Model Output Discussion - Into Winter
gaia rules replied to MATTWOLVES 3's topic in Forecast Model Discussion
Good bit of eye candy ...to watch that polar high develop ...pull south into russia, build and build and then be squeezed by the atlantic juggernaut (remove the labels press animation rotate to polar view and sit back and enjoy!) https://www.meteociel.fr/modeles/gfse_3d.php?lat=80.25&lon=79&ech=3&zoom=6&mode=1 -
Model Output Discussion - Into Winter
gaia rules replied to MATTWOLVES 3's topic in Forecast Model Discussion
Both ECMWF and GFS have struggled to forecast the low on Thursday. GFS blew it up as we expected by ECMWF doesnt cover itself with Glory either and still 3 days to go. Here are the last few runs on both to compare. -
Model Output Discussion - mid Autumn

UKMO HD brings that second low further north so although in FI still worth watching seeing to see if this gathers traction -
Hi Tilly yes you are absolutely right and I was being a bit gung ho with this weekend's cold looking to become fairly established in the GFS 18Z last night! We just need the cold snap to be short lived (which is a stronger possibility with todays runs as the Iceland high has receded south a tad ) and continuous SW flow in December to push get that 2.04 required.

Model Output Discussion - A cold start to Spring?
gaia rules replied to Cheshire Freeze's topic in Forecast Model Discussion
You can see the difference between the 12Z GFS and 18Z GFS digging in much colder air behind low 2 with ECMWF keeping south in the cold for longer but less cold air behind shallower low -

Your OK in teh welsh valleys The models have finally got to grips with the major snowfall between France and Inverness sometime in the next 10 days. -

Model Output Discussion - Autumn arrives
gaia rules replied to Cheshire Freeze's topic in Forecast Model Discussion
The humidity therefore night temperatures will be important in predicting impact on health. I set up the Heat Health warnings when I worked as health lead at the Met Office after the 2003 European Heat wave and it was the night-time temperatures that mattered more. In France those living above the high floors of tower blocks who died as temperatures cooled from the ground up. The higher humidity meant that there were high min temps. So far the predicted humidity next weekend is very low so although the temperatures are frighteningly high if the humidity stays low and there are no more than 2 nights in a row with minima of 22 then it may not be so catastrophic on health. -

If ECM is on the right track for Sunday then the storm surge team at Met Office will be waking up as that low crosses east coast bang on a spring tide -

While we wait for 18z could someone explain the factors required in N Hemisphere to keep the mid Atlantic block in place from Feb 6th as opposed to it toppling over us again? -
I personally look forward to next week's weather. A possible record breaking low in mid Atlantic possibly below 920mb (which is the weather telling us that the NAO is not at all dead from SSW) and then secondary lows racing in causing severe gales in any area. The winter is far from finished and the word Blizzard could still be returning to this forum anytime after mid Feb because we simply don't know!

Could that monster low forecast by ECMWF GFS and UKMO break any records? With my glasses i make that a central pressure of 920mb! -

Ed Ed a very helpful post.However I dont quite follow your logic that GEM is better because Canada should know its own weather better. My understanding is that all models use the same global data and so it is a level playing field. It is also has to be a global forecast although each country chooses to increase the resolution over their patch. GEM therefore just have a better model this week. There is a forum topic of How the Models Compare at Keep posting! -

I'm not so convinced of their accuracy even at 72 hours. When it comes to modelling snow I wouldn't trust any forecast beyond 36 hours particularly for Monday/Tuesday event that is changing with each run and Ian F is now thinking it will all shift west. -

Saturday's snow (or no snow) event is In range of the NAE....together with the GFS pushing the low further south its not looking great for snow lovers. -
I agree that this is a really good update. Like Thunderman I would be very nervous working at the Met Office regarding the possible snow this Saturday! If the rain is very heavy and there is a significant cold undercut surely that boundary between rain and snow is still totally uncertain and could be anywhere!

Just looked at the T144, T120 and T96 from the GFS all for Sat 12:00 pm. Each run shows the progressive drop in pressure over the whole of Northern Europe and rise in pressure over Iceland. The scandi high stays pretty much the same. The low to our SW in particular deepens and carrys more energy with each run so could become more nasty.
