Weathergun Posted October 31, 2014 Share Posted October 31, 2014 It has cooled because of upwelling but comparing it to other years, it's pretty warm. NE Pacific SSTs were cooling from late September. Ana's upwelling just enhanced it: http://www.esrl.noaa.gov/psd/map/clim/sst.anom.anim.html Link to comment Share on other sites More sharing options...
cjr231 Posted October 31, 2014 Share Posted October 31, 2014 I love how everyone was saying what a cool and refreshing summer we had this year and yet the JJA average came in at -0.1 degrees, and that's when compared to the warmest 30 year climate block on record. This summer felt so cool and pleasant due to the lack of any real humidity more than anything else in my opinion. Link to comment Share on other sites More sharing options...

REDMK6GLI Posted October 31, 2014 Share Posted October 31, 2014 Paul was going to post something similar to that but im on my phone. Both the GFS and EURO LR models have been showing more of the ridging in the west and troughing in the east as we head deeper into november. Promising feature as we head closer to december Link to comment Share on other sites More sharing options...

Neblizzard Posted October 31, 2014 Share Posted October 31, 2014 Super GFSENS Anologs D+8 and D+11 support +PNA pattern as well: Looks like the low near Alaska is retrograding towards the Aleutians as well. If this is right we could see a sustained +PNA pattern for the second half of November. Link to comment Share on other sites More sharing options...
PB GFI Posted November 1, 2014 Share Posted November 1, 2014 I like to look at the European Ensembles at 500 when looking 10 days out and it`s no secret that last year the Japanese weeklies ruled the LT . Many times last year I would peak at the European 850s on it`s Control run to see where some of the colder anomalies were showing up in Canada . Snow cover over throughout Eurasia and Canada have been posted ad nauseam here but it may be working and by this time next week there is Minus 25 air over the Canadian prairies and Day 10 - 15 is starting to look Colder . So the Snow cover is working early . The 500 MB below will look colder in the east , this is obv a JB idea for those who watch him , but I beat him to it this AM . Look at the trough Alaska and that ridge off the west coast . So expect the tough in the East to get deeper day 10 through 15 Link to comment Share on other sites More sharing options...

REDMK6GLI Posted November 1, 2014 Share Posted November 1, 2014 paul im loving that ridging in the west, I agree that as we head into the middle of November we should start seeing colder than normal air visiting the northeast more frequently. the Eurasia and Canadian snow cover has been nothing short of impressive and will do its work Link to comment Share on other sites More sharing options...

SnoSki14 Posted November 1, 2014 Share Posted November 1, 2014 Awesome looks like we're gonna start to see things finally propagate from above and change our weather pattern. It will also increase the snow threats especially if the cooler than normal weather is present by the second half of November. It's also really chilly but our high temps are skewed higher because they were closer to 50 around 1am even though it's only 43-44F right now and likely to stay that way.

Hailstorm Posted November 1, 2014 Share Posted November 1, 2014 I hope this November's average departure for NYC turns out to be -2.5 like last November. It would be great to see a repeat of that. And what would even be more encouraging is if we start December with high temps staying in the mid-30s for 4-5 consecutive days like last year. That to me is a precursor to a great winter since 2010-2011 featured a December like that as well. Link to comment Share on other sites More sharing options...

Agree, and even in areas that haven't experienced much growth... how much more land is developed upwind of these places, so that the wind trajectory that was once over undeveloped land for maybe hundreds of miles now passes over towns and cities... this may explain the warming of stations that haven't changed much over the years.

96blizz Posted November 2, 2014 Share Posted November 2, 2014 All of which makes the most recent decline that much more noteworthy. If you put these figures on a bar chart it would be a rather noticeable drop so far in the 2010's. Cool stuff. Link to comment Share on other sites More sharing options...
NEG NAO Posted November 2, 2014 Share Posted November 2, 2014 Its unlikely that November temperatures will end up being above normal - as we step down to normal to below normal temps for a good portion of the first half of the month and with increasing snow cover in Canada a trough in the east and ridging out west would also expect the first accumulating snowfall of the season for at least part of the region by months end. Also next weekend looks to be below normal http://www.tropicaltidbits.com/analysis/models/ecmwf/2014110200/ecmwf_z500_mslp_us_8.png Also the indicies all might be in a favorable position together to promote a cold weather pattern in the region as we approach mid month http://www.cpc.ncep.noaa.gov/products/precip/CWlink/daily_ao_index/ao.shtml Link to comment Share on other sites More sharing options...
