That damned stratosphere looks threatening to me! At least at 200 mb if
you know how to interpret the charts from GFS. Just look at that polar
vortex migrating SW'wards next weekend, ooh er!

I wouldn't have a clue how to interpret a 200mb chart but the GFS
sea level pressure charts from early next week onwards seem to show
generally zonal conditions.

I've noted that the last few operational runs have seemed to show that
with an unusual degree of consistency, but then right at the end of the
period (ie around the 19th) they show pressure rising over Scandinavia.
Obviously it would be unsafe to read too much into that at this stage.
(But the end of January and into February is when Scandi Highs seem to
have formed most frequently in the past.)
