it's almost FEB and the most I've had imby is 1.2"

at first, these little events were good enough while I waited for something decent

but I'm at a point in the season where these kind of events just don't excite me anymore, that's all

I'm getting the feeling that unless we get a late season fluke (ala 3/1/09) we will be shutout this year and I'm tired of it already

yes, I'm mentally getting ready for spring I guess, especially after yesterday

 

Welcome to the dark (and real) side.   I'm all for optimism (fake and otherwise), but let's not kid ourselves.    Anybody that keeps saying they are happy and excited with a 1 or 2 inch clipper likely isn't telling the truth.    Yeah, at first, it was great.   But a car topper isn't going to cut it.  We're at 3rd and long here.  February is approaching...first half is probably f**ked.   That leaves us 2 weeks and then March.    We're all worried, no matter what anybody posts here.   I'm vested here...I don't care who gets pissed...I'm keepin it real.

Agreed.  These piddly events are ok in Dec through mid-Jan, but they are not going to work in Feb.  Unless it happens overnight, weak precip rates can't overcome the sun-angle unless the air is really cold, and that kind of air was hard enough to come by for 3 days in January.  I watched this happen Saturday as I saw 6+ hours of snow melt while the temp was 28 - 31 degrees.

I know we have squally weather on the way and everyone is staring at a medium range filled with clippers; but, you can see the increase in the southern stream's influence starting next week on the data. While this isn't an overly cold pattern, the possibility is heightened for a front to stall in the Mid Atlantic as the STJ overrides the boundary, bringing waves of low pressure and precip. Temperatures will not look overly impressive and may not be sufficient for wintry weather until close range.

 

The risk is highest between Feb 8-15. The bombing clippers will help keep some confluence in southern Canada and bring periodic -NAO_east responses.

When you and Mitch start complaining like the weenies you know we are in real trouble.

It's evolving.  I actually thought it looked pretty good heading into the end of the run.

there have been a lot of NAM runs "at the end" this year that have not looked bad, but they have all generally failed to produce the magnitude that they showed

which, by the way, is a hallmark for lousy winters (consistently great endings to model runs with nothing of substance come verification time)

if the CFS2 was going to be right, it was going to be wrt precip

it's done unfortunately well in that regard for JAN and its FEB forecast is no better

in the meantime, enjoy the first "spring-like" cold front of the upcoming season

here is some precip

it is an awful run, but it is just a run....the bright side is we have <6 weeks to suffer if nothing materializes and then we can forget about this winter....though you can always muster something in the 3/16-4/7 period

 

ji is not getting april snow

Just a heads up: The precip amounts with the clipper may seem meager but check your ratios. I was modeled to have QPF that low too last week and ended up with nearly 2 inches. Many people in our area saw ratios exceeding 20:1 or so. Now, obviously this isn't the same kind of cold but it is important to check soundings and see how cold it is in the mid levels / is there any frontogensis.

 

There is nothing wrong with the GFS. Plenty of southern stream action and storminess with a revolving polar vortex in Canada. It will loop around through mid Feb at least, dropping south toward Hudson/Quebec and then rising north with NW Atlantic systems. When the PV comes down to its further south points will be when we see our snow chances (the first loop down is all clipper action obviously. the second loop down comes toward 2/10). Inland runners are obviously going to happen with a pattern like this but so will stalled boundaries to our south with waves of low pressure. It's not a bad as it seems.

I've completely stopped getting hooked into the lr this year. I'm sure you have too. One easy takeaway from this year is no stj + neutral nao = almost no lr skill. 

 

December was different because of the -pna and crap epo. That was stable. Nothing else has been. Like HM just said, at least every decent inland storm comes a period of cold. It doesn't takes miracles to get the air in place. It just won't stick around long enough without some sort of stable feature to keep it here. I will laugh when the nao pegs neg in April and we sit in days and days of 50 degree drizzle.

If a sloppy wet snowstorm was being modeled ~ 2/10 after a couple of crappy clippers and inland runners, there would still be complaints about the lack of NAO and how this winter has gone. I told the MA to punt when we should earlier in the winter but I can't say to punt yet with this period coming up. If I'm wrong, I'm wrong but I really do think there is something to this period coming up.

HM I also like the 2/25-3/7 period. You looked into that at all? I did well with my 1/25-1/30 prediction back on the 12th.
