At the [url="http://forum.netweather.tv/blog/227/entry-4452-very-early-first-look-at-winter-20122013/"]start of August[/url] I posted a blog entry giving a forecast for the winter ahead now 30 days later it's time for an update.

[b]El Nino[/b]
It's expected to stay in the neutral zone for the rest of this summer. But slowly dips down during autumn. It will stay around the -1 mark through the winter so not as strong as lasts winters.

[b]Introduction,[/b]
Over the course of September and October this year I carried out a experiment to see what weather models performed the best at different time ranges from 24 hours to 144 hours.
[b]How it works,[/b]
Firstly I would let all the models do their 12z runs so none over them had a 12 hour advantage over another. Once they had done their 12z run I would pick a location and each model predicted its thought on it. The models then get awarded points on how close they are.
[
I'm using the Climate Simulator which I've used over the past 2 years and found it to be very accurate for predicting average temperatures for long range forecasts and also I will be using the CFS maps as well. I have compared all of my data to last years to make comparisons and fine tune my forecast.

In 2011 I done a experiment to see how the models perform in 2012 I done the same thing. The experiment took place during September and October. Basically how it works fairly they all make a forecast on the same day at the same time (12z) then when the actual time comes I check the actual weather conditions and see how accurate they were. The models faced tough challenges mainly in September when Hurricane Nadine made the models struggle. The points system rewards the models more points the furt

I've used the CFS monthly mean maps that pick up long range trends for the upcoming months. But I have also used a program called ''Climate Simulator'' to help back up my forecast in certain area's. I used the p
Here are some pictures of what the weather looked from space during the winter. Of course most of the time the UK was covered in cloud but here are the rare few moments when it was clear enough to see.

It was something that got many people talking about what December may hold for us. Some remained positive but for others they thought it wasn't good enough and cancelled winter before it had even properly started.

It's been 4 weeks since the last update and we have seen an interesting end to October a lot colder than expected.
[b]Rainfall,[/b]
November: Below average for Scotland and Ireland but average for England and Wales.
December: Across Northern Scotland slightly above average and for the South West of England slightly below. Elsewhere looks average.
Made using the CFS long range model along with the Climate Simulator.
[b]Rainfall[/b] - Ireland, Wales, South West and North of England, Western and Southern Scotland will see rainfall above average. Ireland especially looks to see the most.

[b]Temperature[/b] - Most of the UK and Ireland look average however there are signs of some mixed mild and cold weather about. Overall Southern England and parts of Wales may end up slightly more milder than average.
[b]Introduction[/b]
Hi all, since 2011 I've done a yearly weather model experiment to find the best performing one.
The previous winners were,
2011 ECM
2012 UKMO
2013 GEM
This time the experiment took part during December 2014. We will be testing the nine weather models listed below,
European Centre for Medium Range Weather Forecasts = ECM
Japan Meteorological Agency = JMA
Met Office = UKMO
Canadian Weather Service = GEM
Global Forecast System = GFS

Hi everyone, well its that time of the month again when I release my monthly forecast. My winter forecast released back in November seems to be doing okay at the moment you can still read it here [url="https://forum.netweather.tv/blog/227/entry-4843-winter-2014-2015-forecast-december-to-march/"]https://forum.netweather.tv/blog/227/entry-4843-winter-2014-2015-forecast-december-to-march/[/url] Anyway here are my latest thoughts on January 2015.

During the winter of 2011 into early 2012 we had some very active Atlantic storms this was due to a strong jet steam. The winter of 2011 and 2012 will not be remembered as a cold and snowy one but we did get some cold weather near the end.
