In this sort of event the meteocentre website has become a firm favourite:

http://meteocentre.com/models/compar...lang=fr&run=12
&hour=072&range=glb

This sort of plot shows really well the comparison between some of the
model runs - and how the models are still agreeing pretty well on a rapid
cyclogenesis event with all the models displayed on exactly the same
footing on the same page (although the EC plot is bereft of the thickness
lines).

GEM 943mb, EC 945mb, UKMET 946mb, GFS 954mb. Interested to see the GFS
model is lowest of the 4 - my own impression is that it tends to overdeepen
lows. Got no particular statistical evidence on this, however !

Interesting to see another low following on after which might give a bit of
a sting Tuesday/Wednesday.
