This is the outlook for the next four weeks using the JMA issued by the Japanese Met Agency. This is just one model the JMA but followers will know that I normally publish it every Thursday or Friday. I have added the three images together and I have rotated them and added a red line so you can see the UK. Blue colours are low pressure areas and orange’s colours are high pressure areas.
19th July to 25th.
High pressure over the UK with a high pressure ridge over Scandinavia. Low pressure is over Southern Europe and Greenland. This will bring very warm temperature around 2 or 3 degrees above average. It is looking mainly a dry period.
26th July to 1st August.
High pressure close to the East side of the UK over central Europe and over Scandinavia. Low pressure from the West coast of the UK and Ireland and over the Atlantic. Temperature look like remaining very warm around 1 or 2 degrees above average for the end of July. This period looks like we will see rainfall slightly above average, so it will become wetter.
2nd August to 15th.
Not a great deal of change in air pressures positions around the UK. We will see little change in the temperature from the previous week, so remaining very warm but again rainfall looks to be slightly above average, so wet at times.
