Please can you explain. I have read the name Johm Hammond a few times on here today,  Are you referring to a well known weather presenter? If so what has he said? thanks?

Yes him. I said on Twitter that the been were saying mild and no snow mentioned. And he said 'give it time... '

It's the one west of Iceland that concerns me, the more it sticks to the PV chunk the better but, this run, it's separated itself again. Still time for recovery but that would spoil any clear flow.

I think that's the one that causes this one to the E of Iceland to develop tbh though.

Re Mr Hammond and time: Are we talking about creating dinosaurs or the potential for a cold spell?

Eh!,the more it splits from the main chunk the better as it sends more energy south.

No, as we saw on one of the runs yesterday, it just acts as a spoiler and holds up the main chunk of PV that is getting shunted our way on a NW/SE axis. On that run it became jumbled with another system and mixed out the colder air.

EDIT: Actually looking pretty good now, eastern pacific ridging positioned well, azores high being suppressed, incoming system becoming elongated. What could possibly go wrong?!?

Just one last thing (promise I wont bother anyone any more), not actually sure exactly what frictional torque (just seen it is a pre-cursor to mountain torque) is but presume its linked to the GWO and angular momentum (is it the frictional effect of wind against the earth surface?) - I  already know the very basics of MT, although cant remember which one is _+ and -, whether high pressure to the east of mountain trange or west.

Positive torque transferred to the atmosphere with a ridge to the east and trough to the west of the mountain range.

Frictionals = yes: surface friction created by atmosphere on the surface. The relationship between atmosphere and earth has a see-saw motion - in perfect equilibrium both atmosphere and earth would rotate in perfect harmony... but forcings from weather systems, mountains, ocean temperatures all work to put this out of balance. Frictionals constantly work to try and regain that equilibrium and so you can be sure that if GLAAM is negative there will be a positive frictional response to try and rebalance things. Analysis has shown that when frictionals rise they create poleward waves and these then create mountain torque events - therefore usually a MT torque spike will follow a FT spike.

And just to add to infuriation, Ben Stokes has now been added to Englands T20 squad when they said the reason he wasn't selected for the Ashes was because of his case not being settled yet - more lies and BS from the ECB.

How does he feel about the ECM?

 

or is he in the GFS camp?

Very progressive, great for northerners. has been shown before around 15th for a cold westerly, transient snow for south maybe too, best hope I think of snow falling

First run today that's weakened the Scandi block.  Slider incoming and to be fair the uppers seem pretty good for the NW

Easterly not on, never has been, we should all pack up and go to sleep. Silly bunch aren’t we. ?

ECM, UKMO and even the gfs show that there is just a chance we might get an easterly in the 6-10 day period, not a high chance ill admit, but it’s on the table 

heres the big 3 at 120

Jet starting to take a dive at 174h, could be okay, still but more likely taking most of England out of snow range if it doesn't increase the angle.

You was mentioning the one to the west which was attached to the main lobe,i wasn't mentioning the spoiler running in front and traveling NE,i was talking about the low south of the main chunk breaking off SE'wards.

PM weather, or in other words for those in the south... rain with a freezing cold wind! Oh the joys.

i really hope the GFS isn't right, at worst I was hoping for a dry spell, even that appears unlikely if the GFS is right.

Don't pack it in just yet, the 18z has, and will, never decided anything! The GFS inconsistency alone shows how complex this situation is.  I'm giving it one more day before throwing the towel in.
