"Quite honestly if you doubt the LRC just look at 500 mb charts from 37 days ago and loop them all together... do some research on your own. I posted a good comparison of 37 days, 74 days ago, 111 days ago, and even an image of May '09 next to last post on last night's blog entry. There are just too many things going on up there that match up to be totally discounted as non existant. Signature storms show up more visibly to the eye, but even general air mass propagation shows up as well. True - it would make it difficult to forecast in advance - but given the same scenario and if the LRC is in fact 37 days this year, I can - and be quoted on this - say there is a 95% chance that there will be a major storm system over northern New Mexico and southern Colorado on the weekend of December 4-5-6 and as long as it takes a similar track to the lows 37, 74, and 111 days ago (with stronger jet factored in) - Kansas City has a good shot at at least 2-4" of snow on the 6th and 7th of December.

If I'm wrong, I'm wrong. If I'm right, then I'm right because there is a recognizable pattern with lows dropping in and digging - further south as the jet stream gets stronger - but in the same general north-south juxtaposition.

Just in case you don't want to dig for them here they are:

Yesterday: http://tinyurl.com/ygexduq
37 days before yesterday (1 cycle): http://tinyurl.com/ykmp7be
74 days before yesterday (2 cycles): http://tinyurl.com/yhhkj5l
111 days before yesterday (3 cycles): http://tinyurl.com/ylbo3tb

May 31st there was a Surface low in that very familiar place but no upper level low: http://tinyurl.com/yfzqfyo

You be the judge. I'm getting all these images from http://weather.unisys.com/archive/eta_init/ and the more and more I loop them, the more and more it looks like a train moving further south over time with the strengthening and weakening phases fluctuating position based upon the strength of the jet stream at the time of year."

So what exactly are you trying to say, Flake? I look at the pictures, and basically get nothing..meaning I don't quite understand them.
