That ECM chart doesn't show -10 uppers, only around -6 to -7°C. The -10°C isotherm is the start of the 2nd shade of blue (north and southwest of Iceland).

There are still issues to be resolved with the setup upstream. The polar vortex moves into northeastern Canada as a rex block sets up in the western US. I think it'll be more like the end of the week and next weekend before we see any decent winds, as the jet strengthens coming off the american continent the second half of the week, setting the scene for a more southerly storm track.

Thanks for the clarification Su Campu ; however the shades of blue and their corresponding upper temps are not very clear hence the confusion. However I get what you mean about the darker blues to the southwest of Iceland and how they relate to -10 uppers.

The Meteogroup/ ECMWF charts use a slightly higher resolution (increments of 1.0c as oppossed to 5.0c) regarding 850 temps which you may or may not find useful.

Tonight's ECMWF has a strong and blustery SW wind ahead of a cold front this coming Thursday and into Friday:




Potential for coastal gales with strong winds overland but too far out to be certain yet.

Certainly looking quite windy for the end of this week, though nothing particularly "stormy"
Friday evening probably the worst with winds of over 70km/h around the west and northwest coasts.
