Model Output Discussion - January 11th.
ICETAB replied to Osbourne One-Nil's topic in Forecast Model Discussion
That forecast is poor compared to what we have seen in previous days. Not good IMO -
Model Output Discussion - 8th - 14th January
ICETAB replied to kold weather's topic in Forecast Model Discussion
Even though we miss the initial easterly we still have the building blocks for deep cold. I see allot of potential following on from the 240h chart -

ICETAB replied to chionomaniac's topic in Spring Weather Discussion
You are mistaken. Solar activity did indeed increase but it was far from normal. In the last two months it has reduced significantly and remains low/very low- 1,324 replies

Model Output Discussion - 1st - 7th January
ICETAB replied to J10's topic in Forecast Model Discussion
Subtle improvments showing on the 06z GFS. It should develop into something more interesting down the line. High pressure looks a little more robust further north It would be nice to see the GFS start to back the GEM. Is the GEM a German model? -
Model Output Discussion - 1st - 7th January
ICETAB replied to J10's topic in Forecast Model Discussion
The 240 chart on the 0z GEM model is the chart of the day for me. Shame it's cannon fodder! Edit: I think it's actually the best chart of the season -

Model Output Discussion - 26th December - 1st January
ICETAB replied to reef's topic in Forecast Model Discussion
Looking promising for a colder pattern on ECM at T216. Blocking appearing to our north? -
Model Output Discussion - 26th December - 1st January
ICETAB replied to reef's topic in Forecast Model Discussion
It's only out to T168! Are you looking at the northern hemisphere charts? -
Model Output Discussion - 19th - 25th December
ICETAB replied to reef's topic in Forecast Model Discussion
A very different pattern emerging on later frames of the GFS. A sustained northley blast could be possible... I hope we keep seeing these sort of charts going through Xmas -
Stratosphere Temperature Watch 2011/2012
ICETAB replied to chionomaniac's topic in Spring Weather Discussion
So if the warming continues to strengthen in the current position it is likely that blocking will occur over the Canadian sector, making colder conditions unlikely over Europe?- 1,324 replies

Model Output Discussion - 12th December Onward
ICETAB replied to Paul's topic in Forecast Model Discussion
The northern hemisphere view for the 240 ECM looks a little more promising to me. High pressure building of the arctic. Could that ridge forming migrate further north and split the vortex? -
Model Output Discussion - 12th December Onward
ICETAB replied to Paul's topic in Forecast Model Discussion
Does anyone know how well the CFS predicted the last 3 cold winters from this sort of range? -
Model Output Discussion - 7th-13th November
ICETAB replied to kold weather's topic in Forecast Model Discussion
I stand by my initial assessment. I think it will turn colder at the end of next week and I fully expect to see northern blocking to start showing in the model ouputs. -
Model Output Discussion - Early November Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
GEM @ 240 h looks interesting to me. It could go on to develop a GH. After viewing this mornings model output I have no reason to change my current view of a cold spell ariving from around the 18th, maybe a little later. I think the models should start to pick up on this over the next few days. http://www.wetterzentrale.de/pics/Rgem2401.gif -
Model Output Discussion - Early November Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
Agreed, I cannot see any changes in the reliable. I expect this to change next week though. GFS has been showing signs of a cool down in FI for a while now, have you noticed this? -
Model Output Discussion - Early November Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
00z GFS continues to suggest a pattern change around mid-month. I still say we will get the first taste of winter on the 18th. That conclusion is not based on one run. I have seen a pattern change showing on the 00z GFS over the past four days. I live in the NW so the current FI synoptic setup showing on this morning’s GFS would suit perfectly -
Model Output Discussion - Early November Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
I disagree with your view. You are correct in saying that FI is what it says on the tin, however it is about picking up trends and GFS has been consistently leaning towards northern blocking in its later timeframes for the past 3 days at least. I think it might just be on to something. I personally believe that we will be in our first cold spell from the 18th November. We may not see widespread snow, but it will feel like winter everywhere. ECM does not go out far enough to compare against the GFS. -
Model Output Discussion - Late October Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
I have a sneaky suspicion that if the ECM went out further we would see the high pressure building to our west, migrating north east. Obviously this is pure speculation at this point. Looking beyond T168 should be classed as a bit of fun. Verification after this point is always poor. I do think we will see a colder trend emerging as we go through the weekend though. It looks like the AO forecast is going towards a negative phase? -
Model Output Discussion - Early October Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
FI on the ECM looks interesting tonight. If only it was december! -
Model Output Discussion - Early October Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
Well the models can't lock down the likely longer term outlook at the moment. I see the AO forecast is pretty much split between going strongly negative to weakly positive. I think this uncertainty will be reflected in the models over the next few days. My bet is that we will see it take a nose dive leading up to November with plenty of northern blocking showing up in model output later this month. Just a hunch... -
Model Output Discussion - Early October Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
Downgrades! If the last 3 winters are anything to go by then I'd say we will be looking at upgrades over the next few days... Bring it on. I'll stop ramping now. -
Model Output Discussion - Early October Onwards
ICETAB replied to kold weather's topic in Forecast Model Discussion
OMG ECM is looking cold going in to FI. This pattern is becoming the trend on all models. I think we're going to see an early start to winter. Its a good sign seeing these kind of patterns being thrown up. -
In Depth Model Discussion, Analysis and Summaries
ICETAB replied to Paul's topic in Spring Weather Discussion
I was thinking of Glacier Point. Steve Murr is of course a legend in his own lunchtime. So GP has not been posting this summer/autum then? I'd like to get his view on the situation for the coming winter. -
In Depth Model Discussion, Analysis and Summaries
ICETAB replied to Paul's topic in Spring Weather Discussion
There was a chap that posted detailed analysis of teleconnections and his view on the impact it would have on the weather. I seem to remember his forecast being very accurate for the past two years. Does anyone recall his name and know if he has posted his thoughts for the coming winter. Sorry bit off topic! -
