December 2011 General Discussion/Obs


Chicago Storm

Recommended Posts

Yeah I noticed this with the ensembles compared to the OP GFS both 00z and 06z runs. The Euro looked to be in the middle between the 2 so who knows at this point. To be honest I'd rather not keep looking further down the road because more systems between you and these 'potentials' the more that could/will go wrong.

I won't hold my breath for changeover events, 75% of the time at least for SEMI they end up being crap.

Actually, lately changeover events havent been doing too bad. The last changeover event, November 29/30th, went about as forecast...but the previous one, March 5/6th, dropped much more snow than was forecast.

Good point about potentials can and will go wrong. The models are absolutely HORRIBLE. What I personally look for in the longrange is simply if several models show a storm in a timeframe, makes me think the likelihood of a storm then is pretty good. I am content with them SHOWING a storm, and I know that more or less its time to put it on the backburner until its 48 hours out (and even then major busting can/will occur). I do not even pay attention to temps at all because they change drastically 4 times daily.

Wasn't Detroit's all-time biggest snowstorm a changeover event? :) I'm not comparing this to that, but I'm just saying that they can have wicked potential. Also, biggest snowstorm I've personally been in, in New England, was also a changeover event... rain in the early morning turned into three feet of snow twenty-four hours later. :)

Believe it or not, Detroits biggest snowstorm on record was all snow, in April no less! Though I do agree, some changeover events can work out wonderfully.

Yeah, just looked that up, craziness! Hope to some day see a storm like the January blizzard of '78, with hurricane force winds and everything. :)

Why does Saukville, Tropical, PalmGuy69, and whatever other screen names (i think one time he pretended to be a girl) he's used over the years (for awhile I *think* he was using proxy servers) always make it seem like we all hate winter?

I hate summer. I hate temps above 80F and I hate dewpoints above 65F. I love fall. I love spring. I like temps above 50F, but can easily deal with temps all the way down to 0F. I like winter sun and don't mind snowfall...i do hate when it gets crusty and black and the cloudy for days on end.

Through yesterday, LAF running a smidge above normal with temperatures for December (+0.8º). The next two weeks definitely look warm, so departures should increase. Looking back at my winter guess for LAF (below), I should have gone warmer and less snowy for Dec. Live and learn. At this point, I'd like a do over for January and February too...well January anyway. yikes.png

December 2011

Average temp: 33.5º (+3.0º)

Precipitation: 4.50" (+1.99")

Snowfall: 5.0"

big storm but no cold air to work with.

Yep.

The OP GFS past day 6 is really just weenie fodder, but it's not pretty through the end of the run. Usually it's good for a couple fantasy snowstorms. This run not so much. Regardless, the pattern going forward isn't great. Hopefully we can sneak one in...

Someone mentioned the winter of 1993-94 a couple pages back. I checked the records for Cedar Rapids. December '93 was a bigtime torch for the first 2/3 of the month, but then we had some good cold near Christmas and that was followed by the coldest January of the last 28 years. This December may be quite lackluster, but the weather pattern can change drastically.

Just for giggles and since we're 2 weeks away...what's everyone's prediction for their backyard on Christmas day?

I'm in a bit of a doom and gloom mood today, so I'm going with a high of 48º and partly sunny. We'll revisit later to take out the trash.

Don't know about temps/conditions here. But it'll be green. That you can have in writing.

I'm gonna go with cold and sunny, with highs in the 20s. More than likely we'll have bare ground. We've had several xmas in a row with deep snow cover so I guess I'm okay with it.

Chilly. But yeah, recent Christmas weeks have had snow cover here. Statistically for LAF, the odds are stacked against it. Probably time we had a green one. And like you, I say no big deal really.

Yeah, that winter can serve as a reminder that winter can be backloaded, even with a relatively crappy December. I believe that February offered up four storms in the 6-14" range for S Wisconsin. I'm not sure how bad that Dec was, however.

There's only one that does.

In other news, the 12z GFS looks craptastic. Wake me when it's January.

It's probably exaggerated a bit, but it feels like most of the people that post here (excluding a couple) are on the winter cancel/i hate snow bandwagon.

I don't think so, but I'll admit that I'm on the "I don't want cold if it's not going to snow anyway" bandwagon. I'd rather it be average or above average temps and dry than cold and devoid of snow.
