Newbie here, any comments appreciated. So the much maligned GFS does seem to have spotted the trend for this weekend before the others with regard to failed very cold conditions....but the last few runs seem to be becoming more and more consistent with some type of easterly flow as per met opinions in Fi. Let’s hope that it’s right this time aswell. However can someone explain greenie high set ups again? While pressure often seems high, on 850’s show dark blues or purples. Is the preffered route to cold with yellows over Greenland or less blue colours? If so what’s the difference?
