snow_wizard Posted January 22, 2014 Report Share Posted January 22, 2014 I just ran some composites for January 500mb anomalies for North America and the NE Pacific and the results ares stunning. It's incredible how certain anomaly patterns can lock in for decades and then drastically change to something different. To have such extreme anomaly signatures show up over such long time periods is pretty amazing. Anyway this clearly shows why January has sucked balls since 1980. The composite for 2007-13 is certainly an improvement from 1981-2006, but still a long way to go. The first two maps are from the cold phase. One is 1948-1980 and the other 1949-57. The next one is from the warm phase 1981-2006. The last map is from 2007-13. Obviously we need the positive center to move NW for things to get good. Quote Death To Warm Anomalies!

Dan the Weatherman Posted January 22, 2014 Report Share Posted January 22, 2014 I now see why 5 out of the last 7 Januaries (going on 6 out of 8 this year) were so horrible for Socal. However, last year going into this year has had the driest weather overall. Quote Link to comment Share on other sites More sharing options...

However, last year going into this year has had the driest weather overall. No question out of the 4 maps the most recent is the worst for you. I certainly hope we see that positive center jump NW over the next few years. Quote Death To Warm Anomalies!

BLI snowman Posted January 22, 2014 Report Share Posted January 22, 2014 We haven't had a -PNA January since 2008 http://www.cpc.ncep.noaa.gov/products/precip/CWlink/pna/norm.pna.monthly.b5001.current.ascii.table Last January PNA of -1.00 or lower was in 1972. In that same timeframe, we've had 10 Januaries with a PNA of 1.00 or higher. Positive PNA has probably come to dominate January more than any other month. It's kind of crazy. One of these years the atmosphere will probably just out a January with an extreme reversal of this decades-long pattern. Just a question of when.

TT-SEA Posted January 22, 2014 Report Share Posted January 22, 2014 Just a thought after looking at the evolution above... it could be another 50 years before it goes back to the previous regime. Or more. If that is the case... not sure it will matter to any of us unless you are planning to live forever.

Brennan Posted January 23, 2014 Report Share Posted January 23, 2014 I don’t understand why This thread is an example of one that we should put in the National discussion area. I will move it tomorrow.Why is this stuff so sensitive? I don’t understand why topics in this forum have to be so specified to PNW weather. Lets open it up a bit. This is a great thread for this section of the forum. Quote Link to comment Share on other sites More sharing options...
Black Hole Posted January 24, 2014 Report Share Posted January 24, 2014 Brennen, the info contained in it is also interesting to me because it represents the weather here as well. And it also represents weather all across the country from a historical perspective. Not everybody from say Chicago wants to read through the PNW forum on the off chance there are interesting threads. Similarly, you probably don't read their stuff. It would be a shame if some great research went to waste because nobody knew to look at it.

Black Hole Posted January 24, 2014 Report Share Posted January 24, 2014 Basically we want to run this website similarly to the way AmericanWx does from a layout perspective. National disco and subforums for regions.

Phil Posted January 25, 2014 Report Share Posted January 25, 2014 Honestly I think (for now) we should have 4 pinned threads on one forum. - NW US- SW US- Central US- Eastern US This way the community is not divided and will have more opportunity for inter-forum communication and growth. This is how EasternWX got so big. Only when the forums were large enough to warrant subforums, were they implemented over there.

Karl Bonner Posted January 31, 2014 Report Share Posted January 31, 2014 Could you post a similar map for December, Snow Wizard? I bet you'd discover the exact opposite trend in the 500mb anomalies - a sign that over the past 3-4 decades our winters seem to be coming "earlier." January used to be slightly colder than December most places, but the 1981-2010 climatology moved the coldest weather to December, and reduced our winter seasonal temperature lag to pretty much zero!

Glacier Posted January 7, 2015 Report Share Posted January 7, 2015 The '49 to '57 Januaries were absolutely brutal here in British Columbia. With the exception of 1953 and 1955, all of the them were below average. Ironically, 1955 was the 2nd coldest year on record after 1916. January 1950 was the coldest month of all time by wide margin. 20.9C (37.6F) below average in Prince George and Vavenby. I have been told that January 1950 was quite mild in eastern North America, which would follow given that pattern. Quote Link to comment Share on other sites More sharing options...
