The cold slightly further North on this run in comparison to the 00z? Either that or the cold pool is slightly narrower, meaning I now just get a brief flirt with the -10 850 iso.
Not sure if that little shortwave @ ~T42 just off Brest has anything to do with it. That was not there on the 00Z.
Still there looks to be a fair bit of wintry ppn arround in the channel, its just whether surface conditions are conducive enough to allow it to settle. I guess only time will tell.
