December 2013 General Discussion

[snowlover2]

The last month of the year is almost upon us. How cold and snowy will it be? Who will see a white Christmas? Discuss.

[wisconsinwx]

I think it will be important to cash in on the first two weeks, because during that time it is pretty clear there will be a SE Ridge of some magnitude.  Beyond that, it looks quite possible the NAO goes negative, and perhaps things will trend toward colder and drier?  Just my preliminary thoughts.

[Gilbertfly]

2013......the year of the Christmas Blockbuster Barn Burner Blizzard...get your tickets now

[Geos]

Yeah first two weeks looks active. I think the chance for an area wide white Christmas is really good this year. Snow in the Great Lakes first and then a shift to the OV towards the holiday more so.

[snowstormcanuck]

That -EPO/-PNA is creating an odd upper pattern heading into December. Big trough out west but the warming back home is kind of muted by the EPO quashing the SE ridge.

Maybe off topic but does anything have a good winter reflectivity palette they can share for GRLevel3?

Thanks a bunch, pretty much exactly what I hoping for.

6-10 day CPC outlook. Cold and wet for this sub forum.

 

[michsnowfreak]

Everyone seems to be talking/hyping a pattern eerily similar to December 2008.

 

Great December here.

That was an awesome December here! 70 inches in a month. Unfortunately. I wasn't here to witness it...I moved here the next winter.

Scroll to pages 9 and after to check out all the "footer" events we had!

That was an awesome month here too! 34.1" here.

I do that or December of 2000 over again.

[cyclone77]

Cold air continues to slowly build over the arctic as we move on into December.  Some -30s showing up in Alaska tonight. 

 

 

[michsnowfreak]

Was downtown Detroit for dinner tonight, and they are all decked out for Christmas now, so we decided to walk around. Really nice holiday atmosphere. It was interesting that with temps in the mid-30s during the evening, it didnt even feel cold. Guess Ma Nature has really prepped me for winter by a cold November

Starting off December on a pretty seasonable note; 28° with clear skies, frosty.

 

Nice pictures Snow Freak! You've got a nice camera for taking night pictures. Like those curtain lights on the building faces - hard to find those.

Thanks . It was pretty bright with all the Christmas lights, so the main key is steady hand and no flash. If you are in Chicago during the season, I assume they do some nice decorating too, try it out!The curtain lights go all the way down Woodward Ave from Campus Martias (the huge skating rink) to almost Comerica Park. They look really cool in person, the pics dont do it justice.

Yeah man amazing pictures. Cant wait for Christmas and New years. Best time of the year. And hopefully we get some snow around it so we can discuss about it and have a white Christmas

They do something similar here in Toronto as well. After a nice family dinner I often go to downtown on christmas eve.

[IWXwx]

Happy met winter everyone!

 

Starting out at an unwinterlike 37° at 5 am.

[DAFF]

Those pictures of downtown Detroit remind me of Disney from last year. Great to see people in the downtown core enjoying the festivities. With the recent cold snap these normal temps feel balmy  Today I'm heading to the shop to take advantage of the warmth and get everything buttened up for the winter weather ahead.

[michsnowfreak]

Todays the 39th anniversary of Detroits 2nd biggest snowstorm on record officially. The immediate DTW area was hit with 19-20" of wet snow December 1-2, 1974, the official total 19.3" at DTW, many 20" reports in nearby areas. Here are the hourly obs for the storm at DTW. Thunderstorm was reported at 7:10pm

Great pictures snowfreak. The weather is miserable in Toronto this morning. Light rain with temperatures in the mid thirties. I can't stand rain in the winter.

 

I'm hoping there'll still be a charge of cold air this weekend, while also hoping the driving conditions are good between Toronto and Rochester, New York on the 7th and 8th. I'm going to the Genessee Country Village for their "Yuletide in the country".

[SpartyOn]

Not very winterish outside today. Feels more like a early spring day.

[Geos]

Temperature here is a degree below average. Starting to cloud up now. N winds will keep the temperature in check today, no upper 40s with a flow like that.

[Central Illinois]

Pretty nice outside almost hitting 50 already

[Geos]

Temperature stalled out here with some sun, but not a lot. 38°

Pretty typical for the first of December.

[Hoosier]

We're actually not far off from having a severe threat on the 3rd-4th.  Achieving quality low level moisture return in time seems like it's going to be a problem so I don't think anything is really going to come of it but a little more and things might've been different.

[hawkeye_wx]

Temp is overperforming again today.  Forecast was 40, but we're at 45.

[Thundersnow12]

18z NAM gets temps to 60 up to DVN on Tues.

Big contrast over N IL with the back door cold front parked over the area.
