This is the outlook for the next four weeks using the JMA issued from the Japanese Met Agency. I have added the three images together, rotated them and added a red line so you can see the UK, Blue colours are low pressure area’s and oranges are high pressure area’s.
Week 1, 16th to 22nd November.
High pressure will be in control during this period. It will start off chilly then the temperature will rise and will be 2 or 3 degrees above average. Rainfall will be slightly above average.
Week 2, 23rd to 29th November.
High pressure over Greenland with low pressure to the South West of the UK over the Atlantic. This brings slightly above average rainfall and temperatures around would you would expect for the end of November.
Week 3-4, 30th November to 13th December.
This is a two week period, and the air pressure over the UK remains much the same as the previous week. Temperatures around what you would expect for early December with rainfall slightly above average.
