snow maps are going to make some people run naked. I can't tell for sure but the first half of the precip is all snow at least. LOL streak over!

 

I think I would prefer this run over a miller b. 

 

im giving this run a 1% chance of verifying

we got a 5 inch dump from a similar chicago storm a few years ago

 

better to go that far west than closer probably. except precip might be overdone and im not sure why we stay that cold. the high is nice but it's pretty far north and shifts east with the precip.

That high?

I'm willing to bet my tag on this. If we get a major (6+) on the 22nd, I will swap tags with Ji for 24 hours.

Now let's get the fine details of this deal. This would be an all time great, i would probably stay on the board for 24 hours straight. So if where you and Ian live gets 6" than Ji will be an Admin for a day?. Of course it has to be your house not DCA.

2"

 

Usually in the crappy winters we eek out a fluke at some point or at least one 3" event...which may not make it a fluke I guess

 

March 99

Feb 06 (though we did have some good snow 11/23 - 12/15)

March 09

Feb 95

January 02

December 07

 

It is actually pretty hard for us to get <4".....which has kind of kept me hopeful...obviously peristence is a b**ch...68-69, one of my analogs, is actually not bad in some ways....same thing that year....2 KU's for 40N in FEB and we had 2" going into March where we then got a couple storms and ended up with 9"...There are 4 things still keeping me hopeful

 

1) Pattern is not that hostile going forward

2) Climo says it is really hard to get 2" seasonal

3) Analogs suggested a decent end of season

4) Wishcasting, figuring if I am delusional it is only for another month and then I can recover

I would also imagine that climo says it is really hard to get 2" of snow, two winters in a row.  Next week seems like a good window for something, but given how things have gone this winter, it's hard to be optimistic.

We have to start paying attention to the GGEM I suppose... 4DVAR and better resolution. 

 

What about the NAVGEM NOVAforecaster was talking about? It's a real thing, when does the switch occur?

models are always being upgraded and tweaked, so are the US models.  NAM is due for an upgrade soon, not sure about the GFS.  Either way, until the upgrades go operational and we have verification scores to show it, I am skeptical of any "major leap" in accuracy from these marginal models.

there are a number of ways to spin it to work for or against us...I'd be more worried we were turning into Richmond if I didnt get 68" of snow 3 years ago....

most of us don't use them properly anyway

I am far from an expert, but it just seems like recently we get very few of the small storms that we used to get here all the time when i was a kid. The good news is it seems like the larger and KU storms will be much more frequent than in the past.

You would have to think that that we're due for a good winter in at least one of the next two or three winters.  And by good, I mean average (which would be good after last winter and this).  It's interesting that we've had two abysmal winters in a row, but with fairly different patterns.  This year we haven't had the persistent GOA low (and Nina) which in part gave us the incredibly warm winter and spring last year.  We've had a few windows with colder air this winter, that we didn't have last.

sometimes the upgrades make it harder for me to use them as an effective tool for a while.  No matter how good, none of them are going to be perfect.  After a while I can get a feel for how the various guidance handles different situations and then how to correct for those issues.  When they go and "correct" things, it can throw off my feel for how the model is behaving.  I am sure the pro mets are able to stay current on all the changes and bias modifications but sometimes I am not, and thus learn from trial and error.  Consistency is just as important to me as accuracy.  If a model is wrong, but is always wrong in the same general way, it can be a useful tool.  If it is inconsistent in how it is wrong, then it can be darn near useless.
