Outlook for the next four weeks from the JMA.
Written by Steve Hopley on June 13, 2019
This is the latest outlook for the next four weeks from the Japanese Met Agency the JMA. It is not meant to be a forecast but a general outlook. I have added the 3 images together and rotated them and added a red line so you can see the UK. Blue colours are low pressure area’s and oranges high pressure area’s.
Week 1 13th June to 19th.
Low pressure remains over the UK. stretching westwards into the Atlantic. High pressure is over the eastern parts of Europe. Rainfall is slightly above average for June so we can expect showers and outbreaks of longer spells of rain. Temperatures are still on the cool side.
Week 2, 20th June to 26th.
High pressure over mainland Europe is now also over England, Scotland and Wales. We should start to see some improving conditions. Rainfall will be around average, so there will be some showers but some drier spells too. Temperatures will increase and will be around average maybe a little warmer at times, the exception to this is Scotland and Ireland, were it will be cooler and still quite wet.
Week 3-4, 27th June to 9th July.
This is a two week period but it looks like low pressure will be over the UK again. This may be a slow change from the more settled period the week before. So the beginning of July is looking unsettled again with frequent showers or longer spells of rain. The temperatures looks like being slightly below average.
