Model Output Discussion - New Year and Beyond
Frostbite1980 replied to BlueHedgehog074's topic in Forecast Model Discussion
CFS Now picking up a reversal at 10hpa........although the end of Feb is not ideal this could well be bought forward if it happens at all! -

To be fair it is like all models it can flip flop a bit, however I tend to watch the GFS (green lines) and the bias corrected runs as they are closer to the mark but even two of those just about reverse the winds. Its more looking at trends moving forward for me to see if the trend continues or indeed increases the chances but this is the first time I have seen 2 bias corrected runs reverse the winds at 10hpa. -

First signs of a possible SSW with the reversal of winds moving into Feb, I would take another 2018! One to keep an eye on. -
Model Output Discussion - Christmas week and beyond

I looked at the ens to see how many have some sort of snowy runners around 26th/27th and I found 7 with various degrees. It will be interesting to see if future ens show an increase in this scenario. -

The problem is the closer it gets to the event the more chance there is of it occurring and seeing we are only 5 days away..... -

Can I ask a question please? I know that the op run is at a higher resolution but heard the control isnt, so why do we always refer to the op and control in agreement, when we might as well say the op and perb 25 are in agreement? Genuine question -

Only a 15 degree 850 difference between the control and op at the end -

As I thought the op is very much at the bottom of the ens up to 192 and unless I am reading them wrong there are a fair few warmer options than the 0z. What makes me laugh is some of the ens have a lovely GL high and once again we are stuck in SWerlies. -

Beautiful run by the 6z GFS however we need support from not only the ens but also the likes of ECM and UKMO before I start to take note. My take would be that this is either an outlier or right at the bottom of the pack, however i would be more than happy to be proved wrong. I might just have to take a few screen shots of this run mind -

Thanks for that Chio, does this mean that the chances of a SSW is decreasing if the trop couples in the new year? -

Maybe Chio or Blue will be able to help answer this one -

I Know the vortex isn't coupled but after the beating up of the upper vortex I was surprised to see this.......some of the CFS runs going for a record strength at 10 hpa -

Frostbite1980 replied to Community Team's topic in Forecast Model Discussion
See my post above, Perb 19, although after that, it goes down hill. This is the only ens that shows this scenario though. Sorry didn't read your post properly, no, no op runs just the one ens. -

Will that allow heights to build over greenland though or just a transient NW flow? -

Do you not see a possible recurring pattern in January at the moment then EE?
