That would be perhaps a record-breaker...

While that would be... similar in terms of pressure gradient, but crazy in terms of central pressure.
What ECM and NAVGEM are picking up on is the potential that comes with the southern jet picking up disturbances moving up from the Gulf of Mexico; if any one of those systems positions favourably, it can bomb out.
GFS and UKMO are not seeing that kind of development and that's largely down to them being slower with the disturbance - it reaches a favourable position close to the East U.S. coast rather than in the middle of the Atlantic, and at that time it's not picked up much eastward momentum so it doesn't get nearly as far... or at least, not on the GFS 12z op run. The UKMO run seems to have the trough nearly as slow as GFS but doesn't have the development stage occuring quite so far west.
There looks to be a fair number of those little disturbances entering the Atlantic over the coming week - it's like a game of Russian Roulette where the southern jet is the gun and those disturbances are the bullets 
Although the ECM is only predicting surface winds of 57mph max. Though I suppose that is sustained.
Perhaps more noteworthy is the 10cm of snow being predicted for Northern ireland at 144h on the ECM.
Could be another Oct 87 with those charts 
Quantum: I'll have a friendly weathermans bet with you! I agree with what I am seeing from GEFS i.e a continuing unsettled theme, a little colder next week (high ground wet snow at times, non-settling and very transient) with a colder rain merely being the sad miserable case. Strong winds, gales at times, more flooding. A couple of drier interludes hinted with temperatures closer to average i.e rain for most, hill snow becoming even more likely.... but.... no nationwide 'proper' Beast from the East type of freeze and therefore, nothing which even closely resembles a winter i.e the continuation of a very, very, very long autumn....
The wager would be:
1) Some sign of pattern change by the 15th
2) Northern or Southern blocking by the 20th
The 1st is more of a subjective entry requirment, if the atlantic is raging through at full force and there is nothing in the reliable time frame on the main models then you will win.
The 2nd condition requires strong influence from a scandanavian, greenland*, bartlett, azors, or Euro high or strong mid atlantic high**, or UK based highs (NOT transient ridge) .
*In this case it has to be obvious the blocking is influencing the UK and not just iceland. In all cases dry weather (excepting lake effect wintry showers) should be prolonged in the south east.
** A northerly toppler does not count, since the atlantic would still be pummeling through. Any cold spell produced as a result of a mid atlantic high should last at least 5 days and put the -5C isotherm across the entire country. Any cold airmass that otherwise results from a cold sector of a depression, or a polar maritime airmass (northwesterly usually) does not count. It should be apparant by the longevity whether it is a brief cold sector + ridge or substantial blocking.
Note: Snow and cold does not form any role in the wager; snow in atlantic conditions cannot be used to my advantage, and lack of snow in southern blocking conditions to yours. The key aspect will be a shutdown of the atlantic train, and drier (as a direct result of blocking) weather generally.
If this is not the case you will win.
If you are okay with this?
Eyes down for the 18z....
