Model output discussion 25th Jan onwards
Robbie Garrett replied to Paul's topic in Forecast Model Discussion
Actually I take a look at the GFS and think, hmmm maybe it's a long route but there might be some changes afoot. Look at the vortex over Canada. Then look at it next Wednesday. 144 hours. That's a pattern change at H500hPA! Look at the Azores positioning, it's ridged westerly into the Atlantic. so it's highly unlikely to fill eastwards with trough movement east? One way it might go is northwards depending on any troughing left over Canada pushing everything northwards from the south. i.e warm air Advection from the Azores. Just my thoughts, nothing professional but I am wondering if the strat takes hold, the Azores is in a very good position to build blocking, with a vortex over Russia pumping towards us.. -
I remember back in the 90s that it never stopped raining, admiringly I think Spring will be seasonal maybe warmer towards the end and Summer should be amazing (again??) - rainfall wise I can see next winter maybe being the same. I've noticed we tend to get cold when it's dry? and lots of snow? Is there a correlation of drought and snowfall/northern blocking?

Model output discussion 25th Jan onwards

Pretty Average IMHO - I think this Winter is a mild/wet blip a bit like the one we had in 2012. I think that the relentless rain is because of the good Summer we've just had, all in all I'd say this winter is pretty average = normal (maybe very wet) but what do you expect when we had hardly any over the Summer. No let down in the precipitation either.. -

The BBC weather update is about as positive as the world's economies. Pretty chilly this week I'd say. But it does look like a return to what we've had most of this winter. -
Coldest Temperature record for Winter 2013/14
Robbie Garrett replied to Barry12's topic in Spring Weather Discussion
Yeah very long time ago, I guess that you'd need -20*C uppers at 850hpa and clear skies, no wind and December 2010 style snowfall. -
2014 - Heathrow January... 59.94mm so far with an average of 2.44mm - MAX 9.9mm 19.04 mm in 2013, and 0mm in 2012 (LOL) From October 25th to January 25th we've had 5.31 inches of rain.134.9mm

Coldest Temperature record for Winter 2013/14
Robbie Garrett replied to Barry12's topic in Spring Weather Discussion
I do wonder if the −21.1 °C in London will ever be broken. -
Definitely the Azores looks to ridge northwards on the NCEP, but does it really get there? Personally sometime next week we will start to see what happens with reference to the pattern change and a block out towards the west/north west in this part of the hemishphere. I was looking at November 2010 and it took quite a while for the blocking to take hold, I guess because that was just synoptics and this time we are awaiting for the Polar Vortex to be obliterated by a SSW. The low resolution output paints a picture of low pressure across the UK, with no real change to the current setup. The ensemble means don't really show anything but very similar weather to what we have now. Jetstream practically running NW/SE across the UK. It's a long route to prospects with no real definitve hope and I wouldn't get so happy yet with the models, it's probably a waiting game on the strat.

Does anyone remember February 2011? -
spring 2014 Spring 2014 Discussion
Robbie Garrett replied to Skullzrulerz's topic in Spring Weather Discussion
I would love April/May to be extremely warm and Thundery, like an early Summer leading into a glorious June. Mid 20's in April/May can be so refreshing and the air can sometimes be nice and clear. -
Model Output Discussion - 10th Jan Onwards
Robbie Garrett replied to Paul's topic in Forecast Model Discussion
CFS till end of February on both 1 and 9 monthly for the daily outputs are not showing anything remotely interesting for the foreseeable. Looks as if the mobile westerly pattern is set to continue till at least end of February. With a Polar Vortex where it is now, I cannot see the end to this relentless run of very wet weather. Although the GFS has sparked some interest for me, Chunk of polar vortex over Newfoundland and the rest is Scandinnavia in this part of the N.Hem. High pressure over Azores sending warm air advection towards Greenland and thus a 1060hPA high. First signs of the SSW coming into the modelling systems. I think that the only route to cold now is of a Sudden Stratospheric Warming, doesn't look likely that synoptics will play a part in changing the weather pattern and thus the overall picture. Read what Matt Hugo has posted on his twitter. NCEP Ensembles paint a picture of some sort of changes. TODAY NEXT Thursday EARLY FEB, things looking blocked... -
Somewhat my thinking that this Summer is the return of the monster storms. A lot of energy in the atmosphere, lots of heat and moisture but the jetstream still throwing those killer lows towards us providing a massive bang at the end of each hot period. Although I'd take consistent plumey weather over Block vs Low pressure.

Model Output Discussion 17th Dec.2013-12z onwards.
Robbie Garrett replied to phil nw.'s topic in Forecast Model Discussion
Is it possible for the jetstream to maintain it's momentum and head south or in it's current position it would be strongest? Just wonder if it could provide some undercutting lows rolling into an easterly like Feb 2009. -
