Parts of France continue to see temps near 30 4 day's off November on this morning's ECM

So even after the first trough disruption fails, ECM still sets up the dug-down low near the Azores by day 10, while having built a mighty plume of heat to the south - and yes that is actual 'heat' not far south of us, as Gavin D handily highlighted this morning. 

Starting to wonder if the Halloween Heater will be seen for the third time in four years... I'm having to get used to having birthdays with early-mid-afternoon temps near 20*C!

After all the excitement of this week, the Atlantic goes into snooze mode, not to say sunbathing for a couple of weeks. But if you credit GFS at long range, the weekend of Nov 4/5 will be a bad idea for a bonfire party. Miserably cold in addition to rain and wind.

Continued signs on the 18z of a notably warm end to October. I am starting to think we are going to get a record warm Halloween. Insane charts with the 564 dam line in the south. 20c plus maxes?

Quite nice in seeing these warm plumes being shown. 20c by the end of the month? Yes please!!!

Quite funny as I believe it was The Star (not the Express this time) which wrote a piece (about 7-8 days ago!) on the likelihood of a record-breaking warm Halloween. They could be right.... for once.

Quite a few chart forecasts have hinted at a cold spell in the first week of November.

Wouldn't surprise me, the weather always turns cold around Bonfire night. You could bet your house on it.

Lots of cold air moving into northern Europe next week

http://www.wxmaps.org/pix/temp4.html

GFS, and to a lesser extent ECM, show an Arctic rather than Siberian origin fr this air

http://www.meteociel.fr/modeles/gefs_cartes.php?code=0&ech=168&mode=0&carte=

I'm quite happy for the cold air to stay there for now if we can draw on it come January

That seems to have been a bit of a trend in the last few runs across the models. If it lasts for about 6 weeks we could be in business.

Quite similar 12Z to late October 2012, snow fell really quite far south and it was the earliest snow had fallen in several decades at least.

The snow row numbers starting to appear on the GEFS charts might be as close I/we will get for a while!

For what it’s worth the ECM op run is similiar to the GFS run (not that either are snowy for the record!)
