Four your country: Dez - very bad weather in the first 15 days, with mild weather, and in the second half of Dezember i think you have a pattern with cold and dry, but with some bad weather too .. Jan - a cold pattern, with some episodes of wetter weather too .. Fev - very cold days for UK !! For Portugal Dec - I hope the first half of the rainiest months in the north than the south, with no lock on Greenland, then a reversal of the negative NAO for the second half in bad weather especially in central and southern Portugal! Above average rainfall across the country and the average temperature Jan - I hope one months like the second half of December, with tb few episodes of dry and cold especially in the second half of the month! Above normal precipitation in central and southern media in the north. FEB - I expect a cold month, but at the same rainy weather with values of above normal precipitation in particular in Central and South! I still a month on average throughout the country although it may be above average in central and southern Portugal! Good luck for me, that i live in the south of Portugal!
