Current Synoptics and Alps Weather Summary

Last week was a largely mild one across the Alps with mild South South westerly winds within a tropical Maritime air mass

If we look at today's chart (left) and compare to the forecast charts from the last blog (right) we can see the general weather pattern is very similar, however the low pressure  is slightly further to the west, however the High pressure is very much still dominant over mainland Europe, and if anything stronger than previously forecasted.

Upcoming Synoptics

It is very much a case of deja vu for the Alps synoptics this coming week. Winds generally come from the West to South West. Which means it largely remaining on the mild side.

There is a time around the middle of the week, though that there is a chance of some colder weather snipping for far East of Austria.

You asked for comments Julian. Well first of all could I say 'thanks' for taking up your time to do these blogs every week. They are a 'must' read for me.
With regard the format, I think it's a good balance and provides a concise but informative picture of the upcoming weather for the Alps.

Maybe it's a personal preference and others might disagree, but I always look at the 850hPa charts when watching a model run unfold, as the temperature isotherm is what most resorts will experience at 'mid-mountain' height. But I do acknowledge the charts can be very messy when compared with the neater looking 500hPa charts, and which still very adequately convey an at-a-glance take on the overall synoptic pattern. (So please feel free to ignore me!).

Finally, we have several readers of the thread that ski regularly in the Pyrenees, so maybe those mountains could be covered from time to time - say when a weather event is set to impact in the week ahead? (With apologies for suggesting more work!).
But once again, thankyou. :)
