definitely flipping around.  This run, we're on the bad side of the boundary and the storm is a lot sooner.

though pretty much garbage in prior winters, the CFS2 has done well this winter, and really well since JAN

that said, the MAR precip map from the CFS2 is below and that, along with the modeling history of Monday's event suggests to me the storm will be south of what the GFS shows today

We have a fair chance here. How much is anyone's guess. Trends over the last month have been to start north and end south on guidance. I have no reason to believe that might not happen again.

I don't like the euro's multi low depiction. We aren't going to do well there. A simple vort passing south with slp out in front can do it. It would bring down sufficient cold with it even if it's rain/mix to snow. I'm watching it but with no real clarity about strength/placement/timing/evolution it's pretty easy to be indifferent now. Maybe we'll start to see some sort of consensus this weekend. Then tracking run over run changes becomes a more meaningful exercise.

Anecdotally....it seems to want to find a way to snow around here nowadays.

I sorta agree with Mitch. Trends would favor a more southern track. But even with that, if a convoluted strung out evolution happens we can easily be all rain. We need a consolidated punch.

I'm interested in what the euro analogs show later today. Hopefully matt posts them.

12z GEFS is just interesting enough to make me think maybe... just maybe...

 

138 -- 1001 L N KY

144 -- 1000 L C WV

150 -- 998 L C VA (RIC area)

156 -- 996 E of ACY ~100 miles or so

162 -- 994 L by 40/70 benchmark or so

 

 

138 and 144 DCA 850s are +2... ~+1 at 150... and ~-4 at 156... so rain to snow?

although it would be nice to maintain that trend, the 0Z ensembles will be meaningless in 3 hrs

I don't think so.  12-hours isn't that long a time period when you're talking 6-8 days and having ensembles from simulations initialized at different times adds value and lessens noise.

the fact that it's out 6-8 days gives it little weight in the first place and so every run closer to the potential event becomes better than the prior one imho

It's a pretty big storm with some hits of redevelopment at 168, but by then it's too late for us.   Probably gonna smack NE good though.

 

EDIT:  Just saw the link (I was only out to 156 before)...im at 180 now..that puppy destroy upstate NY, Maine and probably SNE
